4 − Remove the flue box/combustion air inducer
assembly, ensuring that the gasket is not
damaged. If the gasket is damaged, replace it.
5 − Use a 1/4" socket to remove the three screws
which secure the combustion air inducer to the
flue box.
Remove the inducer and gasket from the flue box
ensuring that the gasket is not damaged. If the
gasket is damaged, replace it.
6 − Use the template provided in the back of this
manual to mark new hole locations. Use a 7/32"
drill bit to drill holes in flue box.
7 − Place the gasket between the combustion air
inducer and the flue box. Rotate both the inducer
and the gasket 90° to the desired position.
Reinsert and tighten the three inducer securing
screws
(#8 −16 X 1/2" HWHSMS).
8 − Place the gasket between the flue box and the
vest panel. Position the flue box/combustion air
inducer assembly on the vest panel. Fasten the
flue box to the vest panel using the flue box
securing screws (#10 −16 X 5/8" HWHSMS) and a
5/16" driver.

Venting
NOTE
− The
vent is a passageway, vertical or nearly
so, used to convey flue gases from an appliance, or its
vent connector, to the outside atmosphere. The vent
connector is the pipe or duct that connects a fuel-gas
burning appliance to a vent or chimney.
NOTE
− Loc
al codes may supersede any of these
provisions.
GENERAL RECOMMENDATION AND
REQUIREMENTS
SEP unit heaters must be vented in compliance with
the latest edition of the National Fuel Gas Code (NFPA
54 / ANSI Z223.1) in the USA and with CSA-B149.1
codes in Canada, as well as applicable provisions of
local building codes, and the following instructions.
A sheet metal flue transition is supplied with this
certified unit. It must not be modified or altered and
must be installed on the outlet of the combustion
air inducer assembly prior to the installation of the
vent connector. Failure to comply with this
requirement will void the certification of the unit by
the approval agencies.
A single-wall vent connector may be used in all
applications between the furnace and the vertical vent
pipe.
A single −wall vent pipe used as a vent connector or as
a vertical vent, must have all seams and joints sealed
with pressure-sensitive aluminum tape or silicone
rubber sealant. Aluminum tape must meet the
provisions of SMACNA AFTS −100−73 Standards. The
aluminum tape must have a temperature rating of
400°F (204°C).
Silicone rubber sealant must have a temperature rating
of 482°F (250°C), i.e., Dow Corning RTV −736 or
equivalent.
All joints must be secured with at least two corrosion
resistant screws. All joints must be checked for gas
tightness after installation. Single-wall vent pipe used
as vertical vent must not pass through any attic, interior
wall, concealed space, or floor.
