Note: The nailing flanges and the area directly
behind the nailing tabs are exempt from the
clearances described on the fireplace clear-
ance label.
Step 4. Install the Vent System and
Exterior Termination
Slip a 10" (254 mm) B-Vent system over the
appliance collar (Figure 10 ) and secure with
four sheetmetal screws (# 8 or larger). 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.
Note: Refer to the vent manufacturers instal-
lation instructions for variations of venting
techniques. 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 fac-
tory 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.
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 appliance
must be connected to the main power supply.
To install, route a 3-wire 120V 60Hz power sup-
ply 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
connected 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 appli-
ance 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.)
