designed to slope 1.5 degrees.
‘D’ pack
When extension ‘D’ Packs are used the ue duct must incline 1.5 degrees away from the appliance, to allow the condensate to drain
back to the boiler and out of the condensate drain. It is recommended that a support bracket is tted on every 1 metre of pipe work
used 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.
