NOTICE
This is a gas appliance and should be
installed by a licensed electrician and/or
certified gas supplier. Service must be
performed by a qualified service
installer, service agency or the gas
supplier.
WARNING
If the information in these instructions
is not followed exactly, a fire or
explosion may result causing property
damage, personal injury, or death.
This appliance MUST NOT be installed
in any location where gasoline or
flammable vapors are likely to be
present, unless the installation is such to
eliminate the probable ignition of
gasoline or flammable vapors.
What to do if you smell gas –
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any
phone in your building.
• Immediately call your gas supplier from a neighbors
phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire
department.
Installation and service must be performed by a qualified
installer, service agency, or the gas supplier.
Warranty –
Factory warranty (shipped with unit) does not apply to
units improperly installed or improperly operated.
Experience has shown that improper installation or system
design, rather than faulty equipment, is the cause of most
operating problems.
1. Excessive water hardness causing a lime/scale build-up
in the copper tube is not the fault of the equipment and
is not covered under the manufacturer’s warranty (see
Water Treatment and Water Chemistry in the Power-fin
Installation and Operation Manual).
2. Excessive pitting and erosion on the inside of the
copper tube may be caused by too much water velocity
through the tubes and is not covered by the
manufacturer’s warranty (see Boiler Flow Rates and
Temperature Rise for flow requirements in the Power-fin
Installation and Operation Manual).
Checking equipment –
Upon receiving equipment, check for signs of shipping damage.
Pay particular attention to parts accompanying the appliance
which may show signs of being hit or otherwise being
mishandled. Verify total number of pieces shown on the
packing slip with those actually received. In case there is
damage or a shortage, immediately notify the carrier.
Do not use this appliance if any part has been under water.
The possible damage to a flooded appliance can be extensive
and present numerous safety hazards. Any appliance that has
been under water must be replaced.
WARNING
Improper installation, adjustment,
alteration, service or maintenance can cause
injury or property damage. Refer to this
manual for assistance or additional
information, consult a qualified installer,
service agency or the gas supplier.
Owner warning –
The information contained in this manual is intended for use
by qualified professional installers, service technicians, or gas
suppliers. Consult your local expert for proper installation or
service procedures.
NOTICE
Consult and follow all local Building and
Fire Regulations and other Safety Codes that
apply to this installation. Consult a local gas
utility company to authorize and inspect all
gas and flue connections.
Your conventionally vented gas appliance must have a supply of
fresh air circulating around it during burner operation for
proper gas combustion and proper venting.
WARNING
Should overheating occur or the gas supply
fail to shut off, do not turn off or disconnect
the electrical supply to the pump. Instead,
turn off the manual gas control valve to the
appliance at a location external to the
appliance.
Prevention of freezing –
Heat exchangers and headers damaged by freezing are not
covered by warranty.
See Section 7, Startup - Freeze Protection in the Power-fin
Installation and Operation for more information.

WARNING
To minimize the possibility of serious
personal injury, fire, or damage to your
appliance, never violate the following safety
rules:
1. Boilers and water heaters are heat
producing appliances. To avoid damage
or injury, do not store materials against
the appliance or the vent-air intake
system. Use proper care to avoid
unnecessary contact (especially children)
with the appliance and vent-air intake
components.
2. Never cover your appliance, lean
anything against it, store trash or debris
near it, stand on it or in any way block
the flow of fresh air to your appliance.
3. UNDER NO CIRCUMSTANCES must
flammable materials such as gasoline or
paint thinner be used or stored in the
vicinity of this appliance, vent-air intake
system or any location from which fumes
could reach the appliance or vent-air
intake system.
Codes –
The equipment shall be installed in accordance with those
installation regulations in force in the local area where the
installation is to be made. These shall be carefully followed in all
cases. Authorities having jurisdiction shall be consulted before
installations are made. In the absence of such requirements, the
installation shall conform to the latest edition of the National
Fuel Gas Code, ANSI Z223.1. Where required by the authority
having jurisdiction, the installation must conform to American
Society of Mechanical Engineers Safety Code for Controls and
Safety Devices for Automatically Fired Boilers, ASME CSD-1.
All boilers conform to the latest edition of the ASME Boiler and
Pressure Vessel Code, Section IV. Where required by the
authority having jurisdiction, the installation must comply with
the Canadian Gas Association Code, CAN/CGA-B149.1 and/or
B149.2 and/or local codes. This appliance meets the safe lighting
performance criteria with the gas manifold and control
assembly provided, as specified in the ANSI standards for gasfired units, ANSI Z21.13.
