TEST SOLUTION
Inspect all wires, ensure good tight connections. Verify that all
wiring is installed exactly as specifi ed.
Inspect the wiring harness, and verify the harness is tightly con-
nected to the module. Verify that you have 7 wires and they are
connected in the right order.
Conduct the following test to verify if the problem is the module or
valve. To measure voltages, turn multimeter to "DC" place the red
lead from multimeter on the screw on the terminal block for the
wire you are checking, touch black lead to ground (valve body).
Importantly, a "Zero" volts reading does not automatically indicate
a bad module, there may be too little resistance in the valve so-
lenoid. Check if the Green wire is disconnected from the valve.
The voltage output from the module should be between 2 and
3 volts.
Check all seals.
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 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.
Realign door and secure.
Restrict vent exit with restrictor plate. See Restricting Vents.
Remove blockage. In really cold conditions, ice buildup may occur
on the terminal and should be removed as required.
Confi rm installation with venting parameters.
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.
