3.1 VENTING LENGTHS AND COMPONENTS
Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent or Metal-Fab
venting components. Minimum and maximum vent lengths, for both horizontal and vertical installations,
clearances from vent pipes to combustibles and air terminal locations as set out in this manual apply to
all vent systems and must be adhered to. For Simpson Dura-Vent, Selkirk Direct Temp, American Metal
Amerivent and Metal-Fab follow the installation procedure provided with the venting components.
A starter adaptor must be used with the following vent systems and may be purchased from the
corresponding supplier:
For Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent and Metal-Fab follow the
installation procedure found on the website for your venting supplier.
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 appliance fl ue collar which must be sealed using the black high temperature sealant Mill Pac. High
temperature sealant must be ordered separately.
When using Wolf Steel venting components, use only approved Wolf Steel rigid / fl exible components with
the following termination kits: wall terminal kit
GD-222
,
GD-222R
, or 1/12 to 7/12 pitch roof terminal kit
GD-110
, 8/12 to 12/12 roof terminal kit
GD-111
, fl at roof terminal kit
GD-112
or periscope kit
GD-201
(for
wall penetration below grade). With fl exible venting, in conjunction with the various terminations, use either
the 5 foot (1.5m) vent kit
GD-220
or the 10 foot (3.1m) vent kit
GD-330
.
For optimum fl ame appearance and appliance 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.
Rigid and fl exible venting systems must not be combined. Different venting manufacturer components
must not be combined.
These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable
horizontal run is 20 feet (6.1m). The maximum allowable vertical vent length is 40 feet (12.2m). The maximum
number of vent connections is two horizontally or three vertically (excluding the appliance and the air
terminal connections) when using fl exible venting.

** When a vertical rise is used as part of the venting configuration, a 0" (0mm) rise per foot is acceptable.
For optimum performance, it is recommended that all horizontal runs have a 1" (25mm) rise per foot.
