INSTALLATION
The installation must conform to the requi-
ENG
rements of the Authority having jurisdiction
or, in the absence of such requirement, to
FR
t he National Fuel Gas Code, ANSI
Z223. 1 /NFPA 54 or CAN/CSA B149. 1
natural gas and propane Installation Code.
Where required by the Authority having
jurisdiction, the installation must conform
to the Standard for Controls and Safety
Devices for Automatically Fired Boilers,
ANSI/ASME CSD-1.
All boilers must be installed with a proper
pressure relief valve.
Pressure relief valves must be installed to
conform to ANSI/ASME Boiler and Pressu-
re Vessel Code, Section IV, or CSA B51, as
applicable.
If the boiler is installed above the radiation
level, or as required by the Authority having
jurisdiction, the installer must provide a low
water cut-off device at a time of installation.
The boiler must be installed in a fixed loca-
tion and only by a qualified installer, service
agency or the gas supplier and is familiar
with the requirements that are contained
in this manual.
The boiler must not be installed on carpe-
ting.
The boiler when used in connection with a
refrigeration system, must be installed so
the chilled medium is piped in parallel with
the boiler with appropriate valves to pre-
vent the chilled medium from entering the
boiler.
The boiler piping system of a hot water boi-
ler connected to heating coils located in air
handling units where they may be exposed
to refrigerated air circulation must be
equipped with flow control valves or other
automatic means to prevent gravity circula-
tion of the boiler water during the cooling
cycle.
Service instructions and recommended fre-
quency guidelines periodic examination of
venting systems every six months.
Venting sy s t ems, t he vent-air int ake
system, screens in the vent terminal
should be checked and cleaned every six
months.
Low water cutoff should be checked and
cleaned every six months.
Remove small cover retaining screw and
remove the cover.
When the pump is running and water is
flowing around the boiler , the actuator lifts
off the micro switch.
Check that the operation of the actuator ;
Ensure that it is free and that it lifts and
returns.
If necessary lubricate the pivot point of
the actuator.
Flue gas passageways should be checked
and cleaned every six months.
Condensate collection and disposal system
should be checked and re-sealed every six
months.
The burner should be checked and cleaned
every six months. Inspect the burner and
if necessary clean using a soft brush and a
vacuum cleaner, taking care not to dama-
ge the front insulation.

Check the ignition /ionisation electrode,
check the ignition spark gap (4 mm +/-
0.5 mm) (0. 1 6 in. +/- 0.02 in.). Check the
ionisation electrode, check the distance
from the burner (18.7 mm +/- 1 mm)
(0.74 in. +/- 0.04 in).
Before reassembly inspect all seals and
replace as required.
Furthermore, the installation must be in
accordance with current standards and
regulations.
2. 1
VENTILATION OF BOILER ROOM
When using air from the boiler room, an
adequate air supply shall by provided for
combustion of this boiler.
An insufficient supply can result in poor
combustion and possible sooting of the
burner, combustion chamber or flue pas-
sageway.
The boilers installed using inside air supply
must provide provisions for Combustion Air
and Ventilation Air in accordance with sec-
tion 5.3, Air for Combustion and Ventilation,
of the National Fuel Gas Code, ANSI Z
223, 1 /NFPA 54, or section 7,2, 7.3, or 7.4,
of CAN/CSA B 149, Installation Codes, or
local codes having jurisdiction.
Where an exhaust fan or any other air con-
suming appliance is installed in the same
space as the boiler, sufficient air openings
must be available to provide fresh air when
all appliance are operating simultaneously.
It is essential that in rooms where the boi-
ler are installed at least as much air can
arrive as required by normal combustion of
the gas consumed by the varius appliances.
Consequently, it is necessary to make ope-
nings in the walls for the air inlet into the
rooms. These openings must meet the fol-
lowing requirements:
1. Have a total free section of a least
2225 mm
2
every kW (1 in
1000 Btu/hr) of heat input, with a
minimum of 100 cm

(15.5 in
2. Where required by jursdiction or
when required for additional opening
must be provided at the highest ele-

vation practical.
With a hermetically sealed combustion
chamber and air supply circuit from out-
doors, may be installed in any room in the
home.
Keep boiler area clear and free from com-
bustible materials, gasoline and other flam-
mable vapors and liquids.
2. 1 . 1
Indirect D.H.W.
"BFT" model may be paired with a separate
indirect D.H.W. tank unit.
The tank units may be installed near the
boiler (beneath or beside it) or in another
room.
An optional hydraulic connection kit (code
8091110) is available to facilitate installa-
tion underneath the boiler.

FIXING THE WALL
MOUNTING BRACKET
– Mark the position of the two wall mount-
ing bracket fixing holes and the flue/air
duct hole on the appropriate wall(s).
– Drill the top two fixing holes using a 10
mm (0.4 in) masonry drill and fit the
plastic plugs provided.
– Accurately measure the wall thickness,
and note this dimension for later use.
– Secure the wall mounting bracket in
position using the screws provided.
Ensure that it is the correct way up, as
indicated in fig. 4.

gas connection of the boiler with the heating
system: for assembly of the unions to see fig. 1.
