SECTION 3 INSTALLATION External wiring to the water heater(s) must be installed in accordance with current I.E.E. ELECTRICAL Regulations for the wiring of buildings and to any Local Regulations that may apply. SUPPLY The Auto Ignition Heater is designed to operate from a 220/240V, 1Phase supply. The fuse rating is 5 amps.
INSTALLATION SECTION 3 Your Andrews Water Heater is a Direct Fan Flued Gas Water Heater where all air for FLUE combustion is obtained from the outside atmosphere and all flue gases are charged to the SYSTEMS outside atmosphere. The flue system is a single coaxial (pipe within pipe) design where the flue products are discharged through the inside flue tube and the combustion air supply surrounds the flue surrounded by the outside pipe.
SECTION 3 INSTALLATION Installation Procedure HORIZONTAL AND VERTICAL Determine location of flue exit. DIRECT FLUE 1. The supplied kit includes a horizontal (through the wall) flue terminal, an elbow, LENGTHS flue connector clamps and 2m (6.5ft) of coaxial flue pipe. The 150mm (6in) diameter flue system is also supplied with a 200mm (8in) to 150mm (6in) reducer for the waterheater flue connection.

SECTION 3 INSTALLATION FLUE INSTALLING THE FLUE TERMINAL SYSTEMS NOTE! The horizontal flue terminal supplied may be used through outside walls up to 600mm (24in) thick. 1. Horizontal flue Terminal (Through the Wall) supplied a) Cut an opening of at least 165mm (6.5in) diameter through the outside for the 58.7kWh input models or 216mm (8.5in) for the 88kWh and 105.6kWh input models.
INSTALLATION SECTION 3 2. Vertical Flue Terminal (Through the Roof - Optional) FLUE a) Determine the exact location where the roof flue terminal will exit the roof, ensuring SYSTEMS the flue system clears all obstructions. For pitched roofs, the flue cap must be the distance above the roof line as specified, (300mm to base of Flue Clamp, minimum).
SECTION 3 INSTALLATION FLUE Straight End SYSTEMS (Ungasketed) Gasket End Ribs Locked Beneath Fig 7. Gasketed Clamp g) The last pipe section may be cut to fit the distance required to reach the water heater flue connections. First, install the supplied condensate trap with crimped end into the gasketed end of the elbow (horizontal flue installations) and clamp the condensate tee and elbow together.
INSTALLATION SECTION 3 The following notes are intended to give guidance: AIR SUPPLY Where the heater is to be installed in a room, NO VENTS ARE REQUIRED. Where the heater is to be installed in a compartment, permanent air vents are required in VENTILATION the compartment at high and low level.
SECTION 3 INSTALLATION AIR SUPPLY IMPORTANT: 1. The effective area requirements specified in the table are related to the maximum heat VENTILATION input of of the heater(s), and are equivalent to those specified in BS6644 and IGE/UP/10 Pt.1 2. The free area of the grilles should not be less than the size of the recommended ventilation opening.
100 - 150ppm (7 - 10 degrees Clark) and above. This problem can be minimised by reducing the water temperature in the heater and by fitting suitable water pre- treatment equipment. When installing Andrews Water Heaters in hard water areas we would recommend that a water treatment specialist is consulted. Hydrojet System Fig.
SECTION 3 INSTALLATION WATER The water heater must be fed from a cold water feed cistern or static water tank. CONNECTIONS A safety valve must be fitted as specified in BS 6644 Clause 9. VENTED SYSTEMS The safety valve must be fitted either directly to an upper tank tapping or not further than 1 metre along the outlet flow pipe of size not less than the safety valve.

The heater can be used on unvented hot water storage systems, with the addition of an Unvented Systems Kit, part number B228 available from Andrews Water Heaters. See Parts List Page 37. The Wall mounting assembly is available as an optional extra.
INSTALLATION SECTION 3 If higher flow rates are required for the cold water services, a suitable tee fitting should WATER be fitted to the pipework, upstream of item C1. CONNECTIONS The pipework fitted to the tundish outlet should be one size larger than the outlet pipe of the safety device and should be terminated at a suitable drain.
SECTION 4 COMMISSIONING CAUTION! DO NOT OPERATE THE WATER HEATER UNTIL THE STORAGE VESSEL IS COMPLETELY FILLED WITH WATER, WITH WATER RUNNING FROM ALL HOT TAPS. Open the main gas supply cock after all connections to the gas control are completed and test all connections, using proprietary leak detection fluid.
COMMISSIONING SECTION 4 Shutting Off The Burner 1. For long periods only, (7 days or more) move electrical ON/OFF switch to OFF, then turn gas control knob to OFF . Turn off gas service cock. For shorter periods, leave heater under thermostat control. Brown Gas control PV/MV Yellow...
SECTION 4 COMMISSIONING USER'S SAFETY For your safety read before lighting the appliance. GUIDE WARNING 1. Always follow manufacturer's instructions when lighting the appliance. Failure to do so may result in damage to property, personal injury or loss of life. 2.
OPERATION SECTION 5 When properly installed and adjusted, the heater will require minimal attention. Should it become necessary to completely drain the heater, follow instructions given in Section 4, Commissioning. Whenever the heater is filled with cold water, condensation will form on the storage vessel surfaces when the burner is lit.
SECTION 6 SERVICING INTRODUCTION Servicing must be carried out by a properly qualified person. Whilst giving these instructions for the care of the Heater, it is recommended that checks are carried out by the installer or local gas authority, at least annually. Ensure good ventilation by keeping the heater free of extraneous materials and clear of dust and lint.
SERVICING SECTION 6 Annually, remove the main burner rack assembly to clean orifices and related parts of any BURNER dirt or other foreign matter. Inspect the burner ports for obstructions or debris and clean ASSEMBLY with a wire brush, vacuum, or use a mild detergent to clean as necessary. Inspect the pilot.
SECTION 6 SERVICING Check the condition and operation of this component at least once a year to ensure COMBINED it is free from limescale deposits. TEMPERATURE AND PRESSURE Lift the lever at the top of the valve several times until the valve seats properly without leakage and operates freely.
FAULT FINDING SECTION 7 FAULT ACTION WATER DOES (a) Check gas service cock is open. NOT GET HOT (b) Check water valves are open. (c) Check thermostat setting. (reset to higher temperature) HEATER SOOTING, (a) Check gas burner. If possible, check heat input with meter YELLOW FLAME and watch.
