REMOVING THE SMOKE BAFFLE PLATES
The appliance is fitted with two smoke bafle plates, which are
designed to lengthen the path of the flue gas or smoke by increasing
the heat exchange surface area. The smoke baffle plates rest on
supports inside the fireboxes, as shown in figure 41-42.
Should it be necessary to replace the smoke baffle plates, unscrew
the hexagon nut (for the fireboxes 650HT and 655HT only) to be
found on the left part of the smoke baffle plates, push the smoke
baffle plates upwards, turn them downwards and remove them.

CLEANING THE FAN (ONCE A YEAR)
All cleaning and maintenance operations must be carried out after DISCONNECTION OF THE POWER.
Pursuant to current regulations on the safety of electrical equipment, you must contact a Piazzetta After-Sales Service Centre or a
qualified electrician for all and any work connected with installation, maintenance or servicing that involves access to electrical parts.
Dust can accumulate in the ventilation kit and in particular in the holes of the protective cover of the fan, the grilles and the fan blade, which
should therefore be cleaned once a year. Use a vacuum cleaner or compressed air, being careful with the electrical parts.
The ventilation kit must be disassembled for proper cleaning. Follow the installation procedure in the reverse order (see the instructions
enclosed in the kit).

SHUTTING DOWN
Before any long period during which the firebox will be inactive we recommend that you carry out a thorough cleaning, thereby avoiding
encrustations and oxidations which will be difficult to clean later. We also recommend that as a preventative measure you carry out a general
checkup as outlined in the paragraph headed “
PERIODIC CHECKS
”.
After a period of inactivity problems relating to the expansion of parts or the release of odorous gases may arise. We therefore recommend
that upon restarting the unit you do not immediately run it at full power. Nor should you activate the ventilation system until the odorous gases
have dispersed. This problem can be dealt with by simply airing the room.

CLOSING DOOR SYSTEM
This operation should be carried out by specialised personnel.
The “rise n’fall” door closing system must be checked periodically, at least once every two years; attention must be paid in particular to
lubricating the roller located inside the double glazing or, depending on the model, the pulleys located outside the double glazing.
