About this deal

The Ventilated Ceiling Support kit is a support assembly consisting of two Ventilated Ceiling Support plates and a Support Band. The Ventilated Ceiling Support plates are screwed to the ceiling and to the joists above, through which the flue goes through. The Support Band is then tightened around the pipe resting on the upper plate, carrying the weight of the flue system. Clearline Stainless steel single skin flue can be cut to length, cutting from the female end of the pipe. If you need to use a joint clip on the cut end gently bend it out with pliers in four places to give the joint clip something to grip.

The Firestop Cover Plate fits to the Ventilated Ceiling Support and covers up the hole around the double skin flue. Home> Help & Advice> Installation & Regs> Chimney Installation>Twin wall flue systems Twin wall flue systems When cutting enamel flue pipe with an angle grinder wrap the section you are keeping in a cloth to protect the enamel. Be careful that you cannot catch the cloth in the angle grinder. You cut the plain female end but you will lose the swage which normally sits on the flue collar. Double skin flue cannot be cut to length, but adjustable lengths are available. Spraying stainless steel flue pipe On first lighting your stove only light a small wood fire for about 1hr and then let it die out. Once the stove has cooled you can burn as normal. On the first few firings you can expect some smoke/odours to come off the stove and a slight acrid odour. This is completely normal and is part or the curing of the fire cement and stove paint.Where single skin flue pipe is used from the stove which then changes to twin wall below the ceiling, the changeover point should be at least 425mm below the ceiling. A Storm Collar is clamped around the pipe, with a bead of silicone mastic, just above the flashing plate. A storm collar can also be used on the angled arm of a 135* T where the flue has passed through an outside wall. Adjustable Wall Bands are used to fix the flue to a wall where the flue is further away than a wall band would allow for. Adjustable Wall Bands come in three sizes, 80-130mm, 130-210mm and 210-420mm. These components are not load bearing.

The flue must be at least 50mm from combustible surfaces, so any holes in combustible floors etc must be cut 120mm larger in diameter than the external diameter of the flue. Thus you should cut a 320mm diameter hole for 150mm double skin flue. Single skin flue pipe should be at least 3 times its diameter away from combustible materials (ie 150mm pipe should be 450mm from combustible materials). Building Regs do not specify clearances for the stove itself and manufacturers recommendations vary greatly. As a general rule maintain at least 100mm from non-combustible surfaces and at least 400mm from combustible surfaces. You can effectively heat shield materials by using 12mm fireboard with a 12mm air gap behind. Cutting single skin flue Make sure that the flue is free from dirt & grease and spray it once it is installed. The paint undergoes its final curing once the flue heats up.
