Vent system
Vent/chimney sizing
1. Follow all local codes when sizing the vent and chimney.
2. Refer to the appliance manufacturer’s manual, when available, for venting
recommendations.
Prepare vent/chimney
1. Secure all metal vent joints with screws, following the vent manufacturer’s
instructions. Seal all joints in the vent system and chimney. Repair ma-
sonry chimney lining and repair all mortar joints as needed.
2. Where draft fluctuations are likely, install a double-acting barometric draft
regulator in the vent piping. (The damper must be located in the same
space as the appliance.) Install a manual reset spill switch in the top of
the draft regulator outlet. Wire the switch into the appliance limit circuit to
shut off the appliance/burner if sustained downdraft should occur. Refer
to the appliance manufacturer’s instruction manual for recommendations
regarding the need for a barometric draft regulator.
3. Provide support for the vent piping. Do not rest the weight of any of the
vent piping on the appliance flue outlet.
Clearances
Check codes, standards and the equipment
manual
• Verify that the burner/appliance will maintain all clearances to combustible
walls or floor and all clearances required for service/maintenance as
required in the appliance manual and applicable codes.
Inspect, repair and/or replace vent
system
Do not install this burner unless you have verified
the entire vent system and the appliance are in good
condition and comply with all applicable codes.
And . . .
The vent and chimney must be sized and con-
structed in accordance with all applicable codes. If
intended for use with an oil burner as well, the vent
system must comply with relevant codes for both
gas and oil firing.
The vent system must not be pressurized unless
the vent piping and vent system are designed ac-
cordingly. The vent must provide draft at all times
(negative pressure in vent).
Do not install or use an existing manual damper in
the vent connector or vent.
Do not connect the appliance vent connector to a
chimney or vent serving a fireplace, incinerator or
solid-fuel-burning apparatus.
In a cold climate, do not vent into a masonry chimney
that has one or more sides exposed to the outside.
Install a listed stainless steel liner to vent the flue
products.
A defective vent system could result in severe per-
sonal injury, death or substantial property damage.
