INSTALLATION
Continued
4.If installing bottom mounting screws into hollow or solid wall, install wall anchors. Follow steps 1 through 4 under Attaching To Wall Anchor Method, page 10.
If installing bottom mounting screw into wall stud, drill holes at marked locations using 9/64" drill bit.
5.Replace heater onto mounting bracket.
6.Place spacers between bottom mounting holes and wall anchor or drilled hole.
7.Hold spacer in place with one hand. With other hand, insert mounting screw through bottom mounting hole and spacer. Place tip of screw in opening of wall anchor or drilled hole.
8.Tighten both screws until heater is firmly secured to wall. Do not over tighten.
Note: Do not replace front panel at this time. Replace front panel after making gas connec- tions and checking for leaks (see pages 11 through 13).
Mounting heater to floor
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.

Figure 13 - Installing Base Feet
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" diameter hole, 3/4" deep. (Do not use anchors in wood floors).
If mounting base to a concrete floor, drill with 1/4" diameter concrete drill bit, 13/8" 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:Aqualifiedservice personmustconnectheatertogas supply. Follow all local codes.
WARNING: For natural gas, never connect heater to private
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.
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" of water. If you do not reduce incoming gas pressure, 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.
