3.4. HOT AIR DUCT CONNECTIONS FOR

PRIMULA/ORCHIDEA MULTIAIR model

Once the stove is in position, you can begin installation of the hot air ducts.

First of all, select the amount of hot air that you want to come out of the

front and the back of the stove.

This simple operation is performed using the mechanical lever located

under the hopper cover (Figure 9). The greater the opening, the more air

will be directed to the front part and less to the back, and vice versa.

For further clarity, Figure 10 shows the distribution of the hot air

between the two outlets (front and rear) at maximum ventilation power

and taking one duct into account.

Do not adjust the air distribution with the lever when

the stove is on or without protection: DANGER OF

BURNS. The metal parts near the lever can reach a

temperature of up to 80°C .

Once you have adjusted the deflector, connect the rear hot air outlet

flange to the ducts and the nozzle. The rear hot air outlet has a diameter

of 80 mm. A pipe which is inserted in the wall must be properly insulated

so that it does not lose heat and so that air outlet is silent.

In the case of a dual duct (two hot air outlet

nozzles), the lengths of the pipes should be similar to

distribute the air uniformly, otherwise the air will

tend to flow more through the shorter or least

twisted duct.

The figures (Figure 11) show a simple example of ducting, seen both

from the rear and from the front of the stove.
