Which Burn Pot Liner is Correct for my Enviro Pellet Stove?

Buying pellet stove parts online is convenient. Just type "Enviro" and "burn pot liner." A quick search can find you just what you need.

But your search might return multiple results. Enviro EF2 burn pot liner, Enviro Maxx Burn pot liner, Enviro Windsor burn pot liner. You see a bunch of part numbers. You think to yourself, " I know I have an Enviro stove, but I'm not sure which model." This happens often. We've known customers who move into a new home that comes with a pellet stove, but the former owner doesn't tell them what their stove model is.

Do not go by just what the burn pot looks like in the photo. Some Enviro burn pots look similar, but come in different sizes.

If you have the stove manual, that's a great start. Often, those have a parts list or at the very least, they will tell you what model stove you have. All of our parts listings on East Coast Hearth state the stove model, so for example, if you know you are looking for a burn pot for Enviro Meridian, then you're all set.

But lets say, you don't have a manual. Getting a used stove can be a great value and it gives a great pellet stove a new home, but often the new stove owner doesn't receive a manual. The first place to check for the stove model is the back of the pellet stove. It also may be found underneath the hopper lid.

Occasionally, on an older stove, the lettering on the stove might be worn or hard to read. If you can't figure out which model Enviro stove you have, please contact customerservice@eastcoasthearth.com. We'd be happy to help. If you attach pictures of the front of the stove and the control panel, we can identify the model for you and send a link to the correct burn pot to order. You may also measure the dimensions of the burn pot and email them if you wish. We've serviced many Enviro stoves, so we've seen them all.

We've included a chart of burn pots liners, part numbers, and the stove models they fit below. Remember, some Enviro stove models have similar looking burn pot liners, but they are NOT identical. They cannot be used to substitute for each other. Make sure you identify the stove model or ask us. You may click on the pictures and part numbers to view product pages. Many of our product pages show the Enviro burn pot dimensions.

How Fire Brick Insullates the Stove, Reducing Harmful Emissions & Producing Optimum Heat

The fire brick found in the back of the firebox of most wood and pellet stoves serves an important purpose. Fire brick helps optimize the stove's heat output and produces a cleaner burn, benefiting the environment. In many stoves fire brick also ensures proper heat flow. The fire brick insulates the heat inside the stove, reflecting the heat off the boards instead of letting it get absorbed by the stove walls. This increases the temperature inside the stove which transfers more heat through the heat exchanger so more heat comes out the front. This helps keep your room toasty.

For some pellet stoves, it is an intricate part of the design. Whitfield stoves for example, have an exhaust chamber behind the firewall where hot exhaust smoke travels. The fire brick encloses this chamber. Because the fire chamber doesn't have a wall of its own, the fire brick is an absolute must for the exhaust air to flow properly behind it. Without the fire brick, hot exhaust smoke would come back inside the firebox and not be channeled properly to the exhaust blower and venting.

The way fire brick insulates heat also reduces harmful emissions, benefiting the environment. It is actually one of the key reasons fire brick was developed. Back in the early 1970's there weren't any restrictions on emissions from wood or pellet stoves. That changed in 1988 when the EPA established
emissions standards. Engineers discovered that in order to achieve a cleaner burn, it was necessary to put firebrick in the combustion chamber to make it hotter. This insulates the heat inside the firebox, making it hot. Ideally, it creates a temperature of over 1000F. This burns more harmful particles in the smoke such as hydrocarbons so they are not released into the air.

Designing an area inside wood or pellet stoves that maintains sufficient heat for complete combustion required engineers to improve how stoves are insulated. Baffle boards and blanket insulation were invented for this purpose. Baffle boards are a type of rigid insulation such as fire brick, whereas Blanket Insulation is soft insulation behind the firewall in the back of the stove or behind a metal plate in the back of the firebox. Fire brick baffle boards have the benefit of not having to be installed behind something. They stand on their own, better deflecting heat off the stove walls. They can be made to look like real brick, which creates, a warm homey look.

