• Manometer
• Multi-meter
• Combustion Gas Analyzer
4.2

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/combustion air point of termination, then
design the piping layout back to the heater.
4.3

Venting

DANGER:
▶ Do not reduce the exhaust or combustion air vent
pipe sizes.
▶ Do not common vent with any other vented appliance
or stove.
▶ Do not use Type-B vent as the actual exhaust vent
system for the appliance.
DANGER: Flue gas poisoning!
▶ Failure to vent the exhaust gases to the outside (see
table 5 for proper material) may result in dangerous
flue gases filling the structure in which it is installed.
NOTICE:
▶ In areas where outside temperatures routinely come
close to freezing, sealed combustion operation is
required. Concentric termination or separate
terminations for combustion and vent, must be
installed on the same wall or roof surface; however,
never facing the direction of prevailing winds. Failure
to do so may result in heat exchanger freezing and
bursting. This failure is not covered under the
manufacturer's warranty.
WARNING: Appliance malfunction!
▶ Protect the exhaust and inlet from leaves and debris
by installing a screen on the end of the termination.
¼ " mesh minimum opening recommended on
screen.
