RIG AND PLACE UNIT
Inspect unit for transportation damage. File any claim with
transportation agency. Keep unit upright and do not drop. Spreader
bars are not required if top crating is left on unit. Rollers may be
used to move unit across the roof. Level the unit by using unit
frame.
Lifting holes are provided in base rails as shown in Figure 31. All
panels must be in place when rigging.
The unit cannot be placed on the curb with a fork lift or other lifting
device through the fork lift openings. Doing so would interfere with
placement on the roof curb.
Maintain clearance around and above the unit to provide minimum
distance from combustible materials, proper air flow, and service
access.
Do not install unit in an indoor location. Do not locate unit air inlets
near exhaust vents or other sources of contaminated air.
Be sure that unit is installed such that snow will not block the
combustion intake or flue outlet.
Unit may be installed directly on wood flooring or on Class A, B, or
C roof covering material when roof curb is used.
Although unit is weatherproof, guard against water from higher
level runoff and overhangs.
Exhaust vent terminal must have a minimum horizontal clearance
of 4 ft. from electric and gas meters, gas regulators, and gas relief
equipment. Minimum distance between unit and other electrically
live parts is 48 inches.
Flue gases can deteriorate building materials. Orient unit such
that flue gas will not affect building materials.
Adequate combustion and ventilation air space must be provided
for proper operation of this equipment.
After unit is in position, remove rigging skids and shipping
materials.
