Cleaning Of The Collection Casing Cooking Through The Oven; Calculation Of The Thermal Power - La Nordica ROSA Manual Del Usuario

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 See Picture 9) the cooker or from the top.
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 Picture.
Pay ATTENTION that after cleaning all dismounted parts are reinstalled hermetically.

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 (for an external temperature of 0°C).

Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 35 W/m
Let's suppose one wishes to heat a room of 150 m
150 m x 35 W/m = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.
