IMPORTANT: Read and understand the following
instructions COMPLETELY before installing.

!

WARNING

Installations of boilers and venting shall be done
only by qualied expert and in accordance with this
manual. Installing or venting a boiler or any other
gas appliance with improper methods or materials
could result in serious injury or death due to re

carbon monoxide which is odorless and invisible.

!

WARNING

Keep boiler area clear and free from combustible
materials, gasoline and other ammable vapors and
liquids.

Do not obstruct air openings to boiler room.

Modication, substitution or elimination of factory
equipped, supplied or specied components could
result in personal injury or the loss of life.

SAFETY SYMBOLS

The following dened symbols are used throughout this
manual to notify reader of potential hazards of varying risk
levels.

LOCATING THE BOILER

• Installations shall 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 boiler in front of nal position before removing
crate.

• Provide level solid base as near chimney as possible
and centrally located with respect to heat distribution
system as practical.

• Allow 24 inches in front, top and right hand side for
servicing and cleaning, or removing tankless water
heating coil.

• Recommend 24 inches be allowed in back of boiler for
convenience when skimming hole is used.

• When installed in a utility room, the door should be
wide enough to allow largest boiler part to enter, or to
permit replacement of another appliance such as water
heater.

• Install boiler such that oil ignition system components
are protected from water (dripping, spraying, rain etc.)
during appliance operation and service.

FOR INSTALLATION ON NON-COMBUSTIBLE FLOORS ONLY
Boiler must not be installed on carpeting or vinyl ooring.
Minimum clearances to combustible construction are:

Figure #2 - Minimum Clearances To Combustible
Construction (as seen from above)

WARNING

Fire hazard. Do not install boiler on combustible
ooring or carpeting. Failure to follow these
instructions could result in death or serious injury.

1.

Ventilation of boiler room must be adequate enough to
provide sufcient air to properly support combustion,
venting and maintain safe ambient temperatures under
normal operating conditions.

2.

When the boiler is located in an unconned space in a
building of conventional construction frame, masonry
or metal, inltration normally is adequate to provide
air for combustion and ventilation. However, in any
building which has been altered to conserve energy
or to minimize inltration, the boiler area should
be considered as a conned space. If there is any
doubt, install air supply provisions for combustion
and ventilation in accordance with Chapter 5, Air for
Combustion and Ventilation, of NFPA 31, Standard
for the Installation of Oil Burning Equipment. The
recommendations that follow, or applicable provisions
of the local building codes.

3.

When the boiler is installed in an unconned 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 of not less than 1 square inch
per 5,000 BTU per hour of total input rating of all
appliances shall be provided. Ducts may be used to
convey make-up air from the outdoors and shall have
the same cross-sectional area of the openings to which
they are connected.

4.

When air for combustion and room ventilation is from
inside buildings, the conned space shall be provided
with two permanent openings, one starting 12 inches
from the top and one 12 inches from the bottom of the
enclosed space. Each opening shall have a minimum
free area of 1 square inch per 1,000 BTU per hour of
the total input rating of all appliances in the enclosed
space, but must not be less than 100 square inches.
These openings must freely communicate with the
interior areas having adequate inltration from the
outside. See Figure #3.

VENTILATION AND COMBUSTION AIR

5.

When the boiler is installed in a conned space and
all air is provided from the outdoors, the conned
space shall be provided with two permanent openings,
one commencing within 12 inches from the top and
one commencing 12 inches from the bottom of the
enclosure. The openings shall communicate directly, or
by ducts, with the outdoors or spaces (crawl or attic)
that freely communicate with the outdoors. One of the
following methods must be used to provide adequate
air for ventilation and combustion.

A. When directly communicating with the outdoors,

each opening shall have a minimum free area of 1
square inch per 4,000 BTU per hour of total input
rating of all equipment in the enclosure. (Figure

#4)

B. When communicating with the outdoors by means

of vertical ducts, each opening shall have a
minimum free area 1 square inch per 4,000 BTU
per hour of total input rating of all appliances in the
enclosed space. (Figure #5)

C. If horizontal ducts are used, each opening shall

have a minimum free area 1 square inch per 2,000
BTU per hour total input rating of all appliances in
the enclosed space. (Figure #6)

D. When ducts are used, they shall be of the same

cross sectional area as the free area of the area of
the openings to which they connect. The minimum
dimension of rectangular air ducts shall not be less
than 3 inches.

6.

In calculating free area using louvers, grills or screens
for the above, consideration shall be given to their
blocking effect. Screens used shall not be smaller than
1/4 inch mesh. If the free area through a design of
louver or grill is known, it should be used in calculating
the size opening required to provide the free area
specied. If the design and free area is not known, it
may be assumed that wood louvers will have 20-25%
free area and metal louvers and grills will have 60-75%
free area. Louvers and grills shall be xed in the open
position or interlocked with the boiler so that they are
opened automatically during boiler operation.

SUPPLY AND RETURN PIPING

!

WARNING

Burn or Scald Hazard. Discharge line shall be installed to safety valve outlet connection to avoid burns,
scalding, or water damage due to discharge of steam and/or hot water during operation.

Discharge line shall:

• Connect to safety valve outlet. Piped down to safe point of disposal. Check local codes for maximum
distance from oor or allowable safe point of discharge.

• Pipe size be of equal to or greater than of safety valve outlet over entire length of discharge line.

• Have no intervening shutoff valve between safety valve and discharge to atmosphere. Do not plug or
place any obstruction in discharge line.

• Terminate freely to atmosphere where any discharge will be clearly visible and at no risk of freezing.

• Allow complete drainage of valve and discharge line.

• Install safety valve with spindle in vertical position.

• Do not install shutoff valve between boiler and safety valve.

• Support safety valve discharge piping.

• Be short and straight as possible.

• Terminate with plain end, not threaded.

• Constructed of material suitable for exposure to temperatures of 375° F (191°C); or greater.

Refer to local codes and appropriate ASME Boiler and Pressure Vessel Code for additional installation
requirements.
