PREXTHERM RSW N
The boilers are fitted with a door featuring hinges that can be reversed for opening to the right or left, and is adjustable in both height and
depth. The body is insulated with a thick layer of glass wool, and covered with a further layer of tearproof material. The external finish con-
sists of painted steel panels.
The boilers feature two 1/2" fittings for bulb sheaths (able to house 3 bulbs each). The pre-wired control panel is located above the boiler,
and allows for automatic operation.

4.2 Operating principle

PREXTHERM RSW N boilers are fitted with a closed cylindrical furnace, in which the flame produced by the burner is reversed peripherally
toward the front. From there, the burned gas enters the fire tubes. At the outlet, the gas is collected in the smokebox, and is then sent to the
chimney. The combustion chamber is always pressurized during burner operation. For the pressure values, see Table 1, in the column Flue
gas side pressure drop. The flue and flue stack fitting must be made in accordance with current standards and legislation, using rigid pipes
that are resistant to high temperatures, condensate, and mechanical stress, and are airtight.
