14 Termo JOHANNA
Heat output can be controlled by reducing the combustion air. To guarantee 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 output is not advisable.
3.7 Between-season operation
With outside temperatures above 15°C, the draught m ay be affected, resulting in a decrease in
heat output and therefore flue gases not completely exhausted (smell of smoke in the room). In this
case it is advisable to remove 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 static oven with capacity of 42 litres, covered entirely in stainless steel sheet and
provided with 2 grills 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 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.
Clean the oven every time it is used, following the instructions given in the section on cleaning.
The oven must only be used for its intended purpose, i.e. for cooking food; any other use is
improper and potentially dangerous.
3.9 Idle period and summer
In summer, it is advisable to clean the combustion chamber, ash pan, oven fume ducts, chimney
and flue; also, remove all residuals on the inside and outside of the stove, check all seals and
replace if necessary.
The appearance of the hotplate and other cast iron parts can be preserved by using neutral
vaseline.
At the end of maintenance operations, close the doors and air controls to prevent the 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.
