Install the wall-mount bracket
1. Locate the studs — must be on 16-inch centers. See previ-
ous instructions if studs are not on 16-inch centers.
2. Place the wall-mount bracket Figure 4, below on the wall,
using a level to align correctly.
3. Place the wall-mount bracket so the mounting slots are
centered over the studs.
4. Level the bracket and trace the outline of the screw slots
with a pencil.
7. Level the wall-mounting bracket. Then tighten lag screws
securely. For drywall or plaster lathe installations, avoid
tightening so much that the bracket digs into the wall
surface.
Place boiler on bracket
1. The wall-mount bracket must be installed before mounting
the boiler.
2. After installing the boiler on the mounting bracket, bend
down the two (2) tabs in order to secure boiler in place,
see Figure 5.

Wall-mounting requirements
DO NOT attempt to attach the wall mount bracket
using anchors or any means other than directly
securing to the wall studs (or equivalent wood
structure if studs are not on 16-inch centers).

Failure to comply with above and the procedure
given below could result in severe personal injury,
death or substantial property damage.
1. Stud spacing: Bracket holes are spaced for studs on 16-inch
centers. For other stud spacing, provide secure, solid mounting
surface on which to attach the boiler wall-mounting bracket.
2. Wood stud wall: Install bracket with lag screws (3/8” x 3”)
included in kit, only into the studs.
3. Metal stud wall: Secure bracket and spacer board to studs
with 3/16-inch toggle bolts and 3/16-inch flat washers (not
included with kit).
4. Concrete or block wall: Secure wall bracket with approved
bolts for that application.
Verify that the studs are suitable for carrying a wall-
mounted load. Some metal studs are not designed
for this purpose.
5. If the mounting wall has exposed studs, installer must provide
a backer board to mount boiler. Boiler cannot be leveled
without a backing surface.
6. Mount the boiler on the wall following these instructions.
The boiler mounting studs must engage with the wall-mount
bracket. Make sure the bracket is not just resting on the edge
of the mount
ing stud or washer. Perform all procedures given
in the Boiler Manual on previous pages before mounting
the boiler.
Install rubber bumpers to back of boiler
1. Remove supplied rubber bumpers from plastic bag and mea-
sure across 14 inches, and up 2 inches from the back of the
boiler bottom edge. Mark these two locations, and peel off
adhesive protection from the rubber bumpers, and mount
the two according to the directions in Figure 3.
2. DO NOT drill holes to mount the rubber bumpers

5. Remove the mounting bracket and drill holes 1/4” diameter
by 3 inches deep, centered on the screw slot outlines. (For
metal stud walls, using 3/16” toggle bolts, drill required
clearance holes.)
6. Position the wall-mount bracket on the wall. Insert and
loosely tighten the two (2) lag screws (or toggle bolts for
metal studs).
