7. Cleaning Heat Exchanger Chambers & Drop Tube
• Frequency:
Monthly or every 1 ton of fuel
• By:
Homeowner
The amount of ash buildup in the firepot will be a good
guide to determine how often you should clean the heat
exchangers.
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.
Figure 31.1.
b. Locate the 2 rods directly underneath the heat
exchanger tubes. Rods are bent at a 90° angle for
easy handling.
c. To clean, pull the rods straight out until it stops,
approximately 5-1/2 inches (140mm). Slide the rods
OUT and IN a couple of times.
WARNING
Heat exchanger cleaning rods may be warm
to the touch. For safety purposes wear
gloves.
Do not pull heat exchanger cleaning rods
while appliance is operating.
Push cleaning rods IN when done, DO NOT
leave cleaning rods OUT. Injury can occur.

9. 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 35
for a detailed explanation of
removing the baffle.
NOTE:
There are 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.
