PROBLEM OBSERVED POSSIBLE CAUSE
CORRECTIVE MEASURE
(continued)
Pilot burning, no gas
to burner, valve knob
“ON”, REMOTE/ OFF/ON
switch “ON.”
(continued)
Thermopile may
not be generating
sufficient millivolts.
Check the thermopile with a millivolt meter. Take the reading at
TH-TP & TP terminals of the gas valve. The meter should read 350
millivolts minimum, while holding the valve knob depressed in the
PILOT position, with the pilot lit, and the REMOTE/OFF/ON switch
in the OFF position. Replace the faulty thermopile if the reading is
below the specified minimum.
With the pilot in the ON position, disconnect the thermopile
leads from the valve. Take a reading at the thermopile leads.
The reading should be 350 millivolts minimum. Replace the
thermopile if the reading is below the minimum.
Defective valve.
Turn valve knob to ON. Place REMOTE/OFF/ON switch
to ON. Check with millivolt meter at thermopile terminals.
Millivolt meter should read greater than 200 millivolts. If the
reading is okay and the main burner does not ignite, replace
the gas valve.
Plugged main burner
orifice.
Check main burner orifice for blockage and remove.
Frequent pilot outage
problem.
Pilot flame may be
too high or too low, or
blowing (high),
causing pilot safety to
drop out.
"Clean and adjust flame for maximum flame impingement
on the thermocouple. Follow lighting instructions carefully."
The pilot and main
burner extinguish while
in operation.
No Propane in tank.
Check Propane tank. Refill fuel tank.
Inner vent pipe
leaking exhaust
gases back into
system
Check for leaks.
Glass too loose,
gasket leaks in
corners after usage.
Be certain glass assembly is installed correctly.
Horizontal vent
improperly pitched.
The horizontal vent cap should slope down only enough
to prevent any water from entering the unit. The maximum
downwards slope is 1/4 inch.
Bad thermopile or
thermocouple.
Replace if necessary.
Improper vent cap
installation.
Check for proper installation and freedom from debris or
blockage.
