Installing Bottom Mounting Screws

1.Locate two bottom mounting screw holes. These holes are near bottom on back panel of heater (see figure 9).

2.Mark screws locations on wall.

3.Remove heater from mounting bracket.

4.If installing bottom mounting screw into hollow or solid wall, install wall anchors. Follow steps 1 through 4 under Attaching to Wall using Anchor. If installing bottom mounting screw into wall stud, drill holes at marked locations using 9/64” drill bit.

5.Re-place 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 the 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 se- cured to wall. Do not over tighten.

Note: Do not re-place front panel at this time. Re- place front panel after making gas connections and checking for leaks.

CONNECTING TO GAS SUPPLY FOR PERMANENT INSTALLATION

WARNING: A qualified service person must connect heater to gas supply. Follow all local codes.

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

CAUTION: Never connect heater directly to the Propane supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and Propane/LP supply.

The installer must supply an external regulator. The external regulator will reduce the incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming 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.

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

Installation must include an equipment shutoff valve, union and plugged 1/8” NPT tap. Locate NPT tap within reach of test gauge hookup. NPT tap must be upstream from heater (see figure 12).

*A CSA/AGA certified equipment shutoff valve with 1/8” NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA/AGA certified equipment shutoff valve from your dealer. See Accessories, page 17.

IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.

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 fuel train.

CAUTION: Use pipe joint sealant that is resistant to LP-Gas.

Install sediment trap in supply line as shown in figure 12. Locate sediment trap where it is within reach for clean- ing. A sediment trap traps moisture and contaminants. This keeps them from going into heater. If sediment trap is not installed or is installed improperly, heater may not
