Cleaning Out The Ashes; Cleaning The Flue; Cleaning Of The Collection Casing Cooking Through The Oven; Lateral Handrail - Nordica ROSA Gebrauchsanweisung

12.8. CLEANING OUT THE ASHES

All the devices are equipped with a hearth grating and an ash drawer for the collection of the ashes.
It is suggested to empty periodically the ash drawer and to avoid it fills completely in order not to overheat the grating. Moreover, it is
suggested to leave always 3-4 cm of ash in the hearth.
CAUTION: The ashes removed from the hearth have to be stored in a container made of fire-resistant material equipped
with an air-tight cover. The container has to be placed on a fire-resistant floor, far from flammable materials up to the
switching off and complete cooling.

12.9. CLEANING THE FLUE

The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enough
draught of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance.
The device should be completely cleaned at least once a year or every time it is needed (in case of bad working and low yield). An
excessive deposit of soot can cause problems in the discharge of smokes and fire in the flue.
The cleaning must be carried out exclusively with cold equipment. This operation should be carried out by a chimney sweeper
who can simultaneously perform an audit of the flue (checking of possible deposits).

12.10. CLEANING OF THE COLLECTION CASING COOKING through the oven

The smokes collection casing can be cleaned either through the oven (remove the horizontal sheet metal which is the base of the oven
Picture 9 at page 42) the cooker or from the top.
See
To this purpose remove the circles of the cooking plate and disassemble the smokes pipe from the exhaust small trunk. Cleaning can be
made with a brush and a vacuum cleaner.
IMPORTANT: please verify that the deflectors are set as indicated in the FIGURA.
Pay ATTENTION that after cleaning all dismounted parts are reinstalled hermetically.

12.11. LATERAL HANDRAIL

The handles, the handrail and the tank water (cookers) should be cleaned to cold with a soft cloth and alcohol . DO NOT use abrasives
or solvents.

12.12. CLEANING OF THE HEARTH GRATE

IMPORTANT: if for whatever reason the grill is removed from the furnace, take care to reassemble it with the wider part of the slit facing

13. CALCULATION OF THE THERMAL POWER

There is not an absolute rule for calculating the correct necessary power. This power is given according to the space to be heated, but it
depends also largely on the insulation. On an average, the calorific value necessary for a properly insulated room is 30 kcal/h per m
an external temperature of 0°C).
Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 38 W/m
Let's suppose one wishes to heat a room of 150 m
x 38 W/m = 5700 W or 5,7 kW. As main heating, a 8 kW device is therefore sufficient.
