WARNING
!
• Risk of fi re! Maintain specifi ed air space clearances to vent pipe and appliance.
• The vent system must be supported every 3ft (0.9m) for both vertical and horizontal runs. Use supports or
equivalent non-combustible strapping to maintain the required clearance from combustibles. Spacers are attached
to the inner pipe at pre-determined 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 APPLIANCE USES A 8" (203.2mm) EXHAUST / 11" (279mm) AIR INTAKE VENT PIPE SYSTEM.
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.Although not a requirement, it is recommended for vent lengths that
pass through unheated spaces (attics, garages, crawl spaces) be insulated with the insulation wrapped in a protective
sleeve to minimize condensation.
The vent terminal may be painted with a high temperature paint to match exterior colours. Use an outdoor paint
suitable for 400°F (200°C). Application and performance of paint is the consumer's responsibility. Spot testing is
recommended.
note:
If for any reason the vent air intake system is disassembled, re-install per the instructions provided for the
initial installation.
note:
This appliance must be installed with a continuous connection of exhaust and air intake vent pipes. Utilizing
alternate constructions such as a chimney as part of the vent system is not permitted.
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 fl exible components with the following
termination kits: wall terminal kit GD822R, or 1/12 to 7/12 pitch roof terminal kit GD810, 8/12 to 12/12 roof terminal kit
GD811 or fl at roof terminal kit GD812. With fl exible venting, in conjunction with the various terminations, use either the 5
foot (1.5m) vent kit GD820 or the 10 foot (3m) vent kit GD830.
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.
The minimum allowable vertical vent length is 3 feet (0.9m) maximum allowable vertical vent length is 40 feet (12m).
The maximum number of allowable 8" (203mm) vent connections is three horizontally or vertically (excluding the
appliance and the air terminal connections).
When venting, the horizontal run must be kept to a minimum of 36" (914mm) or a maximum of 20 feet (6m). If a 20
foot (6m) horizontal run is required, the appliance must have a minimum vertical rise immediately off the appliance of
57" (1448mm). When terminating vertically, the vertical rise is a minimum 36" (914mm) and a maximum 40 feet (12m)
above the appliance.
For optimum performance, it is recommended that all horizontal runs have a minimum 1/4" (6mm) rise
per foot/meter. Provide a means for visually checking the vent connection to the appliance after the
appliance is installed. Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows.
Keep it pulled tight. A 3/4" (19mm) air gap between the inner and outer liner all around is required for safe
operation. Use a fi restop when penetrating interior walls, fl oor or ceiling.
