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.
VENTILATION OF ROOM SEALED FANNED
FLUE (RSF) APPLIANCES
These are room sealed appliances and any ventilation openings
in a wall or door must not be obstructed. Do not allow the flue
terminal fitted on the outside wall to become obstructed or damaged.
NOTE: Do not place anything on top of the appliance. If the
appliance is fitted in a compartment do not use the compartment for
storage purposes unless it conforms to the requirements of
BS 6798:1987: Section 6. It is essential that the airing space is
separated from the boiler space by a perforated non-combustible
partition as described in BS 6798:1987.
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. Three star service cover
from British Gas can offer comprehensive cover for your central
heating - please call 0845 9 60 50 40 for further details.
WARNING
If a gas leak exists, or is suspected, turn off the gas supply to the
appliance at the service cock and consult your local service engineer.
Do not touch any electrical switches to turn them either on or off.
Open all windows and doors. Do not smoke. Extinguish all naked lights.
CLEANING
Do not use abrasive cleaners on the outer casing. Use a damp
cloth and a little detergent.
