INSTALLATION
Continued
4. | If installing bottom mounting screw into |
| hollow or solid wall, install wall anchor. |
| Follow steps 1 through 4 under Attach- |
| ing To Wall Anchor Method, page 8. If |
| installing bottom mounting screw into |
| wall stud, drill holes at marked loca- |
| tions using 9/64" drill bit. |
5. | Replace heater onto mounting bracket. |
The installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure between 11 and 14 inches of water. If youdonotreduceincominggaspressure,heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 13. Pointing the vent down protects it from freezing rain or sleet.
CAUTION: Use only new, black iron or steel pipe. Inter-
6. | Place spacer between bottom mount- |
| ing hole 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 screw 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 page 10). |

CONNECTING TO GAS SUPPLY
WARNING: This appliance re- quires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator.
WARNING: A qualified service person must connect heater to gas supply. Follow all local codes.
CAUTION:Neverconnectheater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and propane/LP supply.

| Regulator | Install sediment trap in supply line as shown | |
|
|

|
|
| in Figure 14. Locate sediment trap where it | |
|
|
| is within reach for cleaning. Locate sedi- | |
|
|
| ment trap where trapped matter is not likely | |
|
|
| to freeze. A sediment trap traps moisture | |
|
|
| and contaminants. This keeps them from | |
|
|
| going into heater controls. If sediment trap | |

|
| is not installed or is installed wrong, heater | |
