EHS.D0500.5010.400

Closed

Air supply
from outside

Type C43. A type C4 appliance incorporating a
fan upstream of the combustion chamber/heat
exchanger.

C53

Closed

Air supply
from outside

*Separate air supply duct
*Separate flue gas discharge duct.
* Air supply inlet and flue gas outlet at different

air pressure zones. But not at opposite walls.

See: Typical examples - example F

C63 - example

Closed

Air supply
from outside

* Appliance sold without flue/air-inlet ducts
* The flue gas parts are not part of the boiler.
The water heater is intended to be connected to
a separately approved and marketed system for
the supply of combustion air and discharge of
combustion products.
Condensate is allowed to go to the boiler.
* Air supply inlet and flue gas outlet not at oppo-

site walls
