Concord CXC -
Installation
GENERAL
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.
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
200mm.
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
o
C (150
o
F).
MULTIPLE BOILER INSTALLATIONS
The minimum installation clearances must conform to the
dimensions given below:
CXC 48 & 70
Clearance between boilers = 50mm
Clearance at both ends of the multiple installation = 50mm*
CXC 94 & 116
Clearance between boilers = 100mm
Clearance at both ends of the multiple installation = 100mm*
