12. 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
venting 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 are any horizontal pipe sections.
Ash will build up more quickly in the horizontal sections
and elbows.

D. High Ash Fuel Content Maintenance
• Frequency: As needed
• By: Homeowner
Poor quality pellet fuel, lack of maintenance, or if the small
dial control is set to a less than optimum setting, poor
combustion conditions that make the firepot fill quickly with
ashes and clinkers.
This condition makes the appliance susceptible to
overfilling the firepot with pellets which may result in
smoking, sooting and possible hopper fires. The figure
below shows an example where the firepot overfills, pellets
back up into the feed tube and ash has accumulated in
the firebox.
An inefficient and non-economical method of burning of fuel
caused by poor quality pellet fuel is shown below.
If the ash buildup exceeds the half way point in the firepot
IMMEDIATE ATTENTION AND CLEANING IS REQUIRED.
