Alcove Installation Requirements
When the pellet stove is placed in a location where the ceiling height is less than 7' tall, it is considered
an alcove installation. Because of the reduced height, the requirements listed below must be met.
•
Minimum height is 60"
•
Minimum width is 46"
•
Maximum depth is 48"
•
Minimum clearance of 9" on each side and 3" on back
Restrictor Adjustment (qualified installers only)
In rare cases the vent will produce too much draft for the stove, leading to an inefficient burn, and in
some cases, the flame going out. The factory setting is wide open.
When to Adjust Restrictor(s):
Run the heater with the restrictors open (factory setting). If the fire goes out on low, or if un-burned
pellets are expelled from the firepot often (make sure they are un-burned, not just cylindrical embers),
the restrictor(s) will require adjustment. Follow the directions below.
Adjusting the Restrictor(s)
The intake restrictor acts as a fine
adjustment to the airflow where
the exhaust restrictor acts as a
coarse adjustment. To adjust the
restrictor(s), first close the intake
restrictor and assess heater
performance over time. If the
problem is not solved, open the
intake restrictor and adjust the
exhaust restrictor following the
directions listed under "Exhaust
Restrictor Adjustment".
Use these index marks to gauge restrictor
movement. Push in for more restriction
(pull out for less restriction).

NOTE: you will not notice much change
in the flame after adjusting the
restrictor. Check stove performance
over a long period of time.
Exhaust Restrictor Adjustment (qualified installers only)
a) Start the heater and allow it to get up to temperature. Set it to low burn.
b) Rotate the restrictor bolt until the indicator tab is at position # 1 (to the left)
c) Inspect the flame - if it is in-active and the spent pellets do not jump out of the burnpot, turn the restrictor bolt
so the indicator tab is at position # 3. Repeat this process until the flame is active and the spent pellets jump
out of the burn pot. Also verify the heater burns correctly on high.
