Gas Pressure Testing

Important: This water heater and its gas connection must be leak tested before placing the appliance in operation.

•If the code requires the gas lines to be tested at a pressure of 14” W.C. or greater, the water heater and its manual shut-off valve must be disconnected from the gas supply piping system and the line capped.

•If the gas lines are to be tested at a pressure less than 14” W.C., the water heater must be isolated from the gas supply piping system by closing its manual shut-off valve.

U.L. recognized fuel gas and carbon monoxide(CO) detectors are recommended in all applications and should be installed using the manufacturer’s instruc- tions and local codes, rules, or regulations.

Note: Air may be present in the gas lines and could prevent the burner from lighting on initial start-up. The gas lines should be purged of air by a qualified service technician after installation of the gas piping system.

Explosion Hazard

Have a qualified service technician make sure L.P. gas pressure does not exceed 13” water column.

Failure to do so can result in death, explosion, or fire.