Secondary combustion is when more warm air is introduced into an already high temperature zone or secondary chamber of the stove. Usually, the hot air comes through a combustor into the secondary chamber. Many modern wood stove manufacturers use catalytic combustors because they burn smoke at low temperatures, releasing chemicals to burn the smoke better, but most pellet stove manufacturers achieve a cleaner burn through higher combustion temperatures.  For pellet stoves it is not necessary to use a catalytic combustor because pellets do not include tree bark, so those impurities don't have to be removed.

Baffle boards or Firebrick were originally constructed of cast iron or actual brick, but these materials did not provide sufficient insulation to reach the high temperature required to achieve a
clean burn. Vermiculite based fiber insulating boards were then designed into many stoves. Now many stoves use ceramic boards.
Ceramic fiber boards can be used with stoves with fire temperatures as high as 2200F.

We sell the OEM as well as durable after market Fire-Tek fire brick

Superwool fiber for baffle boards is a customizable fire brick alternative if you have an older stove with discontinued parts or your stove didn't come with fire brick and you'd like to maximize combustion. It is available in different thicknesses, and can be custom cut. It has low bio-persistence and can with stand high heat like ceramic boards. There are examples of proper use in the link blow in the product pictures.

Door, Ash Pan, Glass, Hopper Lid Rope Gasket Maintenance & Why I Recommend Graphite Gaskets

 

I have replaced many rope gaskets while servicing stoves. These gaskets are important for keeping a pellet stove air tight for a lively flame and maximum heat. From my experience, after 3 or 4 years, these rope gaskets become frayed or hard and brittle and need replacement. These rope gaskets are used on the Fire Door, Ash Pan, Window Glass, and Hopper Lid. Round rope gasket is used for fire box doors and some ash pan doors. Door rope gaskets come in different diameters from 3/8" on Harman pellet stoves to 7/8" on large Travis stoves. These gaskets prevent room air from being sucked into the fire box. If they are not doing their job, the flame becomes lazy and won't provide as much heat. Flat rope gasket is used for ash pans, ash doors, hopper lids, and window glass. I always recommend premium quality graphite impregnated rope gaskets for best results. Here's why.

 I installed a brand new pellet stove using my prior experiences. I even watched an installation DVD to make sure I knew all the requirements for that specific stove. However, after a few days my customer called because the fire door was jammed. I had not expected this. I went back to figure out what happened. Using my screw driver, I carefully pried the fire door open. I had to try different angles before it finally budged. I found the standard white rope gasket that comes already installed on the door may stick and cause a door jam. The pellet stove I installed was brand new and I had not altered the door gasket in any way. Graphite impregnated gaskets won't cause this problem. Graphite is slick, which keeps the door from sticking. Since the graphite gasket won't stick, it won't get frayed from sticking to the door as it is opened and closed over time. For this reason, graphite gaskets last longer and may not need to be replaced as often. I still recommend to check them as you perform regular maintenance of course. See below for instructions on how to replace the door gasket.

You can find a graphite gasket for your stove by clicking here

It is also important to replace hopper lid and ash pan gaskets regularly. Hopper lid gaskets take flat rope gaskets often called Tape Gaskets. Hopper lid gaskets prevent air from being sucked into the hopper that could feed a hopper fire in a burn back situation. This problem is not common, but it can happen so it is best to take the necessary safety precautions. Check your hopper gasket if you have one and make sure it is not frayed, worn, hard, or brittle. If so then replace them.


Ash pan gaskets also use flat tape or flat rope gaskets. Some ash pans are open to the fire box, so a good seal is necessary to ensure a lively flame. A dollar bill test can be employed to check the door and ash pan gaskets. Open the door and lie a dollar bill across the gasket and latch the door shut. If you can still pull the bill out, this indicates a poor seal. This test should be repeated for all 4 sides of the door. Sometimes, the latch can be adjusted so the door shuts tighter. If the test still fails then the gasket should be changed.


