The water heater must be full of water and the system fully purged BEFORE powering the water heater. Applying power to the water
heater when it is not full of water 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.
I. 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

damage, serious personal injury, or death. Such damages ARE NOT covered by water heater warranty.
