11 COMMISSIONING
11.1
Preliminary checks
When commissioning the boiler, the first ignition is carried out
by competent person from an authorized service agency.
Massachusetts:
Boiler installation must conform to Commonwealth of
Massachusetts code 248 CMR which includes but is not
limited to:
Installation by licensed plumber or gas fitter.
In the state of Massachusetts:
− This product must be installed by a licensed plumber or gas
fitter.
− When flexible connectors are used, the maximum length
shall not exceed 36” (914 mm).
− When lever type gas shutoffs are used they shall be T−handle
type.
− The use of copper tubing for gas piping is not approved by the
state of Massachusetts.
Gas boilers manufactured on or after May 1, 2017 are not permitted
to be used in Canada for heating of buildings or structures under
construction.
Before starting up the boiler, check:
− that the data of the supply networks (electricity, water, gas)
correspond to the label data
− that the exhaust extraction pipes and the air inlet pipes are
working correctly
− ensure the vent system has been installed properly and in
accordance with the instructions and codes
− verify there is enough access to the boiler to perform future
maintenance and future repairs
− check the gas piping system to the boiler for leaks. Close the
boiler’s individual manual shutoff valve during any pressure
testing of the gas supply piping system. Test at pressures
equal to or less than 1/2 psi (3.5 kPa) and check for leaks using
gas detector
− non corrosive detection fluid, or other leak detection method
acceptable to local codes. Do not use open flames or other
ignition sources to check for leaks. Correct all leaks, are re-test
for leaks to verify correction
− that the fuel flow rate corresponds to values required by the
boiler (check using gas meter)
− that the fuel supply system is sized to provide the correct flow
rate to the boiler, and that it has all the safety and control
devices required by current regulations
− that the hydronic system has been filled, vented, and the
pressure set to 15 p.s.i. (1 bar)
− that the circulator rotates freely because, especially after long
periods of inactivity, deposits and/or debris can prevent free
rotation (see section “11.7.1 Boiler configuration”.
11.2
Instructing the user
Hand over all documentation supplied with this appliance – in-
cluding these instructions – and explain the importance of keeping
them in a safe place.
Explain to the user how to isolate the appliance from the gas, water
and electrical supplies, and the locations of all drain points. Show
the user how to operate the appliance and any associated controls
correctly.
Show the user the location of any isolating valves and the location
of all manual vent points.
Explain to the user how to turn off the appliance for both long and
short periods and advise on the necessary precautions to prevent
freeze damage.
Explain to the user not to try to repair the boiler personally. Call a
qualified technician.
Explain to the user that for continued safe and efficient operation, the
appliance must be serviced annually by a qualified service person.
11.3
Initial flushing of the system
The whole of the heating system must be flushed before con-
necting this boiler to the heating system. Open all radiator or
heating valves and the boiler supply & return service valve. Drain
the boiler and system from the lowest points. Open the drain
valve completely to remove any installation debris from the boiler.
Refill the boiler and heating system (see section “7.16 Initial filling
of the system and air purge” for more details).
Once the system is brought to the central heating setpoint, it is
recommended that a second flush and fill be commenced to
remove any other contaminants from the system.

DANGER
: When flushing the system there is a risk of spraying,
scalding water proper precautions should be made to
prevent severe injury or death.
9
Do not drain or flush the system until it has reached room
temperature.
NOTICE
: Chemicals used to clean the system and/or inhibit
corrosion must be pH neutral, i.e. they should ensure that the
level of the pH in the system water remains neutral.Premature
failure of certain components can occur if the level of pH in the
system water is out of normal levels.
11.4
Flushing of the heating system
The system shall be flushed. Cleaners or chemicals used, must
be suitable for stainless steel heat exchangers and shall be from
a reputable manufacturer and shall be administered in strict
accordance with the manufacturers’ instructions.
NOTICE
: Chemicals used to clean the system and/or inhibit
corrosion must be pH neutral, i.e. they should ensure that the
level of the pH in the system water remains neutral. Premature
failure of certain components can occur if the level of pH in the
system water is out of normal levels.
11.5
Eventual releasing of the circulator shaft
The pump used in the boiler is a wet rotor pump; for this reason
the pump should be bled by:
− Turn the closing cap with a large flat-bladed screw driver
until is release from the seal, and some fluid begins dripping.
− Re-tighten the closing cap to reseal.
− Perform this operation with extreme
CAUTION
to avoid
damaging the components.
NOTICE
: Before loosening or removing the closing cap, protect
any electrical devices underneath any water outlet.
NOTICE
: The boilers are live-fired tested at the factory. In some
instances water can dry around the pump impeller causing it to
stick upon initial commissioning. This can be resolved by
removing the closing cap and spinning the impeller with a #2
Phillips screwdriver.
11.6
Access to the technical parameters
Using the boiler control panel it is possible to access the
technical parameters, using the TECHNICAL menu, a series of
parameters that can be programmed to allow you to personalize
the operation of the boiler:
− select MENU on the initial page of the user interface and press
the
