Ipi Troubleshooting - Heat-N-Glo Gas Fireplace Owner's Manual

IPI Troubleshooting

Symptom
1. Nothing happens
when ON/OFF switch
is turned on (pilot
does not spark).
2. The main burner
does not light and the
igniter is sparking.
3. Pilot stays lit (should
turn off when ON/
OFF is turned off).
Possible Cause
a. Low voltage/or bad
lead wires.
b. Faulty pilot device.
c. Faulty igniter wire.
a. Loose sensor or
spark wire.
b. No fuel supply.
c. Air in gas line.
d. Loose orange wire
to valve.
e. Black controller wire
not connected to
ground.
f. Flame sensor not in
pilot flame.
g. Loose green wire to
valve.
h. Low voltage.
I. Faulty module or
valve.
a. Loose connection on
green wire.
b. Faulty valve.
c. Faulty module.
Corrective Action
Check voltage on AC terminals of
module: should read 2.8 to 3.2 VAC.
Check and/or replace batteries. Confirm
that wire connections are secure.
Gap between electrode and pilot hood
should be approx. 3/16”. Check pilot for
damage (cracked insulator on spark
electrode, etc.).
Check wire for cracked casing, cuts,
shorts, etc.
Ensure spark and senor wires are
connected.
Ensure that gas shut off is turned on.
Ensure the fuel supply is properly
connected.
Purge gas line of air.
Connect wire to orange terminal on
valve.
Connect black wire to ground.
Determine cause of improper flame on
the sensor, replace if necessary.
Connect green wire to valve.
Test voltage at battery terminals (red
and black wires). If it is not at least 2.7
VAC, find source of low voltage problem
(replace batteries or 3V adapter.)
Check all wire connections including the
ground wire. If OK then remove green
wire from valve with the pilot lit.
Connect a wire from red battery
connection (red wire) to green terminal
of valve. If valve opens and burner
lights, replace the module. If it does not,
replace the valve.
Check connection of green wire to
green terminal on valve.
Disconnect orange wire on valve. If the
pilot remains lit replace faulty valve.
Disconnect orange wire on valve. If the
pilot turns off then check all connections
and continuity - if no fault is found in
wiring then replace faulty module.
