Notes
1. A properly installed flue system is essential for the
safe and efficient operation of a Rayburn.
2. If you are planing to use an existing masonry chimney,
it must first be inspected, tested and swept.
3. Our product installation instructions are available for
downloading on our website, www.rayburn-web.co.uk.
4. Most Rayburn dealers are able to arrange for home
surveys and offer pre-installation advice.
5. The installation and commissioning of range cookers
must be carried out by a competent person and is
‘notifiable work’ to the local authority.
6. Flues and chimneys need routine inspection and cleaning,
particularly solid fuel or wood burning models.
Balanced flue
A balanced flue (sometimes more correctly referred to as a room-sealed appliance) can be a solution where a property has
no masonry chimney and a freestanding flue-pipe would be inappropriate.
It uses two twin pipes or ducts coming straight from the back of the cooker through the wall to outside. One tube brings
a fresh air supply into each of the burners, whilst the other discharges the products of combustion. On oil-fired models
this takes the form of two rectangular ducts, whilst the gas-fired cooker has two concentric tubes. Terminals are externally
covered by a protective cage.
Oven venting is still a product feature and benefit. A separate copper pipe travels from the ovens to outside to remove
cooking smells and condensation, sometimes assisted by a small electric fan on the oil-fired models.
Models using balanced flues:
Oil - 400 central heating models, 680KCD
Gas - 480CD
Power flue
A power flue may be the answer for properties where there is no conventional chimney and offers the flexibility for the cooker
to be sited on an external or internal wall, even within an island or peninsular setting.
It uses a single, stainless steel flue-pipe, diameter 54mm. A variable speed, low voltage electric fan is fitted externally to
provide the necessary suction.
A basic flue installation kit is supplied with the product, suitable for most installations up to 3m. Additional flue-pipe fittings
and fastenings are available including 90 and 45 degree angle bends to allow flexibility of the flue route.
