Installation / Operation Instruction Manual

Water Connections continued-

If this water heater is installed in a closed water supply system, such as one

having a back-flow preventer in the cold water supply, provisions must be made

to control thermal expansion. DO NOT operate this water heater in a closed

system without provisions for controlling thermal expansion. Your water

supplier or local plumbing inspector should be contacted on how to control this

situation.

After installation of the water lines, open the main water supply valve and fill the

water heater. While the water heater is filling, open several hot water faucets

to allow air to escape from the water system. After a steady stream of water

flows through the faucets, close them and check all water connections for

possible leaks. NEVER OPERATE THE WATER HEATER WITHOUT FIRST

BEING CERTAIN IT IS FILLED WITH WATER.
