tion. If the error is not corrected, contact Bosch Ther-

8.2 Gas conversion

If you move to a region that uses a diferent type of gas

or if the local gas supply is converted, replacement of

the gas manifold and adjustment of the appliance will be

necessary. This work must be performed by either

Bosch or a qualified service agency and will be charged

foreven during the warranty period. The qualified

installer will also be responsible for purchasing the gas

conversion kit directly from the manufacturer. For more

information, contact Bosch Thermotechnology Corp. at

1-866-330-2730.

The following parts are supplied in the conversion kit.

These items will replace the existing parts that are cur-

rently installed in the unit. Make sure that all parts are

replaced and properly installed by a qualified service

agency.

• Manifold plate

•O-ring

• Conversion Kit Label.

After the necessary parts have been replaced on the

unit, the remote controller is then used to adjust the set-

tings on the water heater for use with the proper gas

type. The gas pressure values at both the gas supply

inlet fitting and at the manifold inlet on the unit are veri-

fied by the installer. Proper adjustments will be made to

ensure safe and eficient operation. Once this is com-

pleted, a final gas leak check will be performed to con-

firm that all parts have been securely installed.

A request for service may be rejected if

the water heater is installed in a location

where working on the unit may be danger-

ous. Contact a plumber.

Warning:

The gas conversion kit shall be installed

by a qualified service agency

in ac-

cordance with the manufacturer’s in-

structions and all applicable codes and

requirements of the authority having ju-

risdiction. The information in the instruc-

tions must be followed to minimize the

risk of fire or explosion or to prevent

property damage, personal injury, or

death. The qualified service agency is

responsible for the proper installation of

this kit. The installation is not proper

and complete until the operation of the

converted appliance is checked as

specified in the manufacturer’s instruc-

tions supplied with the kit.

1) A qualified service agency is any individual, firm, corpo-

ration, or company which either in person or through a

representative is engaged in and is responsible for the

connection, utilization, repair or servicing of gas utiliza-

tion equipment or accessories; who is experienced in

such work, familiar with all precautions required, and has

compiled with all of the requirements of the authority

having jurisdiction.

Warning:

Before the gas conversion is performed,

verify the proper gas conversion kit with

your water heater model on the table
