5.2 Fitting the water connections

5.2.1 Fitting the B-kit

The safety relief valve and the pressure/temperature

gauge are mounted on the supply manifold (included in B-

Kit) on the VK boiler supply connection as follows:

V Fit and seal unmarked end of double nipple into con-

nection VK on the boiler.

V Converter is paint-marked pink and stamped with the

designation NPT on the end with the 1¼" NPT thread.

Caution: Risk of system damage from leak-

ing connections.

V Support the pipes to the boiler to prevent

them from being under stress.

Do not fit the safety valve until the leak test

(Æ Chapter 5.3, page 21) has been com-

pleted.

The relief valve must be installed in a vertical

position.

We recommend installing a dirt filter (option-

al) in the boiler return connection to reduce

build-up of debris on the water side.
