When ignitor button is pressed, there is spark at ODS/pilot but no ignition

1.Gas supply turned off or equipment shutoff valve closed

2.Control knob not in PILOT position

3.Control knob not pressed in while in PILOT position

4.Air in gas lines when installed

5.Depleted gas supply (propane/LP only)

6.ODS/pilot is clogged

7.Gas regulator setting is not correct

1.Turn on gas supply or open equipment shutoff valve

2.Turn control knob to PILOT position

3.Press in control knob while in PILOT position

4.Continue holding down control knob. Repeat igniting operation until air is removed

control knob is released

2.

Control knob not pressed in long enough

 

3.

Equipment shutoff valve not fully open

which allows thermocouple to cool,

 

 

causing pilot flame to go out. This

 

 

problem could be caused by one or both

 

 

of the following:

 

 

A) Low gas pressure

 

 

B) Dirty or partially clogged ODS/pilot

 

5.
