After use, cleaning of the pilot burner may be required for the 

proper flame. The pilot orifice can be cleaned with high pressure 

air or by placing under running water. Pilot orifice must be dry 

before replacement. Use a pipe cleaner to clean inside the pilot 

after the pilot orifice has been removed.
Removing Pilot Orifice

1. Disconnect the pilot supply line at the pilot burner

2. Remove pilot orifice from pilot burner. It may be necessary to 

tap on pilot burner in order to remove the pilot orifice.

Remove the burner and apply water pressure inside the throat of the 

burner and down into the ports; follow with air pressure.
Removing Main Burner

1. Remove casing front.

2. Disconnect pilot bracket from the burner.

3. Remove brass nut from burner.

4. Disconnect burner from chamber leg flange.

5. Remove burner from bottom of combustion chamber.

A qualified serviceman should remove the chamber and apply air 

pressure to the inside in order to clear all passageways.

1. A primary air adjustment bolt is located on left, front of burner throat. 

The bolt can be screwed into burner throat to REDUCE primary 

air or unscrewed from burner throat to INCREASE primary air.

unscrew  bolt  from  burner  throat.  Also,  refer  to  Step  2. 

To reduce resonation (whistling) noise or extinction (popping) 

noise, screw bolt into burner throat.

2. An  air  shutter  bracket  is  attached  to  top  of  burner  throat. 

The air shutter bracket lays flat across top of burner throat. 

If yellow flames can not be removed from main burner by 

using primary air adjustment bolt, the air shutter bracket can 

be pivoted upward to allow additional primary air to enter 

burner throat.

  a.  If using piezo ignitor, check electrode location.

  b.  Remove nut at orifice and check for gas.

  c.  If gas available, check for blocked orifice or pilot.

  a.  Proper size of pilot flame.

  b.  Defective or weak thermocouple.

  a.  Pilot flame not covering the thermocouple properly when 

knob is released.

  b.  Defective thermocouple.

  c.  Defective magnet in the safety section of valve.

  a.  Thermostat needs calibrating.

  b.  Defective thermostat section.

  a.  Tighten blower screws.

  b.  Check blower wheel in the open for balance.

  a.  Remove main burner to check for obstructions in throat, 

ports and orifices.

  b.  Install new main burner orifice and pilot orifice

  c.  Check gas valve for leaking.

  d.  Open the air bolt on the main burner in order to increase the 

amount of primary air.

  a.  Small yellow tip not objectionable.

  b.  Remove pilot orifice. Check and clean.

  a.  Improper venting of flue products. Relight and check for 

improper venting.

  b.  If  vented  properly,  check  vent  safety  switch,  replace  if 

defective.

  a.  Examine burner for defects.

  a.  Check fan control by shorting across terminals.

  b.  Check for blower wheel bind by removing wheel and operat-

ing motor.

  c.  Check for frozen bearings due to lack of oil.
