Installation shall be in accordance with the
requirements of authorities having jurisdiction and
ANSI Z2231/NFPA 54 or CSA B149.1. Heaters
must be provided with sufficient combustion air and
shall not be located in an area where a negative
pressure will be created that will starve the burner
of combustion air. Flue outlet pressure must not
exceed maximum over fire pressure shown on the
nameplate.
Do not connect the vent to any portion of
mechanical draft systems that are under positive
pressure. Do not install dampers or other
restrictive devices in the flue vent pipe.
Vent terminations shall be in accordance with the
requirements of the authorities having jurisdiction.
The vent shall be installed in such a manner that access to the appliance or unit rating plate is not
obstructed.

A vertical chimney must be certified “A” or “L” or equivalent type on units without draft hoods. Type
“B” vent is acceptable on units with Engineered Air draft hoods. The vent size shall be selected
from appropriate approved Vent Table.
Note: Oil fired heaters MUST use “A” vent.
2.
A vent connector shall be of approved material and installation. It shall have a minimum clearance
of 9" (229 mm) to combustible material. All horizontal portions of the venting system shall be
supported to prevent sagging. All horizontal runs shall have a minimum rise of 2% in the direction
of discharge. Horizontal vents shall be properly supported.

the vent termination securely to the unit casing using #8 X 5/8” (minimum) sheet metal screws with
washers at all holes provided. Horizontal clearance to obstructions is 24” (600mm) for the standard vent
termination. Flue gases may discolour or damage adjacent surfaces. Vent terminations must not be under
structures or building overhangs.
