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.

VENT INSTALLATIONS
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 confi 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.
