PROBLEM POSSIBLE CAUSE TEST / CORRECTIVE ACTION

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.
