Technician’s Full Annual Cleaning Guide –AUSTROFLAMM Integra Free Standing & Insert Models

Caution: Turn off the stove and allow to cool. Once the stove has properly shut down and cooled,

unplug it before performing any cleaning or service.

Caution: Use only a certified ash vacuum to clean the stove. Using a regular home or shop vacuum

can result in a fire.

Caution: People with breathing problems should be careful to not inhale ash or dust during the

stove cleaning process. Use of a dust mask is recommended.

Caution: Even after allowing the stove to cool, hot embers may still be present in the firebox. Use

caution when you open the door and during the cleaning process. Use care, any remaining embers

can ignite clothing or objects close to the stove.

Caution: This cleaning guide is intended for Technician use only.

To maintain proper operation of any pellet stove, it is important to regularly clean the unit. Failure

to perform regular cleaning could lead to decreased performance, increased fuel consumption,

and an increased chance of a component failure. Component failures caused by lack of proper

cleaning are not covered under warranty.

This guide explains the recommended annual full service cleaning process. This process should

be performed no less than one time per year. More frequent full service cleanings may be

required depending upon the quality and quantity of fuel burned, vent configuration or in-home

Door, Burn Pot and Ash Pan

Spread a drop cloth or other suitable cover on the floor in front of and around the stove to

protect ash and debris from staining floors.

Open the door and vacuum out as much debris from the burn pot as possible. Clean the

door glass by wiping it with a dry paper towel or a dry, wadded up piece of newspaper. If

this fails, use any standard glass cleaner designed for use with wood stoves.

Clean out any remaining debris from the burn pot by lifting it out,

figure 1 figure 2

tipping it upside down, and tapping it on the ash pan (figure 1). If needed, use your flat-tip screwdriver to scrape away and loosen any remaining debris. Continue this process until all remaining ash debris is removed and all of the air holes in the burn pot are clear. Vacuum out the ash pan. Remove the ash pan and set it aside with the burn pot. (figure 2) Vacuum the area underneath where the burn pot sits. Using your brush and vacuum, clean the cast iron and gasket areas around the inside perimeter of the door.

Cast Iron Wall Plates

The back wall of the combustion area is made up of two cast iron plates that protect the heat

exchanger system from direct flame. If the area behind the cast iron plates is not periodically

cleaned, a complete blockage of the air paths can result. Sufficient blockage will cause the stove

to perform poorly and could result in a shut down .

Using a 6mm hex key wrench, remove the three screws securing the lower cast iron plate.

Once the screws are removed, the plate should pull away from the back of the stove.

Carefully lift the lower plate out and brush off any ash build-up from the front and back of

the plate.

Examine the lower plate’s gasket material for defect. Minor blemishes on the gasket are

acceptable, but replace the gasket if it’s broken or if pieces are missing. When finished,

set the plate aside.

Using the same 6mm hex key wrench, remove the two screws securing the upper cast iron

plate. It’s important to support the upper plate while the screws are being removed since

this plate is heavy and will fall if not supported.

Carefully lift the upper plate out and brush off any ash build-up from the front and back of

the plate. When finished, set the plate aside.

Heat Exchanger Area and Baffle Tubes

When you remove the two cast iron plates from the back of the combustion chamber, the entire heat exchanger system is exposed. You will be able to see the exchanger tubes as well as the scrapers that activate when the exchanger cleaning rods are pulled on the top of the stove. Vacuum the ash from the heat exchanger area, especially the area between the exchanger tubes. The soft brush and flat-tip screwdriver can be used to clean around and between the tubes. Clean out as much ash as possible (figure 3).

Figure 3 Figure 4

Carefully brush and clean the uppermost interior of the burn area.

Carefully brush and clean the grooves on the inside top of the fire box.

Do a final vacuum of the entire combustion area to remove any additional ash or debris.

Exhaust Manifold

For free standing models, remove the right and left side panels.. For insert models, pull the stove forward far enough to allow sufficient room to work comfortably. Remove the round exhaust manifold access plate by turning the thumb screw (figure 4). This may be a rectangular plate with four screws.

