TROUBLESHOOTING QUICK REFERENCE

NO HOT WATER:

Insuffi cient Combustion Air or Venting
Issues – combustion chamber thermal
cut off tripped.

Follow the steps on pp 18 – 19. Always check
and clean the base ring fi lter and the fl ame
arrestor.

Pilot will not light

Check gas supply/Bleed air from gas line/turn
gas on.

Pilot will not remain lit when top gas
control knob is released

Test thermocouple and gas control valve/
thermostat as described on pp 20-21.

Burner will not light or remain lit.

Low gas pressure – check as described on p
18. Insuffi cient combustion air – follow steps
on pp 18 -19.

INSUFFICIENT HOT
WATER:

Water heater improperly sized to meet
hot water demands

Compare hot water requirements with the
capacity of the water heater. See sizing guide
on p. 25. You may also use the volume test
on page 34 to analyze your hot water needs.
If necessary, install a water heater with greater
capacity.

Gas Control Valve/Thermostat set
too low

Turn temperature dial to desired temperature
as described on p. 24

Sediment or lime in the tank

Drain (p. 17). Determine if water treatment is
needed (p. 29).

WATER LEAKAGE:

Condensation

Adjust the thermostat setting (p 24).

Dripping Temperature & Pressure Relief
Valve

Check water supply pressure.

In closed systems, the supply pressure should
not exceed 80 psi (in a 24 hour cycle). If the
pressure exceeds 80 psi, install a pressure
reducing valve in combination with a properly
sized thermal expansion tank (pp. 35-36 & 37).

IMPORTANT: Before performing any test, check the area around the water heater for any source of a flammable

vapor (i.e gasoline, paint thinners, etc.) If any sources are found do not proceed until they are removed.
