TECHNICAL DATA
2.1
Overall dimensions are shown in Figure 2.1 (p3).
Both single and multiple boiler arrangements are
shown.
The Warmwell boiler can be installed as a single
unit or in modular form where a 'multi' casing
reduces required floor area. Each boiler has an
independent door for access to the controls and
other working components.
It is recommended that a maximum of 6 boilers can
be positioned on 533mm (21") centres if required.
Larger numbers should be split into two or more
banks with 150mm (6") between each bank.
NOTE!
To install modular units on 533mm (21") centres, the
casing support rail or spacing plates should be fitted
between each boiler before bolting together. See
Section
10.1:

(p16)
Ref.: - spacing plates for further information. See
Figure 2.1 (p3) re: - coupling of Warmwell and

Feed Water Quality
If the boiler feed water has a high degree of
hardness, it is recommended that the water be
treated to prevent precipitation of scale or sludge in
the boiler water passageways. Details of additives
can be obtained from any reliable manufacturer of
water treatment products or the local water
authority.
