Leak test

Carry out a leak test on the boiler only when loose
sections are delivered. Pre-assembled sections are
leak tested in the factory.
Therefore the following steps only apply to boilers
delivered in loose sections.
For the further installation of pre-assembled boiler
segments, see chapter "2.6.4 Insert the hot gas baffle
plates", page 20.
2.5.1 Leak test preparation
Close the lower boiler hub at the front and rear
( Fig. 21, [3]). To do this, set the corresponding
gasket ( Fig. 21, [1]) onto the respective boiler hub
and seal the corresponding drain plug into the
appropriate port.
Fit the plug with internal ¾" thread for the drain cock
( Fig. 21, [2]) to the rear of the boiler.
Fit the drain cock (not supplied as standard).
Close the flow and return connections (install the
flange with vent screw on the flow connections).
ATTENTION!
When you carry out the leak test, no control
or safety equipment must be connected to
the water system. These could be
damaged by high pressure.
