WaRning
if you do not follow these instructions exactly,
a re or explosion may result causing property
damage or personal injury.
DangER
Do not install boiler where gasoline or other
ammable vapors or liquids, or sources of
hydrocarbons (i.e. bleaches, cleaners, chemicals,
sprays, paint removers, fabric softeners, etc.) are
used or stored.
nOTiCE
Due to the low water content of the boiler, mis-
sizing of the boiler with regard to the heating
system load will result in excessive boiler cycling
and accelerated component failure. Burnham
DOES nOT warrant failures caused by mis-sized
boiler applications. DO nOT oversize the boiler to
the system. Modular boiler installations greatly
reduce the likelihood of boiler oversizing.
A. Installation must conform to the requirements of the
authority having jurisdiction. In the absence of such
requirements, installation must conform to the National
Fuel Gas Code, NFPA 54/ANSI Z223.1, and/or CAN/
CSA B149.1 Installation Codes.
B. Appliance is design certied for installation on
combustible ooring. Do not install boiler on
carpeting.
C. Provide clearance between boiler jacket and
combustible material in accordance with local re
ordinance. Refer to Figure 2 for minimum listed
clearances from combustible material. Recommended
service clearance is 24 inches from left side, front, top
and rear of the boiler. Recommended front clearance
may be reduced to the combustible material clearance
providing:
1. Access to boiler front is provided through a door or
removable front access panel.
ii. Pre-installation
2. Access is provided to the condensate trap located
underneath the heat exchanger.
D. Install on level oor. For basement installation provide
a solid base such as concrete, if oor is not level or if
water may be encountered on oor around boiler. Floor
must be able to support weight of boiler, water and all
additional system components.
E. Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during boiler operation
and service (circulator replacement, condensate trap,
control replacement, etc.).
F. Provide combustion and ventilation air in accordance
with applicable provisions of local building codes,
or: USA - National Fuel Gas Code, NFPA 54/ANSI
Z223.1, Air for Combustion and Ventilation;
Canada - Natural Gas and Propane Installation Code,
CAN/CSA-B149.1, Venting Systems and Air Supply for
Appliances.
WaRning
Adequate combustion and ventilation air must
be provided to assure proper combustion.
G. The boiler should be located so as to minimize the
length of the vent system. The PVC combustion
air piping, or the optional concentric vent piping,
containing integral combustion air inlet piping, must
terminate where outdoor air is available for combustion
and away from areas that may contaminate combustion
air. In particular, avoid areas near chemical products
containing chlorines, chloro/uorocarbons, paint
removers, cleaning solvents and detergents. Avoid
areas containing saw dust, loose insulation bers, dry
wall dust etc.
CaUTiOn
avoid operating this boiler in an environment
where saw dust, loose insulation bers, dry wall
dust, etc. are present. if boiler is operated under
these conditions, the burner interior and ports
must be cleaned and inspected daily to insure
proper operation.

iV. Venting
WaRning
Failure to vent this boiler in accordance with these instructions could cause products of combustion to
enter the building resulting in severe property damage, personal injury or death.
Do not interchange vent systems or materials unless otherwise specied.
The use of thermal insulation covering pipe and ttings is prohibited.
Do not use a barometric damper, draft hood or vent damper with this boiler.
The use of CPVC is required when venting in chase ways and through interior wall penetrations.
Do not locate vent termination where exposed to prevailing winds. Moisture and ice may form on
surface around vent termination. To prevent deterioration, surface must be in good repair (sealed,
painted, etc.).
Do not locate vent termination where chlorines, chloro/uorocarbons (CFC’s), petroleum distillates,
detergents, volatile vapors or other chemicals are present. Severe boiler corrosion and failure will
result.
The use of cellular core PVC (
aSTM F891) is prohibited.
Do not locate vent termination under a deck.
Do not reduce size of vent/combustion air pipe diameter.
When installing vent pipe through chimney, no other appliance can be vented into the chimney.
Do not allow low spots in the vent where condensate may pool.
A. Vent Guidelines Due to Removal of an Existing
Boiler
For installations not involving the replacement of an
existing boiler, proceed to Step B.
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
deciencies 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 maximum
speed. Do not operate a summer exhaust fan. Close
replace dampers.
4. Place in operation the appliance being inspected.
Follow the Lighting (or Operating) Instructions.
Adjust therm
ostat so appliance will operate
continuously.
