outside. See Figure 2.
below, to maintain adequate combustion air.
1.
Ventilation of boiler room must be adequate enough to
provide sufcient air to properly support combustion
and venting.
2.
When the 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 conned space. If there is any
doubt, install air supply provisions for combustion and
ventilation in accordance with requirements of authority
having juridiction, or in absence of such requirements,
Air for Combustion and Ventilation of the NFPA 31.
3.
When the 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.

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 3.
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 4.
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 5.
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
specied. 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.

CONNECTING SUPPLY AND RETURN PIPING
3.
During heating cooling cycle open valves C and D, close
valves A and B.
A. Maintain a minimum clearance of one (1") inch to
hot water pipes. In air handling units where they
may be exposed to refrigerated air circulation, the
boiler piping system MUST be supplied with ow
control valves or other automatic means to prevent
gravity circulation of the boiler water during the
cooling cycle.
4.
Hot water boilers installed above radiation level must
be provided with a low water device either as part of
the boiler or at the time of boiler installation.
5.
When a boiler is connected to a heating system that
utilizes multiple zoned circulators, each circulator must
be supplied with a ow control valve to prevent gravity
circulation.
* Reduced pressure back ow preventer must be
present under provisions required by the Environmental
Protection Agency, (EPA).
6.
Bypass piping is an option which gives the ability to
adjust the supply boiler water temperature to t the
system or condition of the installation. Although, this
method of piping is not typically required for baseboard
heating systems.
A. This method is used to protect systems using
radiant panels and the material they are encased
in from high temperature supply water from the
boiler. See Figure 7, page 7.
B. This method is used to protect boilers from
condensate forming due to low temperature return
water. Generally noticed in large converted gravity
systems or other large water volume systems. See
Figure 8.
C. This method is used to protect boilers from
condensate forming as well as protecting the
heating system from high water temperature. See
Figure 9, page 9.
7.
Note: When using bypass piping, adjust valves A and
B until desired system temperature is obtained.
8.
Bypass loop piping must be same size piping for supply
and return.

VENTING SYSTEM INSPECTION & INSTALLATION
WARNING
!
Figure 15 Chimney Installation
Boiler and venting installations shall be performed
by a qualied expert and in accordance with the
appropriate manual. Installing or venting boiler
or other appliances with improper methods or
materials may result in serious injury or death due
to re or to asphyxiation from poisonous gases such
as carbon monoxide with is odorless and invisible.
!
WARNING
Do not connect boiler to any portion of mechanical
draft system operating under positive pressure.
• Inspect chimney. Verify construction supplies with
requirements of authority having jurisdiction, or in
absence of such requirements, NFPA 211: Standard
for Chimneys, Fireplaces, Vents and Solid Fuel-Burning
Appliances.
• Install boiler into chimney which has masonry or metallic
chimney liner.
• Unlined chimney will have leaks that will cause poor
chimney performance (no draft), and could result in
positive pressure in the combustion chamber.
• Horizontal portions of venting system should not exceed
10 ft. in length. Horizontal lengths over 10 ft. will have
negative effect on chimney performance.
• Chimney should extend at least 2 ft. above any portion
of building within 10 ft. See Figure 15. It should produce
a -.06 to -.08 inch W.C. draft, as measured with draft
gauge between boiler and barometric draft control while
maintaining .02 inch W.C. negative draft in combustion
chamber. . See "Chimney or Vent Sizes" chart for
recommended minimum and maximum chimney or vent
sizes.
• Inadequate draft will cause improper combustion,
resulting in dirty ue ways and high fuel bills.
• Connect ue pipe same size as boiler outlet to chimney,
sloping upward continuously toward the chimney
approximately ¼" per foot. Bolt or screw joints together
to avoid sag.
• If oil red water heater is vented into same ue as boiler,
provide separate hole into chimney whenever possible.
When this isn’t possible, use “Y” connection in ue
pipe, using separate draft regulator for each unit. When
chimney will not provide adequate draft to handle input
from water heater and boiler simultaneously, wire units
so only one will operate at a time, favoring water heater.

• Drill ¼" diameter hole in ue pipe between boiler and
barometric damper (if used) to take draft, CO2, smoke
and temperature readings. Plug hole when done.
• Adjust air shutter on oil burner to obtain “trace” of
smoke. Measure CO2 at this point.
• Increase air adjustment to lower CO2 approximately one
percent.
• Verify minimum negative .02 w.c., (water column),
“overre” draft and zero smoke.
• If -.02 w.c. “overre” draft can not be maintained,
changes and/or modications may be required in venting
or chimney.
• See table below as guideline for initial start-up. Make
nal adjustments using combustion instruments.
Check safety control circuit after burner adjustments

MAINTENANCE PROCEDURES
Regular Maintenance
• Inspect venting system at start of each heating season.
Check vent pipe from boiler to chimney for signs
of deterioration by rust or sagging joints. Repair if
necessary.
• Remove vent pipe at base of chimney or ue. Use mirror,
check for obstruction.
• Verify compliance to the latest revision of the NFPA 211.
• Operate lever of safety relief valve on boiler periodically
to verify that it is functioning properly. Open pressure
relief valve before water pressure exceeds 30 psi reading
on gauge. If pressure is exceeded and pressure relief
valve leaks water when boiler is operating at normal
pressures, replace immediately. Corrosion can build at
valve seat and prevent functioning as safety device.
Annual Inspection - Before Start of Heating Season
Periodically or at start of heating season inspect boiler, vent
and vent pipe for accumulation of soot or scale deposits.
When soot is present on section walls and ueways,
improper combustion results, causing additional sooting
and scaling until ueways are completely closed.
A. To remove soot and scale from ueways, remove
top jacket panel, top clean-out plate and burner. See
instructions on Removing Oil Boiler. Use wire brush,
brush soot and scale into combustion chamber where
it can be removed through burner opening.
Do not overtighten bolts.
Periodic inspection and tightening of tankless heater/
cover plate bolts reduce the risk of leaks. CAUTION: Do not
overtighten bolts.
