1.2.13. soundproofing
The Power Unit comes with high-grade airborne and solid-borne soundproofing. (<49 [±2] dB (A), at 1 m distance with hood
closed); but noise-sensitive areas should be taken into account when deciding where to install it. To avoid solid-borne noise
carrying into building structures, all connections between the XRGI and building systems must be made via flexible connections
(hoses) or suitable soundproofing expansion joints. When installing the flue gas pipe, only clips with sound-insulating lining must
be used (class T160). Under no circumstances may the flue gas pipe come directly into contact with building structures. Com-
bustion engine flue gases pulse in time with engine combustion cycles and stress the flue gas pipe accordingly: they cannot be
compared with the even flue gas flow from boilers.
Although the Power Unit is well insulated against airborne and solid-borne noise, additional measures may be required in noise-
sensitive areas close to the Power Unit.
One tried and tested solution to solid-borne noise is to set the Power Unit on a reinforced concrete plinth (dimensions L x W x H
= 1400 x 800 x 200 mm, weight approx. 500 kg), which itself fully rests on Sylomer insulation, such as Puroplan 1.5/50 yellow
(two-layer), made by Moschner & Partner.
Alternatively, noise-reducing feet are available which reduce solid-borne noise transmission to the building itself.
The base tray has an integrated flue gas silencer to reduce flue gas noise. This is sufficient in many cases. If flue gas noise has
to be reduced to a minimum, an extra flue gas silencer is available, which is installed behind the XRGI.
Consult a building engineer if necessary.
