GENERAL INFORMATION

One pound of gas pressure is equal to 27.7 inches water column pressure

Inches of Water Column X .036091 = PSI

Inches of Water Column X .073483 = Inches of Mercury (Hg.)

Centimeters = Inches X 2.54

MM (millimeters) =Inches X 25.4

Meters = Inches X .0254

Doubling the diameter of a pipe will increase its flow capacity (approximately) 5.3 times.

Construction: Tank is constructed of steel.

The inside of the tank is constructed of a glass lining bonded to the steel. This prevents water to metal contact and rusting of the tank.

An anode rod will be installed within the tank. The hex-head plug end of the anode is visible on the top of the water heater. This metal rod offers secondary protection of the tank against corrosion where the application of glass is not possible (threaded tank openings). These areas will have small areas of water to metal contact.

All water heaters will contain at least one thermostat (to operate the heater) and one high limit (to prevent water temperatures approaching the “steam” level).
