INTRODUCTION
!
WARNING
Improper installation, adjustment, alteration, service
or maintenance could result in death or serious
injury.
• Installation must conform to requirements of the
authority having jurisdiction. Such applicable
requirements take precedence over the general
instructions of this manual.
• Install boiler in accordance with requirements of
authority having jurisdiction, or in the absence of such
requirements, CSA B139: Installation Code for Oil
Burning Equipment.
• 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 level solid base as near the
chimney as possible, and centrally located with respect
to heat distribution system as practical.
• Allow 24 inches in the front and top for servicing and
cleaning, or removing tankless water heating coil.
• When installed in utility room, door should be wide
enough to allow largest boiler part to enter, or to permit
replacement of another appliance such as water heater.
!
WARNING
Fire hazard. Do not install boiler on combustible
ooring or carpeting. Failure to follow these
instructions could result in death or serious injury.
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.

NOTICE
Clearance for access should exceed re protection
clearance.
REMOVE CRATE and plastic protective wrapper, inspect for
damage.
Move boiler to permanent position by sliding or walking.

1.
Ventilation of boiler room must be adequate enough to
provide sufcient air to properly support combustion.
2.
When 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. Provide combustion
air and ventilation air in accordance with the section
“Air for Combustion and Ventilation,” of NFPA 31:
Standard for the Installation of Oil-Burning Equipment.
3.
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 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.
6
VENTILATION & COMBUSTION AIR
4.
When air for combustion and room ventilation is from
inside buildings, conned 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 one thousand (1,000)
Btu per hour of the total input rating of all appliances
in the enclosed space, but must not be less than one
hundred (100) square inches. These openings must
freely communicate with the interior areas having
adequate inltration from the outside. See Figure #1.
5.
When the boiler is installed in a conned space and
all air is provided from the outdoors, the conned
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. See
Figure #2.
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. See Figure #3.
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. See Figure #4.
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
¼ 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
specied. If the design and free area is not known,
it may be assumed that wood louvers will have 2025% 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.
Refer to the Combustion Air Requirements chart on
previous page for combustion air minimum opening
requirements.

CONNECTING SUPPLY AND RETURN PIPING
1.
Connect supply and return piping as suggested in
Figure #5, below. When boiler is used in connection
with refrigerated systems:
A. Chilled medium MUST BE IN PARALLEL with boiler.
B. Use appropriate valves to prevent chilled medium
from entering heating boiler.
2.
During heating cycle open valves A and B, close valves
C and D.
3.
During heating cooling cycle open valves C and D, close
valves A and B.
A. Maintain minimum clearance of one inch to hot
water pipes.
In air handling units where they may be exposed to
refrigerated air circulation, boiler piping system MUST be
supplied with ow control valves or other automatic means
to prevent gravity circulation of boiler water during cooling
cycle.
4.
Hot water boilers installed above radiation level must
be provided with low water device either as part of
boiler or at time of boiler installation.
5.
When boiler is connected to heating system utilizing
multiple zoned circulators, each circulator must be
supplied with ow control valve to prevent gravity
circulation.
* Reduced pressure back ow preventer must be used
under provisions required by the Environmental
Protection Agency, (EPA).
6.
Bypass piping is an option which gives ability to
adjust supply boiler water temperature to t system
or condition of installation. Although, this method of
piping is not typically required for baseboard heating
systems.
