NORMAL OPERATION
• Adjust the smoke regulator (where present) and load the wood into the firebox. Do not overload the chamber as this can cause
deformations in the apparatus and will render the guarantee void. (See recommended fuel load).
• The heat output can be regulated by using the adjustments on the front of the appliance (primary and secondary air). Opening these
controls will increase it. On first lighting, the optimum fire, with minimum emissions, will be achieved when the majority of the air enters
via the secondary air intake.
• As well as regulating the air intake via the manual adjustments, the draw on the flue will affect the rate of combustion and the heat
output of the apparatus. A strong pull on the chimney will need a reduction on the draw to the fire, while a weak pull will require extra
attention to the setting of the air intake controls. Check if the draw to the fire is correct by looking at the colour of the smoke being
emitted. It should be transparent. If it is white, it means that the controls have not been set correctly or the wood is too wet. If, on the
other hand, the smoke is black or grey, it means that the wood is not being completely burned and the secondary air intake must be
increased.
GENERAL CHIMNEY MAINTENANCE
• It is necessary a regular sweeping of the chimney and any connecting flue-pipe, cleaning the appliance flue-ways if incorporated,
and servicing the appliance. Regular sweeping means at least once a year for smokeless fuels and a minimum of twice a year for
bituminous coal, wood or any other non-authorised/smokey fuel. If a throat plate is incorporated, stress the need for its monthly
cleaning and describe the method. Ensure adequate access to cleaning doors where it is not possible to sweep the chimney through
the appliance. Where the chimney is believed to have served an open fire installation it is possible that the higher flue gas temperature
from a closed appliance may loosen deposits that were previously firmly adhered, with the consequent risk of flue blockage. It is
therefore recommended that the chimney be swept a second time within a month of regular use after installation. We woluld like to
make emphasise the importance of cleaning the appliance flue-ways, flue-pipe and chimney prior to lighting up after a prolonged
shut-down period
• If the insert is to be left unused for a prolonged period of time then it should be given a thorough clean to remove ash and unburned
fuel residues. To enable a good flow of air through the appliance to reduce condensation and subsequent damage, leave the air
controls fully open.
It is important that the flue connection, any appliance baffles or throat plates and the chimney are swept prior to lighting up after a prolonged
shutdown period.
The equipment must be thoroughly cleaned before each period of use.
CHIMNEY SWEEPING
When the wood is burnt slowly, it produces tars and other organic vapours that combined with the humidity they create the creosote (soot).
An excessive accumulation of soot may cause problems in the smoke outlet and even the smoke duct may suffer a fire. A chimney sweep
should perform this task and, at the same time, examine the smoke duct. During the cleaning tasks, it is necessary to remove the ash pan,
the grille and the smoke baffle plate in order to makes easier the fall of the soot.
It is recommended to use anti-soot envelopes during the operation of the insert at least once a week. These envelopes are placed directly on
the fire and you can buy them in the same Bronpi distributor where you bought your fireplace.
CLEANING THE GLASS
IMPORTANT:
Clean the glass only when it is cold in order to avoid its explosion.
You can use specific products such as vitro ceramic-cleaning products. Do not use aggressive or abrasive products that stain the
glass.
You can find Bronpi vitro ceramic-cleaning product in the same Bronpi distributor where you bought your fireplace.
EMPTYING THE ASHES
All inserts have an ash pan for the ash collection.
We recommend emptying the ash pan regularly in order to avoid that it is full completely so that the grille does not overheat. Moreover, we
recommend leaving 2-3 cm of ash on the base.
If the ashes continue to be hot, they should be kept in a fireproof container with an airtight lid. It should then be kept on a fireproof base, away
from inflammable materials, until the ashes have cooled completely.
Clean and check the fresh air intake at least once a year. The chimney must also be regularly swept (as mentioned above).
CLEANING THE EXTERNAL SURFACE
Do not clean the external surface of the insert with water or abrasive products because they may damage the fireplace. Use a feather duster
or a rag a bit wet.
PERMITTED AND PROHIBITED FUELS
Only dry/seasoned wood with a maximum water content of 20% may be burned and it must be stored in a dry place.
Logs should be between 20-30cm long, and the load should not be more than two thirds of the volume of the fire box.
Compressed Wood Briquettes may be used but should be used with caution because they have a higher heat output than wood and may
damage the apparatus.
Freshly cut (unseasoned) wood has approximately 60% water content. It is unsuitable for burning and makes lighting difficult as a large part
of the heat produced is needed to vaporise the water.
The high water content in the wood also has the disadvantage that when the temperature of the fire drops, the water condenses first in the fire
box itself then in the chimney, causing a build-up of soot and consequent risk of fire.
Coal unless authorized, carpentry off-cuts, wet or painted wood, plastics or rubbish must not be burned as the apparatus will be damaged