5. Test for spillage at the draft hood relief opening
after ve (5) minutes of main burner operation. Use
the ame of a match or candle, or smoke from a
cigarette, cigar or pipe.
6. After it has been determined that each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, 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.
B. General Guidelines
1. Vent system installation must be in accordance
with National Fuel Gas Code, NFPA 54/ANSI
Z221.3 or applicable provisions of local building
codes. Contact local building or re ofcials about
restrictions and installation inspection in your area.
11
2. The Alpine™ is designed to be installed as a Direct
Vent boiler. The air for combustion is supplied
directly to the burner enclosure from outdoors and
ue gases are vented directly outdoors (through wall
or roof).
3. The following combustion air/vent system options
are approved for use with the Alpine™ boilers:
i. Two-Pipe CPVC/PVC Gas Vent/Combustion
Air System (factory standard) - separate
CPVC/PVC pipe serves to expel products of
combustion and separate PVC pipe delivers fresh
outdoor combustion air. Refer to Paragraph C
through F for specic details.
ii. Combination Concentric Gas Vent/
Combustion Air Inlet (optional) - the assembly
consists of inner re resistant polypropylene
vent pipe and outer steel pipe casing. The inner
pipe serves as conduit to expel products of
combustion, while outdoor fresh combustion air
is drawn through the space between the inner and
outer pipes. Refer to Paragraphs G through P for
specic details.
4. Refer to Table 3 and the appropriate drawings to
determine the proper conguration of either factory
standard or optional venting/combustion air system
details.
C. The following information is applicable for Two-
Pipe CPVC/PVC Gas Vent/Combustion Air System
(factory standard).
WaRning
all CPVC vent components (supplied with boiler)
must be used for near-boiler vent piping before
transitioning to Schedule 40 PVC pipe (aSTM
2665) components for remainder of vent system.
CPVC vent components must be used prior to
exit of any closet or conned space.
See
Table 6 for complete list of Burnham Vent
System Components. Use single wall thimble
[Burnham Part No. 102180-01 (3”), 102181-01 (4”)]
when penetrating a combustible wall for vent only.
1.
Horizontal vent pipe must maintain a minimum ¼
inch per foot slope down towards boiler.
2. Use noncombustible ¾ inch pipe strap to support
horizontal runs and maintain vent location and slope
while preventing sags in pipe. Maximum support
spacing is four (4) feet. Avoid low spots where
condensate may pool. Do not penetrate any part of
the vent system with fasteners.
WaRning
all condensate that forms in the vent must be
able to drain back to the boiler.
3.
Vent length restrictions are based on equivalent
length of vent/combustion air pipe (total length
of straight pipe plus equivalent length of ttings).
Maximum vent/combustion air lengths are listed in
Table 7. Do not exceed maximum vent/combustion
air lengths. Table 6 lists equivalent lengths for
ttings. Do not include vent/combustion air
terminals in equivalent feet calculations. See
“Combustion Air/Vent, Equivalent Length Work
Sheet”.
4. Provide minimum service clearance between boiler
back and concentric vent exiting through outside
wall, for concentric vent installation/replacement
and/or ue temperature sensor service/replacement.
5. Do not install venting system components on
the exterior of the building except as specically
required by these instructions. The vent termination
location is restricted as follows (refer to Figures 6
and 9):

When Additional Concentric Vent Piping is
needed
1. If additional concentric vent piping is needed:
a. Concentric Vent Cut-To-Length Extension pipes,
identied in Tables 8 and 10 CAN BE CUT
to required length when used as an extension.
These pipes have plain male end and beaded
female end. Always cut the pipe from plain
male end. See Figure 20 ‘Cut-To-Length
Extension (Cuttable)”.
b. The remaining Concentric Vent Fixed Extensions
shown in Table 8 CANNOT BE CUT. These
pipes have beaded male and beaded female ends.
See Figure 21 ‘Fixed Extension (Non-Cuttable)’.
2. To cut the Concentric Vent Straight pipe to required
length refer to Figure 22 “Cutting Straight Pipe” and
follow the procedure below:
a. Determine the required length of the outer pipe.
When doing this allow an additional 1” of length
for insertion into the female end of the adjoining
pipe. Mark the cut line on the outer pipe.

Figure 20: Cut-To-Length Extension (Cuttable)
b.
Remove the plastic inner pipe by pulling it out
from the female end.
c.
