6. Cleaning Heat Exchanger Chambers & Drop Tube
• Frequency: Monthly or every 1 ton of fuel
• By: Homeowner
The amount of ash buildup in the fire pot will be a good guide
to determine how often you should clean the heat exchang-
ers.
a. Allow the appliance to completely cool down before
pulling the cleaning rods. Turn the thermostat on and
then immediately off to start the exhaust blower on its
cycle time. It will pull fly ash out the exhaust instead
of into the room. Open the cast hinged face to access
the 2 cleaning rods.
b. Locate the 2 exposed rods directly underneath the heat
exchanger tubes. Figure 13.1.
c. To clean, pull the rods straight out until it stops,
approximately 8 inches (203mm). Slide the rods OUT
and IN a couple of times.
Figure 13.1
7. Cleaning Beneath Heat Exchanger
• Frequency: Monthly or after burning 1 ton of fuel
• By: Homeowner
a. Be sure the appliance is allowed to cool, has been
unplugged and the exhaust blower is off
b. A more thorough cleaning is needed to remove the
excess ash that is left behind from the use of the cleaning
rods for the heat exchanger tubes.
c. The ash will be resting on the back of the baffle. This will
require removing the cast baffle. Please refer to page 22
for a detailed explanation of removing the baffle.
8. Cleaning the Exhaust Path
• Frequency: Every 25 bags or monthly or more fre-
quently depending on ash build-up.
• By: Homeowner
a. Appliance must be completely cool.
b. Open cast hinge face. Remove baffle and right
brick and thoroughly vacuum the area and continue
throughout the rest of the firebox.
c. Replace right brick and baffle and close cast hinge
face.
9. Cleaning the Hopper
• Frequency: Monthly or after burning 50 bags of fuel
or when changing fuel type
• By: Homeowner
After burning approximately 1 ton of fuel you will need to
clean the hopper to prevent sawdust build-up.
A combination of sawdust and pellets on the auger reduces
the amount of fuel supply to the fire pot. This can result in
nuisance shutdowns and mis-starts.

the appliance to completely cool down.
b. Empty the hopper of any remaining pellets.
c. Vacuum the hopper and feed tube.
NOTE: Hearth & Home Technologies recommends to use a
heavy duty vacuum cleaners specifically designed
for solid fuel appliance cleaning.
10. Soot and Fly Ash: Formation & Need for Removal
in Exhaust Venting System.
• Frequency: Yearly or more frequently depending on
ash build-up.
• By: Qualified Service Technician/Homeowner
Be sure the appliance is allowed to cool, has been unplugged
and the exhaust blower is off.
The products of combustion will contain small particles of fly
ash. The fly ash will collect in the exhaust venting system
and restrict the flow of the flue gases.
At start-up if there is incomplete combustion, or if there is a
shutdown or incorrect operation of the appliance it will lead
to some soot formation. This will collect in the exhaust vent-
ing system.
The venting (chimney) system may need to be cleaned at
least once a year or more often depending upon the quality
of your fuel or if there is a lot of horizontal pipe sections. Ash
will build up more quickly in the horizontal sections.
11. Cleaning the Glass
• Frequency: When clear view of the fire pot becomes
obscure
• By: Homeowner
a. Appliance must be completely cool before cleaning
glass.
b. Vacuum fly ash from glass and door rope.
c. Use a damp paper towel or any non-abrasive glass
cleaner. Wipe off with dry towel.
