Initial Inspection - Vaillant TURBOmax Pro 28 Instructions For Installation And Servicing

Initial Inspection

To ensure the continued safe and
efficient operation of the boiler it is
recommended that it is checked and
serviced as necessary at regular
intervals. The frequency of servicing
will depend upon the particular
installation conditions and usage, but
in general once per year should be
adequate. It is the law that all ser-
vicing work is carried out by a com-
petent person (Corgi registered).
Important: Before starting any
maintenance work:
Isolate the mains electricity supply
by disconnecting the plug at the
socket outlet (if there is only an
isolating switch remove the fuse
from the switch).
Turn OFF the gas supply at the gas
service valve fitted to the boiler.
Always test for gas soundness and
always carry out functional checks
after any service work and after
exchanging any gas carrying
component.
Always check earth continuity,
polarity and resistance to earth
with a multimeter after any service
work and after exchanging any
electrical component.
Note: The boiler is fitted with a
combustion analysis test point. A
suitable combustion analyser can be
connected to this point to establish
the combustion performance of the
boiler.
SERVICING
Before commencing any servicing or
maintenance work, carry out an initial
inspection of the system as follows:
Inspect the flue, pipework and
electrical connections for
indications of damage or
deterioration.
Inspect the air supply and
ventilation arrangements of the
installation.
Check the heating and water
system, in particular the condition
of radiator valves, evidence of
leakage from the heating system
and dripping hot water taps.
Functional check of boiler operation
Carry out a functional check of the
boiler operation as prevoiusly
detailed.
Remove the appliance casing as
detailed on page 20 and operate
the boiler by fully opening a hot
water tap. Inspect the burner
operation through the viewing
window. Check that the flames are
evenly covering the surface of the
burner. Inspect for signs of
excessive flame lift or sooting.
