VENTILATION OF ROOM SEALED FANNED
FLUE APPLIANCES
These are room sealed appliances and do not require any
ventilation openings. Do not allow the flue terminal fitted on the
outside wall to become obstructed or damaged.

USE IN HARD WATER AREAS

Normally there is no need for scale protection. However, in areas
of exceptionally hard water supply it is recommended that an In-Line
scale inhibitor be fitted.
Installation should be strictly in accordance with the
requirements of the local Water Company. An isolating valve to
facilitate servicing should be incorporated.
The water hardness may be determined using the standard test
paper or by reference to the local Water Company.
Further information may be obtained from Worcester Heat
Systems Technical Helpline.

CIRCULATING PUMP

This may be fitted with a speed adjuster. If so it will be factory
set at maximum and should not be changed.
FROST PRECAUTIONS
If the appliance is not to be used for a long period of time and
there is a likelihood of freezing, then the appliance should be drained.
The Worcester Heat Systems Technical Helpline will advise you on
suitable frost precautions. For short periods the built-in frost
protection of the appliance will be adequate.
SERVICE
Annual servicing is important in order to ensure continuing high
efficiency and long life for your appliance. In the event of any
difficulty in making suitable servicing arrangements, Worcester Heat
Systems Limited or other competent persons will discuss regular
servicing arrangements and offer a comprehensive maintenance
contract.
CLEANING
Do not use abrasive cleaners on the outer casing. Use a damp
cloth and a little detergent.
Under no circumstances should any seal on the boiler be broken.
