Measure the thickness of the wall as shown in Figure 25.

1. If any of the following are long trim them according to the thickness of the wall, (see Table 3):
   • (B) vent pipe
   • (C) vent-air intake pipe
   • (i) insulation
   • (D) rod
2. The hole at the outside of the wall must be a square of 11-1/4” (286 mm) x 11-1/4” (286 mm).
3. Slide the heat shield (K) into the 11-1/4” (286 mm) x 11-1/4” (286 mm) square hole. Secure the heat shield (K) to the wall bracket using the appropriate hardware.
4. From the outside of the wall, screw the rod (D) slightly onto the support located inside the appliance flue outlet.
5. Wrap the vent-air intake pipe (C) with the provided insulation (i) (foil side out) and place the provided strip of tape (H) down the seam to secure it.
6. Slide the smaller vent pipe (B) (from outside your house) through the hole in the wall and attach it to the mounted heater inside your house. Be sure the vent pipe is snug and engaged to the heater. Then slide the larger Vent‐Air Intake Pipe, with the insulation wrapped and taped to the outside of the pipe, through the same hole and over the smaller Vent Pipe (B), and attach to the heater.
   • NOTE: The insulation wrap (i) must be wrapped and secured with the tape on the outside of the larger Vent‐Air Intake Pipe (C). The insulation is NOT to be wrapped in between the Vent Pipe (B) and the Vent‐Air Intake Pipe (C).

Note: For additional security, the outdoor mounting plate (F) can be attached to the outside of the wall using the appropriate hardware for mounting to the surface of the building. The outdoor mounting plate (F) must be positioned flush to the wall and sealed with a non-hardening mastic (silicone caulk).
8. Before attaching the vent cap (A) to the exterior wall, run a bead of non-hardening mastic (silicone caulk) around its outside edge, to make a seal between it and the outdoor mounting plate (F).
9. Slide the vent cap (A) into position and secure it into place using the provided nut (E). Tighten nut (E) down until the vent cap (A) leans against the outdoor mounting plate (F).
10. Hand-bend the rain shield (J) into a semi-circle and align it with the mounting holes located in the outdoor mounting plate (F). Secure the rain shield (J) to the outdoor mounting plate (F) using three (3) small screws (vi) included in the hardware packet.

INSTALLING THE THERMOSTAT SENSOR
In order to protect the thermostat sensor from any damage during shipping, or while handling it before it is installed, the thermostat sensor has not been attached to its final location in the appliance. So, once the heater is installed, the thermostat sensor must be placed and secured in position. To do so, follow these steps:

1. Reach in through the bottom of the unit and cut the cable tie holding the thermostat sensor to the unit.
2. Place the thermostat sensor under the right bottom of the bracket and attach it with the provided medium screw (i) that fixes the appliance to the bracket as shown.

GAS CONNECTION

1. We recommend using only new black iron or steel pipe. CHECK LOCAL CODES.
2. The gas supply line shall be sized and installed to provide a sufficient supply of gas to meet the maximum demand of the heater without undue loss of pressure.
3. The sealant used on the threaded joints of the gas pipe must be a type resistant to the action of L.P. Gas. (This sealant should be applied lightly to main threads to ensure excess sealant does not enter lines.)
4. The gas supply system must include a manual shut-off valve and connection in the line, so the heater can be disconnected for servicing.
5. Include a drip leg (trap) and a plugged 1/8” N.P.T. tapping in the line. The tapping should be accessible for test gauge connections upstream of the gas supply connection to the heater.

IMPORTANT:
HOLD THE GAS INLET OF THE APPLIANCE WITH WRENCH WHEN CONNECTING IT TO GAS PIPING AND/OR FITTINGS.
