Page 15: Fuel
3 FUEL General notes The pellet boiler is designed to burn wood pellets only. Wood pellets are a fuel obtained from the pressing of sawdust timber, extracted from the processing and transformation residues of dried wood material. The compactness of the product over time is guaranteed by a natural origin substance contained in the wood: lignin. -
Page 16: Assembly
Outlet connection in the rear of the boiler is illustrated in Fig. 15. Absorbed power is indicated in the product technical sheet, which can be downloaded from the website www.laminox.com. By law, the system must be properly grounded and with a differential circuit-breaker. Make sure that the electrical power cable does not come into contact with hot parts when set in its final position. -
Page 17: Water Connection
Water connection Connection of the boiler to the hydraulic system must be exclusively performed by qualified personnel, who is able to perfectly perform the installation, complying with the regulations in force in the Country of installation. If the installation of the boiler requires interaction with another pre-existing system equipped with another heating device (gas boiler, methane boiler, gasoline boiler, etc.), contacting qualified personnel able to respond to the conformity of the system, according to the requirements of the law in force regarding the subject, is more recommended. -

4.4.2 Indications for water treatment To prevent the heating system from having to be regularly cleaned it is best to install a magnetic sludge remover, this filter aids routine maintenance, increases boiler life span, aid removal of impurities and increased global efficiency of the system. The magnetic sludge remover filters the heating system removing sludge, ferrous or sandy residues which circulate in the pipes, if not removed they create surfaces which do not permit heat transmission, consequent pellet consumption and possible boiler malfunction... -
Page 19: External Thermostat Installation
4.5.1 Indicative hydraulic diagram External thermostat installation Boiler operation must be adjusted by an external room thermostat connected to the electronic board (see wiring diagram). The thermostat connection is performed with a 2x0.5 mm²cable. The contact to be used is NO (Normally open). This operation should be performed by qualified personnel. -
Page 20: Use
5 USE The Termoboiler line boilers are designed to operate 24/7 365 days a year. The boiler has been designed to maintain the water it contains above 70°C. This way, water will always be available for the domestic environment heat request or for the production of DHW. This does not involve continuous pellet consumption, as the boilers are adjusted automatically according to the heat requests of the connected utility. -
Page 21: Console Description
• CAUTION: if during cleaning, you find traces of spongy or hard (though not ash) pellets, replace the pellets being used as this residue may come from scraps of low-quality sawdust not usable in this type of boiler. Forcing ignition can cause a fire or strong production of fumes in the chimney. -

Page 23: Ignition And Normal Operation
When the tank is loaded for the first time, the feed screw must fill up for a given period. During this time, pellets will not be distributed within the combustion chamber. To overcome this difficulty, use the command "initial load" in menu 7 of the control panel (see further details below). Ignition and normal operation Before igniting the boiler: •... - Page 24 5.3.2 No start-up As said, if the onset of combustion is not detected, the no start-up alarm will be set off. The display will show the message "AL 5 NO START" and an acoustic signal will be heard at regular intervals (if the buzzer function is active in Menu 6).

to modulation, the fume temperature continues to increase and exceeds the second pre-set safety limit, the boiler will pass into alarm mode. Pellet flow is interrupted and fume exhaust speed is set to maximum. The display will show the message “AL 3 – SMOKE TEMP”. The boiler constantly controls smoke sensor functioning, If the sensor is momentarily and/or accidentally removed from its housing, or the connector is not correctly positioned on the circuit board or the sensor fails for any reason. - Page 32 To exit from an alarm condition, always press button "4" until the message "FINAL CLEANING" appears. You will also need to take additional steps, depending on the type of alarm generated If you do not exit from the alarm condition within a given time (a few hours), the alarm will be sent into boiler memory and the display will show the message "ALARM MEMORY".
