Table 5 : maximum flue system pipe lengths
FLUE OUTLET
• Use only one flue pipe diameter on an installation.
• Recommended minimum flue is 1m.
* Mentioned lenghts only apply when :
- no elbow installed immediately after flue and inlet
- successively installation of several elbows without straight pipe
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.
Attention :
Single wall flue pipe exposed to cold air or run through unheated
areas should be insulated. Where condensation is unavoidable,
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.
The port must be at least 450 mm away from the air heater flue
connection socket. Follow the flue pipe manufacturers instal -
lation instructions for making joints, including connections to
the air heater, for passing through a building element and for
support requirements.
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.
FLUES FOR POWER VENTED INSTALLATIONS
(type B appliances)
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.
