Installing Bottom Mounting Screws
1.Locate two bottom mounting holes. These holes are near bottom on back panel of heater (see Figure 12).
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 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.

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

supply. Follow all local codes. | |
WARNING: For natural | |
gas, never connect heater to | |
private | |
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 13. Pointing the vent down | |
protects it from freezing rain or sleet. | |
