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]
2. Determine Total Input of all appliances in space.
Round result to nearest 1,000 Btu per hour (Btuh).
3. Determine type of space. Divide Volume by Total
Input.
4
Page 5
a. If result is greater than or equal to 50 ft³ per
1,000 Btuh, space is considered an unconfi ned
space.
b. If result is less than 50 ft³ per 1,000 Btuh, space
is considered a confi ned space.
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;
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 fl oors, between wall-ceiling joints, between
wall panels, at plumbing and electrical
penetrations, and at other openings.
5. For boiler located in an unconfi ned space in a
building of other than unusually tight construction,
adequate combustion and ventilation air is normally
provided by fresh air infi ltration through cracks
around windows and doors.
6. For boiler located within unconfi ned space in
building of unusually tight construction or within
confi ned 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:
a. Direct communication with outdoors. Minimum
free area of 1 square inch per 4,000 Btu per hour
input of all equipment in space.
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.
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.
Alternate method for boiler located within confi ned
space. Use indoor air if two permanent openings
communicate directly with additional space(s) of
suffi cient volume such that combined volume of all
spaces meet criteria for unconfi ned 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.
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 fi xed in
open position or interlocked with equipment to open
automatically before burner operation. Screens must
not be smaller than ¼ inch mesh.
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.
I. Do not install boiler where gasoline or other
fl ammable vapors or liquids, or sources of hydrocarbons
(i.e. bleaches, cleaners, chemicals, sprays, paint
removers, fabric softeners, etc.) are used or stored.

Oxygen contamination sources are system leaks
requiring addition of makeup water, fi ttings, and
oxygen permeable materials in distribution system.
Eliminate oxygen contamination by repairing system
leaks, repairing fi ttings, and using nonpermeable
materials in distribution system.
B. Connect system supply and return piping to boiler.
See Figure 4A or 4B. 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 fl anges, 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.
D. Install Safety Relief Valve. See Figure 4A or 4B.
Safety Relief Valve must be installed with spindle in
vertical position. Installation of the relief valve must be
consistent with the ANSI/ASME Boiler and Pressure
Vessel Code, Section IV.

E. Install Drain Valve in ¾" NPT connection in tee
provided. See Figure 1.
F. Space heating and domestic water heating with
Alliance water heater. Install Alliance water heater as a
nitluseryamreliobepipylreporpoteruliaF
roreliobotegamaddnanoitareporeporpmi
separate heating zone. Refer to Alliance Installation,
Operating and Service Instructions for additional
information.
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 3. Also consult I=B=R
Installation and Piping Guides.
H. If boiler is connected to heating coils located in air
.eruliafreliobotdaelnacdna,stnenopmoc
handling units where they may be exposed to
refrigerated air, boiler piping must be equipped with
fl ow control valves to prevent gravity circulation of
boiler water during operation of cooling system.
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 4A or 4B. Bypass should be same size as the
supply and return lines with valves located in bypass
and supply outlet as illustrated in Figure 4A or 4B in
order to regulate water fl ow to maintain higher boiler
water temperatures.
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.
J. A hot water boiler installed above radiation level
must be provided with a low water cut-off device as
part of installation.
If a low water cut-off is required, it must be mounted in
ebtsumgnipipegrahcsidevlavfeilerytefaS
the system piping above the boiler.
The minimum safe water level of a hot water boiler is
just above the highest water containing cavity of the
boiler; that is, a hot water boiler must be full of water to
operate safely.
Refer to Section X for low water cut-off piping and
wiring instructions.
K. If it is required to perform a long term pressure test of
the hydronic system, the boiler should fi rst be isolated
to avoid a pressure loss due to the escape of air trapped
in the boiler.
6
Page 7
To perform a long term pressure test including the
boiler, ALL trapped air must fi rst be removed from the
boiler.
A loss of pressure during such a test, with no visible
water leakage, is an indication that the boiler contained
trapped air.
L. 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 fl ushed. A qualifi ed water treatment
chemical specialist should be consulted for
recommendations regarding appropriate chemical
compounds and concentrations which are compatible
with local environmental regulations.
M. After the boiler and system have been cleaned and
fl ushed, and before refi lling the entire system add
appropriate water treatment chemicals, if necessary, to
bring the pH between 7 and 11.

