INSTALLATION
Rail Mounting and Layout
1. The units may be installed on rails provided and installed by others.
Ensure that rails are designed to handle the weight of the unit and
provide proper load distribution on building supports.
2. Make sure that rail positioning does not interfere with the openings
on the unit.
3. Rails should run the width of the unit and extend beyond the unit a
minimum of 12 inches on each side.
4. Set unit on rails.
Recommended Electrical and Gas
Supply Entry Locations
Manufacturer recommends that electrical service and gas supply be
brought into the cabinet through the end wall, as shown below. There
are three penetrations into the cabinet that are required; one for high
voltage supply wiring, one for low voltage control wiring, and one for
either gas supply or high voltage supply wiring for an electric heater.
Alternate Supply Entry Locations
Each installation is unique and as a result, alternate entry locations may be field-located. Before using
any alternate entry location, verify the suitability of the location and ensure the use of an alternate loca-
tion does not interfere with unit wiring, components or functionality.
WARNING
Never drill holes in the roof of the unit! There is high voltage wiring located between the inner and outer roof
panels. Damage to the wiring could cause severe bodily harm or death.
