[]

Securely attach the water heater to the wall
using the brackets located at the top and

bottom of the water heater.

[]

Ensure that the attachment strength
is sufficient to support the weight. Refer
to the weight of the water heater in
the Specification Guidelines. Four mounting
screws with 200 Ib tensile load capacity are
required at a minimum.

Wall installation

brackets

[] ON WOOD OR SIDING: When attaching

the unit to wood or siding, mount 2 boards
suitable for anchoring to wall studs, between

the studs. You can do this before the wall has

wall is required in case the wall is not strong
enough to hold the water heater. Do not mount
to drywall unless mounting screws are secured

in wall studs.

Hake sure the location of the water heater allows
for easy access and operation.

Wall studs should be utilized when mounting the
water heater to the wall. On masonry or concrete
wall, use concrete anchors or lag bolts.

NOTE: Screws provided must fasten securely and
directly into wood. If screws go through siding or
insulation and do not fully engage, installer must
supplg correct screws.
