Ceiling (floor) protection
Ceilings without a sufficient lateral distribution (e.g. wooden ceilings) must be protected by a 6
cm thick concrete layer and 6 cm thick thermal insulation layer, where the fireplace insert is
situated. Consulting a structural engineer is recommended. If the floor, where the fireplace insert
will be situated, has an adequate lateral distribution a 6 cm thick thermal insulation layer is
enough.
The floors in front of the fireplace insert
A floor made of combustible material in front of the fireplace insert must be protected by an
adequate non-combustible material layer. Dimensions of this non-combustible area must be at
least: 800mm in the sideways direction of the opening side (min.dimension H on pic.1) and
400mm to the front in the direction of the opening side (min.dimension S on pic.1)

Before starting the unit for the first time it is necessary to let authorized person do the
inspection in accordance with national standards
.
Fire protection in a heat radiation area
A minimum distance of 80 cm forwards and sideways must be retained in front of the firebox hole - (furniture, carpets,
plants etc.)
Protection against injuries
Do not forget that heaters have hot surfaces. Use the enclosed protective glove when working with the fire. You could be in a heat radiation area
(80 cm) only during mending, and if there is further contact, the skin can be burnt. Keep the fireplace out of the reach of children.
Application and activation
Acceptable fuel, economical and ecological operation:
The fireplace insert is designed to use wood as fuel. The water content is max. 20% of dry weight. Logs should be stored in a dry and well
ventilated place for two years. Using wet logs leads to smoke with a tar condensation which could damage the chimney. In any case there is
excessive environmental pollution. Logs should be 30 cm.
Wood is a very gaseous fuel and needs a lot of secondary air. Regulation with the help of slow or permanent burning is not possible with this
kind of fuel. Heating output during wood burning is determined by the amount of the fuel used.
The most ecological and economical is dry wood burning because the heating quality of fresh wood is lower than that of dry wood.
As for burning waste, it must be stressed that burning material such as plastic material, cardboard, painted wood, etc. are harmful for your
fireplace insert and furthermore is prohibited by the Emission Act. It is allowed to use firelighters, paper and small wood for lighting a fire only.
Do not use combustible liquid e.g. petrol, alcohol for lighting a fire and do not store similar kinds of liquid near your
fireplace insert!
The first lighting
The fireplace insert should start with a small fire at first, so as not to harm it by very fast temperature rise. Smoke and the smell of burning which
may appear during the first lighting of a fire is a result of coating thermal curing. The room should be well aired during first heating.
Before the first use, check if all removable parts of the fireplace (block, deflector, grate and ash hole) are in the right
position – in accordance with the Equipment Certificate.
Lighting a fire
Stoking a fireplace insert is operated through a firebox door. At first bank up the fire with 2 big logs on the bottom of the firebox, then 2-3
smaller logs across (1,5 to 2 kg of wood). Then add some paper, paperboard or firelighter, then wood chips and finally small pieces of wood. Set
on fire and open all air inflows at maximum (open fully air input or keep the front door little bit open). When the fire is burning well, close the
door and regulate required output. When wood is white-hot, burning down, stoke fuel again when there is high heat inside.
The optimum amount of fuel is recommended in the Equipment Certificate.
Due to overloading of the insert, nonreturnable changes will occur!
We can provide a guaranty for our products only when the insert is not overloaded and service instructions are kept!
Fireplace insert with chamot lining:
Chamot parts need to be heated up very slowly. Big temperature changes can cause cracking of the chamot parts. The broken chamots do not
affect the function of the fireplace insert. In case of broken chamot, special paste is supplied by manufacturer to fill it in.
It is important to use dry wood only (max 20% of humidity). In other case fire-bricks are overloaded, the amount of ash is bigger and the wood
is not fully burnt.
The fireplace insert is overloaded when the big amount of fuel is added.
The recommended one-hour fuel flow is written in the Equipment certificate.
Setting of air inlet during hands-off operation
Hot air inserts are provided with the air input in bottom part underneath the door. With the help of this regulation you can regulate
combustion air input (primary air) and also the glass flushing.
The proportion of the air amount in each intake is regulated automatically. There
is a possibility of nearly closing of the regulation for long term operation.
Fuel addition
Apart from using the suitable fuel and having an adequate chimney draught, the clearness of
the glass front is influenced by the way the fireplace is used. It is recommended to add only
one layer of fuel. About 5 - 10 seconds before you open the firebox door you should close the
discharge valve (engaged position – closed, disengaged position – open), to stop smoke
leakage from the firebox to the room. After adding fuel close the firebox door again. Then
open all the discharge valves to reduce the rate of fuel burning. When fuel burns, change the
regulating again as above.
