INTRODUCTION
All installations must conform to the requirements
of the authority having jurisdiction. Such applicable
requirements take precedence over the general
instructions of this manual.
Where required by the authority having jurisdiction, the installation must conform to the American
Society of Mechanical Engineers Safety Code for
Controls and Safety Devices for Automatically
Fired Boilers, ANSI/ASME No. CSD-1.
LOCATE BOILERS in front of nal position before
removing crate. Provide a level solid base as near
the chimney as possible, and centrally located
with respect to the heat distribution system as
practical.
WARNING
BOILER MAY NOT BE INSTALLED ON
COMBUSTIBLE FLOORING.
Allow 24 inches in the front and top for servicing and
cleaning, or removing tankless water heating coil.
When installed in a utility room, the door should
be wide enough to allow the largest boiler part to
enter, or to permit replacement of another appliance such as a water heater.
FOR INSTALLATION ON NON-COMBUSTIBLE
FLOORS ONLY. The boiler must not be installed
on carpeting or vinyl ooring. Minimum clearances
to combustible construction are:
TOP .............................................24 IN.
FRONT ........................................24 IN.
FLUE CONNECTOR .....................9 IN.
REAR ............................................6 IN.
SIDES .........................................12 IN.
NOTE: Clearance for access should exceed
fore protection clearance.
REMOVE CRATE and plastic protective wrapper
and inspect for damage. All equipment is carefully
manufactured, inspected and packaged by experienced workers. Our responsibility ceases upon
delivery of the crated boiler to the carrier in good
condition. Any claims for damage or shortage in
shipment must be led immediately against the
carrier by the cosigner. Move boiler to permanent
position by sliding or walking.

1. When a boiler is located in an unconned
space in a building of conventional construction
frame, masonry or metal, inltration normally
is adequate to provide air for combustion and
ventilation. However, in any building which
has been altered to conserve energy or to
minimize inltration, the boiler area should
be considered as a CONFINED SPACE. If
there is any doubt, install air supply provisions
for combustion and ventilation in accordance
with section 5.3, Air for Combustion and Ventila-
tion, of the latest revision of the NFPA 54 code,
the recommendations that follow, or applicable
provisions of the local building codes.
2. When a boiler is installed in an unconned space,
in a building of unusually tight construction, air
for combustion and room ventilation must be
obtained from outdoors or from spaces freely
communicating with the outdoors. A permanent
opening or openings having a total free area
