PROBLEM
- remove blockage. In really cold conditions, ice buildup may occur
on the terminal and should be removed as required.
- refer to Figure 13 to ensure correct location of storm collars.
- check pressure readings:
Inlet pressure can be checked by turning screw (A) counter-clock-
wise 2 or 3 turns and then placing pressure gauge tubing over the
test point. Gauge should read 7" (minimum 4.5") water column for
natural gas or 13" (11" minimum) water column for propane. Check

A
that main burner is operating on "HI".
Outlet pressure can be checked the same as above using screw (B).
Gauge should read 3.5" water column for natural gas or 10" water
column for propane. Check that main burner is operating on "HI".
AFTER TAKING PRESSURE READINGS, BE SURE TO TURN
SCREWS CLOCKWISE FIRMLY TO RESEAL. DO NOT
OVERTORQUE.
Leak test with a soap and water solution.
- ensure air shutter opening is free of lint or other obstructions.
- check that the logs are correctly positioned.
- open air shutter to increase the primary air.
- check the input rate: check the manifold pressure and orifice size
as specified by the rating plate values.
- check that the door gasketing is not broken or missing and that the
seal is tight.
- check that both 4" and 7" vent liners are free of holes and well
sealed at all joints.
- check that minimum rise per foor has been adhered to for any
horizontal venting.
- clean the glass with a gas fireplace glass cleaner. DO NOT CLEAN
GLASS WHEN HOT.
If deposits are not cleaned off regularly, the glass may become per-
manently marked.
- check door seal and relief flap seal.
- check for chimney blockage
- check that chimney is installed to building code.
- room is in negative pressure; increase fresh air supply.
- purge the gas line.
- fill the tank.
- turn up the pilot flame.
- gently twist the pilot head to improve the flame pattern around the
thermocouple.
- loosen and tighten thermocouple.
- clean thermocouple and valve connection.
- replace thermocouple.
- replace valve.
- replace.
