The 45 degree elbow plain is the ideal bend to create an offset or change of direction in a flue system such as prior to passing through a wall and converting to twin wall insulated pipe. These parts receive a coating of enamel to match the traditional aesthetic of a wood burning or multi-fuel stove and to guarantee the resistance of the finish even at very high temperatures. Connection: vitreous enamelled flue parts have a male connection to push fit inside the pipe or stove outlet below to ensure deposits within the pipes run down into the stove and do not escape. The male connection is always fitted facing downwards as pictured. It is advisable to seal all single wall joints with a suitable high temperature sealant. It is safe to cut single wall flue down to size for a perfect fit. Construction: easy fit vitreous enamelled flue is constructed from 1.2mm thick laser welded steel. These pipes are not insulated. Approvals: fully CE approved for installation in compliance with UK building regulations. Regulations: designed for internal use, it is against regulations to pass single wall flue through any surfaces due to the heat emitted from the pipe. The safe clearance to combustibles is three times the diameter of the flue or one and a half times the diameter to non-combustibles. It is advised to limit a run of single wall flue to 2000mm to prevent the loss of heat through the pipe which can lead to flue gases dropping.
