Montaje Del Quemador (Fig. 11); Conexión Tubo De Enfriamiento A La Mirilla; Assembling The Panels, Mod. Prextherm Rsw 720N÷1060N - Ferroli PREXTHERM RSW 92N Instruction For Use, Installation And Assembly

5.7 Montaje del quemador (Fig. 11)

The assembly of the burner at the boiler door must ensure perfect tightness for the products of
combustion. Once the burner is installed on the boiler, the space between the burner nozzle
and the refractory material on the door must be filled with the ceramic fiber padding (A) provi-
ded.
This prevents the door from overheating, which would result in irreversible warping.
The fuel connections to the burner must be placed so that the boiler door can open completely
with the burner installed.
It is advisable to place a rigid supporting base under the burner to prevent its full weight from
negatively affecting the door.

Connecting the cooling tube to the fl ame inspection window
The flame inspection window is equipped with a pressure fitting (1). Once the interior screw is
loosened, it must be connected to outlet 2 on the burner using a silicone hose or copper pipe.
This allows the air blown back by the fan to cool the glass on the window and prevent it from
turning black. Failure to connect the hose or pipe to the window can cause the glass to break.
When disassembling the window for cleaning, check the condition of the seals, replacing them
if necessary. After closing, verify tightness.
5.9 Assembling the panels, mod. PREXTHERM RSW 720N÷1060N

It is advisable to insert the pro-
bes fully into the sheaths to im-
prove contact. Then secure the
capillary tubes with the springs.
Close the cover on the electri-
cal panel and pass the burner
