 Balanced Flue Terminal |
A balanced flue is used on the Rayburn 480CD model.
There are a number of important points to be considered as to where the flue can be situated, so as to comply with current legislation and good practice.
Places to be avoided are ;-
Underneath windows // close to doorways // adjacent to obstructions or protruding buildings // discharging into car-ports and garages, alleyways or public thoroughfares // too close to a facing obstruction such as a fence.
As this is a condensing appliance, consideration should be given as to the possible nuisance caused by the natural pluming which will occur from the terminal.
The flue can only exit straight from the rear of the Rayburn to outside: bends are not permitted. Standard flue length 514mm
Optional extension up to 1000mm
No additional extensions are allowed, beyond these lengths.
The following illustration shows the minimum clearances required.
| A | BELOW A GUTTER OR SANITARY PIPEWORK | 600mm | H | VERTICAL FROM TERMINALS ON THE SAME WALL | 1500mm |
| B | HORIZONTAL FROM OPENING, AIR BRICK, WINDOW ETC | 600mm | I | HORIZONTAL FROM TERMINALS ON THE SAME WALL | 750mm |
| C | ABOVE GROUND OR BALCONY LEVEL | 300mm | J | BELOW AN OPENING, AIR BRICK, WINDOW ETC | 600mm |
| D | BELOW EAVES OR BALCONY | 600mm | K | FROM VERTICAL SANITARY PIPEWORK | 300mm |
| E | FROM AN INTERNAL OR EXTERNAL CORNER | 300mm | |||
| F | FROM A TERMINAL FACING A TERMINAL | 1200mm | |||
| G | FROM A SURFACE FACING A TERMINAL | 600mm |
These are minimum dimensions to ensure that the products of combustion can clear satisfactorily, but they cannot take into account any special adverse site conditions, such as extra turbulent wind in exposed regions. e.g. adjacent to cliffs or high hills.
If the flue terminates within 1 metre of plastic material such as guttering or waste pipes, they must be shielded for protection.
The protective wire cage must be fitted. (supplied with the Rayburn).
If the flue terminates on a wall which is clad with combustible material, this must be cut back 50mm beyond the outer edge of the terminal and replaced by a non-combustible material.
No air for combustion is taken from the room as the appliance flue-ways etc are room sealed, an alternative name for this type of appliance.
The ovens are vented naturally.
