These vent kits allow for either horizontal or vertical venting of the
fi replace. The maximum allowable horizontal run is 20 feet. The
maximum allowable vertical vent length is 40 feet. The maximum
number of vent connections is two horizontally or three vertically
(excluding the fi replace and the air terminal connections) when us-
ing fl exible venting.
For optimum fl ame appearance and fi replace performance, keep
the vent length and number of elbows to a minimum.

HORIZONTAL VENT SECTIONS: - A minimum clearance
of 1" at the bottom and sides of the vent and 2" at the top on
all horizontal runs to combustibles is required. The fi restop
spacer (W010-1774) supplied with the unit must be used to
maintain this clearance.
VERTICAL VENT SECTIONS: - A minimum of 1" all around
the vent pipe on all vertical runs to combustibles is required
except for clearances in fi replace enclosures. See "MINIMUM
ENCLOSURE CLEARANCES" section. Use fi restop spacer
W500-0096 (not supplied).

For vent systems that provide seals on the inner exhaust fl ue, only the
outer air intake joints must be sealed using a red high temperature
silicone (RTV). This same sealant may be used on both the inner
exhaust and outer intake vent pipe joints of all other approved vent
systems except for the exhaust vent pipe connection to the fi replace
fl ue collar which must be sealed using the black high temperature
sealant Mill Pac.

When using Wolf Steel venting components, use only approved Wolf
Steel rigid / fl exible components with the following termination kits:
WALL TERMINAL KIT GD222, or 1/12 to 7/12 PITCH ROOF TERMI-
NAL KIT GD110, 8/12 to 12/12 ROOF TERMINAL KIT GD111, FLAT
ROOF TERMINAL KIT GD112 or PERISCOPE KIT GD201 (for wall
penetration below grade). With fl exible venting, in conjunction with
the various terminations, use either the 5 FOOT VENT KIT GD220
or the 10 FOOT VENT KIT GD330.

REFER TO THE SECTION APPLICABLE TO YOUR INSTALLATION.
VENTING LENGTHS
THE BGD36CF(G) USES: 4" EXHAUST / 7" AIR INTAKE VENT PIPE
THE BGD42CF USES: 5" EXHAUST / 8" AIR INTAKE VENT PIPE
For safe and proper operation of the fi replace follow the venting instruction exactly. Deviation from the minimum vertical vent length
can create diffi culty in burner start-up and/or carboning. Provide a means for visually checking the vent connection to the fi replace
after the fi replace is installed. Vent lengths that pass through unheated spaces (attics, garages, crawl spaces) should be insulated
with the insulation wrapped in a protective sleeve to minimize condensation.
VENTING
HORIZONTAL VENT SECTIONS: A minimum clearance of 2"
all around the vent pipe on all horizontal runs to combustibles
is required. Use fi restop spacer W010-1778 (supplied).
VERTICAL VENT SECTIONS: A minimum of 1" all around the
vent pipe on all vertical runs to combustibles is required. Use
fi restop spacer W500-0028 (not supplied).
For optimum performance, it is recommended that all horizontal
runs have a 1" rise per foot.
