Table 4
POSITION OF BOILER
Minimum clearances required
from walls or other fixed objects
to allow for the free access of
combustion air are shown in
Table 4 above.
However, for maintenance
purposes we suggest a
minimum rear clearance of
50mm.
Any combustible material
adjacent to the boiler and its flue
system must be so placed or
shielded as to ensure that its
temperature does not exceed 65
0
C (150
0
F).
MULTIPLE BOILER INSTALLATIONS
The minimum installation clearances must
conform to the dimensions given below:
CXS 40, 50, 60, 70 & 80
Clearance between boilers = 50mm
Clearance at both ends of the multiple installation = 50mm
*
Graph 2 - Hydraulic Resistance
Graph 1 - Heat Load / Water Volume
CXS 90,100, 110 & 120
Clearance between boilers = 100mm
Clearance at both ends of the multiple installation = 100mm
*
Rear clearance:
sufficient clearance should be given at the
rear of the boiler for connection of gas and water pipework.
*
Additional clearance is required for access at either end of
the installation.
