conform to the Standard for Controls and Safety
Devices for Automatically Fired Boilers, ANSI/ASME
CSD-1.
WARNING
Certified as Category III appliance. Install
vent system in accordance with Section
V: Venting. Do not vent using masonry
chimney, Type B gas vent, or other
Category I venting system.
G. Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during boiler operation
and service (circulator replacement, condensate trap,
control replacement, etc.).
H. Provide combustion and ventilation air in accordance
with applicable provisions of local building codes, or
National Fuel Gas Code, NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Ventilation, or
Sections 7.2, 7.3 or 7.4 of CAN/CGA B149 Installation
Codes.
WARNING
Adequate combustion and ventilation air
must be provided to assure proper
combustion.
The following guideline is based on the National Fuel
Gas Code, NFPA 54/ANSI Z223.1.
1. Determine volume of space (boiler room). Rooms
communicating directly with space (through
openings not furnished with doors) are considered
part of space.
Volume [ft³] = Length [ft] x Width [ft] x Height [ft]
Figure 2: Minimum Clearances to Combustible
Construction for Closet Installation

2. Determine Total Input of all appliances in space.
Round result to nearest 1,000 Btu per hour (Btuh).
a. Direct communication with outdoors. Minimum
free area of 1 square inch per 4,000 Btu per hour
input of all equipment in space.
3. Determine type of space. Divide Volume by Total
Input.
b. Vertical ducts. Minimum free area of 1 square
inch per 4,000 Btu per hour input of all equipment
in space. Duct cross-sectional area shall be same
as opening free area.
a. If result is greater than or equal to 50 ft³ per 1,000
Btuh, space is considered an unconfined space.
b. If result is less than 50 ft³ per 1,000 Btuh, space is
considered a confined space.
c. Horizontal ducts. Minimum free area of 1 square
inch per 2,000 Btu per hour input of all equipment
in space. Duct cross-sectional area shall be same
as opening free area.
4. Determine building type. A building of unusually
tight construction has the following characteristics:
a. Walls and ceiling exposed to outside atmosphere
have a continuous water vapor retarder with a
rating of 1 perm or less with openings gasketed
and sealed, and;
Alternate method for boiler located within confined
space. Use indoor air if two permanent openings
communicate directly with additional space(s) of
sufficient volume such that combined volume of all
spaces meet criteria for unconfined space. Size each
opening for minimum free area of 1 square inch per
1,000 Btu per hour input of all equipment in spaces,
but not less than 100 square inches.
b. Weather-stripping has been added on openable
windows and doors, and;
c. Caulking or sealants applied in joints around
window and door frames, between sole plates
and floors, between wall-ceiling joints, between
wall panels, at plumbing and electrical
penetrations, and at other openings.
7. Ventilation Duct Louvers and Grilles. Equip outside
openings with louvers to prevent entrance of rain
and snow, and screens to prevent entrance of
insects and rodents. Louvers and grilles must be
fixed in open position or interlocked with equipment
to open automatically before burner operation.
Screens must not be smaller than ¼ inch mesh.
5. For boiler located in an unconfined space in a
building of other than unusually tight construction,
adequate combustion and ventilation air is normally
provided by fresh air infiltration through cracks
around windows and doors.
Consider the blocking effect of louvers, grilles and
screens when calculating the opening size to provide
the required free area. If free area of louver or grille is
not known, assume wood louvers have 20-25 percent
free area and metal louvers and grilles have 60-75
percent free area.
6. For boiler located within unconfined space in
building of unusually tight construction or within
confined space, provide outdoor air through two
permanent openings which communicate directly or
by duct with the outdoors or spaces (crawl or attic)
freely communicating with the outdoors. Locate one
opening within 12 inches of top of space. Locate
remaining opening within 12 inches of bottom of
space. Minimum dimension of air opening is 3
inches. Size each opening per following:
I. Do not install boiler where gasoline or other flammable
vapors or liquids, or sources of hydrocarbons (i.e.
bleaches, cleaners, chemicals, sprays, paint removers,
fabric softeners, etc.) are used or stored.
II. Unpack Boiler
CAUTION
D. Remove all boiler hold-down fasteners.
Do not drop boiler. Do not bump boiler
jacket against floor.
E. Tilt the boiler to one side and slide a wooden slat under
the two raised feet.
A. Move boiler to approximate installed position.
F. Tilt the boiler to the other side and slide another
wooden slat under the two raised feet.
B. Remove all crate fasteners.
G. Slide the boiler forward or backward off the skid using
C. Lift outside container and remove with all other inside
the two wooden slats as runners.
protective spacers and bracing. Save two of the
wooden slats from the container sleeve for use in
Paragraphs E and F.
H. Move boiler to its permanent location.

