WARNING
Carefully read all instructions before installing
boiler. Failure to follow all instructions in proper
order can cause personal injury or death.
A. Inspect shipment carefully for signs of damage.
Any claim for damage or shortage in shipment
must be filed immediately against carrier by
consignee. No claims for variances or shortages
will be allowed by Boiler Manufacturer, unless
presented within sixty (60) days after receipt of
equipment.
B. Safe, reliable operation of this boiler depends
upon installation by a professional heating
contractor in strict accordance with this manual
and the requirements of the authority having
jurisdiction. In absence of such requirements,
installation must conform to National Fuel Gas
Code, ANSI Z223.1/NFPA 54. In Canada, follow
CAN/CSA B149.1 (Natural Gas and Propane
Installation Code). Where required by the
authority having jurisdiction, this installation must
conform to the Standard for Controls and Safety
Devices for Automatically Fired Boilers (ANSI/
ASME CSD-1).
C. Read Section 6 "Venting" to verify that the
maximum exhaust pipe length will not be
exceeded in the planned installation. Also
verify that the vent terminal can be located in
accordance with Section 6.
D. If the boiler is to be direct vented, make sure that
the correct kit shown in Table 2.2 is on hand for
the model boiler being installed. Also consult
Appendix A (Direct Venting) to confirm that the
maximum intake pipe length will not be exceeded
and that the intake terminal may be located as
required on the outside of the building.
E. Make sure that the boiler is correctly sized:
• For heating systems employing convection
radiation (baseboard or radiators), use an
industry accepted sizing method such as
the I=B=R Guide RHH published by the Air-
Conditioning, Heating and Refrigeration Institute
(AHRI).
• For new radiant heating systems, refer to the
radiant tubing manufacturer's boiler sizing
guidelines.
• For system which includes an indirect water
heater, make sure the boiler has the output
called for by the indirect water heater
manufacturer's instructions.

Installation, Operating & Service Manual
PVCG-C
F.
Make sure the boiler is configured for the correct
gas (Natural or LP).
G.
For high altitude installation above 2,000 ft., see
Appendix B.
NOTICE: This boiler is not approved for use in
Canada above 2000ft.
H. This boiler is equipped with a listed low water
cut-off (LWCO). Unless the authority having
jurisdiction requires a manual reset LWCO, it
should not be necessary to install an external
LWCO.
• Do not attempt to operate a natural gas boiler
on LP, or an LP boiler on natural gas without
first converting it using a kit provided by
the factory.
• Failure to properly convert this boiler for
the fuel being used will result in operation
of the boiler at high Carbon Monoxide (CO)
levels and/or other unsafe conditions, resulting
in personal injury or loss of life. Improper
conversion may also result in unreliable
operation and severe property damage.
• Before attempting to operate this boiler at
altitudes above 2000ft, follow the instructions
shown in Appendix B of this manual.
