INSTALLATION
The installation must conform to the requi-
rements of the Authority having jurisdiction
or, in the absence of such requirement, to
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.
This boiler is equiped with a pressure tran-
sducer that cuts-off power to the ignition
sequence if the pressure of the heating cir-
cuit water falls below 0.7bar (10.2psi). For
boilers that are installed above the radia-
tion level, inquire with Authority having juri-
sdiction for additional requirements for low
water cut-off devices at the time of installa-
tion.
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 cleaning 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 damage the front insu-
lation.
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 reas-
sembly 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 following
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
2
(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.
2.2
BOILER SUPPORT BRACKET
For the mounting of the support bracket of
the boiler, which is supplied, observe the fol-
lowing instructions (fig. 4):
– Fix the bracket to the wall with appro-
priate dowels.
– Check with a spirit level that it is perfec-
tly in horizontal plane.
– To fix the boiler with the lives evidenced
in figure.
2.2. 1
System connection unions
The follow is available to facilitate water and
gas connection of the boiler with the heating
system: for assembly of the unions to see
fig. 1.
2.3
CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, flakes or deposits, before instal-
lation it is extremely important to clean the
system using suitable products such as,
descaler or slug removing solution.
