3.6.4. Flue offtake and gas supply by means of two separate pipes
In order to use a system of two separate pipes:
•
Unscrew a cover in an upper part of the combustion chamber in the point where an air supply system is connected to the
water heater (Fig. 3.6.1),
•
Keep a gasket which is placed under the cover to use it later,
•
Screw down an adapter

Note: Horizontal air-flue pipe should be installed with a slope ~3
º
(Fig. 3.6.4.1 and Fig. 3.6.4.2.) so that the raining water coming into pipes will not flood the boiler
and flow out the building.
It is not necessary to install draining board, if the slope has been made.
The hose for condensate drain must be properly siphoned.

4. HEATER OPERATION
4.1 Preparing the heater for the first start-up
Before proceeding with the first start-up of the water heater, it is necessary to:
•
fill a water system with water so as after turning on water taps water may flow.
•
Connect the water heater to the electric supply (a red diode will light on the control panel)
•
turn on a gas knob (if you use LPG, turn on a valve placed on a gas cylinder).
4.2 Starting-up the heater
Use buttons „MIN” and „MAX” (Fig. 4.3.1) and set the required tap water temperature. After turning on a water tap, the water
heater will automatically actuate.
During the first start-up, release air from the system and the gas fittings.
During the first start – up gas is not ignited in a burner and in a consequence the anti – outflow protection closes a gas valve for
30 s (E1 error code will be displayed on LCD). After 30 s the control system actuate the water heater. After 3 ignition trials (2
trials for LPG) the water heater will be blocked. It is signalled with a E1 error code permanently displayed on LCD,
In order to cancel the error, turn off a water tap and then turn it on again. Repeat this action until air from a gas system will be
released.
After this the water heater is ready to be used.