Cut the OUTER PIPE ONLY at the point
marked in Step (a) using aviation shears, a
hacksaw, or an abrasive wheel cutter. Be careful
to cut the pipe square. Deburr the cut end with a
le or emery cloth.
d. Make an insertion mark 1” from the male end of
the outer pipe.
e. Cut the plastic inner pipe so that it will protrude
3/8” beyond the male end of the outer pipe when
reinstalled in the outer pipe. Use a ne tooth
hacksaw or a PvC saw to cut the plastic pipe and
be careful to cut the pipe square. Deburr the cut
edge of the plastic pipe with a le, razor blade or
ne sandpaper.
f. Reinstall the inner pipe.
3. To join Concentric Vent Pipe refer to Figure 23
“Joining Cuttable Pipe” and Figure 24 “Joining
Non-Cuttable Pipe” and follow the procedure below:
a. Start assembly of the vent system at the boiler.
Lubricate the brown gasket in the boiler vent
collar with a few drops of water.
25
Figure 22: Cutting Straight Pipe
Figure 23: Joining Cuttable Pipe
Figure 24: Joining non-Cuttable Pipe
b. Push the male end of the rst tting into the
boiler collar until it bottoms out. The male end
of cuttable sections should go 1” into the collar
until the insertion mark (made in Step 2d above)
is covered. On other ttings, the bead on the
male pipe will be bottom out on the collar (see
Figure 24).
c.
The male end of cuttable ttings must be held to
the collar with three (3) #10 x 1/2” sheet metal
screws. Drill a 1/8 hole through both outer pipes
to start this screw. Use a drill stop or other
means to ensure that the drill bit does not
penetrate more than 3/8” into the outer pipe.
Do not use a sheet metal screw longer than
1/2” (see Figure 23).
d. Use locking bands (provided with all ttings) to
secure non-cuttable pipe, as well as ttings, to
the boiler collar (see Figure 24).
e. Use the same method to join all remaining vent
components except for the terminal.
Vertical (Roof Terminal Installation
1. Vertical (Roof) Terminal Installation. Refer to
Figures 26, 27 and 28.
In addition to the vertical terminal, either a Flat
Roof Flashing or Sloped Roof Flashing is required
for this installation. Refer to Table 8 ‘Concentric
Vent Components’ for details.
26
Figure 26: Cutting Vertical Terminal
a. Determine the centerline of the terminal location
on the roof. For at roof, cut either 5-1/2”
diameter hole (80/125 mm concentric vent size)
or 6-1/2” diameter hole (100/150 mm concentric
vent size) for the terminal. For sloped roof, cut a
hole in the roof large enough for the terminal to
pass through the roof while remaining plumb.
CaUTiOn
if the boiler is located directly under the hole,
cover it while cutting the hole to prevent debris
from falling onto boiler.
b. Install the roof ashing using standard practice
on the roong system of the structure.
c.
If not already done, assemble the venting system
inside the building. The last section of pipe needs
to be on the same center line as the terminal
and within 19-1/4” of the top edge of the roof
ashing.
d.
Measure distance “H” from the top edge of the
storm collar to the end of the last tting as shown
in Figure 25.
e. Add 1” to distance “H”. Carefully mark this
length on the pipe as shown in Figure 26.
f. Cut the outer pipe only at the point marked in
Step (e) using aviation shears, a hacksaw, or an
abrasive wheel cutter. Be careful to cut the pipe
square. De-burr the cut end with a le or emery
cloth.
g.
Place a mark on the plastic inner pipe 3/8”
beyond the end of the outer pipe (Figure 26).
Use a ne tooth hacksaw to cut the plastic pipe
and be careful to cut the pipe square. De-burr the
cut edge of the plastic pipe with a le or emery
cloth.
h. Make a mark on the terminal section 1” from the
cut end of the outer pipe as shown in Figure 26.
i. Slip the terminal section through the roof from
the outside. Push into the last section of vent
pipe until the mark made in Step (h) is not
longer visible. Secure the terminal to the last
piece of pipe with three #10 x 1/2” sheet metal
screws. Drill a 1/8” hole through both outer
pipes to start these screws. Use a drill stop or
other means to ensure that the drill bit does
not penetrate more than 3/8” into the outer
pipe. Do not use a sheet metal screw longer
than 1/2”.
j. Secure the terminal section to the inside of
the roof structure using the mounting bracket
provided with the terminal (Figure 27).

