Nu-Flame Vitesse H.E. Use, Installation & Servicing Instructions page 16

k. The Surround must cater for a minimum flat surface around the Fireplace Opening allowing 610mm high by 510mm wide.
This is essential in order to achieve a good seal between the face of the surround and the sealing flanges of the fire.
l. The Fire Surround must be fully sealed to the Fireplace Opening to ensure a good flue seal.
m. For a Hole in the Wall Installations It is essential to use marble, slate or stone slips, fitted around the builders opening.
The slips must have a temperature rating of 150
n. In order to direct the flow of heated air away from the wall we recommend that a non combustible shelf (lip) is fitted above the
top slip, protruding 30mm – see diagram.
o. There must be a flat surface around the opening of sufficient area to enable the slips to be securely fitted. The slips should be
fitted to the wall in such a way that they form a seal to stop air from the room being drawn behind the slips into the False
Chimney Breast. We recommend a high temperature silicon sealant.
p. The recommended height for the base of the Builders Opening is 350mm above floor level. The minimum height for the base of
the Builders Opening is 250mm above floor level.
q. The Fireplace Opening should have provision for a gas supply through the rear, see Section 10 Gas Supply.
r. The Thermatronic fire is fitted with Electronic Equipment, which is sensitive to dampness and high humidity so it is very
important that any rendering/building work is allowed to thoroughly dry out before Installation.
! IMPORTANT NOTE !
13.3 - CLEARANCES TO COMBUSTIBLE MATERIALS AND SHELVES (Ref: Diagram Above)
The Requirement for Shelves for Hole in the Wall Installations is Detailed in the Above Section.
a. For Fire Surrounds a non combustible shelf can be fitted above the fire and should be positioned at least 95mm above the
builders opening. We recommend the depth of the shelf should be a maximum of 75mm as anything deeper will reduce
convection air and the efficiency of the fire. For deeper non-combustible shelves they must be raised a further 25mm for every
extra 25mm of depth.
b. For Fire Surrounds a 150mm combustible shelf can be fitted above the fire but must be positioned at least 195mm above the
builders opening. For deeper combustible shelves they must be raised a further 25mm for every extra 25mm of depth.
c. Any combustible sidewall must be at least 500mm from the inside of the builders/fireplace opening, however with a combustible
fire surround it can be 275mm from the inside of the builders/fireplace opening provided it does not protrude more than 150mm
and this must be increased by 25mm for every extra 25mm of depth.
d. With all heating appliances, soft furnishings, decorations and wall coverings may discolour or scorch if placed too close.
e. No combustible material, e.g. curtains must be closer than 500mm to the builders opening.
f. Any combustible wall claddings (wall paper) must be cut back to a height of 750mm and 300 mm either side of the Fireplace
Opening.
g. Due to the heat output of The Vitesse H.E. it is not recommended to use blown vinyl wall covering around the fire.
NOW PROCEED TO SECTION 15 - FIXING THE FIRE.
º
C and be 20mm (min) thick by 100mm (min) wide.
Do not forget to take account of the difference in height of the base of the Flue Box when
mounting the box on the floor; it must be level with the Hearth.