IV. Gas Piping
Figure 4B: Boiler Piping for Zone Valve Zoned Heating Systems
A. Size gas piping. Design system to provide adequate 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.
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).

3. Length of piping and number of fi ttings. Refer to
Table 2 for maximum capacity of Schedule 40 pipe.
Table 3 lists equivalent pipe length for standard
fi ttings.
4. Specifi c gravity of gas. Gas piping systems for gas
with a specifi c gravity of 0.70 or less can be sized
directly from Table 2, unless authority having
jurisdiction specifi es a gravity factor be applied. For
specifi c gravity greater than 0.70, apply gravity
factor from Table 4. If exact specifi c 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 liquefi ed petroleum gas.
8
Page 9
3. Install sediment trap, ground-joint union and manual
shut-off valve upstream of boiler gas control valve
and outside jacket. See Figure 6.
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.
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 nonfl ammable
solution. Do not use matches, candles, open fl ames,
or other ignition source.

General Guidelines.
1. Vent system installation must be in accordance with
National Fuel Gas Code, NFPA 54/ANSI Z221.3,
Part 7, Venting of Equipment; and/or CAN/CGA
B149 Installation Codes, Section 7, Venting Systems
and Air Supply for Appliances; or applicable
provisions of local building codes. Contact local
building or fi re offi cials about restrictions and
installation inspection in your area.
2. This appliance requires a Special Gas Vent. Use
Vent Connector and Vent Terminal in Vent
Accessory Carton provided with boiler (See Repair
Parts, Key No. 8). The product is designed to use
Burnham supplied AL 29-4C® Stainless Steel vent
system components. The following manufacturers
offer similar AL 29-4C® components and are
approved for use with this product: Heat-Fab Inc. Saf-T-Vent, Flex-L International Inc., - Star-34,
Protech Systems, Inc. - FasNSeal™, and Z-Flex U.
S., Inc. - Z-Vent. The use of these alternate
manufacturer's venting systems will require adapters
to connect to the Burnham supplied vent connector
and vent terminal. These adapters are not supplied
with this unit and should be obtained from the
supplier of the alternate manufacturer's venting
system. See Table 5 for complete list of Burnham
Vent System Components.
3. Vent length restrictions are based on equivalent feet
of vent pipe (total length of straight pipe in feet plus
5 equivalent feet for each 45° or 90° elbow). Do not
exceed the maximum certifi ed vent length of 25
equivalent feet. The minimum certifi ed vent length
is 7 equivalent feet. Do not include vent terminal or
vent connector in equivalent feet calculations.
4. Do not install venting system components on the
exterior of the building except as specifi cally
required by these instructions.
5. This 2PV boiler may only be sidewall vented; it may
not be vertically vented, as through a roof.
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:
1. Seal any unused openings in the common venting
system.
2. Visually inspect the venting system for proper size
and horizontal pitch and determine there is no
blockage or restriction, leakage, corrosion, and other
defi ciencies which could cause an unsafe condition.
3. 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 maxi mum
speed. Do not operate a summer exhaust fan. Close
fi replace dampers.
4. Place in operation the appliance being inspected.
Follow the Lighting (or Operating) Instructions.
Adjust thermo stat so appliance will operate
continuously.
5. Test for spillage at the drafthood relief opening after
5 minutes of main burner operation. Use the fl ame
of a match or candle, or smoke from a cigarette,
cigar or pipe.
6. After it has been determined that each appliance
remain ing connected to the common venting system
properly vents when tested as outlined above, return
doors, win dows, exhaust fans, fi replace dampers and
any other gas burning appliance to their previous
conditions of use.
7. Any improper operation of the common venting
system should be corrected so the installation
conforms with the National Fuel Gas Code, NFPA
54/ANSI Z223.1. When resizing any portion of the
common venting system, the common venting
system should be resized to approach the minimum
size as determined using the appropriate tables in
Part II in the National Fuel Gas Code, NFPA 54/
ANSI Z223.1.
C. Install Vent Connector.
1. Remove vent connector from vent accessory carton.
2. Remove gaskets, orifi ce plate and hardware from
blower outlet fl ange.
3. Assemble orifi ce plate gaskets, orifi ce plate, and

