4.1 Clearances around the Boiler
(Figs. 20 & 21)
1. The minimum clear spaces needed around the boiler
measured from the casing are as follows:
Top - 200mm
Bottom - 200mm
Left Side - 5mm
Right Side - 20mm/5mm
Front - 5mm (In Operation)
- 450mm (For Servicing)
* NOTE: The boiler can be operated with a clearance
of 5mm at the right. This is also sufficient for routine
maintenance. However a clearance of 20mm is
required if it is necessary to remove the secondary
heat exchanger. This should be considered when
siting the appliance and in the event of any subsequent
alteration in the area of installation.
2. These areas must not be obstructed in any way, and
must be maintained during the regular operation of the
boiler and for routine maintenance. Blocking the
clearance spaces may result in the boiler overheating
and damage may occur.
3. The gas burning compartment of your boiler is
completely sealed from the room in which it is fitted.
Products from the combustion of gas are vented to the
outside through the flue terminal which must be kept
free from obstruction as this would interfere with the
correct operation of the boiler.
4. The boiler may be installed in a cupboard if these
minimum clearances are kept. The compartment should
be large enough to house the boiler and ancillary
equipment only.
5. IT SHOULD NOT BE USED AS A STORAGE
CUPBOARD.
