4. Starting up and shutting down the heater
4.1. Heating phase
Set the main switch to position '1', and the work mode switch to heating (Grzanie). The burner is actuated. When the
temperature of 40 °C is reached, the fan switches on automatically. When the exhaust temperature reaches 80 °C, the
burner is switched off, and the exchanger enters a cooling cycle. The cycle is repeated after the burner is actuated again
by the limit thermostat.
WARNING!
Before switching off the main switch, make sure that the heat exchanger has cooled down sufficiently. This will extend the
heater lifetime.
The actuation of the Limit 2 thermostat may indicate damage to the heater. If the situation repeats itself, contact the
vendor service department.
4.2. Shutting the heater down
Set the work mode switch to position '0' -
burner off (Palnik wyłączony), the ventilator shall continue operating until the
exchanger cools down sufficiently, whereupon it will shut off automatically.
The ventilator may turn on again - this does not indicate of a flaw.
In order to shut down the entire heater, set the main switch to position '0'.
4.3. LIMIT 2 safety thermostat
When the air temperature exceeds 80 °C, the Limit thermostat shall shut down the burner, and later it will turn it on again
automatically. If the thermostat does not operate properly and if the air temperature rises to 100 °C, the main safety
thermostat Limit 2 shall switch the burner off. The thermostat diode on the electric cabinet shall light up (only 400 V
models). In such a case, wait for a few seconds for the fan to cool down the heat exchanger, and then press the
thermostat button located under the cover cap on the thermostat cabinet.
