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 reoccuring, the vent lengths that pass through unheated spaces
(attics, garages, crawl spaces) be wrapped with an insulated mylar
sleeve).
Refer to "venting" section to ensure correct installation.
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 as described on the chart below.
Check that main burner is operating on 'HI'. Outlet pressure can be
checked the same as above using screw (B). Gauge should read as
described on the chart below. Check that main burner is operating
on 'HI'. After taking pressure readings, be sure to turn screws
clockwise fi rmly to reseal. DO NOT OVER TORQUE.
Leak test with a soap and water solution.

Return air shutter to specifi ed opening, see "venturi adjustments"
section in the installation manual.
Ensure air shutter opening is free of lint or other obstructions.
Ensure the media is positioned correctly in the appliance.
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.
Ensure door gaskets are not broken or missing and the seal is tight.
Ensure vent liners are free of holes and well sealed at all joints.
Check that minimum rise per foot (meters) 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.
Check door seal.
Check for exhaust damage.
Check that venting is installed correctly.
Room is in negative pressure; increase fresh air supply.
test solution
Verify the thermocouple/sensor is clean and the wiring is undamaged.
Verify the interrupter block is not damaged or too tight. Verify
connections from pilot assembly are tight; also verify the connections
are not grounding out to any metal. (Remember, the fl ame carries the
rectifi cation current, not the gas. If fl ame lifts from pilot hood, the circuit
