WARNING
Improperly connecting the power supply can result in electrical
shock and electrocution Follow all applicable electrical codes

of the local authority having jurisdiction In 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.
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 the VC boilers come with a factory installed VESTA - ,
3 pronged grounded plug The boiler can be plugged into any - ( ) .
grounded electrical outlet nearby as it requires only 2 Amps 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 2A.
●
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 will be off 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.
