3.2 VENTING LENGTHS AND COMPONENTS

The vent connection to the appliance can be viewed by removing the bafﬂ e from the top, inside of the ﬁ rebox.

Use only Wolf Steel 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. Use only Wolf Steel Ltd. ﬂ exible vent components with the Wolf Steel Ltd. GD179

termination kit. This appliance uses a 3” (76.2mm) diameter exhaust and a 5” (127mm) diameter intake

coaxial vent system.

All outer pipe joints of these venting systems must be sealed using Red RTV and/or Mill Pac high temperature

sealant (not supplied) hereafter referred to as high temperature sealant W573-0002 (Red RTV) and the high

temperature sealant W573-0007 (Mill Pac).

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.

With ﬂ exible venting, in conjunction with the GD178 wall terminal kit, use either the 5 foot (1.5m) vent kit

GDT5 or the 10 foot (3.1m) vent kit GDT10. These kits allow for extended horizontal venting of the appliance.

When using approved Wolf Steel venting components, use only the following termination kits: WALL

TERMINAL KIT GD178, or 1/12 TO 7/12 PITCH ROOF TERMINAL KIT GDT110, 8/12 TO 12/12 ROOF

TERMINAL KIT GDT111, FLAT ROOF TERMINAL KIT GDT112.

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.

Vent terminals shall not be recessed into a wall or siding.

These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable

horizontal run is 7 feet (2.1m). The maximum allowable vertical vent length is 19 ½ feet (5.9m). 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.