III. Water Piping and Trim
F. Space heating and domestic water heating with Alliance
CAUTION
water heater. Install Alliance water heater as a separate
heating zone. Refer to Alliance Installation, Operating and
Service Instructions for additional information.
Failure to properly pipe boiler may result in
improper operation and damage to boiler or
building.
G. If boiler is used in connection with refrigeration systems ,
boiler must be installed with chilled medium piped in
parallel with the heating boiler using appropriate valves to
prevent chilled medium from entering boiler, see Figure 4.
Also consult I=B=R Installation and Piping Guides.
A. Design and install boiler and system piping to prevent
oxygen contamination of boiler water.
H. If boiler is connected to heating coils located in air
handling units where they may be exposed to refrigerated
air, boiler piping must be equipped with flow control
valves to prevent gravity circulation of boiler water during
operation of cooling system.
CAUTION
Oxygen contamination of boiler water will
cause corrosion of iron and steel boiler
components, and can lead to boiler failure.
Burnham's standard warranty does not
cover problems caused by oxygen
contamination of boiler water.
I. Use a boiler bypass if the boiler is to be operated in a
system which has a large volume or excessive radiation
where low boiler water temperatures may be encountered
(i.e. converted gravity circulation system, etc.).
Install pipe tee between circulator and boiler return along
with second tee in supply piping as shown in Figure 3.
Bypass should be same size as the supply and return lines
with valves located in bypass and supply outlet as
illustrated in Figure 3 in order to regulate water flow to
maintain higher boiler water temperatures.
Oxygen contamination sources are system leaks
requiring addition of makeup water, fittings, and oxygen
permeable materials in distribution system. Eliminate
oxygen contamination by repairing system leaks,
repairing fittings, and using nonpermeable materials in
distribution system.
After the boiler is operational (reference Section VII.
System Start-Up) set by-pass and boiler supply valves to
half throttle position to start. Operate boiler until system
water temperature reaches normal operating range.
Adjust valves to provide 180° to 200°F supply water
temperature. Opening the boiler supply valve will raise
system temperature, while opening the by-pass valve will
lower system supply temperature.
B. Connect system supply and return piping to boiler. See
Figure 3. Also consult I=B=R Installation and Piping
Guides. Maintain minimum ½ inch clearance from hot
water piping to combustible materials.
C. Install Circulator with flanges, gaskets and bolts
provided. Five foot circulator harness allows circulator
to be mounted on supply or return. Connect harness to
circulator and secure any excess conduit.
J. A hot water boiler installed above radiation level must be
provided with a low water cut-off device as part of
installation.
D. Install Safety Relief Valve. See Figure 3. Safety Relief
Valve must be installed with spindle in vertical position.
Installation of the relief valve must be consistant with
the ANSI/ASME Boiler and Pressure Vessel Code,
Section IV.
K. Oil, grease, and other foreign materials which
accumulate in new hot water boilers and a new or
reworked system should be boiled out, and then
thoroughly flushed. A qualified water treatment chemical
specialist should be consulted for recommendations
regarding appropriate chemical compounds and
concentrations which are compatible with local
environmental regulations.
WARNING
Safety relief valve discharge piping must be
piped near floor to eliminate potential of
severe burns. Do not pipe in any area
where freezing could occur. Do not install
any shut-off valves.
L. After the boiler and system have been cleaned and
flushed, and before refilling the entire system add
appropriate water treatment chemicals, if necessary, to
bring the pH between 7 and 11.
E. Install Drain Valve in ¾" NPT connection in tee
provided. See Figure 1.

