FLUES FOR POWER VENTED INSTALLATIONS
(type B appliances)

FLUE OUTLET
Venter outlet attachment requirements:
Depending on the size of flue pipe as determined in Table 5,
attach either the flue pipe directly to the collar or a taper-type
connector.
If the air heater is to be installed as a type B appliance, air
for combustion will be taken from within the space where the
heater is installed. Ensure that an adequate air supply for
combustion and ventilation is provided within the building in
accordance with BS6230/BS5440 plus other relevant regula-
tions & rules in force.
Gasket sealed single wall flue seamless aluminium or stainless
steel pipes are required. All joints must be sealed to prevent
products of combustion from leaking into the building. If the
flue passes through a combustible element of the building it
must be enclosed by a sleeve of non-combustible material and
separated from the sleeve by a minimum of 25 mm air break.
The temperature of any combustible material near to the flue
must not exceed 65°C when the heater is in operation. The flue
must be at least 150 mm away from any combustible material.

Warning:
Single wall flue pipe exposed to cold air or run through
unheated areas should be insulated to avoid condensation.
Provision must be made for the condensation to flow
freely to a point to which it can be released, i.e. a drain
or gully. The condensation drain from the flue must be
constructed from non-corrodible material not less than
20 mm diameter. Copper or copper based alloys must not
be used for condensation drains.
For testing, the flue pipe should include a sealable test port.
Ideally the test port should be at least 450 mm away from the
air heater flue connection socket. However if a concentric flue
fitting is attached directly to the connection sockets then the
combustion should be tested through the flue outlet collar via a
drilled test port which must be securely plugged on completion.
Follow the flue pipe manufacturers installation instructions for
making joints, including connections to the air heater, for pass-
ing through a building element and for support requirements.
