Optional power supply
Advantus
boilers supplied at 460/3/60 voltage, differ from the standard unit per the following:
CAUTION
While working with 460V circuits, it is imperative that extra precautions be taken
Ensure that lock-out/tag-out procedures are strictly enforced
Only properly trained and authorized personnel should be permitted to work on live electrical circuits
All electrical workers should be trained in electrical rescue techniques and CPR.
Each unit has a back mounted 500VA transformer to supply the single leg 115V necessary for the ignition circuit, which is factory mounted.
The boiler itself is a single point power connection. A 460V/3/60 variable frequency drive replaces the standard VFD, and the combustion
blower fan has been configured to operate at 460/3/60V (using the standard fan). Part numbers as well as FLA and MOCP information
is below.

The combustion air fan motor operates on 230 VAC, 3 phase, 60Hz on models AV800-4000. Three phase voltage is generated by the
VFD and supplied directly to the fan motor on models 800-4000. Refer to Table 9 for appropriate supply voltage to the appliance. The
appliance, when installed, must be electrically grounded in accordance with the requirements of the authority having jurisdiction or in the
absence of such requirements, with the latest edition of the National Electrical Code ANSI/NFPA No. 70. When the unit is installed in
Canada, it must conform to the Canadian Electrical Code, C22.1, Part 1 and/or local Electrical Codes.
All wiring between the appliance and field installed devices shall be made with wire having minimum 220°F (105°C) rating.
Line voltage wire external to the appliance must be enclosed in approved conduit or approved metal clad cable.
The pump must run continuously when appliance is firing.
To avoid serious damage,
DO NOT ENERGIZE
the appliance until the system is full of water. Ensure that all air is removed
from the heat exchanger pump housing and piping before beginning initial operation. Serious damage may result if the appliance
is operated prior to purging of all air.
Provide the appliance with proper overload protection.
