Power vented models are designed with combustion

side access panel. Never locate these units in an area
where the flue products outlet may be directed at any
fresh air vents.See Figures 8a 8b, and 8c for
installation and servicing requirements.

VENTING
All venting installations shall be in accordance with the
latest edition of Part 7, Venting of Equipment of the
National Fuel Gas Code, ANSI Z223.1-1999, or
applicable provisions of local building codes.
Natural venting models are equipped with a vent cap
designed for natural venting. Air for combustion enters
at the base of the vent through a protective grille, and the
design of the vent cap is such that the products of
combustion are discharged at the upper section of the
cap. The cap is shipped in a separate carton. It should
be fastened in position as shown in Figure 7 and should
not be altered in any way.
The venting is an integral part of
the unit and must not be altered in the field. If
altered, excessive carbon monoxide could be
produced.

*These Surfaces (indicated with an asterisk in figures 8a & 8b)
MUST be flush and sealed at all times to ensure the proper
discharge of flue products from the unit.
These discharge flanges are equipped with special gasketing,
which must create an air tight seal connection around the louvers
of the access panel.
Secure in place the access door to the discharge adaptor using the
two screws and neoprene washers, then tighten the grip
latches (see service access panel removal section).
