Cold water pressure test:
The assembled boiler is to be subjected to a cold
water pressure test of 1.5 times the operating pressure.
The maximum test pressure of the boiler is 5.2 bar.
In addition, at the time of testing for water pressure,
no pressure control fittings or safety fittings may be
assembled which cannot be separated from the water
area of the boiler.
Only fill, slowly from the bottom via the filling and
draining cock.
Ventilate during the filling procedure from time to
time, until the water emerges.
If a nipple connection is leaking then drain off the
water via the filling and draining cock. Separate by
driving flat wedges around the perimeter of the join
between sections. New nipples MUST be used for re-
assembly.
Assemble and repeat test.
The order of assembly from (1) to (7) must be
observed.
Important points:
•
When fitting the long injection tube (1) (only
fitted to boilers with 7 sections or more) care
should be taken to ensure that the holes for the
direction of water, are facing upwards.
•
The boiler flow (3) must be assembled with the
connection facing upwards eccentrically.
•
The boiler return (2) must be assembled with the
connection facing downwards eccentrically.
•
It is possible to hinge the door to swing from
either side of the front section. Car should be
taken to ensure the burner plug is mounted
accordingly.
