MORCO MODELS D-61B, D61E AND G11E IMPORTANT INFORMATION INSTANTANEOUS MULTI-POINT WATER HEATER FITTED WITH DRAUGHT DIVERTER FOR NORMAL OPEN FLUED SYSTEM THIS HEATER IS MANUFACTURED IN ACCORDANCE WITH EN 26 NOTE: THIS APPLAINCE IS ADJUSTED FOR USE ON LIQUEFIED PETROLEUM GAS ONLY (BUTANE AND PROPANE GAS) BEFORE USING THIS APPLIANCE PLEASE READ THESE INSTRUCTIONS THOROUGHLY, ALWAYS RETAIN THE INSTRCTIONS FOR FUTURE USE.
A.1. - INSTRUCTIONS FOR USERS Technical instructions for use and maintenance WARNING: Before use, this appliance must be installed and adjusted by a competent person according the technical instructions in this manual. No attempt must be made to adjust this appliance for use with other gases. • LIGHTING THE PILOT • Fully depress the control knob and turn it to the left from the ● position to the position (pilot setting).
• WATER TEMPERATURE SELECTION To adjust the hot water temperature, turn the selector control to the right for hotter water and to the left for cooler water. • Whatever the water temperature selected, it remains constant even if there are fluctuations in the mains water pressure, (within the minimum and maximum range), due to the action of the automatic water flow regulator. • Never reduce the flow of hot water by using the appliance’s water inlet stopcock. This stopcock should always be fully open.
• CHECKING FOR SAFE OPERATION In addition to any annual service by a competent person, the user should carry out the following checks periodically and especially after any period of disuse. • PILOT BURNER Look through the pilot window and check the pilot flame is blue. There should be no yellow colour or laziness. • MAIN BURNER Look through the pilot window when the hot tap is open and the boiler is running. The burner flames should be all blue with no yellow/white colour or laziness.

• DESCRIPTION AND OPERATION • These gas water heaters are equipped with: • A stainless steel burner which can operate with Butane/Propane-Natural. • A pilot which will operate with either Butane/Propane. Ignition is by piezoelectric or by the battery powered electronic spark ignition. • A fully automatic soft start ignition system which needs no adjusting. This prevents any black smoke being given off during the main burner ignition process.

A.2.2. - INSTALLATION INSTRUCTIONS • RECOMMENDATIONS For the user The appliance must be installed, adjusted or adapted for use with another type of gas only by a qualified and competent person. It is both the quality as well as the correct installation which will ensure that your heater works properly. For the installation engineer A.2-2-A RELATED DOCUMENTS The following British Standards, Codes of Practice and other Regulations must be observed in the installation of the water heater.
• COMBUSTION GAS REMOVAL Flue: A draught diverter is fitted to the top of the water heater. The nominal flue size is 90 mm. (D61B, D61E) and 110 mm. (G11E). In exposed situations, twinwalled flue pipe should be used. A minimum length of vertically rising flue of 600 mm. must be provided to ensure the water heaters products of combustion are completely evacuated. If single wall flue pipe is being used which has to pass through combustible materials, provide a metal sleeve of 115 mm.
All permanent openings for ventilation should be designed to prevent the entry of vermin. Where screens are provided, they should not have apertures of less than 6 mm. or greater than 9 mm. in any direction, and they should be accessible for cleaning. Fine mesh screens shall be avoided as they are liable to become blocked with dust. The location of vents and the method of cleaning them should be stated in the Owners Handbook (Caravans and Boats).
• Ensure that all the washers are properly fitted. • Ensure all gas and water joints are sufficiently tight as not to leak. •WATER TIGHTNESS OF THE WATER CIRCUIT Allow water to flow into the heater by slowly turning on the water supply to the appliance. This will prevent possible damage due to hydraulic shocks on high pressure water supplies. Purge air from the water pipes by slowly turning on all the hot and cold water taps. Turn off the taps and check for leaks around the heater.

• CLEANING THE HEAT EXCHANGER To carry out the annual cleaning of the heating body, proceed as follows: - Turn off the gas supply - Turn off the supply of water to the appliance by turning off the appliance’s water inlet tap. - Turn on all the hot water taps to empty all the pipes. - Remove the heating body and clean it by gently brushing the fins. Soot if found should be removed by washing, and the cause of the sooting investigated.
PROBLEM No spark. Pilot fails to light. Pilot is difficult to light with spark. CAUSE ACTION The piezo electric ignitor is faulty. Replace with new one. Electrode is fractured. Replace with new one. Electrode is dirty. Clean it with bristle brush, etc. Spark gap is too wide. Adjust the gap to 3.2-4.0mm. Incorrect battery polarity. Check. Poor earth. Check. Flat battery. Check. Spark generator faulty. Check. Blocked injector. Clean using soft bristle only. No gas supply. Check.
PROBLEM Main Burner ignites when temp. adjusting knob is positioned at “HOT” but goes out when turned down to “WARM” position. CAUSE Insufficient water pressure Check water pressure at inlet to heater. Check for blockages in supply line or hot pipes and taps. If using a pump, check pump for faults. Water filter is clogged. Clean. Faulty diaphragm. Renew diaphragm. Restriction in heat exchanger Descale or replace. Main burner fails to shut off when hot water taps are closed.
PROBLEM CAUSE ACTION Even though temp. adjusting knob is turned to“HOT” Position, heated water is not hot enough due to too high a water flow rate. Water regulator is faulty. Faulty diaphragm in water control body assembly. Incorrect water control assembly fitted. Hot and cold water pipes crossed. Inspect and clean. Replace with new one. Even though temp. adjusting knob is turned to “WARM” position, heated water is too hot due to a low water flow rate. Water regulator is faulty.
PROBLEM Water heater operates at taps but not at shower. CAUSE ACTION Shower hose too small or kinked. Shower head restricted. Replace. Descale, remove blanking rings or replace. Restrict cold water supply to shower mixer. Set shower temperature at water heater rather than mixing cold water at mixer. Set correctly or replace High water pressure. Low water pressure. Shower mixer tap faulty or not set correctly. Water control assembly leaks from between anges. Frost damage. Replace damaged parts.
