GAS METER SIZE –NATURALGAS 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: 6.0” w.c.	L.P. Gas:	Minimum: 10.0” w.c.
Maximum: 10.5” w.c.		Maximum: 13.5” 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 cubic feet per hour of gas required for the input rating of the gas appliances on the line.

The formula for figuring the cubic feet per hour required is:

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

Heating Value of Gas (Btu/Cu. Ft.)

The heating value may be obtained from the local natural gas utility

INITIAL OPERATION AND TESTING (INSTALLER ONLY)

1.Open the gas and water supply valves to the water heater.

2.Check for water and gas leaks. Use soap solution to check for gas leaks.

3.To check inlet supply pressure, remove the 1/8” NPT plug on the gas inlet supply fitting just below the bottom casing and install a barb fitting for attaching a hose to a manometer. For checking the gas manifold pressure, the plug is located just below the gas manifold connection inside the control panel.

4.Turn power on (after completing electrical connections – refer to Section VII, “Electrical Connections”) and fully open a hot water tap.
