**
When a vertical rise is used as part of the venting confi guration, a 0" rise per foot is acceptable.
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 TERMINAL 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
.
For optimum
fl
ame appearance and
fi
replace performance, keep the vent length and number of elbows to a
minimum.
The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify that
it is unobstructed and undamaged.
Wolf Steel rigid and
fl
exible venting systems must not be combined.
Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp and American Metal Amerivent venting systems must not be
combined.
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 4" vent connections is two horizontally or
three vertically (excluding the fi replace and the air terminal connections) when using fl exible vent pipe.
For optimum performance, it is recommended that all horizontal runs have a 1" rise per foot.

HORIZONTAL VENT SECTIONS
A minimum clearance of 1" at the bottom and sides and 2" at
the top of the vent pipe on all horizontal runs to combustibles
is required. Use fi restop spacer W010-1777 (supplied).
HORIZONTAL VENT SECTIONS
A minimum clearance of 1" at the bottom and sides and 2" at
the top of the vent pipe on all horizontal runs to combustibles
is required. Use fi restop spacer W010-1774 (supplied).
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).
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 safe and proper operation of the
fi
replace follow the venting instructions exactly.
Deviation from the minimum or maximum vertical vent length can create diffi culty in burner start-up and/or
carboning.
Under extreme vent con
fi
gurations, allow several minutes (5-15) for the
fl
ame to stabilize after ignition.
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.
Provide a means for visually checking the vent connection to the fi replace after the fi replace is installed.
Use a fi restop, vent pipe shield or attic insulation shield when penetrating interior walls, fl oor or ceiling.
