Solution
Turn gas control knob to ON position.
Turn the ON/OFF rocker switch to ON position.
Put wall switch, remote control, or thermostat in heat demand
position.
Remove blockage as necessary.
Check remote, thermostat, or wall switch wires for proper
connection.
Place jumper wires across terminals at switch. If the burner
lights, replace the defective switch, thermostat, or batteries in
remote control as necessary.
If switching device checks out as described above, place
jumper wires across switches on the gas valve. If the burner
lights, the switching wires are faulty or connections are bad.
Replace as necessary.
Tighten if necessary.
Free pinched wires if necessary.
Refractory panels must be tight against firebox walls. It may
be necessary to secure panels with high-temperature sealant,
especially around the intake duct.
Check LP (propane) tank. Refill if necessary.
Refer to Section 8.2 Glass Frame Assembly on page 27.
¼ in (6 mm) per 12 in (30 cm) is required on horizontal venting
