2.3Unpacking the 2400 E heater

Before installing the unit, be certain you have the correct heater for your type of Gas - Propane or Natural Gas. Identification labels are found on the shipping box, and on the rating plate sticker which is located on the right side panel of the cover.

•Exhaust vent adaptor (with 4 screws and gasket provided)

•Condensate drain tube kit

•Combustion air inlet adaptor (with 3 screws and gas- ket provided)

•Plastic decal shields for covering front cover screws and control panel, installer should affix these decals to the front of the unit after installation is complete. See Fig. 3

•Installation manual (replacement manuals can be downloaded at www.boschhotwater.com)

•Product registration card

•Energy Guide label.

Please complete and return the enclosed product registration card.

The 2400 E is not approved or designed for:

•Manufactured (mobile) homes, RV's, boats or any mobile installation.

•Heating or other recirculating/pumping applications*

•Solar/preheat backup or high temperature booster use.

*This includes domestic hot water circulator pump loop systems that may be installed in home hot water system prior to installing this unit. An approved recirculation design can be found in chapter 3.9. The use of a small electric mini-tank water heater (4-6 gallon size) must be used for this application and designed so the pump will circulate the hot water in the mini-tank only and through the building's hot water return loop (timed or thermostatic controlled operation of the pump is commonly done). The 2400 E must be plumbed in line before the mini-tank water heater and supplied with cold water only. Contact Bosch Water Heating if further instruction is needed.
