DV Series

Introduction
The new Bradford White DV water heaters are designed to provide reliable performance with
enhanced standard features. Design features include reliable standing pilot ignition system,
enhanced diagnostics, simplified servicing, and certified FVIR technology.
The DV water heaters use a combustion system where combustion air is drawn from the
outside of the building. The gas control maintains water temperature and gas flow. If a
situation outside of the normal operating parameters exists, the gas control diagnostic LED will
flash a code to identify an operational issue.
This service manual is designed to facilitate problem diagnosis and enhance service efficiency.
Please read the service manual completely before attempting service on this series of direct
vent water heaters.
How the Safety System Works
During normal operation, air for combustion is drawn into the water heater through the openings
in the jacket. This air travels down and around the combustion chamber and enters through the
back of the corrosion resistant combustion chamber. The air then mixes in a normal manner
with supplied gas and is efficiently combusted, producing very low NOx emissions.
