1.  Spark electrode does not produce spark.

a.  Spark electrode broken - replace.

c.  Ignitor wire damaged - replace.

d.  Piezo ignitor defective - replace.

2.  Spark electrode produces spark but pilot does not light.

a.  No gas to heater - turn on gas.

b.  PILOT position not properly aligned - turn gas control knob to 

PILOT position and depress.

c.  Pilot is blocked from spider web or dirt - clean pilot, see Page 

15.

3.  Pilot flame does not stay "ON" when control knob is released.

a.  Control knob in PILOT position not completely depressed or held 

in long enough.

b.  Thermocouple  not  tightened  into  gas  control  -  tighten 

thermocouple.

c.  Pilot flame not surrounding thermocouple - clean pilot, see Page 

15. 

d.  Inlet gas pressure too low, contact gas supplier.

e.  Thermocouple defective - replace.

f.  Gas control defective - replace.

4.  Main burner does not ignite.

a.  Main burner orifice is blocked - clean, see "Main Burner Flame 

Characteristics," Page 14. Attention: The number stamped on the 

main burner orifice is a millimeter diameter.

b.  Inlet gas pressure too low, contact gas supplier.

5.  Heater keeps shutting "OFF" during normal operation.

a.  Pilot is blocked - clean pilot, see Page 15.

b.  Inlet gas pressure too low, contact gas supplier

Attention: The thermocouple CAN NOT be replaced as an individual item. 

You must order a new pilot when replacing thermocouple.
  1. Turn OFF gas supply to the heater.

  2. Turn OFF electrical supply to the heater if optional blower is installed 

in heater.

  3. Remove lower louver from casing assembly (2 screws).

  4. Remove reflector from casing assembly (2 screws).

  5. Disconnect pilot tubing from pilot (see Figure 18, Page 15). Grasp nut 

A with a wrench when removing nut B with a second wrench.

  6. Remove pilot from pilot bracket (2 screws).

  7. Remove thermocouple lead from gas valve. 

  8. As parts are being replaced in reverse order, check for gas leaks at all gas 

connections before lower louver is replaced onto casing assembly.

  1. Turn OFF gas supply to the heater.

  2. Turn OFF electrical supply to the heater if optional blower is installed 

in heater.

  3. Remove lower louver from casing assembly (2 screws).

  4. Remove reflector from casing assembly (2 screws).

  5. Remove pilot bracket from main burner assembly (2 screws).

  6. Pivot pilot bracket with attached pilot away from main burner assembly 

(do not damage pilot tubing).

  7. Disconnect supply tubing from orifice holder(s).

  8. Remove orifice holder from venturi of main burner assembly (1 screw 

for each orifice holder).

  9. Remove main burner orifice from orifice holder. Attention: The number 

stamped on the main burner orifice is a millimeter diameter.

 10. As parts are being replaced in reverse order, check for gas leaks at all gas 

connections before lower louver is replaced onto casing assembly.

  1. Turn OFF gas supply to the heater.

  2. Turn OFF electrical supply to the heater if optional blower is installed 

in heater. 

  3. Remove lower louver from casing assembly (2 screws).

  4. Remove reflector from casing assembly (2 screws).

  5. Disconnect  inlet  supply  tubing,  outlet  supply  tubing,  pilot  supply 

tubing and thermocouple lead from manual gas control.

  6. If heater is attached to wall, disconnect gas supply line from inlet 

regulator.

  7. Remove heater from wall.

  8. Remove cotter pin from manual gas control rod.

  9. Remove manual gas control bracket from casing assembly (3 screws 

to be removed are located on casing assembly back).

 10. Loosen nut that secures manual gas control to bracket. Remove manual 

gas control from bracket. 

 11. As parts are being replaced in reverse order, check for gas leaks at all 

gas connections before reflector and lower louver are replaced onto 

casing assembly.

  1. Turn OFF gas supply to the heater.

  2. Turn OFF electrical supply to the heater if optional blower is installed 

in heater. 

  3. Remove lower louver from casing assembly (2 screws).

  4. Remove reflector from casing assembly (2 screws).

  5. Disconnect supply tubing from orifice holder(s).

  6. Remove pilot bracket from main burner assembly (2 screws).

  7. Remove main burner assembly from casing assembly (4 screws).

  8. Remove orifice shield from main burner assembly. Attach orifice shield 

to new main burner assembly.

  9. As parts are being replaced in reverse order, check for gas leaks at all gas 

connections before lower louver is replaced onto casing assembly.

Depressing the ignitor button completely causes a spark to occur at the 

pilot. 
To light the pilot, it is important that the electrode be 1/8" (3mm) from 

the  pilot.  The  spark  must  occur  at  the  point  the  pilot  flame  hits  the 

thermocouple. 
On a new installation with air in the gas line, it is suggested that a match 

be used. The match will light the pilot faster than the piezo under this 

condition.
