Boiler Parts; Air Injection Collector; Air Distributor - Stropuva S7 Technical Passport, Installation And Maintenance Instruction

At the upper part of the chamber there's an air opening and air valve (1). On the right
side of the boiler, in front of the door, there is a lifting cord with ring (12) responsible for the
air supply mechanism and hook (13) for fixation of the cord.
With pellets, briquettes, damp firewood or other wood fuel and its residues we recommend to
use air injection collector. Air injection collector is mandatory when burning coal and peat. "U" and
"BIO" models come with air injection collector.
Air injection collector is plugged into electrical network after igniting and closing the boiler.

Air distributor's (3 Fig.) purpose is to correctly distribute air in generation zones, located below and next

distrubor so that there is a gap between telescopic pipe and air
distributor, (Fig. 5). When burning coal the additional ring has to be
removed to increase air supply towards the center. We recommend
attaching the air distributor without the gap between telescopic pipe
and air distributor when burning with coal (Fig. 6).
