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.
b. To access the cleaning rods lift the hopper lid. Both
black bent handle pull rods are located close to the face
of the appliance to the left and right side.
c. To clean, pull the rods straight out until it stops,
approximately 20 inches (508mm). Slide the rods OUT
and IN a couple of times.
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 24
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.
Be sure the appliance is allowed to cool, has been
unplugged and the exhaust blower is off
b. Remove access door on the right of the appliance (4
screws).
c. Use a small vacuum hose attachment to clean area.
d. Re-install and close trap door.
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 or changing fuels
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.
a.
Be sure the appliance is allowed to cool, has been
unplugged and the exhaust blower is off.
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 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.
