Clearances

Position the boiler with the recommended wall clearances. Reducing the
minimum clearances makes the boiler more difficult to access.
The base or foundation on which the boiler is to stand must be perfectly
flat and level. The boiler may be installed on a combustible base, but not
on carpet.
Wall clearance
Dimension inches (mm)
A 33 (840)
B 6 (155)
C 2 (50)
Table 6 Wall clearances
Where applicable, allow extra wall clearances for
additional components such as DHW storage tank, pipe
connections, flue silencer or other flue components, etc.
A space of at least 33 inches (840 mm) is required in front of the boiler
with the door open to allow sufficient accessibility for operation and
maintenance. When the door is closed, a minimum clearance of 2 inches
(50 mm) is required at the front and sides, a wall clearance of 6 inches
(155 mm) is also required for the flue pipe and 30 inches (762 mm)
clearance to the ceiling.

Leveling the boiler

The boiler must be leveled horizontally and vertically to prevent air
pockets forming inside.
▶ Level the boiler vertically and horizontally, inserting metal shims
underneath as required.
NOTICE: Risk of system damage due to contamination!
▶ Protect boiler connections from damage and dirt if the
boiler is not to be installed immediately.

leaves the factory. However, if you discover any damage
or missing parts, please inform the supplier
immediately. Before disposing of packing material,
make sure that no parts are still in it.
