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.
