Installation & Servicing
A. ELECTRICAL INSTALLATION
1.
Checks to ensure electrical
safety should be carried out by
a competent person.
2.
ALWAYS carry out preliminary
electrical system checks, i.e.
earth continuity, polarity,
resistance to earth and short
circuit using a suitable test
meter.
C. WATER CIRCULATING
SYSTEM
1.
The whole of the system
should be thoroughly flushed
out with cold water WITHOUT
the pump in position. Ensure
that all valves are open.
2.
With the pump fitted the
system should be filled and
air locks cleared. Check for
water soundness.
B. GAS INSTALLATION
1.
The whole of the gas installation,
including the meter, MUST be inspected
and tested for soundness, and purged in
accordance with the recommendations of
BS. 6891. In I.E. refer to I.S.813:2002.
2.
Purging air from the gas installation may
be expedited by loosening the union on
the gas service cock on the boiler and
purging until gas is detected.
3.
Retighten the union and check for gas
soundness.
WARNING.
Whilst effecting the required gas soundness test and purging air from the gas
installation, open all windows and doors, extinguish naked lights and
