Burley G4237/8 warranty Method Two - Inset On Hearth Or Inset Wall Mounted

5.3METHOD TWO - INSET ON HEARTH OR INSET WALL MOUNTED

This method allows for the fire to be inset into a wall or fireplace opening. The appliance case has a 90mm deep spacer that needs to be removed and the corresponding deep brackets need to be taken off the case. Note these are the only spacer and brackets to be removed and the smaller bracket and spacer must be left in place. The appliance gets very hot and could cause burns therefore if wall mounting without a hearth then care should be taken to avoid gangways and congested areas. Care should also be taken with curtains and soft furnishings to ensure there is no possibility of them touching the appliance.

							Hearths - For hearth mounting (or if the
		338mm					fire is less than 200mm above the
							ground) then the hearth must protrude
			DIMENSIONS				at least 100mm in front of the fire and
			REFER				50mm to either side. A minimum hearth
			PORTION
							of 732mm wide x 207mm deep is
	632mm				107mm		required, the hearth must be a minimum
							of 12mm thick and be of a non
							combustible material. The surface on
							which the appliance is to stand must be
							flat, level and square to the back panel.
590mm
				486mm
							Failure to observe this could result in the
							appliance leaning away from the
						91mm	fireplace.
							If the appliance is fitted on the wall,
more than 200mm above the ground then a hearth is not required.

The hearth and back panel must be made from a non-combustible material although ‘lightweight’ and tiled surrounds can be used provided they have a minimum heat rating of 150oc. Consideration should be given to the effect of expansion and contraction caused by temperature and back panels should be allowed to float or attached with a flexible mastic on the extreme edges.

Fireplace opening sizes –	Height – 500 minimum	570 maximum
	Width – 350 minimum	465 maximum

The fireplace opening must be a minimum of 100mm deep

Ensure adequate clearance from the fire to allow it to expand in the fireplace opening or it may crack the marble back panel.

To prevent heat from entering the area between the fireplace back panel and wall, the void must be blocked or packed with a non-flammable material.

Chimneys & under grate draught devices – To prevent draught from affecting the stability of the appliance flames, all undergrate draught devices within 1 metre of the fire must be blocked off.

If fitting into an existing fireplace or flue, the flue and cavity MUST be blocked off completely and cavity wall box CAV4241 fitted, to prevent suction on the back of the appliance (fit in accordance with the instructions supplied with the cavity box). The top of the flue should also be capped off to prevent the entry of moisture etc, consult building control if in any doubt.

If fitting into an opening in a cavity wall, or into a void, use cavity wall box (part no. CAV4241 ) and fit in accordance with the instructions supplied. Failure to do so can result in the pull from the cavity causing heat build up on the fire surround, back panel or moisture ingress from the cavity.
