IMPORTANT
For all valves, the air MUST be purged from the gas line before the pilot will light properly. The time taken to do
this will depend on the length of gas line from the meter to the unit and the length of time since the unit or gas
line was last used (in the case of non-use during warm weather for example). It may take from 3-15 minutes
before all the air is purged and the pilot will light properly. This is done using the method for lighting the pilot,
but holding in the control valve for a longer period. Follow the LIGHTING INSTRUCTIONS in this manual for
your specifi c valve type.
PROBLEM CAUSE SOLUTION
1. Pilot will not light a. Obstruction in pilot gas supply/
pilot gas supply line is kinked
b. Inadequate gas supply
c. Pilot out of adjustment
d. Air in line
a. Clear out obstruction. Replace pilot gas
supply line if kinked.
b. Have gas pressure checked by installer or
gas supplier.
c. Adjust pilot (see page 5).
d. Air should clear, attempt to relight.
2. Pilot will not stay lit after
releasing knob
a. Pilot fl ame out of adjustment (tip
of fl ame should encircle tip of
thermocouple)
b. Thermocouple (SPK) either too
tight or too loose
c. Bad thermocouple
a. Adjust pilot (see page 5).
b. Thermocouple should be fi nger tight and
then

" turn with a wrench.
c. Replace thermocouple.
3. Log set extinguishes
a few minutes after
lighting
a. Inadequate gas supply causes
pilot fl ame to reduce after burner
lights
a. Using pilot adjustment, increase gas to
pilot. Pilot fl ame must be in contact with the
thermocouple tip.
4. Log set extinguishes
after burning for some
time (approximately 10
minutes to 1 hour)
a. Thermocouple has overheated;
glass doors are closed
b. Thermocouple has overheated;
insulation pad is not in place
c. Thermocouple has overheated;
burner fl ames are heating the
thermocouple cold junction
a. Be sure glass doors are open during
operation.
b. Be sure that the insulation pad is in place
between the burner pan and the pilot
bracket.
c. Be sure the pilot assembly and the fl ame
diverter are in their proper position. Rearrange
logs so that fl ame is not defl ected to the
thermocouple.
5. Pilot will light without
holding in knob or gas
fl ows to burner without
pilot being lit
a. Valve is installed backward a. Reinstall valve with inlet port attached to gas
supply and outlet port attached to burner.
