SAFETY
INSTRUCTIONS
The Hubbell water heaters weigh 90 to 100 lbs (40.8 to 45.4 kg) and
must be securely attached to the wall. Mounting hardware is
included and should be used to mount the unit.
2. Level upper bracket (2) and attach it to the mounting
block with at least four appropriately sized wood
screws (do not use drywall screws).
CAUTION
Lifting Hazard
According to the National Institute for Occupational
Safety and Health, the recommended maximum safe
lifting weight is 51 pounds, with all lifting conditions perfect—
minimal forward reach, steady load close to the body, straight back,
load between knees and shoulders, and good grips. To avoid
personal injury, always use these proper lifting techniques and use
two people to move the water heater which weighs 80 pounds.
3. With assistance, hang the unit on the upper wall
bracket, interlocking bracket (1) on the back of the unit
and wall bracket (2).
4. Install two appropriately sized wood screws in lower
bracket (3) to secure the unit to the wall.
5. Make sure the unit is plumb and level and tighten the
four sheet metal screws on bottom bracket (3). When
properly installed, there should be a 5/8” air space
between the back of the water heater and the mounting
blocks.
Plywood Installation Method
1. Mount a piece of 3/4” plywood (at least 32” high x 20”
wide) to the wall.
a. In wood or steel construction, use adequate wood/
metal screws and secure the plywood with at least
two screws in each vertical wall stud.
b. In concrete block or solid concrete wall construction,
attach the plywood with at least four masonry
screws or suitable masonry wall anchors.
