ii. Pre-installation & Boiler Mounting (continued)
6. Boiler Wall Hung Installation:
a. If the boiler is installed on a framed wall,
minimum acceptable framing is 2 x 4 studs on
16" centers. The boiler mounting holes are on
16" centers for installation between two studs
at the standard spacing. In cases where the
boiler cannot be centered between the studs, or
where the studs are spaced closer than 16" apart,
the boiler may be anchored to ¾" plywood or
horizontal 2 x 4's anchored to the studs.
CaUTiOn
alpine boiler approximate dry weights:
aLP080W – 98 lbs; aLP105W – 112 lbs;
aLP150W – 16 lbs: aLP210W – 150 lbs
Two people are required to safely lift these
boilers onto the installed wall mounting
bracket.
Make sure that wall mounting bracket is an-
chored to a structure capable of supporting
the weight of the boiler and attached piping
when filled with water. Jurisdictions in areas
subject to earthquakes may have special re-
quirements for supporting these boilers. Such
local requirements take precedence over the
requirements shown below.
b. Locate Wall Mounting Bracket Kit carton (p/n
102988-01) enclosed inside boiler carton. The
kit contains Wall Mounting Bracket, Bottom
Securing Bracket, (4) 5/16" x 2" long hex head
lag screws, (4) 5/16" flat plated washers and (2)
#8 x ½" Phillips round head sheet metal screws.
c. 5/16" x 2" lag screws and 5/16" plated washers
are intended for mounting the boiler directly
onto studs covered with ½" sheet rock. When the
boiler is attached to other types of construction,
such as masonry, use fasteners capable of
supporting the weight of the boiler and attached
piping in accordance with good construction
practice and applicable local codes.
d. Make sure that the surface to which the boiler is
mounted is plumb.
e. Before mounting the boiler, make sure that wall
selected does not have any framing or other
construction that will interfere with the vent pipe
penetration.
f. Once a suitable location has been selected for the
boiler, and any needed modifications have been
made to the wall, use Figure 2C to locate and
layout holes "A" and "B". These holes must be
positioned on mounting stud centers, if the boiler
is installed on a framed wall. Make sure that
1
the horizontal centerline of these holes is level.
Holes "C" and "D" may also be drilled at this
time, or after the boiler is hung on the wall. If the
5/16 x 2" lag screws are used, drill 3/16" pilot
holes.
g. An alternate way to locate/mark holes "A"
and "B" is to use template P/N 102986-01
enclosed into Vent Part Carton [P/N 102981-
01 (ALP080W/105W) or, P/N 102981-02
(ALP150W/210W)], which can be found inside
boiler carton.
CaUTiOn
The outer edges of the template represent
minimum side, top and bottom clearances to
combustible material. if the template needs to be
cut to fit into a selected location, it would indicate
the minimum clearances to combustible material
are not met.
h. Attach the wall hanging bracket using the 5/16"
x 2" lag screws and 5/16" plated washers, or
other suitable anchors as appropriate (Figure
2D). Make sure the bracket is level.
i. Attach Bottom Securing Bracket to boiler air box
with two #8 x ½" Phillips round head sheet metal
screws. Refer to Figure 2D for details.
j. Hang the boiler on the installed wall bracket as
shown in Figure 2D.
k. If not already done in Step (4) locate and drill
holes "C" and "D" using the ob-round slots in
the Bottom Securing Bracket. Secure the Bracket
to the wall using the 5/16" x 2" lag screws
and 5/16" plated washers, or other fasteners as
appropriate (Figure 2D).
l. Verify that the front of the boiler is plumb. If it
is not, install shims (installer provided) at holes
"C" and "D" between the Bottom Securing
Bracket and the wall to adjust.
CaUTiOn
When positioning the template in the desired
location on the wall insure that the minimum
clearances to combustible
adjacent walls and ceiling are maintained. Consult
Figures 2a thru 2C in this manual. Be sure to
allow space at the boiler left side for gas and
water connections, as well as for access to the
condensate trap and boiler controls for servicing.
m. Remove Access Panel and Access Panel Gasket
from zip lock plastic bag (placed inside 102981-
01 or 102981-02 Vent Kit carton).
