How this Pellet Heater Works
This pellet heater is a combination of four systems working together to burn pellets and transfer
the heat to your room. Your heater will only burn when there is an acceptable amount of air,
pellets, and heat present in the firepot. Air is supplied through the Combustion Air/Exhaust
System. Pellets are supplied through the Pellet Feed System. Heat comes from combustion and
is transferred to the room through the Convection Heat System. The last system is the Safety
System. If any one of these systems does not work right, your heater will not operate correctly.
When troubleshooting any problem with your stove, it is easiest to determine which system is
working incorrectly and then go through each component of that system until the problem is
found. The tables below lists the major components of each system and tips for troubleshooting
your heater (see the illustration below for each component's location and appearance).
Combustion Air/Exhaust System
Consists of: Purpose: Troubleshooting Tips
Air Inlet Provides air for combustion Aluminum duct not crushed or blocked
A IR C ONTROL Adjusts the amount of air going
to the firepot Slides in and out
Firepot Hold pellets during combustion Holder on correctly, no clinkers, no air leaks
Ash Traps Trap flyash Cleaned out and on correctly
Exhaust Blower Pull air through firepot and push
flue gases out flue Cleaned out
HINT: This system is the hardest to troubleshoot and crucial to the heater's
operation. It must be air-tight through the entire chain of
components. The most common problem is an air leak into the
firebox. This will rob air from the firepot, making combustion
incomplete (leading to more soot, more smoke, less heat, and over-
feeding).
