Why is the gas not flowing to the fire bowl?
1. Ensure gas supply shutoff valves are
open.
Ensure that main gas shutoff installed adjacent to heater is open. Ensure that knob
on gas valve inside unit is in on position. If OK, proceed to step 2.
2. Check for low gas supply pressure.
Ensure inlet gas supply pressure exceeds minimum valve indicated on rating plate. If
OK, proceed to step 3.
3. Check for faulty flame sense wiring or
connection.
Inspect flame sense wiring. Ensure wire harness terminals are securely fastened to
flame sense and to control module. If OK, proceed to step 4.
4. Check for faulty gas valve wiring or
connection.
Inspect gas valve wiring. Ensure wire harness terminals are securely fastened to
spade terminals on gas valve. If OK, proceed to step 5.
5. Check for gas valve failure or gas
valve relay failure
1. Measure voltage across gas valve during trial for ignition. If 24 vac is present and
gas valve does not open, gas valve is defective. Replace gas valve.
2. If 24 vac is not present, gas valve relay on control module is defective. Replace
control module.
