MAINTAINING YOUR BOILER
Your new boiler represents a long term investment in a reliable, high quality product.
In order to realise its maximum working life and to ensure it continues to operate at peak
efficiency and performance, it is essential that servicing and maintenance checks are performed at
least once a year by an OFTEC engineer or other suitably qualified person.

When your boiler requires servicing please contact a Worcester, Bosch Group contact centre

Maintenance tips:
Regularly check the oil level in the tank.
Regularly check the system pressure, ask your installer for guidance.
Do not obstruct the flue outlet or the air inlet.
USE IN HARD WATER AREAS:
In exceptionally hard water areas a device to prevent scale formation may be fitted. Installation of
a scale inhibitor assembly should be in accordance with the requirements of the local water
company. An isolating valve should be fitted to allow for servicing.
