INTRODUCTION
Important safety instructions
Please read these instructions before installing and using the product.
-The installation and initial start-up of the appliance must be performed by skilled personnel trained in the relevant

KLOVER srl shall not be held liable if these precautions are not observed.
-During the installation and use of the appliance, all local regulations - including those referring to national and
European Standards - must be observed.
-Connect the flue gas outlet to a flue with the specifications described in the “Flue and its connection” section of this
User guide.
-The appliance is not suitable for installation on a shared flue system.
-If the flue should catch fire, use appropriate fire extinguishing equipment or call the fire brigade.
-Connect the product to an earthed power socket. Avoid using sockets controlled by switches or automatic timers.
-Do not use the power supply cable if damaged or worn.
-If a multiple socket is used, make sure that the total voltage of the connected devices does not exceed the rated
voltage for the socket. Also make sure that the total voltage of all the devices connected to the socket does not
exceed the maximum permitted level.
-The plug on the appliance’s power cable should be connected only once the assembly and installation of the
appliance is complete. It should remain accessible after installation if the appliance is not fitted with a suitable and
accessible two-pole switch.
-Do not use flammable substances to clean the appliance or its parts.
-Do not leave flammable containers and substances in the place where the appliance is installed.
-The appliance works exclusively with wood pellets and only with the hearth door shut.
-NEVER open the door of the appliance during normal operation.
-The use of poor quality pellets or any other material can damage the appliance operation, voiding the warranty and
exempting the manufacturer from all liability.
-Do not use the appliance as an incinerator or for any use other than that for which it was designed.
-Do not use fuels other than those recommended.
-Do not use liquid fuels.
-The appliance, and its outer surfaces in particular, become very hot to the touch during operation; handle with
caution in order to avoid burns.
-Keep fuel and flammable materials at a safe distance.
-Only use original spare parts recommended by the manufacturer.
-Do not make any unauthorised modifications to the appliance.
-Do not touch the hot components of the product (ceramic glass, flue pipe) during normal operation.
-Never touch the appliance if you are barefoot and/or if you have wet or damp parts of the body.
-Use the appropriate button to switch off the electrical panel. Do not disconnect the power supply cable while the
appliance is operating.
-During the ignition phase and normal operation of the appliance, maintain the necessary safety distance and do not
remain standing in front of it.
-Keep children away from the appliance when it is running since they could get burned by touching its hot
components.
-Do not leave the packaging elements within reach of children or unassisted disabled persons.
-Children and inexperienced people must not be allowed to use the appliance.
-The appliance may be used by children no younger than 8 years of age and people with reduced physical, sensory or
mental capabilities, or those without experience of the appliance, as long as they are supervised or have received

-Children should not play with the appliance.
-User maintenance and cleaning operations should not be carried out by unsupervised children.
-Do not use the appliance in ways other than those indicated in this user guide.
-The appliance is designed for indoor use only.
-The appliance is designed for heating water and should therefore be connected to a plumbing system (radiators,
under-floor heaters, etc.). This system should be suitably designed and sized to distribute the power generated by
the appliance.

Pellet properties
The appliance has been tested with all types of pellets available on the market. The pellets must have the following
properties:
-Diameter 6 mm.
-Maximum length 35 mm.
-Maximum humidity content 8 –9 %.
-100% wood. Totally additive-free.
-Maximum ash residue 1.1 %.
To obtain good performance from the appliance, we recommend using good quality pellets. Pellets should be poured
into the tank using a shovel, and not directly from the bag.
Good quality pellets should have the following properties:
-Constant diameter cylinders with a smooth, shiny surface;
-There should not be a lot of sawdust inside the packaging;
-After grabbing a bunch of pellets and placing them into a container filled with water, good-quality pellets will sink and
poor-quality ones will tend to float;
-The quality certification data, in particular conformity to international standards such as EN14961-2, DIN 51731 and
O-NORM M7135, should be indicated on the packaging;
-The packages should be intact since pellets tend to absorb humidity. Humidity not only reduces the calorific value
and increases the amount of flue gases expelled, but also causes swelling of the product which may create problems
with the appliance.
The production of pellets must be compliant with some international standards (such as EN14961-2, DIN 51731 and O-
NORM M7135) which establish minimum values for quality checks on pellets. To facilitate the right choice of the
combustible material you can find below one of the most common certification marks identifying the quality of the pellets:
