Electrical Connections - PENSOTTI PNCC-32N Instruction Manual

3.7 Electrical connections

3.7.1 General warnings
Follow the electrical code requirements 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 U.S.
or the latest edition of CGA C22.1 Canadian Electrical Code – Part 1 in Canada.
3.7.2 Electric Wiring: Ground and Surges
All units come with factory installed 3-pronged (grounded) plug end. The boiler must be plugged
into a dedicated electrical outlet and circuit. The use of extension cords are prohibited.
If the local jurisdiction requires the unit to be wired directly, remove and discard the factory installed plug. An
ON/OFF switch controlling the main power between the breaker and the Boiler should be provided to facilitate
end-user maintenance and servicing. This should be done by a qualified electrician.
The boiler must be electrically grounded. Ensure the electrical receptacle, in which the boiler will be plugged
into, is properly grounded; if wiring directly, do not attach the ground wire to either the gas or the water
piping as plastic pipe or dielectric unions may isolate the boiler electrically.
The use of a surge protector, surge capacitor, line conditioner or equivalent is recommended to protect the
appliance from power surges.
If a generator is to be used as "backup" power a line conditioner must be installed to protect the appliance from
erratic voltage and Hz.
If the boiler is to be installed in a structure utilizing a emergency stand-by generator, the installation of a surge
capacitor, surge protector, line conditioner or equivalent is required.
If the boiler is to be installed in a structure where frequent power outages are experienced the installation of a
surge capacitor, surge protector, line conditioner or equivalent is required.
Do not energize electric power to the unit until all plumbing and gas piping is complete and the boiler has been
filled with water and all air has been properly purged for the boiler and heating system.
The electrical supply required by the boiler is 120VAC at 60Hz with a maximum 4A rating with proper
grounding. Protection must be in place to prevent the Boiler from being exposed to voltage in excess of
130VAC Max or 95VAC Min.
Damage caused by excessive voltage is not covered under warranty.
DO NOT connect 220-240VAC to this PENSOTTI Boiler. This will damage the boiler and void the warranty.
Do not disconnect the power supply when the unit is in normal operation.
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 unit to prevent damage if the power will be off for any extended period of
time.
Damage caused by freezing is not covered under warranty.
CAUTION : Label all wires prior to disconnection when servicing controls. W iring errors can cause improper
and dangerous operation. Verify proper operation after servicing.
The connection to the main power supply must be carried out by professionally qualified electrical personnel,
registered in accordance with current legislation and local authorities.
