The boiler must be installed in a vertical position in accordance to the installation instructions.FLUE KITsTelescopic Flue‘B’ pack - contains: Flue turret, telescopic flue incorporating a terminal and rubber wall seals.horizontal Flue Terminal (600mm long) ‘B’ pack - contains: Flue turret, non telescopic single piece flue incorporating a terminaland rubber wall seals.horizontal Flue Terminal (1000mm long) ‘B’ pack - Flue turret, telescopic flue incorporating a terminal, rubber wall seals and instructions.Note. If ‘B’ packs are used on their own (either 1 piece or telescopic), then they can be fitted horizontally as the flue inside isdesigned to slope 1.5 degrees.‘D’ pack - contains: 1 metre length of flue pipe (Functional length 950mm), 1 support bracket and instructions.When extension ‘D’ Packs are used the flue duct must incline 1.5 degrees away from the appliance, to allow the condensate to drainback to the boiler and out of the condensate drain. It is recommended that a support bracket is fitted on every 1 metre of pipe workused and the bracket is located as close to the collar as possible. The bracketing must ensure a 1.5 degree fall back to the appliance.Optional Flue Finishing Kit - UIN 155988 & Concentric Flue Screw Retaining Kit (Optional Kit of mechanical fixing of flue joints)Only use water as a lubricant during assembly.The ‘B’ pack terminal is classed as part of the maximum flue length.These flue systems incorporates a removable flue outlet nose that utilises a push fit location system. This enables the installationof deflector, high level or balcony flue kits without the removal of the whole ‘B’ pack terminal. The appliance must not be operatedwithout the desired outlet nose correctly fitted in place, ensuring the side location dimples are in line with the mounting faceallowing the correct sealing of the components.It is IMPORTANT that all attachments are fitted in accordance to the installation instructions provided with them.The TURRET supplied in the ‘B’ Pack has an upper combustion sample point with a screw cap seal and a lower air sample pointwith an air stopper seal. Ensure all caps & seals are in place.additional Termination Kits available for use with these ‘B’ packs.Flue Deflector Kit The resistance is the equivalent of 1 metre of flue pipe and therefore must be deducted fromany maximum flue lengthHigh Level Flue Outlet Kit The maximum permissible concentric flue length when using a standard (500mm) kit is 4.5 metresBalcony Flue Outlet Kit The maximum permissible concentric flue length when using this kit is dependant on the lengthof the balcony flue outlet run which combined with the concentric run must not exceed themaximum flue length requirement of the appliance it is to be fitted toTotal Maximum permissible horizontal Concentric Flue Length combining both ‘B’ Packs and ‘D’ Packs(Measured from centreline of the turret to the outside of the wall terminal)15, 18 & 24 kW appliances Total Maximum: 9 metres - minus any flue kit options or bends30 kW Appliances Total Maximum: 8 metres - minus any flue kit options or bendsTotal Maximum permissible Vertical Flue Length combining both Roof Terminal and ‘D’ Packs15, 18, 24 & 30kW Appliances Total Maximum: 7.5 Metres - minus any bendspowered Vertical Flue15, 18, 24 & 30kW Appliances Total Maximum: 5 Metres - Concentric Flue and 17m flue pipe only.
