REPLACING THE FILTER, NOZZLE AND THE GASKET KIT
REXENER BIOHEATER WATER HEATER
NOTE! Check if you have a filter in your tank. If not, please contact Rex
Nordic’s service.
We’ll send you a new tank free of charge.
Before starting, unplug the power cord.
If your heater has a damper in front of the burner, remove it before you start servicing.
Disconnect the power cables of the burner.
Remove the fuel filter and replace it with a new one.
Remove the burner’s fastening nuts on both sides (2 pcs) and remove the burner.
Open the nozzle damper screws (4 pcs).
Lift the damper out to access the igniter screw and air flow regulator screw.
First remove the air flow regulator screw and loosen the igniter out of the nozzle frame.
Then remove the air flow regulator carefully by lifting it up to reveal the nozzle.
Remove the nozzle with a 16 mm and 19 mm spanner.
Check the nozzle chamber for impurities and clean it before installing the new nozzle.
Finger-tighten the new nozzle into place, and finish by tightening it firmly with spanners.
After this, clean the air flow regulator and damper and install them into
place.
First place the air flow regulator on the nozzle frame. Then tighten the
igniter screw, adjust the air flow regulator to the correct position in the
centre of the igniter and tighten the screw.
Put the damper in its place and make sure that the guiding groove is in the correct position. Tighten the screws. The burner is now ready to be connected to the heater.
Remove the gasket from the heating pipe and install the new one.
- Install the burner and tighten the screws. Before tightening, check the position of the burner to ensure that it is in the centre of the heating pipe by confirming that the fastening nuts are symmet-rically in the appropriate grooves.
- Install the fuel hose and power cables.
- Connect the power cable to the power socket and press the power switch to activate the heater.
- Remember to bleed the burner to discharge any air from the system. (Bleeding instructions can be found in the manual.)
- Test run the device for at least 10 min and ensure that everything is in order. The heater is ready for use.
SOOTY AIR NOZZLE?
If the air nozzle is extremely sooty, the air nozzle must also be replaced!
