3.5 TROUBLE SHOOTING - SL-550TRS-AUC
With proper installation and maintenance, your new Gas Heater should provide years of trouble-free service.
If you do experience a problem, refer to the Trouble Shooting Guide below. This guide will assist a qualified
service person in the diagnosis of problems and the corrective action to be taken.
SYMPTOM
I. Spark Ignitor will not light pi-
lot after repeated triggering
of red or black button.
II. Pilot will not stay lit after care-
fully following lighting in-
structions.
POSSIBLE CAUSE
A. Defective ignitor (no spark at
electrode).
B. Defective pilot or misaligned
electrode (spark at electrode).
C. No gas or low gas pressure.
D. No L.P. in tank.
A. Defective thermocouple.
CORRECTIVE ACTION
1. Check for spark at electrode and
pilot; if no spark and electrode
wire is properly connected, re-
place ignitor.
1. Using a match, light pilot. If pi-
lot lights, turn off pilot and trig-
ger the red or black button again.
If pilot lights, an improper gas/
air mixture caused the bad light-
ing and a longer purge period is
recommended. If pilot will not
light - check gas at electrode
and pilot - should be 1/8 inch
(3.2mm) to have a strong spark.
If OK, replace pilot.
1. Check unit's shut-off valve and
remote shut-off valves from fire-
place. Usually there is a valve
near the main. There can be
more than one (1) valve between
the fireplace and main.
2. Low pressure can be caused by
a variety of situations such as a
bent line, too narrow diameter of
pipe or even low line pressure.
Check for kinked lines. If none,
consult with plumber or gas sup-
plier.
3. Check L.P. (propane) tank. Re-
fill the fuel tank.
1. Check that pilot flame impinges
on thermocouple. Clean and/ or
adjust pilot for maximum flame
impingement.
2. Ensure that the thermocouple
connection at the gas valve is
fully inserted and tight (hand tight
plus 1/4 turn).
