Minimum overall height of the vent system and appliance must be 12' (3.66 m) vertical (no offset) or 17' (5.18 m) when an offset up to 45 degrees from the vertical is used. The lower part of the offset must not begin less than 3' (0.914 m) above the top of the fireplace (see Figure 11 ).

Maximum overall height of the vent system and appliance should not exceed 40 feet (12.19m).

Install the B-vent system in accordance with the vent manufacturer's instructions.

CAUTION: THIS APPLIANCE CANNOT BE VENTED HORIZONTALLY.

The gas valve has been set in place and has been pre-wired at the factory. Locate the wall switch (not provided) or optional remote control in the desired location and connect the millivolt wire

(see Figure 12 ).

CAUTION: DO NOT CONNECT THE WALL SWITCH TO A 120V POWER SUPPLY.

Note: The ends of the 18' coiled wire must be connected to the wall switch (not supplied) for the appliance to operate.

B. Electronic Wiring – The electronic appli- ance must be connected to the main power supply. To install, route a 3-wire 120V 60Hz power supply to the appliance junction box and ground.

Locate and install a low voltage (24V) wall switch (not supplied) in the desired location. Connect the low voltage wire to this switch

(see Figure 13 on Page 8).

IMPORTANT: Ground lead must be con- nected to the green screw located on the outlet box. See Figure 16 on page 9.

Failure to do so will result in a potential safety hazard. 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 Cana- dian Electrical Code.)

Note: Refer to the vent manufacturers installa- tion instructions for variations of venting tech- niques. If common venting of several units is contemplated, it should be discussed with an architect and the local Building Department.

Step 5. Field Wiring – Refer to Section A for millivolt appliances and Section B for electronic appliances.

A. Millivolt Wiring – Units are fitted at the factory with an SIT millivolt gas control valve. The valve has been tested with and approved for use with these appliances and is listed accordingly. Refer to Figure 12 for the wiring diagram.
