· The flue pipe assembly is made of steel pipes S 235 J RG 2 UNI EN 10.027/1, 4 mm thick. ;
· Fully adjustable doors that allow perfect sealing of combustion products;
· Total casing made of steel sheet painted with epoxy powder and insulated with mineral wool 80 mm thick, in order to reduce heat dispersion due to passive loss;
· This Arca PRK series steel boiler has a 1-stage electronic burner panel, equipped with: operating thermostat, safety thermostat with manual reset, thermometer, minimum thermostat, anti-inertia thermostat, general switch, circulation pump switch, burner switch.
· The panel housing is made of plastic material with a minimum degree of protection IP 40.
Smoke Path:
· The combustion chamber with a reverse flame and the effect of irradiation of the refractory material of the entrance door enable an extremely high degree of comminution of combustion particles.
Fully adjustable doors:
· Fully adjustable doors are lined with fireproof material; it is necessary that the door ensures a perfect gas seal, because the combustion chamber is under low pressure; so any small hole will produce high temperature gas leakage. For these reasons, the structure of the central door of the MK model has been specially studied to allow all possible adjustments: it can be raised, lowered and tilted and, to replace the support, it can be opened from the right or left.
