Siting General; (A) Hearth Mounting; (B) Wall Mounting; (C) Fitting In A Fire Surround - Valor 474 Valentia Installation And Owner's Manual

In Northern Ireland, the current edition of the Building regulations (Northern
- Ireland) issued by the Department of the Environment for Northern Ireland.
In the Republic of Ireland the installation must be carried out by a competent
- person and also conform to the relevant parts of:
a) The current edition of IS 813 "Domestic Gas Installations"
b) All relevant national and local rules in force.
Where no specific instructions are given, reference should be made to the relevant
British Standard Code of Practice.

4.2 Siting General.

The fire must be mounted on the inner face of a suitable external wall of thickness
75mm minimum and 508mm maximum.
(a) HEARTH MOUNTING: If the fire is to be hearth mounted, the hearth must be of
non-combustible material at least 13mm thick and measuring at least 670mm wide by
300mm deep with the fire central. Its top surface should preferably be 50mm above
the floor level to discourage placing of rugs or carpets over it.
(b) WALL MOUNTING: The fire may be fitted on a non-combustible wall such that
the bottom of the backplate of the fire is at least 60mm above the finished floor level.
NOTE: Soft wall coverings e.g. blown vinyl wallpaper may become discoloured if
close to a heating appliance. Please bear this in mind when installing this fire and
when redecorating.
(c) FITTING IN A FIRE SURROUND (Fig. 1): The fire can be fitted in a compatible
fire surround having a standard gas fire cut-out or with a hole 135mm diameter to
accept the flue. The material of the surround must be suitable for 100 degC
application i.e. marked with the suffix '100'. The inside of the external wall should be
sealed off to prevent draught from the cavity into the room. A foam seal pack is
provided for this purpose. Wrap some of the foam seal around the inner air duct so
that when the fire is installed, the foam seal expands to prevent draught into the
room.
NOTES;
1. The foam seal starts to expand once the compression tape is removed. Hence
the foam seal should be put on only when the fire is ready to be installed.
2. When fixing the flue length, the wall thickness must be measured from the inner
face of the fire surround (Refer to Section 5.2).
