Placing boiler — wall-mounting option
Prepare boiler for wall mounting
1. Remove the jacket front panel. This will simplify lifting and han-
dling the boiler when mounting.
2. When piping will be routed out the top of the boiler, no special
preparation is needed other than that given in this manual.
Install wall-mount bracket
1. Locate studs.
2. Place the wall-mount bracket on the wall, using a level to align
correctly.
3. Place the 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.
5. Remove 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. See Figure 47, page 50 . Position bracket on wall. Insert and loosely
tighten the two lag screws (or toggle bolts for metal studs).
7. Level the bracket. Then tighten screws securely. For drywall or
plaster lathe installations, avoid tightening so much that brackets
dig into wall surface.
Place boiler on bracket
1. Measure 30 / inches below the bottom edge of the wall-mount

a line or place a piece of masking tape on the wall with its top
edge even with the 30-inch mark. (This line, or tape, will indicate
whether the boiler has been properly seated onto the wall-mount
bracket.)
2. Obtain assistance to lift the boiler into position:
a. Lift the boiler high enough that its rear bracket will be above
the wall-mount bracket.
b. Let the rear of the boiler slide against the lag screw heads as
you lower the boiler into place.
c. When the brackets are engaged correctly, the bottom of the
boiler enclosure will be at or near the pencil line, or tape, you
applied in step 1.
d. If the boiler does not slide down close to the mark, or tape,
adjust until the brackets properly engage.
