Alpine Installation, Operating, and Service Instructions

103448-10 - 6/18 11
Factory assembled floor standing models are
identified with suffix F in a boiler part number
code (example _ ALP210BF-4G02). Factory
assembled wall hung models are identified
with suffix W in a boiler part number code
(example - ALP210BW-4G02).
5. Boiler Floor Standing Installation:
a. For basement installation provide a solid
base such as concrete, where floor is not
level or water may be encountered on the
floor around boiler.
Floor must be able to support weight of
boiler, water and all additional system
components.
b. Boiler must be level to prevent condensate
from backing up inside the boiler.
c. Provide adequate space for condensate
piping or a condensate pump if required.
Boiler Clearances to Combustible (and Non-
Combustible) Material:
Models ALP080B through ALP210B and
ALP285B:
These boilers are listed for closet installation with
the following minimum clearances – Top = 1 in.
(25 mm), Front = 1 in. (25 mm), Left Side = 10 in.
(250 mm), Right Side = 2 in. (50 mm), Rear = *6
in. (150 mm)
* Note:
When boiler is vented vertically, the minimum
clearance from the rear of the jacket is
increased to 18 in. (460 mm) with a short
radius 90° elbow in order to provide adequate
space at boiler rear for installation of vent and
air intake piping and service access.
Boiler Service Clearances – Applicable to all Boiler
Models:
Top = 24 in. (610 mm), Front = 24 in. (610 mm),
Left Side = 24 in. (610 mm), Right Side = 24 in.
(610 mm), Rear = 24 in. (610 mm)
The above clearances are recommended for
service access but may be reduced to the
Combustible Material Clearances provided:
