Where the air is taken from another room that room must contain an air inlet as described in 6.1. 6.3 There must be sufficient clearance around the appliance to allow proper circulation of ventilation air. The clearances required for installation and servicing will normally be adequate for ventilation. See Section 4.4. ROOM SEALED BALANCED FLUE MODEL ( RS ) 6.4 The appliance does not require a separate vent for combustion air. 6.

Two Pipe System A two pipe system will automatically vent the air back to the oil tank. Turn on the boiler thermostat and allow the burner to run through to lockout. Wait two minutes and reset the burner control box. Repeat the procedure untill the burner fires and runs in a steady state.

DANESMOOR 12-14, 15-19, 20-25, 26-32, 32-50, 50-70 FLOOR-STANDING OIL-FIRED PRESSURE-JET BOILERS USER INSTRUCTIONS & CUSTOMER CARE GUIDE
EXCELLENCE COMES AS STANDARD Thank you for purchasing a Danesmoor oil-fired central heating boiler. Danesmoor oil boilers are made by Worcester Heat Systems and the strictest quality control standards ever demanded are applied throughout every stage of production. Indeed, Worcester Heat Systems have led the field in innovative boiler design and performance for more than 30 years.
GENERAL INFORMATION To ensure you get the very best from your new Worcester Danesmoor oil boiler, please read these notes and instructions carefully. ELECTRICAL CONNECTION A mains cable should be connected to a double pole isolator with a contact separation of 3 mm on all poles and supplying the appliance and controls only. The mains supply for your Danesmoor boiler is 230/240 volts AC-50Hz. Your boiler must be earthed and protected by a 5-amp fuse.
SERIAL NUMBER Your boiler serial number and model number should always be quoted in any contact with Worcester Heat Systems. This will help identify spare parts and also avoid confusion and delays during any service call-out. You will find these numbers on top of the electrical control box cover plate, and access can be gained by removing the top panel of the boiler casing.
(d) Turn the thermostat control knob to the desired position (see Fig. 2: temperature control). (e) Your boiler will now commence a start sequence, in which a pre-ignition period of approximately 15 seconds is followed by a supply of atomised oil being introduced into the combustion chamber. Ignition then occurs, followed by a post-ignition period of approximately 20 seconds.
MANUAL RESET OVERHEAT THERMOSTAT Sealed system installations require the use of an overheat thermostat which has to be reset by hand. Your boiler is fitted with this thermostat as standard and may be reset by pressing the button shown in Fig. 1. Access is gained by removing the case front panel. If either thermostat persistently cuts out then your boiler requires attention and you should call either your installer or a service engineer.
OPERATING YOUR PROGRAMMER CONTROLS Full instructions on how to install and operate the optional faciamounted programmer are included with the programmer kit. If your boiler operates on gravity feed, the system will only function correctly on heating if the programmer switches on the hot water programme at the same time. To ensure that this is always the case, the programmer is supplied with a gravity system switch on the rear of the unit; this switch must be set to G by your installer.
A call-out charge will be made where: ● ● ● ● The appliance has been installed for over 24 months The appliance has been installed for more than 1 year but less than 2 years and has not had a first annual service by an approved company. OR Our Field Service Engineer finds no fault with the appliance (see note). OR The cause of breakdown is misuse or with other parts of your plumbing/heating system, or with equipment not supplied by Worcester.
MAINTAINING YOUR BOILER’S EFFICIENCY & PERFORMANCE Your new Worcester Danesmoor oil-fired 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 your boiler receives regular, competent servicing and annual maintenance checks beyond the initial 24 month guarantee period.
