The pipe between the boiler and the flue must be made from material suitable for this purpose, that is, resistant to both high temperatures and corrosion. The joints should be carefully sealed and the entire length of the pipe between the boiler and the flue should be thermally insulated, to avoid the formation of condensate. - Page 6 PREXTHERM N Fasten the 2 front “side support brackets” Place the sides on the boiler shell. “1” Secure the sides at the front and rear.
