may be used in a power vent or direct vent
configuration. When used in a power vent configuration,
the water heater should be located in an area where there
is adequate air supply from inside the building for proper
combustion and ventilation. Please follow your local code
or NFPA54 where applicable.

negative pressure, there is a possibility of cold air drafting
back through the unit's heat exchanger. This situation
could lead to the freezing of the heat exchanger and
malfunction of the water heater.

The CASV
009-315
, Chimney Automation System™ is a demand
controlled exhaust system designed for commercial boilers and
water heaters in buildings where the exhaust is powered by a
chimney fan on the exterior of the building. It maintains a
precise draft by constantly adjusting the exhaust rate to meet
current needs. The concept can provide substantial operating
savings over gravity systems and offer significantly better draft
control which reduces emissions.
The CASV System can be combined with an MCAS, Modulating
Combustion Air-supply System™ and can also work with a
MODS, Modulating Over-draft Damper System™
