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 Indirect 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 #C000539 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 section. It is
recommended that all nuts and set screws be tightened.
Turn fan shaft by hand to make certain that blower does
not rub against blower housing, and that bearing set
screws are tight.
If units are not set immediately, cover all openings that
might be exposed to the weather.
Rotate fans monthly.
IMPORTANT: Lift and install the modules or sections
of a unit separately. Flange connections provided
between modules or sections are not structural
and damage will occur if any attempt is made to lift
modules that have 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 – INDIRECT 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.
