4.- GENERAL INSTALLATION REQUIREMENTS 4.1 RECOMMENDATIONS - Ventilation requirements as stated in this manual must be observed. - Minimum clearance as stated in the technical data must be observed. FOR THE USER This appliance must be installed, adjusted or adapted for use with another type of gas, only by a qualified and competent person. Its quality and a correct installation will ensure that your heater works properly. 4.
4.4 VENTILATION REQUIREMENTS The following notes are for general guidance: - The Morco MORCO FEB-24ED 3! is a room sealed appliance and needs no purpose provided combustion air ventilation. - If the boiler is to be built into a small cupboard or compartment (i.e. at minimum clearances)and overheating can be forseen (i.e. close proximity to a cooking appliance etc) permanent air vents are recommended for cooling purposes in the cupboard or compartment .
Expansion vessel. The following table gives the maximum system volume that the integral 7 l expansion vessel can sustain under different temperature conditions. If the system volume exceeds that shown, an additional expansion vessel must be fitted and connected to the heating system primary return pipe as close as possible to the appliance. If an extra vessel is required, ensure that the total capacity of both vessels is adequate. If the pressure gauge indicates 2.
5.- INSTALLATION INSTRUCTIONS mostat is 24V (normally closed). Any 24V controls may be used, but gold contacts are recommended. 5.1 BOILER PACKAGING The boilers are supplied in different packagings: DO NOT under any circumstances use a mains supply to the stat as you will blow the P.C.B. in the boiler. Only voltage free switching stats should be used. - Boiler - Flue system (separate packaging) Connection of a room thermostat (optional) .
External Probe Curves 5.4 WATER AND GAS CONNECTION Connect the boiler up in such a way as to leave the connecting pipes self supporting and free from any stress. Check that the gas pipe complies with the requirements of section 4.6 In order for the boiler to function correctly and to have a long working life, the central heating system must be properly designed, making sure that the temperand the return will ature di erence between the not be greater then 20°C. 5.
6.- COMMISSIONING INSTRUCTIONS Before commissioning the appliance, the whole gas installation including the meter (if fitted) MUST be purged and tested for gas soundness. IMPORTANT: open all doors and windows, extinguish naked lights, and DO NOT SMOKE whilst purging the gas line. Before commencing the commissioning procedure, ensure that the central heating system and the domestic hot and cold water system have been flushed.
