3.5 Normal operation
Remove the ash from the grate each time before loading fuel. Put 2-3 pieces of wood on the bed of embers. Given
the large capacity of combustion chamber it is advisable not to exaggerate, but to load up to 2-3 pieces of wood at
a time. For normal operation set the primary air control to halfway and with the damper closed. Overloading does
not increase heat output, but will overheat the stove, damaging it.
3.5.1 Setting the stove for BOILING water
Adjust the damper to position "A" for the direct discharge of fumes with the primary air control fully open.
With this setting, load wood with the normal hourly amounts.
3.6 Operation with slow combustion
Heat output can be adjusted by reducing the combustion air. To ensure operation for many hours at low heat, the
primary and secondary air controls must be opened at minimum.
With partial feed operation, a patina may form on the glass due to the low temperature in the combustion chamber.
In any case, a continuous fire with low heat is not advisable.
3.7 Operation in low season
With outside temperatures above 15°C, the draught may be affected, resulting in a decrease in heat output and
with flue gases not being completely exhausted (smell of smoke in the room). In this case it is advisable to clean
the ash from the grate and increase the combustion air. Put less fuel on the fire and clean the grate more
frequently.
3.8 Oven operation
The stove has a 45-litre static oven, covered entirely in stainless steel sheet and provided with 2 racks for holding
trays.
A thermometer installed on the glass of the enamelled door shows the oven temperature.
When the stove is lit for the first time, the oven should only be used after 1-2 hours of operation at 200-250°C with
the oven door left ajar to eliminate fumes produced by manufacturing process residuals such as grease, oil and
sealants.
To reach adequate cooking temperatures, make sure the damper lever is in position "A"
and if necessary increase the primary and secondary air.
Clean the oven every time it is used, following the instructions given in the section on cleaning.
3.8.1 Setting the stove for BISCUITS
Light the stove using a normal load of wood, primary air 2/3 open, damper in position "Z" and proceed as follows:
- wait until the thermometer reaches ( 190
- load single pieces of wood, stabilising the oven temperature at 200 °C;
- insert the pan with biscuits in the low position for 25-30 minutes (slow cooking) or the middle position for 15-20
minutes (quick cooking);
- if necessary, turn the pan halfway through cooking.
The oven must only be used for its intended purposes, i.e. cooking foods; any other use is improper and
dangerous.
3.9 Idle period and summer
In summer, it is advisable to clean the combustion chamber, ash pan, fume ducts in the oven, the chimney and
flue; also, remove all residuals on the inside and outside of the stove, check all seals and replace them if
necessary.
The appearance of the hotplate and other cast iron parts can be maintained by applying neutral vaseline.
At the end of maintenance operations, close the doors and air controls to prevent dust, etc., from entering.
If the stove is not going to be used for a long period, after the above operations and disconnecting from the flue, it
is advisable cover it with a protective cloth and store in a safe and protected place.
4 – ROUTINE STOVE CLEANING AND MAINTENANCE
Good maintenance will help keep improve the stove's efficiency and prolong its service life.
Daily, before lighting the fire, clean the grate and remove any unburnt wood and ash from the ash pan zone.
4.1 Removing ash
The HELENA – MINI HELENA stove has a removable grate which should be cleared of ash, using the poker
supplied, every time before loading fuel.
Make sure to empty the ash pan regularly, as accumulated ash under the grate will obstruct the flow of combustion
air. The grate will get too hot and may be damaged.
To prevent the risk of fire, allow the ashes to cool outdoors in a metal container or in the stove and
eliminate them in compliance with the current local regulations.
