WESTFIRE ·WF35
Housing Construction, without an Existing Chimney Breast
If the property has no existing chimney or chimney breast the first consideration will be the positioning of the flue. Taking the flue to
the roof internally through the property will involve complying with many regulations and even an external flue may be subject to
planning regulations. Because there will be no existing structural hearth, this will need to be constructed following the strict Building
Regulation requirements. For these reasons we cannot recommend that anyone without the necessary experience constructs the
housing and flue system for a WF35 insert stove.
Insulating blocks
Lintel
Steel support
Insulation
Insulating board
Because the temperatures reached by the stove's top and side panels may reach over three hundred degrees Celsius all materials used
for constructing the housing must be both non-combustible, stable at high temperatures and insulate any part of the building which
may be affected by heat. It should be bourne in mind that insulating materials only limit the rate of heat transference from the heated
surface to the unheated surface and if the dispersal of heat from the unheated surface is less than the rate of heat transference the
entire body of insulating material will reach an almost uniform temperature.
