4.41 Initial Boiler Ignition
Preliminary Checks
W A R N I N G !
To ensure the continued safe operation of the boiler it is highly recommended that it is checked
at regular intervals and serviced when necessary, and that only original spare parts are used.
Regular attention will prolong the life of the boiler.
Before igniting the boiler check that:
•
The boiler installation has been carried out in accordance with the specific standards as
instructed in this manual.
•
The combustion air inlet and the discharge of combustion exhaust occur in the correct
manner in accordance to the specific standards in force.
•
The
gas supply system is correctly configured for the boiler’s output.
•
The
boiler’s electrical supply is 120 V - 60 Hz.
•
The system has been filled with water (pressure registered on the gauge 0.8/1 bar with
pump not running).
•
All on/off valves are in the appropriate position (open or closed as required)
•
The mains gas supply corresponds to the one which the boiler has been calibrated for.
Otherwise convert the boiler to use the available gas (refer to section: “GAS
CONVERSION”). This operation must be carried out by a qualified technician in
compliance with the regulations in force.
•
The gas supply valve is open.
•
There are no gas leaks.
•
There are no water leaks.
•
The external mains electrical supply switch is on.
•
The
system’s safety valve is not blocked and is connected to the waste water system.
•
The condensate drain line (section 4.16) has been filled with water and that it is connected
to the waste water system.
•
All the necessary ventilation conditions and minimum clearance distances are in place for
subsequent servicing in case the boiler is sited in a cupboard compartment.
W A R N I N G !
Before firing up the appliance, be sure to fill up the condensate drain line (see section 4.16)
through the filling hole and check the correct drainage of the condensate.
Using the boiler with the condensate drain pipe empty could cause a dangerous condition due
to poisonous emissions from the flue exhaust gasses.
