Entry Locations
Manufacturer recommends that electrical service and gas

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
Recommended Gas and Electric Supply Entry Locations
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.
Gas Connections
If this unit is equipped with an indirect gas-fired furnace,
connection to an appropriate gas supply line will be required.
For complete information on installation procedures for the
optional gas furnace, refer to the PVF/PVG Indirect Gas-Fired
Heat Module Installation, Operation, and Maintenance
