SAFETY CONSIDERATIONS

Installing and servicing heating equipment can be hazardous due to
gas and electrical components. Only trained and qualified person-
nel should install, repair, or service heating equipment. Untrained
personnel can perform basic maintenance functions such as clean-
ing and replacing air filters. All other operations must be per-
formed by trained service personnel. When working on heating
equipment, observe precautions in literature, on tags, and on labels
attached to or shipped with unit and other safety precautions that
may apply.
Follow all safety codes. In the United States, follow all safety
codes including the National Fuel Gas Code (NFGC) NFPA
54-1999/ANSI Z223.1-1999 and the Installation Standards, Warm
Air Heating and Air Conditioning Systems (NFPA 90B)
ANSI/NFPA 90B. In Canada, refer to the current edition of the
CAN/CGA-B149.1- and .2-M00 National Standard of Canada,
Natural Gas and Propane Installation Codes (NSCNGPIC). Wear
safety glasses and work gloves. Have a fire extinguisher available
during start-up and adjustment procedures and service calls.
Recognize safety information. This is the safety-alert symbol
When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury.
Understand these signal words DANGER, WARNING, CAU-
TION, and NOTE. These words are used with the safety-alert
symbol. DANGER identifies the most serious hazards which will
result in severe personal injury or death. WARNING signifies
hazards which could result in personal injury or death. CAUTION

The model 350MAV, Series F furnaces are available in sizes
40,000 through 138,000 Btuh input capacities.
The 350MAV Multipoise Condensing Gas-Fired Furnaces are
C.S.A. (A.G.A. and C.G.A.) certified for natural and propane gases
and for installation in alcoves, attics, basements, closets, utility
rooms, crawlspaces, and garages. The furnace is factory-shipped
for use with natural gas. A C.S.A. (A.G.A. and C.G.A.) listed gas
conversion kit is required to convert furnace for use with propane
gas. The 350MAV 040 through 120 size units are C.S.A. (A.G.A.
and C.G.A.) approved for use in manufactured (mobile) homes
when factory accessory conversion kit is used. The 140 size unit is
NOT approved for use in manufactured (mobile) homes. These
furnaces are suitable for installation in a residence built on site or
a manufactured residence completed at final site. The design of
this furnace line is NOT C.S.A (A.G.A and C.G.A.) certified for
installation in recreation vehicles or outdoors.
These furnaces SHALL NOT be installed directly on carpeting,
tile, or any other combustible material other than wood flooring. In
downflow installations, factory accessory floor base MUST be
used when installed on combustible materials and wood flooring.
Special base is not required when this furnace is installed on
manufacturer's Coil Assembly Part No. CD5 or CK5, or when Coil
Box Part No. KCAKC is used.
These furnaces are shipped with the following materials to assist in
proper furnace installation. These materials are shipped in the main
blower compartment.

These furnaces are shipped with the drain and pressure tubes
connected for UPFLOW applications. Minor modifications are
required when used in DOWNFLOW, HORIZONTAL RIGHT, or
. HORIZONTAL LEFT (supply-air discharge direction) applica-
tions as shown in Fig. 1. See details in Applications section.
This furnace must be installed with a direct-vent (combustion air
and flue) system and a factory accessory termination kit. In a
direct-vent system, all air for combustion is taken directly from the
outside atmosphere and all flue products are discharged to the
outside atmosphere. See furnace and factory accessory termination
kit instructions for proper installation.
