PROBLEM
- turn on all gas appliances and see if pilot flame flutters, dimin-
ishes or extinguishes, especially when main burner ignites. Monitor
appliance supply working pressure.
- check if supply piping size is to code. Correct all undersized piping.
- 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
B A
test point. Check with burner operating on "HI". Gauge should read
7" (minimum 4.5") water column for natural gas or 13" (11" mini-
mum) water column for propane.
Outlet pressure can be checked the same as above using screw
(B). Check with burner operating on "HI". Gauge should read 3.5"
water column for natural gas or 10" water column for propane.
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. See air shutter open-
ings, page 13.
- check the input rate: check the manifold pressure and orifice size
as specified by the rating plate values.
- clean the glass with a recommended gas fireplace glass cleaner.
DO NOT CLEAN GLASS WHEN HOT.
If deposits are not cleaned off regularly, the glass may become
permanently marked.
- increase fresh air supply. (Use one of the methods described in
ANSI Z223.1 Section 5.3 or the applicable local code.)
- increase fresh air supply. (Use one of the methods described in
ANSI Z223.1 Section 5.3 or the applicable local code.)
- check CO output from catalytic tiles. See Maintenance Section.
Replace if necessary.
- check that the logs are correctly positioned.
- open air shutter to increase the primary air. See air shutter open-
ings, page 13.
- check the input rate: check the manifold pressure and orifice size
as specified by the rating plate values.
- reverse.
- replace.
- check for ground (short); repair ground or replace wire.
- replace.
