Wall-mounting the boiler
Verify that the studs are suitable for carrying a wall-
mounted load. Some metal studs are not designed for
this purpose.
4. If the mounting wall has exposed studs, installer must provide a
backer board to mount boiler. Boiler cannot be leveled without a
backing surface.
5. 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
stud or washer. Perform all procedures given in the Boiler Manual
on previous pages before mounting the boiler.
Install the wall-mount bracket (by installer)
1. See Figure 4 .
2. Locate the studs — must be on 16-inch centers. See previous
page instructions if studs are not on 16-inch centers.
3. Place the wall-mount bracket (Figure 4, item 2) on the wall, using
a level to align correctly.
4. Place the wall-mount bracket so the mounting slots are centered
over the studs.
5. Level the bracket and trace the outline of the screw slots with a
pencil.
6. 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.)
7. Position the wall-mount bracket on the wall. Insert and loosely
tighten the two lag screws (or toggle bolts for metal studs).
8. 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. See Figure 5 . The wall-mount bracket must be installed before
mounting the boiler.
2. Measure 22 1/2 inches below the bottom edge of the wall-mount
bracket (item 2). Strike a line or place a piece of masking tape
with its top edge even with the 22 1/2-inch mark. (This line, or
tape, will indicate whether the boiler has been properly seated
onto the wall-mount bracket.)
Figure 4 Wall-mount bracket and studs
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.

Part number 550-100-191/0917
as-fired water boiler —
70/110/155
(continued)
The boiler is heavy, and requires two
people to lift and place. Wear non-slip
leather gloves to prevent possibility of cuts
from sheet metal edges.
The jacket door can be left in place when
handling the boiler, but the boiler must
ONLY be lifted by the bottom and rear of
the sheet metal housing — NOT by any pipe
mounting
or plastic part.
3. Obtain assistance to lift the boiler into
position.
4. Lift the boiler high enough that its mounting studs
( Figure 6, page 12 , item 3) will be above the wall-
mount bracket (item 2).
5. Let the rear of the boiler slide against the lag screw
heads as you lower the boiler into place. The V-groove
will help guide the studs into the slot.
Figure 5 Place boiler on wall-mount bracket
1 Studs — Pre-drill through the wall into the studs ¼ inch diameter x 3
inches deep — 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 — secure wall mount bracket to wall as instructed
on previous page.
3 Boiler mounting studs (Figure 6 back of boiler) — The V-groove on the
wall-mount bracket will help guide the studs into the slots. The studs
are attached to the back of the boiler.
