WARNING
!
• Risk of fi re. Maintain specifi ed air space clearances to vent pipe and appliance.
• If venting is included with spacers, the vent system must be supported every 3 feet (0.9m) for both vertical
and horizontal runs. Use supports or equivalent combustibles. Use Wolf Steel Ltd. support ring assembly
W010-0370 or equivalent non-combustible strapping to maintain the minimum clearance to combustibles
for both vertical and horizontal runs. Spacers are attached to the inner pipe at predetermined intervals to
maintain an even air gap to the outer pipe. This gap is required for safe operation. A spacer is required at the
start, middle and end of each elbow to ensure this gap is maintained. These spacers must not be removed.
This appliane uses a 3" (76.2mm) exhaust / 5" (127mm) air intake vent pipe system. Refer to the section
For safe and proper operation of the appliance follow the venting instruction exactly. Deviation from the minimum
vertical vent length can create diffi culty in burner start-up and/or carboning. Under extreme vent confi gurations,
allow several minutes (5-15) for the fl ame to stabilize after ignition. Provide a means for visually checking the vent
connection to the appliance after the appliance is installed. Use a fi restop, vent pipe shield or attic insulation shield
when penetrating interior walls, fl oor or ceiling.
NOTE: If for any reason the vent air intake system is disassembled; reinstall per the instructions
provided for the initial installation.
2.1

cold climate

For horizontal and vertical vent runs that pass through unheated spaces (attics, garages, crawl spaces) it is
recommended they be insulated with the insulation wrapped in a protective sleeve to minimize condensation.
Vent lengths terminating vertically should be kept to short lengths (maximum 5ft / 1.5m) in areas with colder
climates, especially in installations where the majority of the vent length is to be installed outside the building
envelope (such as in the attic).
2.2

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, fl at 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.
