Introduction

Please follow these instructions. Failure to follow
instructions may result in:
▶ Damage or injury.
▶ Improper operation.
▶ Loss of warranty.
DANGER:
▶ The water heater must be installed by a qualified installer in
accordance with these instructions. If improperly installed,
a hazardous condition such as explosion or carbon
monoxide poisoning could result. Bosch
Thermotechnology Corp. is not responsible for improperly
installed appliances.
Common installation practice is to first determine the venting/

layout back to the heater.
