The MI Flues Storm Collar is for use with a 5" Twinwall Flue (125mm). It comes in a choice of stainless steel or matt black finish.
A rebate is the measurement between the back of the wall to the front of the back panel. To allow you to calculate the recess needed you must subtract the rebate by the thickness of the back panel.
100mm (rebate) – 20mm (back panel depth) = 80mm (fire recess depth)
Please note if a fire surround is fitted to a chimney then the depth of the fire/stove will be recessed within the chimney cavity, if the surround is fitted to a flat wall the full fire depth will need to be recessed within the surround.
