Troubleshooting - Superior Fireplaces BRT4036TMN Installation & Operation Instructions

Note: Before troubleshooting the system, make sure the gas shutoff valve is ON. The two most common causes of a malfunctioning gas
appliance are:
1. Loose wiring connections
2. Construction debris clogging pilot and/or gas control valve filter
OBSERVED PROBLEM
Pilot will not light
Pilot will not stay lit
No gas to burner, although wall switch and valve
are set to the ON position
Frequent pilot outage
Pilot goes out when wall switch is ON
Spark ignitor will not light pilot after repeated
triggering of red button
Fireplace produces a clicking/ticking noise just
after burner is lit or shut off

TROUBLESHOOTING

POSSIBLE CAUSE
1. No gas supply or shutoff valve is OFF
2. Air in gas line
3. Construction debris clogging pilot orifice
4. Low gas pressure
5. Control valve knob is not on the PILOT posi-
tion
6. Kinked pilot line
7. Bad valve
8. Vent damper not fully open
1. Loose wiring on thermopile to regulator valve.
No millivolt current is being sent back to
regulator
2. If valve knob and wall switch are in the ON
position, probable defective regulator valve
3. Vent damper not fully open
1. Wall switch wires defective or too long
2. Thermopile not generating sufficient voltage
1. Pilot flame may be too low, causing safety
pilot to "drop out"
2. Improper venting or excessive blockage
1. Millivolt output on thermopile too high
1. Defective ignitor (no spark at electrode)
2. Defective pilot or misaligned electrode at pilot
(spark at electrode)
3. No gas or low gas pressure
4. If using propane/LP gas, no propane/LP gas
in tank
1. Metal expanding while heating or contracting
while cooling

REMEDY
1. Check to see if you have gas supply
2. Hold regulator control valve in the PILOT
position for 2 to 3 minutes to purge air. If
you smell gas stop and wait for a few minutes
before trying to light fireplace
3. Remove debris and dirt, inspect and clean any
other possible obstructions
4. Contact your gas supplier
5. Refer to section on pilot lighting
6. Have a qualified technician replace pilot line
7. Replace regulator valve (see Accessories, page
26)
8. Open vent damper until fully locked in OPEN
position
1. Check wiring connections. Refer to wiring
diagram shown in Wall Switch Installation,
page 10
2. Have a qualified technician replace valve
3. Open vent damper until fully locked in OPEN
position
1. Check electrical connections
2. See Pilot will not stay lit, above
1. Clean and adjust pilot flame for maximum
flame impingement on thermopile
2. Have vent system inspected, including
termination cap. Remove any restriction or
obstruction
1. Replace thermopile
1. Check for spark at electrode and pilot. If no
spark and electrode wire is properly con-
nected, replace ignitor
2. Using a match, light pilot. If pilot lights, turn
off pilot and trigger the red button again.
If pilot lights, an improper gas/air mixture
caused the improper lighting and a longer
purge period is recommended. If pilot will
not light, check gap at electrode and pilot.
Gap should be 1/8" to have a strong spark. If
okay, replace pilot
3. A) Check remote shut off valves from
fireplace. Usually there is a valve near the
fireplace and sometimes there is a valve near
the main. There can be more than one valve
between fireplace and main
B) Low pressure can be caused by a variety of
situations such as bent line, or gas supplier
4. Check propane/LP supply and contact local
propane/LP supplier
1. This is normal with most fireplaces. If noise
is excessive, contact qualified service person
