Section III. Installer Check-out and Start-up General: 33 Some of the following procedures will require the heater to be operating. Full lighting and shutdown instructions are included on the lighting and operating label affixed to the inside of the front access panel. The heater automatically lights in response to a call for heat, and automatically shuts down when that call for heat is satisfied. Water must be flowing through the heater during operation. Check that the pump is operating and the system is filled with water and purged of all air prior to starting the heater.

The heater and its individual shutoff valve must be disconnected from the gas supply during any pressure testing of that system at test pressure in excess of ½ psig (3.45 kPa). The heater must be isolated from the gas sup- ply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressure equal to or less than ½ psig (3.45 kPa). Gas supply line must be capped when not connected. After pressure testing, reconnect the gas piping to the gas valve. Turn gas supply "ON" and test all pipe and tubing joints for leaks. Use a soap and water solution. USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Pomona, CA Clemmons, NC Nashville, TN Tel: 908-351-5400 www.haywardpool.com
