Preparation Of Wall - Valor 474 Valentia Installation And Owner's Manual

NOTE: The following instructions relate to normal brick walls. If the wall is wholly or
partly of combustible material, a combustible wall kit (optional extra) must be used.
Check the wall thickness. Three different sizes of flue available for wall thickness up
to 508mm as shown below. The medium flue is packed with the heater, the other
lengths must be ordered specially.

Place the template against the wall ensuring the top is level. For hearth mounting,
ensure that the centre of the flue is 351mm above the hearth. Mark the positions of
the flue and four fixing holes and remove the template.
Cut the hole for the flue making sure that it is straight and level. This can be done
with either a 135mm diameter core drill or hammer and chisel. If neatly drilled no
making good is necessary. If not it will be necessary to make good the hole especially
at the terminal end where the flue seal will be located and the inside wall face to
achieve a good seal.
Use the template to mark the fixing holes if necessary. Drill the four fixing holes to a
minimum depth of 57mm using 6mm diameter masonry drill and insert the plugs.
