Wall-mounting the boiler
Remove boiler from crate
The boiler is heavy
. Use caution not to drop the boiler
or cause bodily injury while lifting and handling. Verify
that the boiler is securely attached to prevent possibility
of boiler falling after installation.
After the boiler is removed from the shipping carton,
DO NOT
allow the boiler to sit on its bottom. This would
cause pressure on protruding pipes, resulting in interior
damage. Either lay the boiler on its back on leave on the
styrofoam protective shipping base.
Do not drop boiler or bump jacket on floor or pallet.
Damage to boiler can result.
Cold weather handling — If boiler has been stored in a
very cold location (below 0°F) before installation, handle
with care until the plastic components come to room
temperature.
1. The WM97+ boiler is generally easier to handle and maneuver
after removing the shipping container.
2. Remove items 1, 2 and 3 in Figure 3. Remove trim kit and parts
from item 2.
3.
Leave the boiler resting on the styrofoam protective base
(item 5) and bottom cardboard cap (item 6), until ready to place
on the wall. If removing the boiler from the shipping base, rest
the boiler on its back, NOT on its bottom.
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).
The wall must be vertically plumb and capable of
carrying the weight of the boiler and any attached
piping components
.
The operating weights for wall-mountable boilers are:
WM97+70 or WM97+110:
140 pounds
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. The mounting
surface must not extend above the top of the boiler jacket.
2. Wood stud wall: Install bracket and spacer bar with lag screws (3/8”
x 3”) included in kit, only into the studs.
3. Metal stud wall: Secure bracket ad space bar to studs with 3/16-inch
toggle bolts and 3/16-inch flat washers (not included with kit).
Verify that the studs are suitable for carrying a wall-
mounted load. Some metal studs are not designed for
this purpose.
4. The boiler bracket must engage with the wall-mount bracket. Make
sure the brackets are not just resting edge to edge.
5. Mount the boiler on the wall following these instructions. Perform
all procedures given in the Boiler Manual on pages 1 through 7
before mounting the boiler.

Wall-mount bracket and spacer board
1 Studs — Pre-drill through the wall into the studs ¼ inch diameter x 3 inches
deep for 3/8-inch lag screws— Studs must be on 16-inch centers. If studs
are any other spacing, provide a secure, solid mounting surface on which to
attach the boiler wall-mounting bracket.
2 Wall-mount bracket.
3 Provide a spacer board pre-drilled with two clearance holes, spaced on 16
inch centers. Board must be
minimum
½ inch thick by 3½” high by 18
inches long. Clearance holes (2) should be ½” diameter for 3/8-inch lag bolts
or ¼” diameter for 3/16-inch toggle bolts.
