outside of the room containing the appliance. The combustion air is drawn directly from the room.
C13
Closed Flue
An appliance connected to either a concentric or twin-pipe flue system with a Horizontal flue terminal.
Both the air inlet and flue exhaust must be in the same pressure zone.
C33
Closed Flue
An appliance connected to either a concentric or twin-pipe flue system with a Vertical flue terminal. Both
the air inlet and flue exhaust must be in the same pressure zone.
C43
Closed Flue
An appliance connected to a common air inlet and flue exhaust system, which is designed for more than
one appliance. This common system has a single air inlet and flue exhaust and is part of the building not
the appliance.
C53
Closed Flue
An appliance connected to a twin-pipe flue system with a Horizontal or Vertical flue terminal. Both air
inlet and flue exhaust may be in different pressure zones.
C63
Closed Flue
An appliance intended to be connected to a separately approved and marketed system for the supply of
combustion air and discharge of combustion products (i.e. other than that supplied by the water heater
manufacturer).
All installations should comply with the requirements of:

c. Horizontal flue terminations (other than for fan dilution systems) must not be installed for any single
appliance or group of appliances with a total nett input exceeding 333kW net heat input.
d. For any single appliance or group of appliances with a total net heat input exceeding 333 kW, the
general requirements of IGEM/UP/10 Edition 4 +A: 2016 shall apply and approval must be sought
from the Local Authority prior to commencement of the installation.
3. The Clean Air Act for installations exceeding 333kW nett input.
