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:

Duravent
Amerivent
Direct Temp
SuperSeal
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.
When using Wolf Steel venting components, use only approved Wolf Steel rigid / fl exible components with the
following termination kits: wall terminal kit GD422-1, GD422R-1, or 1/12 to 7/12 pitch roof terminal kit GD410, 8/12 to
12/12 roof terminal kit GD411, fl at roof terminal kit GD412 or periscope kit GD401 (for wall penetration below grade).
With fl exible 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. When terminating horizontally, the
maximum allowable horizontal run is 20 feet (6.1m). When terminating vertically, 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" rise per foot or 21mm per 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 fam-
ily dwellings 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.
