DIRECTION H MIN 5' OF CLEANING PELLET STOVE Gruppo Piazzetta S.p.A. assumes no responsibility for, nor DIRECTION does the warranty cover, smoke damage caused by reverse OF CLEANING drafting of pellet stoves under power failure conditions or as a result of extreme negative pressure in the home.
1.8 INTERIOR VENT INSTALLATION DT2010230-03 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.
1.9 CONNECTING TO A CONVENTIONAL CHIMNEY DT2010232-02 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.
1.10 INSTALLING INTO AN EXISTING FIREPLACE CHIMNEY DT2010232-02 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.
1.13 VENTING: TERMINATION REQUIREMENTS DT2012157-00 In determining optimum vent termination, carefully evaluate external conditions especially when venting directly through a wall. Since you must deal with odors, gases, and fly ash, consider aesthetics, prevailing winds, distances from air inlets and combustibles, location of adjacent Fig.
• The exhaust termination location (Fig. 21) must be at least: Fig. 21 - 1’ (305 mm) above the ground level. Attention : the minimum vertical rise shall always be not less than 5’ (1.5 m). A flue at 1’ above ground is not enfant safe: we strongly reccomend that the exhaust termination of flue be raised another 4’...
1.15 MOBILE HOME INSTALLATION DT2010027-02 The stove has been tested and listed for mobile home installations.

6.12 MULTICOMFORT DT2010251-03 The pellet stove is fitted with the Multicomfort function. This works in conjunction with the Multifuoco ventilation system to improve heat distribution. It allows the room temperature to be read from the stove or from the remote control, so that the Multifuoco settings can be varied according to the requirements of the rooms to be heated.
Page 46
When the room temperature measured by the room sensor or the remote control drops to the temperature value set by the user on the START function (e.g. -6 °F / -3 °C compared to the programmed temperature), the stove starts a new ignition phase and goes back to the power level previously set by the user.

6.19 SAFETY DEVICES DT2010994-00 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.

FUEL HOPPER LID SENSOR Description of activity Display Connected to the fuel hopper lid, its function is to disable the fuel feed auger motor when the hopper lid is open as required by UL and ULC standards. WHEN ACTIVATED: C L O S E If the sliding top panel remains open, the lid switch cuts off the power supply to the fuel-loading auger, thereby stopping the supply of pellets to the grate.
Page 55
FLUE GAS FAN RUNNING Sensor Description Display Its function is to check correct operation of the flue gas fan so that the stove can be used in all safety. If the black-red-white cable connected to the flue gas fan (see the S M O K E F A N paragraph “WIRING DIAGRAM”) momentarily or accidentally removed F A I L U R E...
Page 56
FLUE GAS TEMPERATURE SENSOR Sensor Description Display Connected to the electronic board, it constantly monitors the working temperature allowing the stove to be used in all safety. WHEN ACTIVATED If the temperature exceeds the fixed safety limit the board cuts off the power supply to the fuelloading auger thus depriving the grate of pellets S A F E T Y and starting the stove shutdown process.
6.20 OPENING THE DOOR DT2010087-04 During operation the door must remain closed. Fig. 59 It is to be opened only when the stove has been shut down and cooled in order to carry out maintenance operations. Since the fire box door handle can reach hot temperature, the appliance is fitted with a detachable handle on the rear panel of the stove as shown in the figure.
7.0 MAINTENANCE DT2010249-01 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.
7.3 CLEANING THE FIREBOX DT2010428-03 Once a week clean the firebox as follows. Fig. 65 - Remove the grate baffle and draw out the grate. ECCENTRIC CLAMP - Turn the eccentric clamps to free the internal baffle. INTERNAL BAFFLE - Lift the baffle slightly, gripping it by the two outer tabs to free it at the bottom and then turn it, bringing the bottom outwards, and remove.
7.5 CLEANING THE FLUE SYSTEM DT2010092-03 Soot and Flyash: formation and need for removal. Fig. 69 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.
Do not slam the door or hit the window. In case of breakage replace only with a Gruppo Piazzetta spare part. Replacement of the glass should be done by a qualified service technician. To replace, proceed as follows: - wear protective gloves;...
It is necessary to have the fans cleaned at least once a year. Since such a procedure involves dismantling certain parts of the stove, have the cleaning carried out only by a Piazzetta Service Centre or other qualified persons. To access the room fan/s, remove the side ceramic panel/s (see instructions in CLADDING booklet).
7.12 WHEN NOT IN USE DT2010096-04 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 a spray paint (not supplied), 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.
