Installation of the boiler
The boiler must be installed respecting the minimum indicated
distances to allow the necessary maintenance work to be car-
ried out. The position “A” depends on the burner model used.

The recommended height for the boiler room is at least 2,200
mm, leave the minimum space free on the sides and in front of
the boiler as shown in the drawing.
Provide a base for the RTT 59-69-79 boilers with a minimum
height of 200 mm off the floor for the installation of the burner
of the boiler.
Characteristics of the base:
− it should be made of BS 25 fibre concrete,
− it should respect the indicated dimensions,
− it should not be covered with a slippery material like ce-
ramic, etc.
− any acoustic insulation should be made before the base.
In the RTT 29-79 boilers, the door of the burner can open on both
sides. For this reason, equal free distances are specified on both
sides (min. 700 mm). This characteristic is advantageous for op-
erations to be carried out on the boiler. If the space available
in the boiler room is not sufficient for the distances indicated,
you can choose the opening side and leave more space free on
that part. On the other part, half the indicated free distance is
sufficient.
Provide enough space for the tools to be used in the boiler room.
