Fireplace Clearances - Valor 474 Valentia Installation And Owner's Manual

4.3 Fireplace clearances (See Fig. 2).
4.3.1 The minimum height from the extreme top surface of the fire to the underside of
any shelf made from wood or other combustible materials is as follows:
For a shelf up to 150mm deep
Minimum height from the extreme top surface of the fire = 150mm.
For a shelf deeper than 150mm
150mm + 12.5mm for every 25mm depth over 150mm.
FIG. 2 Combustible shelf clearances.
There is no restriction on the depth of non-combustible projections but a space of at
least 30mm should be allowed above the top of the appliance to enable removal of
the fascia.
4.3.2.1 For combustible projections up to a depth of 178mm (Measured from the rear
fixing plane of the fire) a minimum clearance of 75mm should be maintained at the left
and right side of the fire. This is measured from the extreme side of the fascia. This
will allow easy access. This clearance is mandatory for temperature requirements.
4.3.2.2 For any combustible projections beyond 178mm (Measured from the rear
fixing plane of the fire) a minimum clearance of 100mm should be maintained at the
left and right side of the fire. This is measured from the extreme side of the fascia.
This clearance is mandatory for temperature requirements.
4.3.2.3 For non-combustible projections a minimum clearance of 75mm should be
maintained at the left and right side of the fire. This is measured from the extreme side
of the fascia. This will allow easy access.
If the fireplace opening is greater than the acceptable dimensions given in this guide,
do not use the back of a fire surround or marble to reduce the opening. This may
cause cracking of the surround back or marble.
