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 location
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.
Field Wiring

Optional Gas Piping
