A . Position the pipe work header against the wall. When using several pipe work
headers: couple the pipe work headers and supplied gaskets, M12 (DN65) or M16
(DN100) bolts, spring washers and nuts. Align the pipe work header(s) horizontally
using the adjustable feet.
B. Determine the position of the suspension brackets based on figure 5.1.c. The boi-
lers can be fitted on the wall using the supplied suspension brackets and mounting
material (minimum of 3 screws for each boiler). The wall has to be flat and strong
enough to carry the weight of all boilers including their water contents.
