TEST SOLUTION
-
Remove blockage. In really cold conditions, ice buildup
may occur on the terminal and should be removed as
required. To minimize this from happening again, it is
recommended that the vent lengths that pass through
unheated spaces (attics, garages, crawl spaces) be
wrapped with an insulated mylar sleeve. Prevent sleeve
from sagging. Contact your local authorized dealer for
more information.
-
Refer to "VENTING" section to ensure correct location of
storm collars.
-
Check pressure readings:
Inlet pressure can be checked by turning screw (A)
counter-clockwise 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"
(minimum 11") water column for propane. Check 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 OVER TORQUE.
Leak test with a soap and water solution.
-
Ensure air shutter opening is free of lint or other
obstructions.
-
Check that the burner media is correctly positioned.
-
Open air shutter to increase the primary air.
-
Check the input rate: check the manifold pressure and
orifi ce size as specifi ed by the rating plate values.
-
Check that the door gasketing is not broken or missing
and that the seal is tight.
-
Check that both vent liners are free of holes and well
sealed at all joints.
-
Check that minimum rise per foot has been adhered to
for any horizontal venting.
-
Clean the glass with a recommended gas fi replace glass
cleaner. DO NOT CLEAN GLASS WHEN HOT.
-
If deposits are not cleaned off regularly, the glass may
become permanently marked.
-
Ensure exhaust bracket gasket seal.

-
Room is in negative pressure; increase fresh air supply.
