Connecting The Power Supply - Vesta VRC-100 Installation Manual

Connecting the Power Supply

Improperly connecting the power supply can result in
electrical shock and electrocution. Follow all applicable
electrical codes of the local authority having jurisdiction. In
Warning
the absence of such requirements, follow the latest edition of
the National Electrical Code (NFPA 70) in the USA or the latest
edition of CSA C22.1 Canadian Electrical Code Part 1 in Canada.
Connecting the power supply should be performed only by a
licensed professional.

Installation Manual
When connecting the power supply, follow these guidelines:
•
Do not connect the electric supply until all plumbing and gas
piping is complete and the boiler has been filled with water.
•
Do not connect the boiler to a 220–240V AC power supply.
Doing so will damage the boiler and void the warranty.
•
All boilers come with a factory-installed, 3-pronged (grounded)
plug. The boiler can be plugged into any grounded electrical
outlet nearby, as it requires only 5A. It is not necessary to run a
dedicated electrical line to the boiler.
•
If local codes require the boiler to be wired directly, remove
and discard the factory- installed plug. Install a power switch
between the breaker and the boiler to facilitate end-user
maintenance and servicing. Connect the boiler to a 110–120V
AC at 60 Hz with a maximum of 5A rating electrical supply.
•
The boiler must be electrically grounded. If using the power
plug, ensure that the electrical outlet you connect the boiler
to is properly grounded. If wiring the boiler directly to a power
supply, do not attach the ground wire to either the gas or the
water piping as plastic pipe or dielectric unions may prevent
proper grounding.
•
We recommend using a surge protector to protect the boiler
from power surges.
•
If there is a power failure in cold weather areas, the freeze
prevention system in the boiler will not operate and may result
in freezing of the heat exchanger. In cold weather areas where
power failures are common, you must completely drain the
boiler to prevent damage if the power is expected to be of
for any extended period of time. A battery back-up (available
at most computer retailers) may be used to supply hot water
during periods of power outages. Damage caused by freezing is
not covered under warranty.
