Fig. 2 -- Dimensional Drawing
The 355AAV Multipoise Condensing Gas--Fired Furnaces are CSA
(formerly AGA and CGA) design--certified for natural and propane
gases (see furnace rating plate) and for installation in alcoves,
attics, basements, closets, utility rooms, crawlspaces, and garages.
The furnace is factory--shipped for use with natural gas. A CSA
listed gas conversion kit is required to convert furnace for use with
propane gas.
See Fig. 3 for required clearances to combustibles.
Maintain a 1--in. (25 mm) clearance from combustible materials to
supply air ductwork for a distance of 36 inches (914.4 mm)
horizontally from the furnace. See NFPA 90B or local code for
further requirements.
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 or when Manufacturer’s Coil Box
is used. These furnaces are suitable for installation in a structure
built on site or a manufactured building completed at final site. The
design of this furnace line is NOT CSA design--certified for
installation in recreation vehicles, manufactured (mobile) homes or
outdoors.
This furnace is designed for continuous return--air minimum
temperature of 60_F (16_C) db or intermittent operation down to
55_F (13_C) db such as when used with a night setback
thermostat. Return--air temperature must not exceed 80_F (27_C)
db. Failure to follow these return air limits may affect reliability of
heat exchangers, motors and controls. (See Fig. 4.)
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)
applications as shown in Fig. 1. See details in Applications section.
Install this furnace only in a location and position as specified in
LOCATION and INSTALLATION sections of these instructions.
Combustion products must be discharged outdoors. Connect this
furnace to an approved vent system only, as specified in the
Combustion Air and Vent piping sections of these instructions.
Never test for gas leaks with an open flame. Use a commercially
available soap solution made specifically for detection of leaks to
check all connections as specified in the GAS PIPING section of
these instructions.
Always install the furnace to operate within the furnace’s intended
rise range with a duct system which has an external static pressure
within the allowable range as specified in the SET
TEMPERATURE RISE section of these instructions.
