DT2010230-03 1.8 INTERIOR vENT INSTALLATION This kind of installation provides the natural draft that results from Fig. 10 a vertical rise avoiding smoke being released into the house when RAIN CAP electricity to the unit is interrupted while burning or smoldering pellets remains in the burn grate.
DT2010232-02 1.9 CONNECTING TO A CONvENTIONAL ChIMNEy The stove may be connected to an existing Class A chimney or a masonry Fig. 12 chimney which meets the minimum requirements of NFPA 211. Using this kind of installation the pellet stove is able to draft naturally without exhaust blower operation (failure), reducing the probability of burn-back and back-drafting.
DT2010232-02 1.10 INSTALLING INTO AN ExISTING FIREbOx ChIMNEy This kind of installation also provides natural draft in the event of a Fig. 15 power failure. When installing as a hearth mount stove into a firebox the unit must either be relined, terminating above the chimney chase top, or positively connected to the existing chimney system using a block off plate (Fig.
This configuration will help prevent blockage of vent by snow drifts. Also the minimum vertical run of 5 feet (1,5 m) ensures the ventilation of the exhaust in the event of a power failure, and allow for easier cleaning through cleanout on tee. Certain local code restrictions may apply.
The clearance to a door, window or cavity must be at least: - 1.5’ (458 mm) below; - 1.5’ (458 mm) horizontally; - 9’’ (230 mm) above. The clearance to fresh air intake for combustion of the pellet stove or any other appliance, or the non-mechanical air supply inlet to the building must be at least 4’...

DT2010994-00 6.19 SAFETy dEvICES During operation some parts of the stove (door, handle, ceramic parts) can reach high temperatures. Remember to maintain the safety distances indicated previously. Be careful, take all due precautions and always comply with the instructions. If during operation smoke leaks from any part of the stove or the flue, shut the stove down immediately and ventilate the room. When the stove has cooled, check for the cause of the leak and if necessary call in specialist personnel.

PELLET HOPPER HOUSING TEMPERATURE Sensor Description Display Located on the pellet hopper, its function is to prevent excessive temperature ranges. WHEN ACTIVATED T A N K T E M P If the pellet hopper temperature reaches critical levels, the thermostat cuts off the power supply to the fuel-loading auger, thereby stopping the S A F E T Y supply of pellets to the grate and starting the stove shutdown process.
STOVE ROOM TEMPERATURE SENSOR Sensor Description Display Connected to the rear of the stove, it constantly monitors the temperature in the immediate vicinity of the stove to ensure that it can be operated in all safety. WHEN ACTIVATED L E V E L If the sensor is momentarily or accidentally removed from its normal position, the problem does not require the immediate shutdown of the Room sensor...
DT2010337-03 6.21 hUMIdIFIER The stove comes equipped as standard with a humidifier placed Fig. 63 underneath the food warmer. Once the stove’s ceramic cover has been fitted, the humidifier can be filled with water using the spray bottle, by inserting the neck of the bottle into the hole provided.
7.0 MAINTENANCE DT2010157-00 Pursuant to current regulations on the safety of electrical equipment, you must contact your dealer or a qualified electrician for all and any work connected with installation, maintenance or servicing that involves access to electrical parts or internal mechanical parts. Maintenance is to be considered compulsory for correct and efficient stove operation.
DT2010158-01 7.3 CLEANING ThE COMbUSTION ChAMbER Once a week clean the firebox as follows: Fig. 66 - remove the grate and the ash tray; Upper rear - loosen but do not remove the two hexagon-head brass screws M6 baffle located on the sides in the top part of the two lateral baffles; - with one hand lift the “Upper rear baffle”;...
DT2010092-03 7.5 CLEANING ThE FLUE SySTEM Soot and Flyash: formation and need for removal. Fig. 71 The products of combustion will contain small particles of flyash. The flyash will collect in the exhaust venting system and restrict the flow of the flue gases.
Any build-up of dust or ash on the blades can unbalance them resulting in noise during operation. It is necessary to have the fans cleaned annually. Since such an operation involves dismantling certain parts of the stove, have the cleaning carried out only by a Piazzetta Service Centre or other qualified persons.
DT2010096-04 7.12 whEN NOT IN USE When shutting the stove down for the summer, proceed as follows: - remove all pellets from the hopper and feeding auger; - carefully clean the grate, the grate support and the ash drawer; - using a steel brush, clean the baffle plate or internal baffle plates of the firebox and coat them using the spray paint, supplied with the kit, to prevent them from oxidising and consequently forming rust.
8.0 TROUbLEShOOTING DT2011179-01 Some of the problems indicated below may be resolved by following the instructions. All work must be carried out when the appliance is cold and disconnected from the electricity supply (pull out the plug). Authorised qualified persons must be contacted, in accordance with current regulations, whenever it is necessary to work on parts inside the cladding or the firebox in order to resolve the problem.
