5.0 BOILER ASSEMBLY
General
Boilers are despatched to site as fully assembled units. The flue pipe, condensate drain connection and pipework
manifold set (where applicable) are the items that will need assembling on site.
During assembly it is important to take care to prevent damage to the boiler casing. DO NOT STAND ON THE
CASING PANELS.
Boiler positioning must allow the minimum clearances detailed in Section 3.0 to facilitate access for flue and
pipework connections as well as maintenance. Boilers can be positioned side by side, no clearance is necessary.
5.1 Flue Pipe
So as to avoid damage, the flue connecting pipe is supplied separately.
Fit the elbow to the base of the boiler and secure using the gasket and 4 - M8 x 16 Hex Head Screws. Moisten the
lip seal and engage the flue pipe into the elbow. Secure the flue pipe to the boiler casing using the bracket
supplied.
5.2 Water Connections:
Connecting pipework must be self-supporting to avoid stress on the boiler connections. Local unions are
recommended in the pipework to facilitate future servicing requirements.
The following connections are provided on each boiler module;