Thoroughly vacuum out all ash build-up as deep into the exhaust manifold as possible.

A long scraper contoured to fit the shape of the interior of the exhaust manifold wall was provided

with the stove. Use this scraper, to reach in and scrape out additional ash from the sides and

corners of the manifold.

Primary Air Passages

There are four air passages between the front of the exchanger area and the exhaust manifold.

These passages are the primary pathway from the combustion chamber to the combustion fan

and ventilation. If the passages become blocked, the stove will not burn efficiently and will exhibit

frequent errors and possible shutdown.

The passages are at the base of the exchanger area BEHIND the baffles. The passages are

rectangle shaped and are approximately 1” high by 2.5” wide. There are two on each side of the


The passages can be best seen by placing a flashlight inside the exhaust manifold (from the back

side of the stove) and then looking into the heat exchange / baffle tube area from the front of the

stove (while the lower cast wall is still removed). The holes should be clearly visible. If they are

not, this indicates a complete blockage.

Thoroughly clean these passages by passing a narrow, flat-tip screwdriver between the baffles or

by using the hooked end of the contoured scraper.

Combustion Motor

Using an 8mm socket, remove the four screws mounting the combustion motor to its housing (Figure 5). Examine and clean the motor, the housing, and the fan blades.

Note: Be careful not to bend or damage the fan blades.

Note: Use care to prevent damage to the combustion fan gasket. If the gasket does become

damaged during removal of the fan, the gasket will have to be replaced.

Note: Although not the most preferred method, if the combustion motor gasket does require

replacement but no gasket is available, a thin bead of hi-temp silicone can be used in place of the

gasket. Be careful not to apply too much silicone to the extent that it bleeds over and into the

actual exhaust pathway as this could potentially cause premature buildup of soot and interfere

with combustion fan operation.

Low Limit Switch

Carefully clean the low limit switch by reaching inside of the combustion fan housing with a damp

cloth and wiping off the flat surface of the switch. The switch can also be removed for easier

cleaning, but this would then require that the low-limit gasket be replaced upon reinstallation.

Convection Motor

Remove the two power leads from the motor, remove the four screws

mounting the convection fan to the stove (two screws on either side of the stove).

Remove the fan by pulling the motor out of the left side of the stove.

Note: The convection fan may appear to be stuck in place due to expanding and contracting

during normal use. A few very light taps on the right side metal housing of the fan should dislodge


Note: There should be a thin piece of gasket material between the fastening sides of the fan

housing and the stove body. Be careful to save this material when you re-install the fan. If the fan

appears to vibrate after reassembly, this gasket material may have become dislodged and would

simply need to be placed back into position.

Air Sensor

On the right side of the stove, remove the two screws mounting the air sensor. Carefully remove

the sensor by pulling up and away from the air intake tube. Once removed, examine the probes

that extend into the air intake tube for debris or residue. Clean with a soft brush or cloth.

Note: If the residue will not come off with a soft brush or cloth, use an aerosol circuit board



Remove the pellets from the Hopper. Using an 8mm socket, remove the six screws from the

auger shaft cover plate and pull out the plate.

Using a flat-tip screwdriver, scrape out any embedded pellet fines / dust residue from the auger


Note: To ensure an adequate air seal upon reinstallation of the cover plate, clean away all of the

old gasket / silicone material from the hopper surface and the cover plate. Upon re-installation,

re-seal the plate by using a thin bead of high-temp silicone around the edges of the plate. Be

careful not to apply too much silicone to the extent that it bleeds over and into the actual auger

pathway as this could potentially cause a blockage in the shaft.


Reassemble in reverse order. While doing so, follow all cautions and guidelines in this document,

especially as they relate to any gasketting notes. Failure to sufficiently adhere or correctly

re-gasket any specific gasket point can result in an air leak, poor combustion, repetitive stove

error or shutdown, and possibly a house fire.
