Installing the boiler
This chapter describes how to install and place the
boiler in the boiler room.
CAUTION: Risk of system damage from
freezing.
B Install the heating system in a frost-free
room.
4.1
Wall clearances
Position the boiler with the recommended wall
clearances. Reducing the minimum clearances makes
the boiler more difficult to access during installation,
maintenance and cleaning.
The boiler base or foundation must be perfectly flat and
level.
The burner door is factory-fitted with the hinges on the
right. The burner door can be converted to open to the
left.

silencer or other flue components, etc.
CAUTION: Risk of fire from flammable
materials or liquids.

clearance between combustible
materials and the chimney connection as
specified by NFPA 31 (distance of 18 "
(460 mm)).
