Pilot flame does not
stay lit.

Pilot (piezo-electric)
pushbutton igniter does
not light the pilot flame.

1. Check if igniter is generating a spark.

2. Check for loose spark wire or igniter nut.

3. Check position of electrode 3/16” from

pilot burner tip.

4.  Check for dirty/sooty electrode.

5.  Retry igniter.

1. Yes - Skip to test #3.

No - Proceed with test #2.

2. Yes - Tighten, skip to #5

No - Proceed with test #3

3. Yes - Skip to test #4.

No - Reposition electrode and
skip to test #5

4. Yes - Clean, skip to test #5

No - Proceed with test #5

5. Lights - Okay.

Doesn’t light - Replace igniter
mechanism.

1. Yes - Block or redirect the
    draft to keep the flame burning

steadily.  Skip to test #6.
No - Proceed with test #2.

2. Yes - Adjust the pilot valve

(part of gas control valve) to
increase the flame size, un
screw and retain the slotted
threaded cover; turn the pilot
valve adjustment screw two
turns counter clockwise; re-
install the threaded cover.  Skip
to test #6.
No - Proceed with test #3.

3. Yes - Clean. Skip to test #6.

5.  Increase if needed, proceed
     with test #6.

6. Stays lit - Okay.

Does not stay lit - Replace gas
control valve.

1. Observe if pilot flame is “wavering” (being

blown about by a draft).

2. Observe if pilot flame is too small to heat

thermocouple.

3. Check for dirty/sooty pilot burner.

4. Check thermocouple output voltage.

5. Check gas supply pressure with all other

equipment operating. (6” WC for natural
gas and 11” WC for propane, minimum)

6. Observe pilot flame.
