Ignition Turn the switch from position [0] to [1], to start the ignition in the control burner. Keep the switch in that position for approx. 10-20 seconds until the ignition indicator lamp (L) turns red. Turn the switch (K) to position [2] and then directly to position [3]. A soft noise should be heard when the ignition takes place in the main burner. Repeat from step 1 if ignition doesn’t begin in the main burner. The heater shuts down when the switch is in position [0]. Note! It is not possible to adjust the heater effect. Number key for the ignition switch 1 = ignition 2 = control burner 3 = main burner 0 = stop WINTER USE If there is a risk of freezing, the heater must be emptied of water after use. Self-circulation stops when the heater is turned off and the small amount of water remaining inside the heater can easily freeze and damage the heat exchanger if undrained. If water is to be left in the tub, make sure that the heating pipes can still be closed and emptied so that the heater itself can be drained. If the heater is correctly installed it will drain itself when the tub is emptied.
