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 masonry
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.

system
Do not install this burner unless you have veri-
fied 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 constructed 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 accordingly. The vent
must provide draft at all times (negative pressure in vent).
Seal the appliance: Seal all flue-gas containing joints. Seal
all connections to the vent piping or breeching.
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 personal
injury, death or substantial property damage.
