We recommend the immersion tube is positioned in the middle of
the top of the tank.
The immersion tube can be fitted to a boiler feedtank by the following

Using an existing flange.
The immersion tube is designed so that it can pass through an
apperture with dimensions according to BS 1600 Schedule 40.
The sandwich flange of the immersion tube is equal to the raised
face diameter of the flange for which it is suitable. Gaskets are
to be placed above and below the sandwich flange.
On new installations a specific connection should be incorporated,
as described in separate literature.
It is essential that a vacuum breaker is fitted to the condensate
return main near to the immersion tube. Consider the use of a
Spirax Sarco VB14 vacuum breaker.

Ideally fit a vacuum breaker here
How to order example:
1. Immersion tube IT150-950 in austentic stainless steel to suit
DN150, PN16 flanges complete with:
2. Silicone rubber gaskets to suit DN150, PN16.
Alternatively, fit a vacuum breaker here, as near to
the elbow as possible.
Use a blind flange of same DN as tank connection and drill
a hole to suit DN of condensate return main.
