SYMPTOM

POSSIBLE CAUSES

CORRECTIVE ACTION

Flame too large

1.  Defective operator section of gas valve.

1.  Replace complete valve.

2.  Burner orifice too large.

2.  Check with local gas company for proper

orifice size and replace.

3.  If installed above 2,000 ft.

3.  Refer to orifice chart on Page 9.

Noisy Flame

1.  Noisy pilot.

1.  Reduce pilot gas with adjusting screw on combination
     gas control valve.

2.  Burr in orifice (if it whistles or resonates).

2.  Remove burr or replace orifice (do not enlarge orifices).

3.  Excessive gas input.

3.  See “Flame Too Large” above.

3.  Linted up mixer opening.

3.  Check for dust or lint at air mixer opening.

Floating Flame

1.  Blocked venting.

1.  Clean flue passageways to remove blockage.

Gas Odor

1.  Gas leak.

1.  Shut off gas service immediately.  Check piping.
      Call gas company.  See “For Your Safety”, Page 1.

2.  Chimney or flue obstruction.

2.  Clean flue.

3.  Drafts around appliance.

3.  Eliminate drafts.

Delayed Ignition

1.  Pilot flame too small.

1.  Check pilot orifice.  Increase pilot gas flow if
      necessary by adjusting inlet pressure from gas
      source (meter if natural gas or second stage
      regulator if propane - maximum 7” w.c. for
      Natural and 11” w.c. for propane).

2.  Burner ports clogged near pilot.

2.  Clean burner ports (do not enlarge ports).

3.  Low gas pressure.

3.  Check gas supply inlet pressure.  Check gas outlet
      (manifold) pressure for “minimum step” pressure
      (for “step” pressure chart see “Operation”).

4.  Pilot decreases in size when main

     inlet pressure.

5.  Drafts around appliance.

5.  Eliminate drafts.

6.  Bad venting.

6.  See “Venting”.

Failure to Ignite

1.  Main gas off.

1.  Open all manual gas valves.

2.  Defective gas valve.

2.  Replace gas valve.

Condensation of

1.  Improper venting.

1.  See “Venting”.

      pressure must not exceed 1/2 psi or

      supplying the gas.

      14” w.c.

Incorrect Gas Input

1.  Gas input not checked.

1.  Re-check gas input.

2.  Clogged orifice.

2.  Check orifice for clogging.  If clogged, clean out
      the hole carefully with a smooth wood toothpick.
      (Do not in any way enlarge or distort it).

Not enough heat

1.  Appliance undersized.

1.  This is especially true when a dwelling or room is
      enlarged.  Have the heat loss calculated and compare
      to the appliance output (approx. 70% of input).
      Your gas company or installer can supply you with
     this information.  If appliance is undersized, replace
      with correct size unit.

2.  Incorrect supply pressure.

2.  Check supply pressure as outlined above.

Too much heat

1.  Combination control valve sticks open.

1.  Replace combination control valve.

TROUBLE SHOOTING CHART - PILOT AND VALVE

1.  Gas valve not turned on.

1.  Turn gas valve to “on” position”.

2.  No voltage to valve.

2.  Check for 24 Volts to Valve.

3.  Defective thermostat.

3.  Check wall thermostat.

4.  No 115 Volt Line Voltage.

4.  Jump fan switch to check for voltage (fan will
      come on).

5.  Auxiliary limit switch open.

5.  Push on red buton to close.

6.  Blocked flue switch open.

6.  Push red button in to close.