Chimney Chase Installation.
A vertical concentric vent system, either 80/125 mm
or 100/150 mm can be installed in an UNUSED
masonry chimney. Refer to Figure 28.
a. The Chimney chase Support Elbow with
attached Mounting Bracket is used at the base
of the chimney. Refer to Table 8 ‘Concentric
Vent Components’ for details. Slip the elbow
over the M10 x 35 screw in the support bracket.
Determine the desired vertical location of the
support elbow in the chimney and mark the
location of the pin, positioned on the back of
the support bracket, onto the chimney rear wall.
Drill a 7/16” diameter x 3-1/2” deep hole in the
marked location, then, insert the back bracket pin
into the hole. The front of the elbow mounting
bracket should be supported either by bottom of
the opening into chimney or installer supplied
spacer.
b.
Construct a weather-tight at roof to cover
the top of the old chimney. Install the vertical
terminal through this roof using the at roof
ashing.

V. Condensate Disposal
A. Condensate Trap and Drain Line.
1. All condensate, which forms in the boiler or vent
system, collects in the sump under heat exchanger
and leaves the boiler through factory installed
condensate trap.
2. The trap allows condensate to drain from sump
while retaining ue gases in the boiler. The trap
has factory installed overow switch, which shuts
down the boiler in the event the drain line becomes
obstructed, preventing proper condensate removal.
Refer to Section XIII “Service and Maintenance”
for condensate trap and condensate overow switch
removal and replacement procedure, if required.
3. Note the following when disposing of the
condensate:
a. Condensate is slightly acidic, typical pH around
3.5 - 4.5. Do not use metallic pipe or ttings in
the condensate drain line. Do not route the drain
line through areas that could be damaged by
leaking condensate.
b.
Do not route or terminate the condensate drain
line in arrears subject to freezing temperatures.
c. If the point of condensate disposal is above the
trap, a condensate pump is required to move
the condensate to the drain. Select a condensate
pump approved for use with condensing
furnaces. If overow from the pump would
result in property damage, select a pump with an
overow switch. Wire this switch in series with
installer provided external high limit, to shut off
the boiler, and, if desired, in series with installer-
supplied alarm, to trigger an alarm in the event
of overow.
d. Do not attempt to substitute another trap for one
provided with the boiler.
e. In order for boiler to work properly, the boiler
must be leveled during installation.
4. The condensate trap stub is located at boiler left
side, below inlet and outlet water pipe connections.
Refer to Figures 1A and 1B.
5. Condensate trap must be lled up with water,
prior to boiler start-up and before connecting any
condensate line to the boiler, to insure combustion
products cannot escape from operating boiler. To ll
the trap, inject water in the amount of 1 cup (8 uid
ounces) through condensate trap stub opening. Do
not overll the trap.
6. If any additional condensate drain line is needed,
construct the extension from PVC or CPVC
Schedule 40 pipe. The factory supplied ¾” x 5-5/8”
long PVC coupling, located in the Part Carton, must
be used to connect drain line to the condensate trap
stub. Do not over tighten coupling compression nuts
when connecting drain line and condensate trap
stub.
WaRning
Failure to install the condensate trap and
condensate drain in accordance with the above
instructions could cause ue gas to enter the
building, resulting in personal injury or death.
CaUTiOn
Boiler condensate is corrosive. Route
condensate drain line in a manner such
that any condensate leakage will not cause
property damage.
Some jurisdictions may require that
condensate be neutralized prior to disposal.
nOTiCE
Use materials approved by the authority having
jurisdiction.
B. Condensate Neutralizer Installation
1. Some jurisdictions may require that the condensate
be neutralized before being disposed of. Follow
local codes pertaining to condensate disposal.
2. A Condensate Neutralizer Kit (P/N 101867-01)
is available as optional equipment. Follow local
codes and instructions enclosed with the kit for
Condensate Neutralizer installation.
3. Limestone chips will get coated by neutral salts
(product of chemical reaction between limestone
and acidic condensate) and lose neutralizing
effectiveness over time. Therefore, periodic
condensate neutralizer maintenance and limestone
chip replacement must be performed. A pH test or
acid test kits are available from HVAC/plumbing
distributors and should be used to measure
condensate acidity before/after neutralizer thus
indicating a need for service and chip replacement.
