SAFETY DURING THE OPERATION OF THE FIREPLACE INSERT WITH WATER JACKET
When using the fireplace insert with water jacket the following principles need to be observed:
- the fireplace insert with water jacket cannot work without water;
- do not pour water over the fire in the combustion chamber;
- the fire-resistant ceramics of front sets during fuel burning in the fireplace insert with water jacket
may reach the temperature exceeding 100°C;
- free natural inflow of air indispensable for fuel burning and room ventilation should be ensured in
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).
