Disassembly of combustion circuit main components.
Before disassembling the components, make sure the gas cock
is closed.
Gas nozzle replacement (17).
Loosen the gas pipe (14) in order to access the gas nozzle (17)
positioned at the entry of the Venturi pipe, then replace it with
the gas nozzle that has the suitable diameter for the type of gas
(see gas transformation).
N.B.:
on re-assembly of the nozzle (17), pay particular atten-
tion to the correct positioning of the gas gasket.
Burner disassembly (8).
Loosen the gas pipe (14) and unscrew the two screws (19) that
fix the manifold to the fan, and then loosen the 4 blind nuts
(12) that block the gas manifold flange to the condensation
module (7). To replace the burner graphite gasket (9) loosen
the 4 screws (22).
N.B.:
on re-mounting the burner/manifold unit, pay particular
attention to the correct positioning of the cord packing (21),
gas gasket (23), gas pipe gasket (14) and gasket between fan
flange and gas manifold (11).
Disassembly of the condensation module (8) including
flue hood.
Before carrying out the operation drain off all water present
inside the module.
Disconnect the system flow and return pipes and the con-
densate discharge pipe positioned in the lower left part of the
module itself.
Push the stub pipe (1) down in a way to release the module
including the flue hood from the flange with sample points.
Loosen the four screws (6) that fix the condensation module (7)
to the support sheet steel (4), which are fixed using the screws
(5) to the rear support frame and then extract the module
frontally making it run on the slides made in the sheet steel
(4).
N.B.:
when restoring the connection between the module
including flue hood and flange with sample points, check
the status of the two flue gaskets (2) and (3) and their correct
positioning.
When restoring the connection between the flow and return
pipes and the module, check the status of the O-rings (24) and
the correct positioning of the blocking clips (25).
Disassembly and replacement of ignition and detection
electrodes.
Loosen the two fixing screws on the ignition electrodes unit
(20). Loosen the two fixing screws on the detection electrode
(13).
N.B.:
when re-mounting the detection electrodes (20) be sure
to remount the gasket correctly. For the detection electrode
(13) be sure to re-mount the OR gasket. For both electrodes
scrupulously follow the minimum heights stated in the drawing
in the page at the side.
