When Gas Pressure Is Too Low
• pilot will not stay lit
• burners will have delayed ignition

• propane/LP gas supply may be low (propane/LP only)
You may feel your gas pressure is too low. If so, contact your local
natural or propane/LP gas supplier.
SERVICE HINTS
1. Shut off the unit, including the pilot. Allow the unit to cool for
at least thirty minutes.
2. Inspect burners, pilot, and primary air inlet holes on injector
holder for dust and dirt (see Figure 33).
3. Blow air through the ports/slots and holes in the burners.
4. Check the injector holder located at the end of the burner tube again.
Remove any large particles of dust, dirt, lint, or pet hair with a soft
cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the injector holder.
6. In case any large clumps of dust have now been pushed into
the burner repeat steps 3 and 4.
Clean the pilot assembly also. A yellow tip on the pilot flame indicates
dust and dirt in the pilot assembly. There is a small pilot air inlet hole about
two inches from where the pilot flame comes out of the pilot assembly (see
Figure 34). With the unit off, lightly blow air through the air inlet hole.
You may blow through a drinking straw if compressed air is not available.
