iii. Pre-installation and Boiler Mounting
(continued)
H. Boiler Stacking
1. For installations with unusually high space heating
and/or domestic hot water heating loads, where
employing multiple boilers will offer the benefits of
greater operational efficiency, floor space savings
and boiler redundancy, boilers may be installed
stacked maximum one boiler on top of another.
Refer to Table 6 “Alpine Boiler Model Stacking
Combinations” for details.

2. To field assemble individual Alpine boilers into a
stackable configuration, use the steps below:
a. Position the bottom boiler first. Refer to Sections
II “Unpacking Boiler” and III “Pre-Installation
& Boiler Mounting” of the manual for details.
Always position higher input boiler model as
bottom boiler.
b. Each Alpine boiler is factory packaged with
2 stacking boiler attachment brackets (P/N
101679-01) and the bracket mounting hardware
[six (6) self-drilling hex washer head plated #8
x ½” long screws, P/N 80860743]. Locate and
remove the brackets and the hardware. The
stacking boiler attachment bracket has three
7/32” diameter holes punched in a triangular
pattern. See Figure 5 “Boiler Stacking”.
c. Alpine boiler left and right side panels have a
series of dimples at panel top and bottom. These
dimples are positioning dimples for stacking
boiler attachment bracket mounting screws. Side
panel bottom positioning dimples are evenly
spaced from boiler front and back, while side
panel top positioning dimples follow specific
pattern to compensate for Alpine boiler model
variable depth.
d. Position the upper boiler on top of the bottom
boiler and align boiler front doors and sides flush
with each other.
• Place first stacking boiler attachment bracket
onto the upper boiler left side panel, at the
panel lower left corner and align bracket two
upper holes with corresponding side panel
lower dimples.