Some flat gaskets come with tape that peels off the back. These can be used for replacing the window glass gaskets. They don't need to be replaced quite as often, but they do get frayed so they should be checked occasionally to ensure the fire door window glass is tightly sealed. If the glass breaks, they should be replaced along with the glass.


The door gasket can be replaced with just a few simple steps:

1. Pull out the old gasket. You can pry it with a screw driver if stuck.
2. Remove all glue and residue remaining from the old gasket with a wire brush or a wire wheel on your Dremel or drill driver.
3. Apply RTV high temperature silicone to the channel where new gasket will be installed. I prefer the way clear silicone looks..
4. Start laying in the new gasket. I prefer starting from the bottom corner on the side since it cannot be seen easily. Some manufacturers say to start in the middle, but from my experience the corner works best.
5. Close the door and latch it until it dries so the silicone sets up properly. You may also close the door on newspaper to ensure the silicone will not glue the door shut! I prefer to close the door and latch it, then open the door and wipe any excess silicone. This ensures the door will not be glued shut and is more professional because excess silicone stuck to newspaper is messy and difficult to clean up.



Always check your rope gaskets once a year for an optimum flame and safer heating season.

Normal Pellet Stove Operating Sounds VS Sounds That Indicate Faulty Components

 

 

As a pellet stove professional, I've found that identifying the sounds a stove makes or doesn't make is essential when diagnosing and fixing it. I always start by determining whether the sound in question is a normal operating sound. If you are the landlord or you are not the person who usually operates the stove, consult with the stove's user since that person will be most familiar with the stove's typical sounds. I have included a chart below that compares normal sounds to problematic ones. I'm going to share some tips on how to identify those sounds based on my experiences.

The other day, one of my customers said there was a strange squealing sound coming from the pellet stove while it was running. He asked me what it might be. After a thorough cleaning we restarted the stove and it made that sound again. The squealing happened intermittently, repeating every few seconds. Since the sound was repetitive and located in the center of the stove, I could identify the auger was making that sound. It squealed during a small part of it's 360 degree rotation. I gave the auger a complete servicing, which remedied the issue.

Listening to the sounds your stove makes can resolve many other issues. Doing so may help identify whether the exhaust or convection blower has gone bad. Another customer told me that the pellet stove sounded like a jet plane after it warmed up. Instantly, I knew  the convection blower was the issue since it is the only part that starts running after the stove heats up. The stove gets hot after the start up cycle finishes (approximately 15 minutes). Upon further inspection, I discovered it needed replacing because the bearings were bad. A different stove had a squealing noise that occurred right when the stove was turned on. It came from the left side of the stove where the exhaust blower was located. Of the two blowers, only the exhaust blower starts running right  away; therefore, replacing that part was the cure.

No noise at all can also indicate your stove's issue. I came across a unique issue when testing a stove. It ran for 5 minutes, then went silent. All of the lights on the control panel went out  he stove died. Having no sounds in this instance helped me pinpoint the AC line cord was the issue. After the stove got warm, one of the line connecters had failed. Replacing the line cord fixed it. Also, a multi-fuel stove I worked on didn't make a sound in the burn pot. After investigating, I found the rod connected to the pot stirrer motor was so loose it prevented the stirrer from turning.

  Listening to where the sound is coming from and, if possible, seeing the moving parts helps find problem areas. Knowing where the stove components are located is helpful as well. Determining whether an unusual sound occurs intermittently or constantly, or varies with the component's speed is valuable information. If the sound happens promptly as the stove starts, then the faulty component could be the combustion (exhaust) blower,  auger, or auger motor. If the sound is heard after the startup cycle, then the faulty component could be the convection (room) blower. Once you identify the part in need of potential replacement, I recommend using an AC test cord and multi-tester to test this component for abnormal sounds.   Sometimes, the noise only occurs when the stove is hot so a test fire is always needed to complete the analysis or assure the repair has been made. I always give the stove a complete cleaning and lubrication first, then perform the test fire.

