3.5 TROUBLE SHOOTING - ATS-AUST
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
pilot after repeated trigger-
ing of red button.
II. Pilot will not stay lit after
carefully following lighting
instructions.
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 button again. If pilot
lights, an improper gas/air mix-
ture caused the bad lighting and
a longer purge period is recom-
mended. 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
heater. Usually there is a valve
near the main. There can be
more than one (1) valve between
the heater 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.
1. 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).
