WARNING: Do not attempt to convert this water heater for use with a different type of gas other than the type shown on the rating plate. Such conversion could result in hazardous operating conditions.

Safety Instructions

Gas Supply

The branch gas supply line to the water heater should be clean 1/2″ black steel pipe or other approved gas piping material.

A ground joint union or ANSI design certified semi-rigid or flexible gas appliance connector should be installed in the gas line close to the water heater. A manual gas shut-off valve should be at least 5 ft. above the floor and readily accessible.

Compound used on the threaded joints of the gas piping must be of the type resistant to the action of LP gas. Use compound sparingly on male threads only.

A sediment trap should be installed at the bottom of the gas line.

Do not use excessive force (over 31.5 ft lbs.) in tightening the pipe joint at the thermostat inlet, particularly if teflon pipe compound is used, as the valve body may be damaged.

The inlet gas pressure to the water heater must not exceed 14″ w.c. for natural or LP gas. For purposes of input adjustment, the minimum inlet gas pressure (with main burner on) is shown on the water heater rating plate. If high or low gas pressures are present, contact your gas supplier for correction.

Installation Instructions Operating

WARNING: Never use an open flame to test for gas leaks, as bodily injury, property damage or death could result.

Leak Testing

The water heater and its gas connections must be leak tested at normal operating pressures before it is placed in operation.

Turn on the manual gas shut-off valve near the water heater.

Use a soapy water solution to test for leaks at all connections and fittings. Bubbles indicate a gas leak that must be corrected.

The factory connections to the thermostat should also be leak tested after the water heater is placed in operation.

Troubleshooting Tips

High Altitude…

Ratings of gas appliances are based on sea level operation and need not be changed for installations at elevations up to 2,000 feet.

For installations above 2,000 feet, the input must be reduced per the National Fuel Gas Code for each 1,000 feet above sea level. Contact the local gas supplier for more information.
