*This dimension can be reduced to 41 inches (1041 mm). This results in 0 in. (0 mm)
clearance between framing and unit framing spacers. (The 41 in. dimension permits
easier fireplace installation, if unit is installed after framing is erected.)
**Based on 5/8" drywall. Use 23" for 1/2" drywall.

Slip the first 6 inch (152 mm) section of B-
Vent over the fireplace flue outlet and secure
with four sheetmetal screws (# 8 or larger),
and install the remainder of the B-Vent to the
outside. Minimum overall height of the vent
system and appliance must be 10' (2.54 m)
vertical - no offset (see Figure 6 ); or 12' (3.7
m) when an offset up to 60 degrees from the
vertical is used - this offset may start at the
fireplace flue collar (see Figure 7 ). The
maximum overall height of the vent system
and appliance should not exceed 40 feet.
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 in-
stallation instructions for variations of vent-
ing techniques. If common venting of sev-
eral units is contemplated, it should be dis-
cussed with an architect and the local Build-
ing Department.
Do not place insulation materials within 1 in.
of the gas vent system.
