For those wishing to further reduce the noise from their Heatsource heater then this kit will enable both the internal blown air and the combustion noise to be reduced. The kit includes:
1 Metre acoustic ducting
1 x Exhaust silencer
1 x combustion inlet silencer
additional 22m exhaust length
hose connectors and fittings.
To get maximum effect for the blown air side it is recommended to fit a minimum of 0.75 metre of acoustic ducting to the outlet and 0.25 Metre acoustic ducting to the inlet.
For the exhaust; the existing 22mm pipe should be removed from the heater, the new silencer and supplied pipe fitted directly to the heater and the original pipe fitted to the new silencer.
For the inlet silencer; the end cap needs to be removed from the existing black pipe and the new silencer screwed in.
