performed.
D. Important Notice
It is extremely important that whenever work is performed on
the plumbing system that either:
• The water heater is powered off, or,
• The water heater is valved off and isolated from the
plumbing system.
Failure to take these measures could result in a dry-firing
condition.
The water heater must be full of water and the system fully
purged BEFORE powering the water heater. Performing any
work in the plumbing system without either powering off
the water heater or isolating the water heater through the
use of shut-off valves could result in a condition referred to
as "dry-firing". Dry-firing the water heater will damage the
heat exchanger, and could result in property damage, serious
personal injury, or death. Such damages ARE NOT covered by
water heater warranty.
