6.12 Electrical connections
All electrical wiring to the boiler (including grounding) must conform to local electrical codes and/or
to the National Electrical Code, ANS/NFPA No. 70 – latest edition, or to the Canadian Electrical
Code, C22.1 - Part 1.
6.12.1 Power management, quality and electrical protection
In areas of unreliable power, appropriate surge protectors and or power conditioning equipment
should be installed in power supply wiring circuits.
Note
The IBC boiler (like any modern appliance that contains electronic equipment) must
have a "clean" power supply, and is susceptible to power surges and spikes,
lightning strikes and other forms of severe electrical "noise". Power conditioning
equipment (surge protectors) may be required in areas where power quality is
suspect.
In temporary or manual operation, for example in new construction heating, use a construction
thermostat or jumper with an in-line switch for on/off management of the boiler. Do not turn off the
heat by removing power to the boiler as this interrupts the pump post-purge.
6.12.2 240VAC line-voltage hook-up
Line-voltage wiring is done within the field-wiring box (see
the boiler to the grid power using a separate, fused circuit and on/off switch within sight of the
boiler. Use appropriately-sized wire in conduit or metallic sheath properly anchored to the boiler
case for mains supply and pump circuits.
