Installation instructions

3.10 Electrical connections

Warning: For safety reasons, disconnect the power supply cord to the heater before any service or testing is performed.

Warning: This heater must be electrically grounded in accordance with the most recent edition of the National Electrical Code NFPA 70. In Canada, all electrical wiring to the heater should be in accordance with local codes and the Canadian Electrical Code, CSA C22.1 Part 1. Do not rely on the gas or water piping to ground the metal parts of the heater.

The 2400 E requires an electrical power supply from a 120VAC / 60Hz circuit (with a dedicated outlet) and must be properly grounded.

A means for switching of f the 120VAC power supply must be provided.

The heater is wired as shown in the wiring diagram (chapter 7, Fig. 44).

3.12 Recirculation application

Since recirculation through the heater is not permissible, the following drawing is provided to outline a proper recirculation application using the Aquastar water heater with an Ariston minitank water heater. This schematic is for illustration only and must not be used for actual installation without appropriate engineering and technical advice from a properly licensed professional in the locality where the installation is made.

The use of a small electric mini-tank water heater (4-6 gallon size) should be used for this application and designed so the pump will circulate the water through the mini-tank and the building's hot water return loop only. Timed or thermostatically controlled operation of the pump is commonly done. The 2400 E must be supplied with cold water only and plumbed in line before the mini-tank water heater. Contact Bosch Water Heating if further information is needed.
