USERS GUIDE C24, C30 For installation guide see reverse of book When replacing any part on this appliance, use only spare parts that you can be assured conform to the safety and performance specification that we require. Do not use reconditioned or copy parts that have not been clearly authorised by Ideal. April 2019 UIN 222352 A01 2 User’s THE BENCHMARK SERVICE INTERVAL RECORD MUST BE COMPLETED AFTER EACH SERVICE Ideal Heating, is a member of the Benchmark scheme and fully supports the aims of the programme. Benchmark has been introduced to improve the standards of installation and commissioning of central heating systems in the UK and to encourage the regular servicing of all central heating systems to ensure safety and efficiency. All Gas Safe Register installers carry a Gas Safe Register ID card, and have a registration number. Both should be recorded in the Benchmark Commissioning Checklist. You can check your installer by calling Gas Safe Register direct on 0800 4085500. 1. INTRODUCTION The i-mini C is a combination boiler providing both central heating and instantaneous domestic hot water. Featuring full sequence automatic ignition and fan assisted combustion. Due to the high efficiency of the boiler, condensate is produced from the flue gases and this is drained to a suitable disposal point through a plastic waste pipe at the base of the boiler. A condensate ‘plume’ will also be visible at the flue terminal. SAFETY Current Gas Safety (Installation & Use) Regulations or rules in force. In your own interest, and that of safety, it is the law that this boiler must be installed by a Gas Safe Registered Engineer, in accordance with the above regulations. In IE, the installation must be carried out by a Registered Gas Installer (RGII) and installed in accordance with the current edition of I.S. 813 “Domestic Gas Installations”, the current Building Regulations and reference should be made to the current ETCI rules for electrical installation. It is essential that the instructions in this booklet are strictly followed, for safe and economical operation of the boiler. ELECTRICITY SUPPLY This appliance must be earthed. Supply: 230 V ~ 50 Hz. The fusing should be 3A. IMPORTANT NOTES • This appliance must not be operated without the casing correctly fitted and forming an adequate seal. • If the boiler is installed in a compartment then the compartment MUST NOT be used for storage purposes. • If it is known or suspected that a fault exists on the boiler then it MUST NOT BE USED until the fault has been corrected by a Gas Safe Registered Engineer or in IE a Registered Gas Installer (RGII). • Under NO circumstances should any of the sealed components on this appliance be used incorrectly or tampered with. • This appliance can be used by children 8 years and above. Also persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, provided they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision. CONTENTS 1.

CONDENSATE DRAIN This appliance is fitted with a siphonic condensate trap system that reduces the risk of the appliance condensate from freezing. However should the condensate pipe to this appliance freeze, please follow these instructions: a. If you do not feel competent to carry out the defrosting instructions below please call your local Gas Safe Registered installer for assistance. b. If you do feel competent to carry out the following instructions please do so with care when handling hot utensils. Do not attempt to thaw pipework above ground level. If this appliance develops a blockage in its condensate pipe, its condensate will build up to a point where it will make a gurgling noise prior to locking out an “L 2” fault code. If the appliance is restarted it will make a gurgling noise prior to it locking out on a failed ignition “L 2” code. To unblock a frozen condensate pipe; 1. Follow the routing of the plastic pipe from its exit point on the appliance, through its route to its termination point. Locate the frozen blockage. It is likely that the pipe is frozen at the most exposed point external to the building or where there is some obstruction to flow. This could be at the open end of the pipe, at a bend or elbow, or where there is a dip in the pipe in which condensate can collect. The location of the blockage should be identified as closely as possible before taking further action. 2. Apply a hot water bottle, microwaveable heat pack or a warm damp cloth to the frozen blockage area. Several applications may have to be made before it fully defrosts. Warm water can also be poured onto the pipe from a watering can or similar. DO NOT use boiling water. 3. Caution when using warm water as this may freeze and cause other localised hazards. 4. Once the blockage is removed and the condensate can flow freely, restart the appliance. (Refer to “To Start the boiler”) 5. If the appliance fails to ignite, call your Gas Safe Registered engineer. Preventative solutions During cold weather, set the central heating temperature knob (B) to maximum (must return to original setting once cold spell is over). Place the heating on continuous and turn the room thermostat down to 15ºC overnight or when unoccupied. (Return to normal after cold spell). 5. GENERAL INFORMATION BOILER PUMP The boiler pump will operate briefly as a self-check once every 24 hours, regardless of system demand. MINIMUM CLEARANCES Clearance of 165mm above, 100mm below, 2.5mm at the sides and 450mm at the front of the boiler casing must be allowed for servicing. Bottom Clearance Bottom clearance after installation can be reduced to 5mm. This must be obtained with an easily removable panel, to enable the system pressure gauge to be visible and to provide the 100mm clearance required for servicing. EXPANSION NOTE. If a water meter is fitted into the incoming water mains there may be a requirement for a domestic hot water expansion vessel Kit. Contact a Gas Safe Registered Engineer or in IE a Registered Gas Installer (RGII). ESCAPE OF GAS Should a gas leak or fault be suspected contact the National Gas Emergency Service without delay. Telephone 0800 111 999. Ensure that; - All naked flames are extinguished - Do not operate electrical switches - Open all windows and doors CLEANING For normal cleaning simply dust with a dry cloth. To remove stubborn marks and stains, wipe with a damp cloth and finish off with a dry cloth. DO NOT use abrasive cleaning materials. MAINTENANCE The appliance should be serviced at least once a year by a Gas Safe Registered Engineer or in IE a Registered Gas Installer (RGII). 6 User’s 6. POINTS FOR THE BOILER USER Note. In line with our current warranty policy we would ask that you check through the following guide to identify any problems external to the boiler prior to requesting a service engineer’s visit. Should the problem be found to be other than with the appliance we reserve the right to levy a charge for the visit, or for any pre-arranged visit where access is not gained by the engineer.
