1.3. Exhaust equipment effects:
If no sufficient ventilation is ensured, exhaust equipment in the
same air space with the fireplace (including rooms behind a door
provided with a ventilation grille or rooms with doors open) may
disturb fireplace operation. Therefore exhaust devices must be
provided with the air supply indispensable for their operation.
Important: if, for instance, outward air flow is only ensured for your
vapour extraction device, it will not operate efficiently because it
cannot take in air from anywhere. E.g. an exhaust device with a
capacity of 600 cubic metres of air / hour will carry only 200 cubic
metres of air. This reduces air pressure in your living space which is less
than favourable to our general state of health. In certain cases, return
flow can occur in case of not completely closed fireboxes (smoke gets
into the living space) when out of service or when the door is opened.
In case of inadequate ventilation, the firebox glass is also increasingly
sooted.
1.4. Operation of a water jacket firebox
A firebox with a water jacket is only allowed to be operated if
connected to a water system filled up with water, designed and
installed by a heating engineer. The specialist makes sure to integrate
the firebox into the system appropriately, connected to each of the 1-
inch forward and return stubs diagonally, by plugging any unused stubs
in order to prevent overcooling for adequate efficiency. The two half-
inch stubs with external threading are the connection points for the
cooling circuit (coilpipe) to prevent water from boiling and steam
generation; they should not be plugged in case of an open system. It is
recommended to fill the firebox with soft deionized water.
