How To

Routine Cleaning & Maintenance For Enviro Pellet Stoves

The following list of components should be inspected and maintained routinely to ensure that the appliance is operating at its optimum and giving you excellent heat value:

2-3 Days/Weekly

Semi-annually or 2 Tons of fuel

Burn Pot and Liner

Exhaust Vent

Ash Pan

Fresh air intake Tube

Inside Firebox

Blower Mechanisms

Door Glass

Heat exchanger tubes

Heat exchanger tubes

Behind firebox liners

Ash pan and Door gaskets

All Hinges

Door Latch

Post Season Clean-up


  • Torx T-20 Screwdriver
  • Brush
  • Soft Cloth
  • 5/16” Wrench or Socket
  • Vacuum with fine filter bag

Cleaning of the burn pot and liner must only be done when stove is cold.  To remove the burn pot and Burn pot liner, open the door using the door handle provided (located on the right–hand side of the stove) Swing the door open. Lift the liner from the burn pot.  Lift the burn pot from the firebox by gently lifting up the front of the burn pot, then sliding the assembly from the air intake tube and the ignitor cartridge.

This is the pot where the pellets are burned. Every two (2) to three (3) days (when the unit is cold), remove the burn-pot liner from the stove and inspect it to ensure proper air flow through the liner. Failure to keep the liner clean may cause a build up of fuel past the burn pot liner and up the drop tube.  This will cause the auger to jam and may result in pellets burning in the drop tube and hopper.  Using a metal scrapper, remove material that has accumulated or is clogging the burn-pot  back  liner holes.  Then dispose of the scrapped ashes from the liner and from inside the burn-pot. Place the burn-pot back into the stove, making sure that the pipes are properly inserted into the burn pot.  Place the liner back into the burn-pot, making sure that the ignitor hole in the liner is aligned with the ignitor tube. Pushing  the liner up against the ignitor tube.

If after long periods of burning, the fire continually builds up and overflows the burn pot or there is a build up of clinkers, this is an indication that the pellet fuel quality is poor or the stove may need cleaning. Check the stove for ash build up (clean if required) and adjust the slider / damper to produce the proper clean combustion.

Cleaning of the glass must only be done when the stove is cold.  Open the door by lifting the handle.  The glass can be cleaned by wiping down the outside and inside of the glass with a dry soft cloth.

If the glass has build up that can not be removed with only the cloth, clean the glass using paper towel and a gas appliance glass cleaner, this may be purchased through most dealers.  If a gas appliance glass cleaner is not available, use a damp paper towel dipped in fly ash to clean the glass.

After the glass has been cleaned use the dry soft cloth to wipe down the outside and inside of the glass.

Check the door latch every time the door is opened or closed to insure proper movement.

After extended use the gasketing may come loose.  To repair this, glue the gasketing on using high temperature fiberglass gasket glue available from your local ENVIRO dealer.  This is important to maintain an airtight assembly.

ASH PAN (weekly)
The ash pan is located under the burner.  Dump the ashes  into a metal container stored away from combustibles.  Monitor the ash level every week. Remember that different pellets fuels will have different ash content.  Ash content is a good indication of fuel efficiency and quality.

Freestanding: To remove the ash pan, simply turn the knob and pull out towards the front. Insert: To remove the ash pan open the door, remove the burn pot liner and the burn pot, then pull the ash pan out.


Open the door and the rod is located under the unit top, in the center of the stove just behind the door. This handle is to be pushed in and out a few times (only when the unit is cold) in order to clean away any fly ash that may have collected on the heat exchanger tubes.  As different types of pellets produce different amounts of ash, cleaning of the tubes should be done on a regular basis to enable the unit to run efficiently.

Inspect periodically to be sure that it is not clogged with any foreign material.

EXHAUST VENT (season) This vent should be cleaned every year or after two (2) tons of pellets.  We recommend contacting your dealer for professional cleaning.  To clean the vent pipe, tap lightly on the pipe to dislodge any loose ash.  Open the bottom of the “T” to dump the ash, then vacuum as much of the ash out of the vent pipe as possible.

Unplug the stove then open the right and left panels to access the two blowers.  Vacuum all dust from motors.  DO NOT lubricate the motors.  Check gaskets and replace if needed.

ALL HINGES (season)
Check all the hinges on the unit to ensure proper movement.

Removal of the firebox backing for bi-annual cleaning
Open the door by lifting the handle, remove the burn pot and burn pot liner.  Lubricate all screws with penetrating oil.  Remove the four (4) screws that hold the brick liner retainers in place.  Remove side brick liners by sliding them forward then out.  Pull the center panel out.  Vacuum and clean thoroughly.

Installation of firebox backing:
Insert center panel with backing. Place the two(2) sside panels back into the firebox and reinstall the two(2) retainers using two (2) screws in each side.  Replace the burn pot and burn pot liner. Close the glass door and secure.

Once you are finished using the pellet appliance for the season, unplug the stove for added electrical protection.  It is very important that the stove be cleaned and serviced as stated above.

Painted surfaces should be wiped with a damp cloth periodically. It is important to note that fingerprints and other marks can leave a permanent stain on plated finishes. To avoid this, give the surface a quick wipe with denatured alcohol on a soft cloth BEFORE lighting the fireplace.  Never clean surface when they are hot. Do not use other cleaners or abrasives as they may leave a residue or scratches, which can become permanently etched into the surface.

The paint on the steel firebox panels may peel.  This is due to extreme conditions applied to the paint and is no way covered by warranty.

It is recommended that your ENVIRO dealer replace the glass if broken.
The door glass is made of high temperature PYRO CERAMIC 5 mm thick.  The center panel is 15.4” x 9>0” (39.0 cm x 22.9 cm) and side panels are 2.6 x 9.0 inches (6.7 cm x 22.9 cm). They must be replaced with (Part# EF-062). Substitute materials will not be permitted.
