Installing the boiler on a boiler base or foundation

When setting up the boiler, we recommend you observe the specified
wall clearances for improved installation and maintenance ( Fig. 5).
It is advisable to place the boiler on a 2 – 4 inch (50 – 80 mm) tall base
( Fig. 6, [1]). The base should be completely flat and level. The front
edge of the boiler should be flush with the edge of the base.
A concrete foundation can be constructed on-site. When building the
foundation, a 3 15/16 x 1 31/32 x 5/16 inches (100 x 50 x 8 mm) steel
angle or 3 15/16 x 13/64 inches (100 x 5 mm) steel flat should be
incorporated ( Fig. 6 and Tab. 9).

Depending on the type of delivery, we distinguish between delivery
unassembled and as a ready assembled block. When delivered as a
ready-assembled block, the boiler is assembled and checked for leaks
prior to despatch. If, because of physical limitations, a boiler block
cannot be assembled as a complete unit, delivery unassembled would
enable assembly on site.
For details of assembling the remainder of the boiler if the heat
exchanger is delivered pre-assembled, see  Chapter 7.3, page 16.
