the room where the fireplace insert with water jacket is installed;
- do not fill up the combustion chamber with too much fuel, particularly with too shredded one, as
it may result in damage to the elements of front set and disturbances within the operation of the
fireplace insert with water jacket.
TO ENSURE SAFETY OF THE FIREPLACES INSERT WITH WATER JACKET THE PRODUCER RECOM-
MENDS THE USE OF:
- microprocessor Fireplace controller
- microprocessor pomp controller
- emergency power supply Unit zza-400-s
- emergency power supply Unit zza-300-a
9. The latest version - fireplace insert with safety coil pipe
To prevent water from overheating in the central heating system a built-in cooling coil pipe can be used.
In such case inside the water jacket a cool coil is installed. This coil is made of a copper pipe of 12mm
section. Both tips of the coils are led outside the fireplace.
To ensure best performance of the heat exchanger the safety device of the operation of the fireplace
insert itself (the process of heating up the water in the fireplace) with a thermostatic valve is at
the same time fitted. For this purpose the thermostatic valve is best. The thermostatic valve is not
controlled by pressure, it is controlled by water temperature. This valve is placed into the water inflow
pipe from the waterline to the coil. The thermostatic valve is connected with the temperature sensor
by means of a 1.3m-long-copper tube. The temperature sensor is settled on a stub pipe (23) prepared
spe- cially for this purpose; thanks to which it submerges directly in water that fills the water jacket,
consequently the thermostatic valve on the other end of the copper tube is controlled by the water
temperature. When the water in the fireplace reaches the temperature of 97°c the valve opens and
cold water from the water line flows through the coil tube. This way the water in the fireplace water
jacket is cooled. such solution has one more advantage, namely the thermal safety-device of the fire-
place operation does not need current. cold water from the water line may flow through the cooling
coil both ways and it has no impact on the effectiveness of the heat exchanger operation.
Maintenance
If the thermostatic valve is not tight, the water from the feeding system all the time flows in through
the coil tube regardless of the temperature of water in the water jacket. In regular conditions the
valve seat and head should be just cleaned from time to time from deposit and dirt by pressing the
red button a few times and rinsing the above mentioned parts with a stream of water. However, if it is
not enough, the following actions should be taken:
1. screw on the ball valve cutting off the water form the water line. This valve should always be under
the service connection with the thermostatic valve (i.e. under the pipe supplying water to the coil of
the heat exchanger).
2. screw off the hexagonal screw and pull out the valve conical head.
3. clean all elements of the thermostatic valve, in particular the valve seat, with the stream of running
water.
4. put together the thermostatic valve and finally screw on quite tightly the hexagonal screw.
Condensation
condensation inside the firebox is as a result of improper operation of your stove.
The effect of this can be:
- condensation forming on the inner walls of the firebox/stove and in extreme cases leakage out of
the unit,
- smoke exiting the stove back in to the room,
- dirty Glass and dirty combustion chamber,
- Loss of damper control due to sticking.
