Please read these instructions and follow them carefully for the safe and economical use of your boiler. 4 Important Information Gas Safety (Installation and Use) Testing and Certification In your own interests and that of safety, it is gas appliances have been installed by a competent person in accordance with the current issue of these regulations. Gas Category This boiler is for use only on G20 natural gas but can be converted for use on G31 propane. Electrical Connection The boiler MUST be earthed. The boiler MUST be connected to a permanent 230V ac, 50Hz supply, fused at 3A. Connection of the whole electrical system of the boiler, including any heating controls, to the electrical supply must be through one common isolator. The colours of three core flexible cable are, blue - neutral, brown - live, green and yellow - earth. This boiler is certificated to the current issue of EN performance and safety. It is important that no alteration is made to the boiler unless approved, in writing, by Glow-worm. Any alteration not approved by Glow-worm, could invalidate the certification, boiler warranty and may also infringe the current issue of the statutory requirements. CE Mark This boiler meets the requirements of Statutory Instrument, No. 3083 of the Boiler (Efficiency) Regulations, and therefore is deemed to meet the requirements of Directive 92/42/EEC on the efficiency requirements for new hot water boilers fired with liquid or gaseous fuels. Type test for purposes of Regulation 5 certified by: Notified body 0087. Product/production certified by: Notified body 0086. The CE mark on this appliance shows compliance with: 1. Directive 90/396/EEC on the approximation of the laws of the Member States relating to appliances burning gaseous fuels. 2. Directive 73/23/EEC on the harmonisation of the Laws of the Member States relating to electrical equipment designed for use within certain voltage limits. 3. Directive 89/336/EEC on the approximation of the Laws of the Member States relating to electromagnetic compatibility. 5 Boiler Design and Description These boilers are designed for use as part of watercentral heating system with fully pumped circulation. Thepump, expansion vessel and associated safety devices allfitted within the boiler. The intelligent control system is designed for both simpleoperation and maximum control. Once the controls are set the boiler operates automatically. Pluming from flue terminal Like all condensing boilers it will produce a plume ofcondensation from the flue terminal in cool weather. This isdue to the high efficiency and hence low flue gas temperatureof the boiler. It is normal and not a fault indication. Compartment or Cupboard Installations Ventilation is not required for compartment or cupboardinstallations. Do not use the compartment or cupboard for storage.

Frost Protection With the gas and electric supplies ON and irrespective of any room thermostat setting, the integral frost protection device will operate the pump when the temperature of the boiler water falls below 8OC. The pump will stop after 10 minutes if the temperature is higher than 10OC or has already reached 35OC. The burner will only activate if the boiler temperature does not reach 10OC after 30 minutes or at any time if the temperature drops to 5OC. The burner will switch off when the temperature reaches 35OC. NOTE: Any other exposed areas of the system should be protected by a separate frost thermostat. As a safety feature the boil...
