1 Safety rules
- Read the supplementary hopper installation instructions carefully before carrying out any operation on the
accessory.
-
Have installation, the electrical connection, testing and maintenance of the hopper next to the pellet boiler done by
a qualified and/or authorised technician.
- In case of operation faults, the boiler with hopper can only be relit after eliminating the cause of the problem.
- Any tampering and/or unauthorised replacement with non-original parts of the hopper can create a risk for the
user's safety and relieves the manufacturer of any civil or penal liability.
- Make sure the unit is unplugged and cold before carrying out any work on it.
- Connect the boiler to an approved, easily accessed and adequately grounded 230 V - 50 Hz power outlet and
carry out the hopper - boiler connections in compliance with the current regulations and proper installation
technique.
- The hopper must only be used for holding loose wood pellets in conjunction with our boiler.
- Do not modify the safety or adjustment devices without the manufacturer's express permission.
- In case of fire, turn the boiler off, disconnect the power supply, use an approved fire extinguisher and request
immediate assistance from the Fire Department, avoiding continued attempts to extinguish it.
- Children must be supervised to make sure they do not play with the units.
- Arrange the power cable and any cables of external sensors so that they do not touch hot parts of the boiler.
- Only use original replacement parts recommended by the manufacturer.
The manufacturer declines any liability for problems, breakage or accidents caused by failure to follow or
apply the instructions contained in this manual.
2 Conditions of supply
The supplementary pellet hopper is complete with supporting structure, covering with a safety protection, pellet
auger, auger gearmotor and boiler LH or RH mounting connections-supports.
The accessory is supplied in a wooden crate, suitably protected by a nylon wrap.
The hopper complete with packing can be lifted using a lift truck, inserting the forks (of suitable length) in the special
spaces in the wooden pallet.
Hopper storage and transport must be carried out avoiding exposure to rain or persistent moisture which can cause
permanent damage to the structure and electrical-electronic components.
3 Technical data and conditions of use
The pellet hopper only works in conjunction with the boiler in LH or RH position.
Pellet loading occurs only from the compartment, which is uncovered by
opening the door
.
For the purpose of safety against accidental closing, there is a rod that blocks the
position of the door after opening, allowing safe loading of pellets in the hopper; to
close it, just operate on the rod groove and guide the door down to the stop.
During operation the door must remain completely closed .
Operation occurs by boiler commands at the time of the request, for a fixed time.
The supplementary hopper is fitted with a level sensor that controls the presence
pellets during operation and in case of no pellets displays the alarm via the boiler
control panel.
