Attaching To Wall Stud Method For attaching heater to wall studs

1.Drill holes at marked locations using 9/64" drill bit. Holes must be level to prevent com- plications with front panel.

2.Tighten screws until screw head is 1/8" away from wall.

Attaching To Wall Anchor Method

For attaching heater to hollow walls (wall areas be- tween studs) or solid walls (concrete or masonry).

1.Drill holes at marked locations using 5/16" drill bit. Holes must be level to prevent com- plications with front panel. For solid walls

(concrete or masonry), drill at least 1" deep.

2.Fold wall anchor as shown in Figure 7.

3.Insert wall anchor (wings first) into hole. Tap anchor flush to wall.

4.For thin walls (1/2" or less), insert red key into wall anchor. Push red key to “pop” open anchor wings. IMPORTANT: Do not hammer key! For thick walls (over 1/2" thick) or solid walls, do not pop open wings.

CONNECTING TO GAS SUPPLY

WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator.

WARNING: A qualified service personmustconnectheatertogas supply. Follow all local codes.

WARNING: For natural gas, never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

IMPORTANT: For natural gas, check gas line pressure before connecting heater to gas line. Gas line pressure must be no greater than 10.5" of wa- ter. If gas line pressure is higher, heater regulator damage could occur.
