a. Main shut-off valve closed.
• Make sure that the shut-off valve located on the pipe
supplying gas to the replace is open.
b. Air in the gas line.
• Light a match, turn valve knob to "PILOT" position and
depress, keep match near pilot burner until it lights.
c. Valve knob in "OFF" position.
• Turn valve knob to "PILOT" position and depress, keep
match near pilot burner until it lights.
d. Pilot orice plugged up, not allowing gas to ow.
• This repair requires tools and some degree of experience.
Ask serviceman for assistance.
e. No gas supply to the replace.
• Check plumbing to see if gas replace has been hooked
up to the gas supply line.
• Propane tanks is empty.

a. Defective pilot generator (thermopile), remote wall switch.
• Check pilot ame. Must impinge on thermopile. Clean
and or adjust pilot for maximum ame impingement on
thermopile.
• Be sure wire connections from thermopile at gas valve
terminals are tight and thermopile is fully inserted into
pilot bracket.
• One of the wall switch wires may be grounded. Remove
wall switch wires from valve terminals if pilot now stays
lit, trace wall switch wiring for ground. May be grounded
to appliance or gas supply.
• Check thermopile with millivolt meter. Take reading at
thermopile terminals of gas valve. Should read 325 mil-
livolts minimum while holding valve knob depressed in pilot
position and wall switch "Off." Replace faulty thermopile
if reading is below specied minimum.
b. Defective automatic valve operator — Turn valve knob to
"On." Place wall switch to "On" millivolt meter should read
greater than 100 M.V. If the reading is okay and the burner
does not come on, replace the gas valve.
c. Defective thermopile.
• Check all connections and try.
• If still not operating, disconnect lead between thermo-
couple switch and valve operator. Then disconnect lead
to pilot magnet and connect to valve operator terminal
(TP, TH). If pilot remains lit fault lies with thermocouple.
Check that bulb is in proper location. If still not working
replace thermocouple (see drawing in manual for ad-
ditional information).

a. Wall switch or wires defective.
• Check wall switch and wires for proper connections.
Jumper wire cross terminals at wall switch, if burner
comes on, replace defective wall switch. If okay, jumper
wires cross wall switch wires at valve, if burner comes
on, wires are faulty or connections are bad.
b. Thermopile may not be generating sufcient millivoltage.
• Replace.
c. Plugged burner orice.
• Check burner orice for debris and remove.

a. Defective thermocouple.
• Check that pilot ame impinges on thermocouple. Clean
and/or adjust pilot for maximum ame impingement.
• Ensure that the thermocouple connection at the gas valve
is fully inserted and tight (hand tight plus 1/4 turn) faulty
thermopile if reading is below specied minimum.
• Disconnect the thermocouple from the valve, place one
millivolt meter lead wire on the tip of the thermocouple and
the other meter lead wire on the thermocouple copper lead.
Start the pilot and hold the valve knob in. If the millivolt
reading is less than 15 mv, replace the thermocouple.
b. Defective valve.
• If thermocouple is producing more than 15 millivolts,
replace faulty valve.
