This boiler weighs as much as 126 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.
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 4's 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" sheathing. 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.
The wall mounting hook is used to secure the boiler to the shipping pallet. Remove this hook from the pallet and
secure to the wall 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.
7.
Hang the boiler on the wall hook as shown in Figure 5.2.
8.
If not already done in Step (5) locate and drill holes "C" and "D" using the obround 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).
9.
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.
