smelled in room,
headaches.
White / grey fi lm
forms.
Flames are very ag-

PROBLEM
Short or loose
connection in sensor rod.
Poor fl ame rectifi cation
or contaminated
sensor rod.
Poor grounding between
pilot assembly and
gas valve.
Damaged pilot or dirty
sensor rod.
Wiring / Connection.
Wiring harness.
Appliance is spilling.
Sulphur from fuel is being depos-
ited on glass, logs or combus-
tion chamber
surfaces.
Door is ajar.
Venting action is too great.
Blockage in vent.
Compromised venting.
Vent recirculation.
TEST SOLUTION
- Verify all connections. Verify the connections from the pilot
assembly are tight; also verify these connections 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 pilot hood, the circuit is broken. A wrong orifi ce or to
high of an inlet pressure can cause the pilot fl ame to lift.) The
sensor rod may need cleaning.
- Verify that the wire harness is fi rmly connected to 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 a fi ne emery cloth or synthetic
scrub pad to remove any contamination that may have
accumulated on the sensor rod. Verify continuity with
multimeter with ohms set at the lowest range.
- 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.
- Check all seals.
- Check if exhaust is re-entering through an open door or
window.
- Clean the glass, see "CARE OF GLASS" section
- DO NOT CLEAN GLASS WHEN HOT.
- If deposits are not cleaned off regularly, the glass may
become permanently marked.
- Tighten door clamps if applicable.
- Restrict vent exit with restrictor plate. See "RESTRICTING
VENTS" section if applicable.
- Remove blockage. In extreme conditions, ice buildup may
occur on the terminal and should be removed. To minimize
this from happening again, it is recommended that the
vent lengths that pass through unheated spaces (attics,
garages, crawl spaces) be wrapped with an insulated mylar
sleeve. Prevent sleeve from sagging. Contact your local
authorized dealer for more information.
- Check venting system parameters (seal, length, rise, etc.).
- Check joint seals and installation.
