Installation instructions
4.6.4 Recommended Vent Configuration Examples
Below are approved examples of vertical and horizontal venting
installations.
NOTICE:
Using a single pipe vent in cold climates puts the water heater
at risk of freezing, as negative air pressure is common in
buildings during cold weather. This situation will pull cold air
through the heat exchanger and can lead to damage and a water
leak and is not covered by the product's warranty. In the event
of negative air pressure causing back drafting contact Bosch for
information.
