Hot Water Generator Installation and Operation Manual

2Installation (continued)

￿WARNING Do not install a valve between the water heater relief valve and the vent.

Doing so could cause serious injury or death if the pressure relief valve released and the manual valve was closed. This would cause excessive buildup of pressure in the water heater which could result in an explosion.

Connecting the circulation pump and electrically activated controls

Lochinvar Hot Water Generators are equipped with a circulation pump. If the unit being installed is so equipped, the correct power source(s) must be connected. The circulation pump must run all the time. Wire this pump to a correctly sized disconnect switch per local codes.

￿WARNING The combination of electricity and water can pose a very dangerous

situation. Assure that all electric power has been turned off before attempting any installation or maintenance procedures.

Reference the wiring CAD drawing included with the unit, or the installation instructions contained in the Installation Manual for the component, for specific wiring instructions.

Completing installation

Installation of the Lochinvar Hot Water Generator is now complete. All documentation supplied with the unit should be passed along to maintenance personnel for future reference.

NOTICE

All power connections should be performed by trained, certified electricians.
