Use only Wolf Steel, Metal-Fab, BDM, Simpson Dura-Vent, or Selkirk Direct Temp 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 Metal-Fab, BDM, Simpson
Dura-Vent, or Selkirk Direct Temp, follow the installation procedure provided with the venting components or on the website
for your venting supplier.
A starter adaptor must be used with the following vent systems and may be purchased through Wolf Steel or from the
corresponding supplier listed below:

Connections made by means of an adaptor at the appliance, as well as the connection at the vent terminal must be sealed.
RTV sealant may be used on both the inner exhaust and outer intake vent pipe joints of all other approved vent systems, ex-
cept for the exhaust vent pipe connection to the appliance fl ue collar which must be sealed using the black high temperature
sealant Mill Pac.
For all vent systems is strongly recommend for all installations but required when power venting the appliance, that the outer
air intake joints are sealed using either high temperature silicone (RTV) or a suitable aluminum tape that covers each joint in
the vent system entirely around its circumference. This will ensure the best performance in every application and avoids per-
formance or condensation concerns that may occur in "tightly" constructed homes, particularly those in cold climates.
When using Wolf Steel venting components, use only approved Wolf Steel rigid / fl exible components with the following
termination kits: wall terminal kit GD422R-2 or ST58U-1, or 1/12 to 7/12 pitch roof terminal kit GD410, 8/12 to 12/12 roof
This template must be used in conjunction with templates 7.2.1 or 7.2.2, depending on
terminal kit GD411, fl at roof terminal kit GD412 or periscope kit GD401 (for wall penetration below grade). With fl exible
termination shape (i.e. round, or round and square). See appropriate templates folder.
venting, in conjunction with the various terminations, use either the 5 foot (1.5m) vent kit GD420 or the 10 foot (3.1m) vent kit
GD430.
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.
Horizontal runs may have a 0" (0mm) rise per foot/meter however for optimum performance it is recommended that all
horizontal runs have a minimum 1/4" (21mm) rise per foot/meter using fl exible venting. For safe and proper operation of the
appliance, follow the venting instructions exactly.
A terminal shall not terminate directly above a sidewalk or paved driveway which is located between two single family dwell-
ings and serves both dwellings. Local codes or regulations may require different clearances.
Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1¼" (31.8mm) air
gap all around between the inner liner and outer liner is required for safe operation.
