reduces required floor area.
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: General Installation of Boilers (p16)
Ref.: - spacing plates for further information. See
Figure 2.1 (p3) re: - coupling of Warmwell and
Purewell boilers. The boiler can also be installed in
a 'stand alone configuration' if required.
2.2 General Information and Technical Data relating
to Natural Gas is shown in Figure 2.2 (p4).
Technical data relating to propane firing can be
found in Appendix 'A' (p41).

certainly result in an unsatisfactory installation.
3.2 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.