Wi-Fi T-Stat for a Wood Pellet Stove - Ecobee EB-Stat-02 Detail w/Install Pics

 

Do you want the best Wi-Fi Thermostat that easily connects to your wood pellet stove or any heating type of furnace?

Here is the new Ecobee EB-Stat-02 with free dowloadable app for your smart phone. :)

The install can be smooth if the install location is known and the wiring length is planned out.

This T-Stat is one of the very few that is not only 24 volt but also can be used on a Milli-Volt system with the optional AC adapter!

The Install outlined and pictured below was done on an Enviro Hampton GC-60 but will work on any pellet stove with a standard T-Stat hookup on the control panel. Most newer stoves with digital control panels will except this T-Stat. This T-Stat does have the short cycle delay needed to give the pellet stove time to turn on or off properly.

 Most newer models of the following stoves will work such as:

Enviro, Regency, Avalon, Lopi, Breckwell, Whitfield, Napoleon (NPS-45 or NPI-45), Hudson River, Magnum, US Stove, Pelpro, Glow Boy, Englander, Archgard, Osburn, Enerzone

 Install steps.
0. Turn off the stove or heating appliance and unplug it.

1. Choose the location and mount the control unit near an AC outlet if possible.
Use wall anchors or wood screws.
If you have the optional remote module, mount that into the control unit first.
Not too close to the stove but not too far away maybe ideal

2. Mount the Head at the normal height on the wall approx 5 feet off the floor.

3. Run 4 conductor solid jacketed wire from the control.
If using hide channel like I did mount that on the wall first.
I used 5 cond. T-Stat wire from Lowes

4. Connect female spade lugs on the regular 2 cond T-Stat wire and plug into stove.
Run wire to RH and W on the control box.

5. Plug control box into the wall.

6. Run the Install wizard on the T-Stat touch screen to choose your Wi-Fi router name and lock it in.

7. On your Iphone
Download and install the Ecobee Smart Stat app from the App store.
Don't forget your apple Appstore password. :)

8. Set stove to either Auto-On/Off or Auto-Hi/Low

Now you can either setup a daily program schedule for your stove or put the set temp on hold and change the set temperature up or down to what you desire from anywhere in the world.

Yes, it does have the short cycle delay for the pellet stove.
What I like is the button for the weather forecast and the optional remote module for additional sensors. Also what you see on the wall stat is also what you see on your smart phone!
1. Indoor sensor
2. Outdoor sensor
3. Humidity sensor
4. CO2 Sensor

Pellet Stove Evolution & Parts Replacing

 

                                                                        

 

 

 
A pellet stove is a modern heating appliance that uses sawdust compressed into wood pellets, a very green renewable and inexpensive fuel. True multi-fuel stoves use a burn pot stirring rod that keeps ash, especially corn ash from fusing together. These stoves burn compressed wood pellets, corn, soy beans, cherry pits, olive pits, bio mass fuel grains and processed silage with only a few simple adjustments.

  Some early units are a hybrid design, reincarnating some wood stove features. Like a wood stove, these models have a top 6 inch flue pipe and use natural drafting. However, sawdust woo
d pellets need a strong air flow to keep them burning. Initial designs sometimes have a positive draft blower connected to the intake air pipe to force room air through the pot of wood pellets to burn them completely. Many of these stoves are heavy steel and cast iron, which radiates heat.  They also have a convection or room blower to circulate the room air in from the back of the stove, across the top of the fire box to gain heat and out the front. This results in a a very warm room. 

