12.0 conventional
flue installation
The Strata 1 boiler has an excess pressure combustion system, which coupled with the very low flue
gas temperatures produced allows the appliance to exhausted over considerable distances using 80mm
Polypropylene PPS flue pipe and fittings. Suitable flue pipe and fittings are available from MHS Boilers Ltd
and are listed below.
The flue should be installed to have at least a 3° fall to the boiler to allow any condense formed in the
flue to run back to the boiler.
The flue system used must be gas and water tight and must be adequately supported over it’s entire
length. Support at 1 metre intervals. It is not necessary to install a terminal to the flue system, however, a
mesh guard should be included to prevent blockage or entry of foreign material. Straight lengths may be
cut to size with any surplus cut from the plain end. Tube ends should be cut square and de-burred.
Care should be taken when selecting a position for a low level discharge or discharge adjacent to
windows etc as the flue terminal will plume heavily and the white water vapour discharge may cause a
visual nuisance.
