SECTION III - INSTALLATION
blower does not rub against blower housing, and that
bearing set screws are tight. If units are not set imme-
diately, cover all openings that might be exposed to the
weather.
Open the cover on the electrical control box located on
the unit. Inspect all wire terminals and wiring termina-
tions to ensure that all connections are tight.
Rotate fans monthly.
IMPORTANT: Lift and install the modules or sec-
tions of a unit separately. Flange connections pro-
vided between modules or sections are not struc-
tural and damage will occur if any attempt is made
to lift modules that have been fl anged together.
See the specifi cation sheet and submittal drawing
for unit or section weight and to determine proper
orientation for each section.
When unloading sections and/or units or moving
equipment to its fi nal location, exercise care to
avoid distortion. Lift sections and/or units only by
the lifting lugs provided and follow the procedures
as outlined below.
RIGGING AND MOUNTING DATA - DIRECT FIRED UNITS
WARNING: To insure that a proper unit lift is
made, lift unit approximately 24 inches and
verify proper center of gravity lift point. To avoid
dropping of unit, reposition lifting point if unit
is not level. Failure to properly lift unit could
result in death or serious injury or possible
equipment or property-only damage.
FOR CANADIAN INSTALLATIONS ONLY
1. All installations must conform with local building
codes, or, in the absence of local codes, with
current CAN/CGA-B149-Installation Codes For
Gas Burning Appliances and Equipment.
2. All electrical connections must be in accor-
dance with Canadian Electrical Code, Part 1,
CSA Standard C22.1.
All electrical connections must conform to the current
edition of ANSI/NFPA No. 70 National Electrical Code
and applicable local codes; in Canada, to the Cana-
dian Electrical Code, Part 1 CSA Standard C22.1. The
following recommendations are not intended to sup-
plant any requirement of federal, state, or local codes
having jurisdiction. Authorities having jurisdiction
should be consulted before installations are made. Lo-
cal codes may require additional safety controls and/or
interlocks.
All installations in airplane hangers must be in ac-
cordance with current ANSI/NFPA No. 409. All instal-
lations in public garages must be in accordance with
current NFPA No. 88A and NFPA No. 88B.
CAUTION: Do not install heating system in corrosive
or fl ammable atmospheres! Premature failure of, or
severe damage to the unit will result!
CAUTION: Heating system must not be installed in
locations where air for combustion would contain
chlorinated, halogenated or acidic vapors. If located
in such an environment, premature failure of the
unit will occur!
A. Handling the Equipment
As explained previously, the basic unit is designed for
shipping in one piece where shipping limitations allow.
Some optional accessories may require fi eld mounting.
The Direct Gas-Fired unit has been designed for
rigging and handling through the use of special lifting
lugs installed on the top and/or sides of each unit.
When unloading and setting the unit, use the lifting
lugs provided as shown in Drawing #C000539A or
move the equipment on rollers. Hooks, jacks, or chains
must not be used around the casing, main control
panel or exterior mounted controls.
During transit, unloading and setting of the unit, bolts
and nuts may have become loosened, particularly in
the pillow block ball bearing assemblies in the fan sec-
tion. It is recommended that all nuts and set screws be
tightened. Turn fan shaft by hand to make certain that
