and exhaust may be vented vertically through the roof or out a side
wall.
The intake and exhaust venting methods are detailed in the
General venting Section. Do not attempt to install the boiler using
any other means. Be sure to locate the boiler such that the air
intake and exhaust vent piping can be routed through the building
and properly terminated. The air intake and exhaust vent piping
lengths, routing and termination method must all comply with the
methods and limits given within the Venting section.
6 .4 Prevent combustion air contamination
Install intake air piping for this boiler as described in the Venting
section. Do not terminate exhaust in locations that can allow for
contamination of the intake air.
9
WARNING: You must pipe outside air to the boiler air intake
for sealed combustion operation. Ensure that the intake air will
not contain any of the contaminants below. Contaminated air
will damage the boiler, resulting in possible severe personal
injury, death or substantial property damage. For example, do
not pipe the intake air vent near a swimming pool. Also avoid
areas subject to exhaust fumes from laundry facilities. These
areas may contain contaminants.
6 .5 When removing an existing boiler from an
existing common vent system
Do not install the boiler into a common vent with any other appliance.
This will cause flue gas spillage or appliance malfunction, resulting
in possible severe personal injury, death or substantial property
damage.
9
WARNING: Failure to follow all instructions can result in flue
gas spillage and carbon monoxide emissions, causing severe
personal injury or death.
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 appliances remaining connected to it.
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.
Seal any unused openings in the common venting system.
A
Visually inspect the venting system for proper size and
B
horizontal pitch and to determine there is no blockage or
restriction, leakage, corrosion and other deficiencies which
could cause an unsafe condition.
Insofar as is practical, close all building doors and windows and
C
all doors between the space in which the appliances remaining
connected to the common venting system are located and
other spaces of the building, so long as it is practical to do so.
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.
Place in operation the appliance being inspected. Follow the
D
lighting instructions. Adjust thermostat so the appliance will
operate continuously.
Test for spillage at the draft hood relief opening after 5 minutes
E
of main burner operation. Use the flame of a match or candle,
or smoke from a cigarette, cigar or pipe.
F
After it has been determined that each boiler remaining
connected to the common venting system properly vents when
tested as outlined above, return doors, windows, exhaust fans,
fireplace dampers and any other gas burning boiler to their
previous condition of use.
Any improper operation of the common venting system should
G
be corrected so the installation conforms with the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 — latest edition. Correct by
resizing to approach the minimum size as determined using
the appropriate tables in ANSI Z223.1/NFPA 54 of that code.
Canadian installations must comply with CAN/CSA B149.1
Installation Code.
9
WARNING: Verify proper operation after servicing.
6 .6 Prepare the boiler
9
CAUTION: Cold weather handling — If boiler has been stored
in a very cold location (below 0°F (-18°C)) before installation,
handle with care until the plastic components come to room
temperature.
7 INSTALLATION
Wall mounting information
7 .1
The boiler comes with a template, which allows you to easily mark
the location of the screws for the mounting bracket and the location
of the flue gas pipe on the wall.
The gas connection must be made on site, a 3/4" gas cock is
supplied with the boiler.
9
WARNING: This boiler is heavy and awkward to lift. It is
recommended and safer to install the boiler with two people.
Use caution as to not drop the boiler which could cause
personal injury. Verify that the boiler is securely mounted
before leaving the boiler unsupervised.
The wall must be vertically plumb and capable of carrying the
weight of the boiler and its related components.
9
CAUTION: If the boiler is not vertically plumb, improper and
unsatisfactory operation may occur. This will cause excessive
condensation build-up resulting in unnecessary maintenance
and nuisance fault codes.
NOTICE: The mounting bracket is shown for installation of the
combi and heating only boiler.
Placing the wall-mounted boiler
7 .1 .1
The boilers are wall mounted. Use only the combi and heating only
boiler wall mounting instructions included in the box.
9
WARNING:
The
the weight of the boiler and its related components.
The shipping weights of the boiler are approximately:
BWCAAG000120 - combi = 89 lb (40.5 kg)
BWHAAG000120 - only heating = 87 lb (39.5 kg)
BWCAAG000150 - combi = 97 lb (44 kg)
BWHAAG000150 - only heating = 94 lb (43 kg)
Failure to comply with above could result in severe personal injury,
death or substantial property damage.
