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:
CXD 40, 50, 60 & 70
Clearance between boilers = 50mm
Clearance at both ends of the multiple installation = 50mm
*
Graph 2 - Hydraulic Resistance
Graph 1 - Heat Load / Water Volume
CX 90 & 100
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.
