- Verify all connections. Verify the connections from the pilot
assembly are tight; also verify these connection are not
grounding out to any metal.
- Verify the fl ame is engulfi ng the sensor rod. This will increase
the fl ame rectifi cation. Verify correct pilot orifi ce is installed
and inlet gas specifi cations to manual. (Remember, the fl ame
carries the rectifi cation current, not the gas. If the fl ame lifts
from the pilot hood, the circuit is broken. A wrong orifi ce or
too high of an inlet pressure can cause the pilot to lift). The
sensor rod may need cleaning.
- Verify that the wire harness is fi rmly connected to the module.
verify that the ceramic insulator around the sensor rod is not
cracked, damaged, or loose. Verify the connection from the
sensor rod to the sensor wire.
- Clean sensor rod with an emery cloth to remove any
contamination that may have accumulated on the sensor rod.
Verify continuity with multimeter with ohms set at the lowest
range. Check for shorted wire or cracked insulator.
- Using a piece of sandpaper or emery cloth, remove the paint
from the pilot hood, ignitor and fl ame sensor.
- Inspect all wires, ensure good tight connections. Verify that all
wiring is installed exactly as specifi ed.
- Inspect the wiring harness, and verify the harness is tightly
connected to the module.
- Verify that all wires are connected in the right order. See
"wiring diagram" section.
- Using a piece of sandpaper or emery cloth, remove the paint
from the pilot hood, ignitor and fl ame sensor.
- Check for chimney blockage.
- Check that chimney is installed to building code.
- Room is in negative pressure; increase fresh air supply.
- Check damper positioning.
