		4.1	Clearances around the Boiler
			(Figs. 20 & 21)
		1. The minimum clear spaces needed around the boiler
200mm	Min	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
	780mm
			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.
200mm		Min	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.
