WARNING
• Risk of fi re. Maintain specifi ed air space clearances to vent pipe and appliance.
• The vent system must be supported every 3’(0.9m) for both vertical and horizontal runs. Use support ring
assembly W010-0067 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 spaces must
not be removed.
The vent terminal may be painted with 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. Appliance should be off.
All vent measurements start at the base of the air collar of the appliance.
This appliance uses a 5” (127mm) exhaust / 8” (203.2mm) air intake vent pipe system. Refer to the
section applicable to your installation.
For safe and proper operation of the appliance follow the venting instructions 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. 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.
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.
If for any reason the vent air intake system is disassembled; reinstall per the instructions provided for the
initial installation.
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.
note:
For ease of installation, the front frame can be removed. The front frame must be
reinstalled prior to installing the nailing tabs.
important:
Horizontal vent sections: A minimum clearance of 3” (76mm) on the top outside of the enclosure and 2”
(51mm) on the sides and bottom outside of the enclosure all around the vent pipe on all horizontal runs to com-
bustibles is required. Horizontal vent sections within enclosures require a minimum clearance of 6”(152mm) at the
top of the vent pipe.
Vertical vent sections: A minimum of 1” (25mm) all around the vent pipe on all vertical runs to combustibles is
required except for clearances in appliances enclosures. Vertical vent sections within enclosures require a mini-
mum clearance of 1” (25mm) around the vent pipe.
