Housing Construc�on, without an Exis�ng Chimney Breast

If the property has no exis�ng chimney or chimney breast the first considera�on will be the posi�oning of the flue. Taking the flue to
the roof internally through the property will involve complying with many regula�ons and even an external flue may be subject to
planning regula�ons. Because there will be no exis�ng structural hearth, this will need to be constructed following the strict Building
Regula�on requirements. For these reasons we cannot recommend that anyone without the necessary experience constructs the
housing and flue system for a Christon insert stove.

Because the temperatures reached by the stove’s top and side panels may reach over three hundred degrees Celsius all materials used
for construc�ng the housing must be both non-combus�ble, stable at high temperatures and insulate any part of the building which
may be affected by heat. It should be bourne in mind that insula�ng 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
en�re body of insula�ng material will reach an almost uniform temperature.
