WARNING

Exposure to a higher gas supply pressure may cause damage to the control, resulting in explosion or fire. Consult your local gas supplier and gas authorities. DO NOT PUT INTO SERVICE

IF OVER-PRESSURIZATION HAS OCCURRED.

Use gas piping of adequate sizing to ensure full gas input. All piping must comply with all local codes. In the absence of local codes, piping must comply with the rules stated by the applicable National Fuel Gas Codes. Final connection to the water heater is made using 1/2" N.P.T. pipe.

•A manual gas shut-off valve shall be installed in the gas line near the water heater. A union is recommended for ease of service.

•To trap dirt or foreign material in the gas supply, a dirt (drip) leg shall be installed in the piping.

•Apply joint compound (pipe dope) to the male ends of the threads before joining pipe sections. Use only compounds that are compatible with natural gas and propane fuels. To prevent damage to the gas valve, do not over-tighten.

Purging Caution:

Gas line purging is required to eliminate air from the piping system. Purging should be performed by persons experienced in this type of gas service. Do not purge in confined areas or space where ignition may occur. To avoid risk of fire or explosion ensure the area is well-ventilated and all sources of ignition are de- activated. Contact your local gas authority for local requirements.

IMPORTANT: Disconnect the water heater from the gas piping during any high pressure testing above 0.5 p.s.i. Perform a leak test at normal gas pressure on all fittings after all connections have been made and the gas has been turned on. Soap test all connections of the gas system - bubbles indicate leaks.

Gas Pressure

GSW Water Heating Company recommends that the gas supply pressure as measured on the inlet side of the water heater control, be set at 7.0 inches water column for natural gas and 11.0 inches water column for propane gas.

Electrical Supply

A three-wire cord and plug is provided with this water heater. The plug shall be connected into an electrically grounded, 120 VAC, 60 Hz, 12 Amps, fused receptacle. The electrical supply

must meet the minimum provisions as stated in the National Electrical Code for U.S. customers and in the Canadian Electrical Code for Canadian customers.

The electrical controls used inside the thermostat/gas valve mounted on this water heater is polarity sensitive. Ensure that the electrical supply is properly connected in the receptacle box. Failure to connect properly will cause the unit not to function (See Figure 10).