D. Install Vent Pipe, General.
1. Plan venting system to avoid possible contact with
plumbing or electrical wires. Start venting system at
vent connector and work toward the vent terminal.
2. Use non-combustible ¾ inch pipe strap to support
horizontal runs, maintain vent location and slope,
while preventing sags in pipe. Do not restrict
thermal expansion or movement of vent system.
Maximum support spacing is 5 feet. Do not
penetrate any part of the vent system with fasteners.
3. Provide and maintain vent pipe minimum clearance
to combustible materials. Vent pipe minimum
clearance to combustible material is fi ve (5) inches
when vent is installed in a fully enclosed (chase)
application or four (4) inches when vent is installed
with at least one side open, similar to a joist bay
application. Use thimble when penetrating
combustible wall.
a. 203PV and 204PV – Single wall thimble,
Burnham Part No. 8116116. Other wall thimble
manufac-turers are American Metal Products,
Hart & Cooley, and Metal Fab.
b. 205PV and 206PV – Double wall thimble,
Burnham Part No. 8116115 (accommodates 5
inch to 8-3/4 inch wall thickness). Another wall
thimble manufacturer is Hart & Cooley.
4. Once a vent pipe manufacturer and system is chosen
never mix and match vent systems.
5. If a non-standard length pipe is required:
Gasketed Vent System: The use of the adjustable length
pipe (P/N 8116319U) is recommended to complete a
non-standard pipe length. This pipe requires a
minimum installed length of 12¾ inch and can
adjust across a 7 inch gap up to a maximum of 19¾
inch long. (Note for the adjustable pipe the installed
length should be measured from the centerline of the
bead on the male end of the fi rst pipe to the end of
the female pipe excluding the locking band of the
second pipe with a single gasket.) Only in the event
the adjustable length pipe is not suffi cient a standard
length pipe may be cut using the procedure outlined
below for the Gasket-Less Vent System.

X. Low Water Cut Off (LWCO) on Hot Water Boilers
GNINRAW

.snoitcurtsnis'rerutcafunam)OCWL(ffOtuCretaWwoLehtwollof,sesacllanI
When
A low water cutoff is required to protect a hot water
boiler when any connected heat distributor (radiation) is
installed below the top of the hot water boiler (i.e.
baseboard on the same fl oor level as the boiler). In
addition, some jurisdictions require the use of a LWCO
with a hot water boiler.
Where
The universal location for a LWCO on both gas and oil
hot water boilers is above the boiler, in either the supply
or return piping. The minimum safe water level of a
water boiler is at the uppermost top of the boiler; that is,
it must be full of water to operate safely.
What Kind
Typically, in residential applications, a probe type
LWCO is used instead of a fl oat type, due to their
relative costs and the simplicity of piping for a probe
LWCO.
How to Pipe
A “tee” is commonly used to connect the probe LWCO
to the supply or return piping, as shown below.
draining the heating system. Many probe LWCO
manufacturers recommend an annual inspection of the
probe.
How to Wire
LWCO’s are available in either 120 VAC or 24 VAC
confi gurations. The 120 VAC confi guration can be
universally applied to both gas and oil boilers by wiring
it in the line voltage service to the boiler (after the
service switch, if so equipped).
The presence of water in a properly installed LWCO
will cause the normally open contact of the LWCO to
close, thus providing continuity of the 120 VAC service
to the boiler.
It is recommended to supply power to the probe LWCO
with the same line voltage boiler service as shown
below.
LWCO Location
Select the appropriate size tee using the LWCO
manufacturer’s instructions. Often, the branch
connection must have a minimum diameter to
prevent bridging between the probe and the tee. Also,
the run of the tee must have a minimum diameter to
prevent the end of the probe from touching or being
located too close to the inside wall of the run of the tee.
Ideally, manual shutoff valves should be located above
the LWCO and the boiler to allow for servicing. This
will allow probe removal for inspection without
Wiring of Typical LWCO
A 24 VAC LWCO is used primarily for gas fi red boilers
where a 24 volt control circuit exists within the boiler.
However, a 24 VAC LWCO can only be used if the
boiler manufacturer has provided piping and wiring
connections and instructions to allow for this
application.
How to Test
Shut off fuel supply. Lower water level until water
level is BELOW the LWCO. Generate a boiler demand
by turning up thermostat. Boiler should not attempt to
operate. Increase the water level by fi lling the system.
The boiler should attempt to operate once the water
level is above the LWCO.
