TROUBLESHOOTING

Problem

Possible Cause

Corrective Action

When  ignitor  button  is 

pressed  in,  there  is  no 

spark at ODS/pilot.

1. Ignitor  electrode  is  posi-

tioned  wrong.  Ignitor  elec-

trode is broken.

2. Ignitor electrode is not con-

nected to ignitor cable.

3. Ignitor  cable  is  pinched  or 

wet.

4  Broken ignitor cable.

5. Bad piezo ignitor.

6. Low battery.

1. Replace electrode.

2. Replace ignitor cable.

3. Free ignitor cable if pinched 

by any metal or tubing. Keep 

ignitor cable dry.

4. Replace ignitor cable.

5. Replace piezo ignitor.

6. Replace battery.

When  ignitor  button  is 

pressed  in  there  is  a 

spark  at  ODS/pilot  but 

no ignition.

1. Gas  supply  is  turned  off  or 

equipment  shutoff  valve  is 

closed.

2. Control  knob  not  fully 

pressed  in  while  pressing 

ignitor button.

3. Air  in  gas  lines  when  in-

stalled.

4. ODS/pilot is clogged.

5. 

Incorrect inlet gas pressure or in-

let regulator setting is damaged.

6. Control  knob  not  in  PILOT 

position.

7. Depleted  gas  supply  (pro-

pane).

1. Turn on gas supply or open 

equipment shutoff valve.

2. Fully  press  in  control  knob 

while pressing ignitor button.

3. Continue holding down con-

trol knob. Repeat igniting op-

eration until air is removed.

4. 

Clean  ODS/pilot  (see 

Care 

and Maintenance

, page 22) or 

replace ODS/pilot assembly.

5. Check inlet gas pressure or 

replace inlet gas regulator.

6. Turn control knob to PILOT 

position.

7. Contact  local  propane/LP 

gas company.

Only a qualified installer should bypass the 

pressure switch.

 Remove front panel of heater 

(see page 10). Locate the gas regulator. To by-

pass the pressure switch locate the set screw 

on the regulator. Use a small flat bladed screw 

driver to turn the set screw counterclockwise 

2 turns. This will bypass the pressure switch 

function.
The entire gas delivery piping including con-

nections  inside  the  heater  should  be  leak 

tested  by  the  qualified  installer. After  leak 

testing the qualified installer should light the 

appliance. Refer to the correct flame pattern 

as illustrated on page 21. All flame patterns 

should be safely inside the product. If for any 

reason they are not, stop use of the appliance 

and call for repairs.
