5. Cleaning Heat Exchanger & Drop Tube
• Frequency: Monthly or every ton of fuel (50 bags).
• By: Homeowner
NOTE: Heavy duty vacuum cleaners may be obtained,
specifically designed for solid fuel appliance cleaning.
Tools Needed: A Shop Vacuum and generic micro cleaning
kit; flat head screwdriver; bottle brush, and a ½" ID hose.
a. It is necessary to remove the baffle to gain access to the
heat exchanger (Figure 21.2).
b. Vacuum the ash from the heat exchanger with an
upholstery brush to remove the majority of the ash. Be
sure to vacuum the back of the baffle also. Inspect the
drop tube and remove any residue build-up in the drop
tube (Figure 21.3).
c. Assemble the crevice tool from the micro cleaning kit to
attach to a Shop Vac (Figure 21.4).
d. Use the crevice tool to finish cleaning the heat exchanger
fins. It is critical that the 2 exhaust exits at the back of
the firebox floor (left and right) be thoroughly cleaned
(Figure 21.2). There are several ways this can be done:
— Use the crevice tool.
— Attach a hose 1/2 inch (12.7mm) inside diameter
and approximately 2 feet (607mm) in length to your
vacuum hose.
— Use a bottle brush and push the ash down to the
bottom. Remove the combustion (exhaust) blower
and then vacuum out the ash.
Hopper Fire Risk!
For trouble free use of your pellet appliance
you must perform cleaning as called for in
these instructions. Not doing so will result in:
• Poor operating performance
• Smoke spillage into the home
• Overheating of components
Not properly cleaning your appliance on a
regular basis will void your warranty.
NOTE: Shop Vacuum and Micro Cleaning Kit examples
are items that can be purchased at your local hardware
store.
