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.

5.Measure the gas pressures to see that these are within the specified limits below:

Supply Pressure:

Nat. Gas: Min.: 5 in. w.c., Max.: 10.5 in. w.c.

 

L.P. Gas: Min.: 8 in. w.c., Max: 13.5 in. w.c.

Manifold Pressure:

Nat. Gas: 2.0-3.3 in. w.c. High Fire, 0.5 in. w.c. Low Fire

 

L.P. Gas: 3.2-5.0 in. w.c. High Fire, 0.9 in. w.c. Low Fire

 

(High fire manifold pressures vary depending on the water

 

heater’s model)

6.Turn off the hot water faucets. Disconnect the electrical power to the water heater. Remove the pressure gauges and replace the plugs. Check for gas leaks around the plugs.

7.Replace the front control panel. Restore electrical power to the water heater

NOTICE

If the gas supply pressure is below the specified value, check the gas piping to ensure that it is the correct size for all the gas appliances on line. Check the supply pressure with all the gas appliances in operation. The manifold pressure will vary with the water flow rate. Several hot water faucets may need to be opened with the temperature control set on the highest setting in order to get maximum high fire manifold pressure. If the manifold pressure is below the specified value and there is sufficient water pressure and flow, be sure the inlet gas pressure is within the specified limits before attempting to adjust the manifold pressure.
