Note: This device works irrespective of any room thermostat setting and only protects the boiler. Al- ways ensure that adequate frost protection is given to the entire system where necessary. If the boiler is to be out of use for any long periods during severe weather conditions, it is recom- mended that the whole system, including the boiler, be drained to avoid the risk of freezing. If in doubt, consult your Installer/Service Provider. Draining and filling Caution: The boiler is installed as part of a sealed system which must only be drained and filled by a competent person. Note: If there is persistent loss of system pressure, indicated by the pressure gauge, you must consult your Installer/Service Provider. Heating safety valve CAUTION: A safety valve with a discharge pipe is fitted to this boiler. The valve MUST NOT BE TOUCHED except by a com- petent person. If the valve discharges at any time, switch the boiler off and isolate it from the electri- cal supply. Contact your Installer/Service Provider. To ensure the continued efficient and safe opera- tion of the boiler, it is recommended that it is checked and serviced at regular intervals. The fre- quency of servicing will depend upon the installa- tion conditions and usage but, in general, once a year should be enough. Cleaning The boiler casing can be cleaned with a damp cloth followed by a dry cloth to polish. Do not use abrasive or solvent cleaners. Boiler casing CAUTION. Do not remove or adjust the casing in any way, as incorrect fitting may result in faulty op- eration. If in doubt, contact your Installer/Service Provider.