gas supply to boiler. Consider these factors:
1. Allowable pressure drop from point of delivery to
boiler. Maximum allowable system pressure is ½
psig. Actual point of delivery pressure may be less;
contact gas supplier for additional information.
Minimum gas valve inlet pressure is listed on
rating label.
4. All above ground gas piping upstream from manual
shut-off valve must be electrically continuous and
bonded to a grounding electrode. Do not use gas
piping as grounding electrode. Refer to National
Electrical Code, ANSI/NFPA 70 and/or CSA C22
Electrical Code.
2. Maximum gas demand. Table 1 lists boiler input
rate. Also consider existing and expected future gas
utilization equipment (i.e. water heater, cooking
equipment).
C. Pressure test. The boiler and its gas connection must
be leak tested before placing boiler in operation.
1. Protect boiler gas control valve. For all testing over
½ psig, boiler and its individual shut-off valve must
be disconnected from gas supply piping. For testing
at ½ psig or less, isolate boiler from gas supply
piping by closing boiler's individual manual shut-off
valve.

2. Locate leaks using approved combustible gas
detector, soap and water, or similar nonflammable
solution. Do not use matches, candles, open flames,
or other ignition source.
3. Length of piping and number of fittings. Refer to
Table 2 for maximum capacity of Schedule 40 pipe.
Table 3 lists equivalent pipe length for standard
fittings.
4. Specific gravity of gas. Gas piping systems for gas
with a specific gravity of 0.70 or less can be sized
directly from Table 2, unless authority having
jurisdiction specifies a gravity factor be applied. For
specific gravity greater than 0.70, apply gravity
factor from Table 4. If exact specific gravity is not
shown choose next higher value.
For materials or conditions other than those listed
above, refer to National Fuel Gas Code, NFPA 54/
ANSI Z223.1, or size system using standard
engineering methods acceptable to authority having
jurisdiction.
B. Connect boiler gas valve to gas supply system.
1. Use methods and materials in accordance with local
plumbing codes and requirements of gas supplier.
In absence of such requirements, follow National
Fuel Gas Code, NFPA 54/ANSI Z223.1 and/or
CAN/CGA B149 Installation Codes.
2. Use thread (joint) compounds (pipe dope) resistant
to action of liquefied petroleum gas.

4. Do not install venting system components on the
exterior of the building except as specifically required
by these instructions.
B. Removal of Existing Boiler. For installations not
involving the replacement of an existing boiler, proceed
to Step C.
When an existing boiler is removed from a common
venting system, the common venting system is likely to
be too large for proper venting of the remaining
appliances. At the time of removal of an existing boiler,
the following steps shall be followed with each
appliance remaining connected to the common venting
system placed in operation, while the other appliances
remaining connected to the common venting system are
not in operation:
(a) Seal any unused openings in the common venting
system.
(b) Visually inspect the venting system for proper size
and horizontal pitch and determine there is no
blockage or restriction, leakage, corrosion, and other
deficiencies which could cause an unsafe condition.
(c) Insofar as is practical, close all building doors and
windows and all doors between the space in which
the appliances remaining connected to the common
venting system are located and other spaces of the
building. Turn on clothes dryers and any appliance
not connected to the common venting system. Turn
on any exhaust fans, such as range-hoods and
bathroom exhausts, so they will operate at maximum
speed. Do not operate a summer exhaust fan. Close
fireplace dampers.
