Step 6. Installing the Optional Remote Wall Switch – The standard millivolt system comes from the factory wired as shown in Figure 12. Select a convenient location for the remote wall switch and connect the wiring to the appliance (Figure 13 ).

CAUTION: DO NOT CONNECT THE OP- TIONAL REMOTE SWITCH TO A 120V POWER SUPPLY.

Note: The optional rocker switch is mounted to the appliance and wired in the same way as the remote wall switch.

Step 7. Installing the Optional Forced Air Blower Kit Wiring – A receptacle plate is pro- vided for the installation of the FAB-1100 forced air blower kit (optional). Electrical power must be provided to this plate to operate the blower.

Route a 3-wire, 120Vac power line with control switch to the lower left front corner of the appliance.

Note: Supply wires may be alternatively connected to the outlet using the screw terminals, however the black supply wire must be ganged wired to the same terminal that the pre-wired black wire is attached to and the white supply wire must be connected to the opposite side of the outlet.

Supply wires are to be connected to the outlet as shown in Figure 14, ensuring that the polar- ity (as determined by the colors of the wires) is exactly as shown. The black and red wire loop must be left intact, with the mating connectors connected.

IMPORTANT: Ground lead must be connected to the green screw located on the junction box cover plate. Failure to do so will prevent the appliance from operating. The appliance must be electrically grounded in accordance with local codes or, in the absence of local codes, the National Electrical Code, ANSI/NFPA 70-(latest edition). (In Canada, the current CSA C22-1 Canadian Electrical Code.)

The forced air blower kit may be mounted at initial appliance installation or at any time there- after. Follow the instructions provided with the blower kit.

Finished Wall Details

It is sometimes best to frame the appliance after it has been positioned in place. Frame with 2 x 4s or heavier lumber. Always frame in accordance with local building codes.

Note: The header may rest on the top spacers but must not be notched to fit around them.

In order to install the appliance facing flush with the finished wall, position the framework to accommodate the thickness of the finished wall (Refer to Figures 2, 3 and 5 ).

If you live in a cold climate, seal all cracks around your appliance with noncombustible material and wherever cold air could enter the room. It is especially important to insulate outside chase cavity between studs and under floor on which appliance rests, if floor is above ground level.
