14.5 Pre-Startup Checklist
Before starting the unit, check for adequate electrical service, confirm if any external control wiring connections exist,
confirm heater filled with water, check all plumbing connections for leaks, and ensure the condensate trap is installed
properly and that the gas supply meets the product rating decal requirements as follows:
CHECK ELECTRICAL SERVICE
1. Start by checking the electrical service. The standard electrical service required is a 120 volt, single phase, 60
Hertz power supply that is also electrically grounded. See the appliance rating decal on the front of the unit for
the electrical service requirements for your specific product.
2. Next, shut off the electrical service to the unit and turn the boiler power switch to the OFF position.
3. Remove the large front cover in order to gain access to the burner controls and adjustments as well as the main
control enclosure.
Locate the document packet containing the control circuit fuse and fuse cap. A wiring diagram is also in the
document packet.
Remove the fuse and fuse cap from the packet and install them into the fuse holder on the front of the panel.
Check the back of the digital control display board on the hinged panel to see if a 2-wire, RS-485
communication cable is connected. These wires must be removed to isolate the boiler from the Building
