TROUBLE SHOOTING GUIDE

PROBLEM
- service or replace Oxygen Depletion Sensor System
- correct piping and/or regulator to provide correct pressure
- clean thermopile connection to the valve. Reconnect.
- replace Oxygen Depletion Sensor System / valve.
- shorten wire to correct length or wire gauge.
- replace.
- open window or door. (Use one of the methods described in ANSI
Z223.1 Section 5.3 or the applicable local code.)
- fill the tank.
- service or replace Oxygen Depletion Sensor System
- correct piping and / or regulator to provide correct pressure.
- purge the gas line. If a glass door has been installed, ensure that
the door is open or removed prior to purging.
- fill the tank.
- service or replace Oxygen Depletion Sensor System
- loosen and tighten thermocouple.
- clean thermocouple and valve connection.
- replace Oxygen Depletion Sensor System
- test and replace valve.
- replace.
- remove stoppage in orifice.
- replace.
- fill the tank.
- check if pilot can be lit by a match
- check that the wire is connected to the push button ignitor.
- check if the push button ignitor needs tightening.
- replace the wire if the wire insulation is broken or frayed.
- replace the electrode if the ceramic insulator is cracked or broken.
- replace the push button ignitor.
- check that the manual valve is turned on.
- check the pilot orifice for blockage.
- replace the valve / Oxygen Depletion Sensor System.
- call the gas distributor.
TEST SOLUTION
- connect a jumper wire across the wall switch terminals; if main
burner lights, replace switch / thermostat.
- disconnect wires from valve. Connect a jumper wire across termi-
nals 1 & 3; if the main burner lights, check the wires for defects and
/ or replace wires.
