V Mounting The Boiler
A. Wall Mounting
1) 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 4s anchored to the studs.
2) 5/16” x 2” lag screws and washers are provided for mounting this boiler. These lag screws 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.
3) Make sure that the surface to which the boiler is mounted is plumb.
4) 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.
5) Once a suitable location has been selected for the boiler, and any needed modifications have been made
to the wall, use Figure 5.1 to locate holes “A” and “B”. Make sure that 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.
6) Cut the opening/s in the wall for the vent system. The recommended hole diameter is 4-3/8” for
60/100mm coaxial pipe and 5-3/8” for 80/125mm pipe.
7) Attach the wall hanging hook using the 5/16” x 2” lag screws and washers, or other suitable anchors as
appropriate (Figure 5.2). Make sure the hook is level.
8) Hang the boiler on the wall hook as shown in figure 5.2.
9) If not already done in Step (4) locate and drill holes “C” and “D” using the ob-round slots in the bottom
mounting flange. Secure the bottom flange to the wall using the 5/16”x 2” lag screws, or other fasteners as
appropriate (figure 5.2).
10) Verify that the front of the boiler is plumb. If it is not, install washers at holes “C” and “D” between the
bottom mounting flange and the wall to adjust.
10) See Section VII (Venting) for instructions on attaching the vent system to the boiler.
B. Floor Mounting
This boiler may be mounted on the floor using an optional pedestal kit available from Crown. Follow the
instructions provided with this kit to assemble the pedestal, and attach it to the boiler. When this pedestal is used,
the boiler may be installed directly on a non-carpeted combustible floor.
CAUTION
This boiler weighs approximately 133 pounds:
• Two people are required to safely lift this boiler onto the wall mounting hook.
• Make sure that wall mounting hook is anchored 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 requirements for supporting this boiler. These
local requirements take precedence over the requirements shown below.
