Page 27

Check the type of gas and the gas inlet pressure before connecting the EverHot® water heater to the gas supply. If the gas supply type does not match the type shown on the water heater rating plate, then DO NOT connect the water heater. Contact your Bradford White supplier for the correct water heater.

GAS METER SIZE – NATURAL GAS ONLY

Be sure that the gas meter has sufficient capacity to supply the full rated gas input of the water heater, as well as the requirements of all other gas fired equipment supplied by the meter. If the gas meter is too small, ask the gas company to install a larger meter having adequate capacity.

GAS PRESSURE REGULATION

Minimum and maximum gas supply pressures are listed below: The minimum gas pressure specified below is required for the full input rating specified on the water heater rating plate.

Natural Gas: Minimum: 5.0 in. w.c.

L.P. Gas:

Minimum: 8.0 in. w.c.

Maximum: 10.5 in. w.c.

 

Maximum: 13.5 in. w.c.

Before placing the WATER heater in operation, check for gas leakage. Use soap and water solution or other material acceptable for the purpose of locating gas leaks.

WARNING

DO NOT use matches, candles, flame, or other sources of ignition for this purpose.

Note: After determining the length of pipe required, select the pipe size that will supply the CFH (cubic feet per hour) of gas required for the input rating of the gas appliances on the line. To determine the CFH required for the gas appliances on the line, use the formula, shown below. The heating value of the gas used may be obtained from a local gas utility.

CFH = Gas Input of Appliance(s) on the Line (Btu/hr)

Heating Value of Gas (Btu/Cu. ft)
