Propane/LP Gas

Installing Refractory and Front Panel

WARNING: Examine refrac- tory panel. If damaged, do not operate heater. See Replace- ment Parts, page 21.

1.Gently lift refractory and position into heater. Take care not to damage refractory. Ensure refractory sits behind preforated tab. (see Figure 15). If refractory is damaged call the phone num- ber found under Replacement Parts, page 21.

CAUTION: Refractory may shift inside heater. When install- ing or removing front panel, use caution to prevent refractory from falling.

2.Install front diffuser as shown in Figure 15.

3.Install front panel of heater by placing slots on each side over and down onto shoulder screws (see Figure 15).

A.This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly.

B.BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the ﬂoor because some gas is heavier than air and will settle on the ﬂoor.

WHAT TO DO IF YOU SMELL GAS

•Do not try to light any appliance.

•Do not touch any electric switch; do not use any phone in your building.

•Immediately call your gas supplier from a neighborʼs phone. Follow the gas supplierʼs instructions.

•If you cannot reach your gas supplier, call the ﬁre department.

C.Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, donʼt try to repair it, call a qualiﬁed service technician. Force or attempted repair may result in a ﬁre or explosion.
