Ensure there is adequate clearances for mounting the boiler (details given in
installation instructions).
The wall mount bracket is designed for a stud spacing of 16 inches from
center. For other stud spacing a solid mounting surface must be provided by
the installer.
Do not mount the boiler to a hollow wall. Be sure to mount the boiler to the
studs only.
Mount the wall bracket using 4 5/16" lag screws. Ensure the bracket is level
when mounted.
Extreme care is needed to ensure the bolts are secured in the studs.
Hang the boiler on the bracket and secure the bottom of the boiler with two (2)
additional lag screws.
This boiler is heavy and awkward to lift. It is
recommended and safer to install the boiler with two
people. Use caution as to not drop this boiler which
could cause personal injury. Verify that the boiler is
securely mounted before leaving the boiler unsupervised.
