Concord CXA/H - Installation and Servicing

GENERAL
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 3 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
o
C (150
o
F).
MULTIPLE BOILER INSTALLATIONS
The minimum installation clearances must conform to the
dimensions given below:
CXA 40/H, 50/H, 60/H, 70/H & 80/H
Clearance between boilers = 50mm
Clearance at both ends of the multiple installation = 50mm*
2 CLEARANCES & DIMENSIONS
Table 3
CXA 90/H, 100/H, 110/H & 120/H
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.
