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. (3.486 kPa) or greater, the water heater and its manual shut-off valve must be discon- nected 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. (3.486 kPa), the water heater must be isolated from the gas supply piping system by closing its manual shut-off valve.

Nationally listed/recognized fuel gas and carbon monoxide(CO) detectors are recommended in all applications and should be installed using the manufacturer’s instructions 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 person make sure that the L.P. gas operating pressure does not exceed 13” water column (3.237 kPa). Examples of a qualified person include licensed heating personnel, authorized gas company personnel, and authorized service personnel.

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