 

   

                                                            

  A good example of this type of stove is the Englander 25-PFS. This stove has 2 - 140 CFM convection blowers mounted high on the back of the fire box to push as much room air as possible through the stove. The user controls are fairly simple. They include a rotary knob with 4 to 5 heat levels that release 1.0 to 5.0 lbs of pellets per hour into the burn pot depending on the setting. The controls also include a simple 2 to 3 speed rocker switch or rotary knob for setting the room blower speeds and an On/Off switch. Adjusting these controls is tricky and care must be taken in order to not overfire the stove. Overfiring occurs when the heat level is set high and the convection fan is not set high enough to keep the internal stove temperature down. This is one reason that there are safety devices to prevent a fire. Other safety measures use snap discs, vacuum switches and overload circuitry to prevent fires when the convection blower or combustion blower fails. These stoves are started by adding a handful of pellets into the burn pot and topped with starting gel, then lit with a match. These early units are not as efficient but still provide good heat without chopping and stacking a lot of wood. Also since wood pellets do not contain bark, they burn much more cleanly.


 Modern units now have many more features plus more efficient designs. Most newer designs unlike the early models, have an exhaust blower at the end of the combustion air path in the stove just before the hot air enters the pellet vent pipe. Since these combustion blowers pull in clean air and have hot air containing pellet ash traveling through them, they are more rugged and better sealed to prevent ash from being released and ruining their bearings. To be more efficient, the burn air comes in from the outside of the house using an OAK (Outside Air Kit). In this manner, warm room air is no longer wasted by sending it up the chimney. The design of the convection blower path for warming room air is much more efficient now. A convection blower anywhere from 165 CFM to 265 CFM is employed and mounted low in the back of stove. This creates a long path around the fire box and out the front through a heat exhanger mounted over the fire box consisting of tubes or accordian type plenum that Harman stoves employ. The user controls are much more sophisticated. They incorporate multi-layer circuit boards with LEDs to display the heat and fan settings. These boards also control the fan speeds in conjunction with the heat levels so overfiring cannot occur. The newer stoves have all needed safety devices that prevent overfiring due to part failure. These devices are bi-metal thermo switches called snap discs and either open or close at a designated temperature or a thermocouple connected to the control board. These safety devices stop the auger from feeding pellets which will put out the fire when an unsafe condition occurs. New features include larger hoppers that hold more pellets and larger ash pans to hold more ash. Top or bottom feed auger systems that deliver the pellets from the hopper to the burn pot have been improved to prevent auger jams.

 All pellet stoves have internal moving parts that can fail and may need replacement. The interior of the stove has 110 volt shock hazzards and very sensitive solid state parts that can short out easily so care and experience is needed. Always unplug the unit before replacing parts.

Below is a list of some parts and when they may need replacing:

Door and window gaskets get old, frayed then get brittle and break. If the flame gets lazy the door and window gaskets become leaky which causes poor heating performance.

Hopper gaskets get old, frayed then get brittle and break and let air in the hopper that can feed a hopper fire or back burn.

Ash pan gaskets get old, frayed then get brittle and break and let air in that can cause a lazy flame and poor heating performance

Ignitors wear out as it may take longer than 4-8 mins to light the pellets or on some startups, they may not light.

Auger motors get sluggish and also may skip which means the gears in the gear box are stripped.

Convection and Combustion blowers may become noisy, cease and not turn at all, or if the windings are bad the fan blades may need a push to get going.

Control boards or panels can get suffer damage from AC line surges and get flakey or intermittent. This can cause pellet overfeeding, the triacs can fail so the devices they control (Blowers, auger motor and ignitor) will stay on or not work at all. The power button may not be able to turn the stove on anymore.

Snap discs are temperature sensing bi-metal strips that open or close at the designed temperature so when they fail thet either stay open or remain closed.

Vacuum switches close when they sense firebox vacuum pressure or exhaust blower pressure and will not change state when pressure is applied.

Firebox door and hopper safety switches fail and stop the auger from turning which makes the fire go out.

Pellet Stove School is in Session

 

Pellet Stove School is in session and you can learn from the master. There is a certain amount of care the goes into maintaining a pellet stove, but it it's worth it. I don't just sell pellet stoves after all, I use one in my own home. I wouldn't sell something I wouldn't use myself. It heats my whole house and is much cheaper than oil.

 

Let me share my expertise. I love to talk pellet stoves. I just love it! I'll be your teacher and you'll get tips on parts replacing, how stoves work, news, and more!
