Review all of the instruc ons
before you begin work.
Improper installa on can
damage the water heater, your home
and other property, and can present
risks of serious injury or death.

following tools and supplies:
Plumbing tools and supplies appropriate
for the type of water pipes in your home
Threaded connectors (Figure 1) for
the cold and hot water pipes
For homes plumbed with plas c
pipe, use threaded connectors
