For connection of thermal ducting with inner duct connectors we
recommend the use of Galva Mate, solvent free low odour sealant.
Sealant should be applied in the middle of the connection face with a
minimum bead width of 5mm.
Fit ducting over connector ensuring end face butts up to connector
shoulder. Allow minimum of 1 hour curing time at room temperature.
