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, and
air terminal locations for either system are set out in this manual 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:
PART
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  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  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 /  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,  at roof terminal kit GD412 or periscope kit GD401 (for wall penetration below grade). With  exible
venting, in conjunction with the various terminations, use either the 5 foot vent kit GD420 or the 10 foot 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. The maximum allowable vertical vent length is 40 feet. The maximum number of vent connections is two
horizontally or three vertically (excluding the appliance and the air terminal connections) when using  exible venting.
Horizontal runs may have a 0”" rise per foot however for optimum performance it is recommended that all horizontal
runs have a minimum 1/4”" rise per foot using  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
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”" air gap
all around between the inner liner and outer liner is required for safe operation.
