WIRING THE GAS HEAT DEVICE
It is the installer's responsibility to wire this device, if
the single point power connection was not purchased.
Panel locations and sizes vary based upon the AHU's
size and burner configurations. Burner voltage is se-
lected to match the primary AHU voltage. Modulation
control voltage 2-10 VDC is standard.
Electrical penetrations can come through the floor or
side wall panels. Drill and properly seal any penetra-
tions to keep out moisture. Refer to the service manual
for more information.
Make power connections per the wiring diagrams pro-
vided on the inside of the burner control panel. Refer to
the Air Handling Units - Operation and Maintenance
Manual (Form 102.20-OM2) for more information.
