Clearances around the Boiler
(Figs. 8 & 9)
1. The minimum clear spaces needed around
the boiler are:
Top
- 200mm
Bottom
- 130mm
Both sides - 5mm
Front
- 500mm
(For Servicing)
- 5mm
(In Operation)
2. The boiler may be installed in a cupboard if
these minimum clearances are kept and
permanent ventilation to the boiler is provided in
the compartment. The sizes of the ventilation
opening at high and low levels are as follows:
3.
These clearances and vents must not be
obstructed in any way. Blocking these will
result in the boiler overheating and possible
damage may occur.
4. The compartment should be large enough to
house the boiler and ancillary equipment only.
5.
IT SHOULD NOT BE USED AS A STORAGE
CUPBOARD.
6. 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.
7. The condensate drain must not be blocked or
modified.
