5.4.1

Installing B-kit

The safety valve and pressure/temperature gauge are
installed into the supply manifold as described below:
B Use the 1-1/4" BSP x NPT conversion nipple and
install the unmarked end into the supply (VK)
connection of the boiler. This side also has longer
thread length and the thread is straight (BSP).
B The conversion nipple is marked on the 1-1/4" NPT
side with pink color and a NPT stamping in the pipe.
B Seal 90° 1-1/4 NPT elbow on double nipple.
B Mount conversion nipple on the elbow and align as
desired (Fig. 16).
B Seal 90° elbow, safety valve and pressure/temperature
gauge.
The safety valve can only be installed after the
hydrostatic test (Chapter 5.5, page 24) has
been completed.
Use the supplied ¾" 90° elbow to ensure
that the safety valve is installed horizontally.
We recommend installing a dirt filter
(optional) in the boiler return connection to
reduce build-up of debris on the water side.
