Burner Cartridge for Webasto Air Top 3500 or AirTop 5000 - 67955A

Burner.

In the burner, the fuel, evaporating from the evaporating gasket, is distributed through the combustion chamber. In the combustion chamber burns the air-fuel mixture, thereby heating the heat exchanger.

During repair or routine maintenance of heaters, the following conversion works may be additionally performed:

• installation of an outdoor temperature sensor for optimal control of the heater operation.

• installation of the burner with a hood.

Installing the burner with a hood.

For the re-equipment of the heater, special repair kits are needed:

for 12 V heaters - Ident.-№ 679 84A;

for 24 V heaters - Id.-№ 679 56A

The kit includes: 1 burner with a hood, 1 combustion chamber, 3 screws EJOT FDS SF.

The burner is replaced as follows:

1. Remove the burner with a combustion chamber.

2. Insert the glow plug / flame sensor into the burner with the hood (cable in the direction of the hole for the cable gland in the hood) and fasten it with a screw.

3. Plug the glow plug / flame sensor cable through the hole in the blend.

4. Tighten the screw to a torque of 0.8 ± 0.08 Nm.

5. Insert the new seal into the groove of the heat exchanger flange.

6. Install the combustion chamber and secure with screws.

7. Tighten the screws to 4.0 ± 0.4 Nm. 8. Screw the burner with the hood into the combustion chamber.

9. Secure the hood and combustion chamber with EJOT FDS screws (10).

10. Tighten the EJOT FDS SF screws with a torque of 2.5 ± 0.25 Nm.

11. Insert the fuel intake sleeve into the heat exchanger housing.
