MOUNTING HEATER TO FLOOR (OPTIONAL)

Mounting Base Feet to Heater

1.Lay heater cabinet on its back on a table with the heater bottom overhanging the table edge.

2.Align holes in base foot with mounting holes on bottom of cabinet (see Figure 13).

3.Secure base foot to heater using sheet metal screws.

4.Repeat for other side.

Mounting Base Feet to Floor (Where required by local code)

1.Remove front cover (see Removing Front Panel of Heater, page 9).

2.Position heater with base feet in desired loca- tion. Mark holes for drilling. Remove heater with base.

3.For carpeted floors, make a small cut with a sharp knife at marked locations prior to drill- ing. If mounting base to a wood floor, drill 1/8" (3.2 mm) diameter hole, 3/4" (1.9 cm) deep. (Do not use anchors in wood floors).

If mounting base to a concrete floor, drill with 1/4" (6.4 mm) diameter concrete drill bit, 13/8" (3.5 cm) into floor. Insert anchors completely into holes.

4.Reposition heater with base feet over holes. Secure base to floor with wood screws. See Figure 13.

CONNECTING TO GAS SUPPLY

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

WARNING: A qualified ser- vice person must connect heater to gas 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 inches of water. If gas line pressure is higher, heater regula- tor damage could occur.

CAUTION: For propane/LP gas, never connect heater di- rectly to the propane/LP supply. This heater requires an external regulator (not supplied). Install theexternalregulatorbetweenthe heater and propane/LP supply.

For propane/LP gas, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pres- sure, heater regulator damage could occur. Install the external regulator with the vent pointing down as shown in Figure 14, page 12. Pointing the vent down protects it from freezing rain or sleet.
