INSTALLATION

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 

the external regulator between the 

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.

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, 1

3

/

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.
