Placing Heater On Mounting Bracket

1.Locate two horizontal slots on back panel of heater.

2.Place heater onto mounting bracket. Slide horizontal slots onto stand-out tabs on mounting bracket.

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 connections and checking for leaks (see pages 8-9).

CONNECTING TO GAS SUPPLY

CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

Typical Inlet Pipe Diameters

20,000 Btu/Hr models

3/8" or greater

30,000 Btu/Hr models

1/2" or greater

Installation must include a manual shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from

Installing Bottom Mounting Screws

1.Locate two bottom mounting holes. These holes are near bottom on back panel of heater (see Figure 11).

Figure 11 - Installing Bottom Mounting Screws

2.Mark screw locations on wall.

3.Remove heater from mounting bracket.

4.If installing bottom mounting screws into hollow or solid wall, install wall anchors. Follow steps 1 through 4 un- der Attaching To Wall Anchor Method, page 7.

If installing bottom mounting screw into wall stud, drill holes at marked lo- cations using 9/64" drill bit.

5.Replace heater onto mounting bracket.

6.Place spacers between bottom mount- ing holes and wall anchor or drilled hole.

NOTICE: A qualified service per- son must connect heater to gas supply. Follow all local codes.

CAUTION: Never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator be- tween the heater and propane/LP supply.

The installer must supply an external regu- lator. 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 incom- ing gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure

12.Pointing the vent down protects it from freezing rain or sleet.

heater (see Figure 13, page 9).

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.

CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.

Install sediment trap in supply line as shown in Figure 13, page 9. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps mois- ture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.
