Others 1
A) Heater undersized.
Reduce hot water use.
B) Low gas pressure. Contact dealer.
C) incoming water is unusually cold. Allow more time for heater to reheat.
D) Leaking hot water pipes or fixtures. Have plumber check and repair leaks.
PIPE TOO HOT
(ABOVE I70 F)
A) Not enough dilution air to mix with
flue gases.
Proper dilution air must be provided for dilution of flue
temp. Refer to “INSTALLATION INSTRUCTIONS”
section.
B) Dilution air too hot for mixing with
flue gases.
Check for heat sources around and/or blockage of
dilution air intake at draft hood (see page 28).
C) Wrong burner orifice. Install correct orifice.
YELLOW FLAME
A) Dirt in burner ports Turn off heater and gas, clean burner head.
B) Combustion air path restricted. Check dilution air intake, exhaust venting, and air
openings in bottom base pan for obstructions or
blockage.
C) Not enough dilution air. Check dilution air intake for obstructions or
blockage.

A) Water on the floor under heater. See “CONDENSATION” section.
B) Water dripping from blower assembly. Provide drip “JEE” to catch condensation from horizon­
tal section of exhaust vent dose to blower assembly.
WATER LEAKS
Improperly sealed, hot or cold supply
connections, relief valve, drain valve
or thermostat threads.
Tighten threaded connections.
Leakage from other appliances or water
lines.
Inspect other appliances near water heater.
Condensation of fiue products. See “CONDENSATION” section.

WATER HEATER SOUNDS
SIZZLING-RUMBLING
Condensation dripping on burner. See “CONDENSATION” section.
Sediment at bottom of heater tank. Clean sediment from tank. Refer to DRAINING
instruction in Maintenance section of manual.
SOOTING Improper combustion. Refer to COMBUSTION AIR AND VENTILATION
on pages 10, II, and 12.
