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.
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.
Appliances equipped with a gas conversion burner are
treated as fan-assisted appliances.
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 pres-
sure 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.
Chimney, chimney liner & exhaust vent system
must be inspected and comply with all applicable
local and national codes including National Fuel
Gas Code (NFPA54 / ANSI Z223.1), ANSI Z21.8 or
CAN/CGA B/49 Canada.
A defective vent system could result in severe personal
injury, death or substantial property damage.
Vent/chimney sizing
• Follow all local codes when sizing the vent and chimney
• Refer to the appliance manufacturer’s manual, when available,
for venting recommendations.
Prepare vent/chimney
• 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.
• Install a double-acting barometric draft regulator to the vent
piping. (The damper must be located in the same space as
the appliance.) Install a manual reset spill switch (blocked vent
switch) per spill switch manufacturer’s instructions. Wire the
switch into the appliance limit circuit to shut off the appliance/
burner if sustained downdraft or flue blockage should occur.
• For through-wall vented appliances, follow the venting recom-
mendations provided by the appliance and power venter (if
used) manufacturers.
• Provide support for the vent piping. Do not rest the weight of
any of the vent piping on the appliance flue outlet.
