No. The enchmark Scheme Telford opper and Stainless ylinders is a licensed member of the enchmark Scheme which aims to improve the standard of installation and commissioning of domestic heating and hot water systems in the UK and to encourage regular servicing to optimise safety, efficiency and performance. enchmark places responsibilities on both manufacturers and installers. The purpose is to ensure that customers are provided with the correct equipment for their needs, that it is installed, commissioned and serviced in accordance with the manufacturers instructions by competent persons and that it meets the requirements of the appropriate uilding Regulations. The enchmark hecklist can be used to demonstrate compliance with uilding Regulations and should be provided to the customer for future reference. Installers are required to carry out the installation, commissioning and servicing work in accordance with the enchmark ode of Practice which is available from the Heating and Hotwater Industry ouncil who manage and promote the Scheme.

STP 5 (indirect cylinders only) onnect the boiler flow and return to the labelled connections. efore making the connections ensure that the coil is free from obstructions by blowing through it. The nergy ut Out valve is an essential part of the safety requirements for indirect mains pressure cylinders and should be installed on the primary flow to the cylinder with port (embossed on side of valve body) to the cylinder. The valve will open and close on receiving a signal from the cylinder thermostat. No further control is required for the hot water in a two zone valve system. This valve must also be used in a flow share (Y Plan) system, in conjunction with the midposition valve, to act as a safety cut out valve. The cylinder thermostat controls the temperature of the hot water and also acts as an emergency cut out in the event that the boiler temperature controls fail. The cylinder thermostat is fitted into the pocket labelled Store Temp ontrol in the cylinder, and should be connected to operate the energy cut out valve in accordance with the wiring diagram for the scheme being installed (see pages 11 and 12). We recommend the installation of a 22mm gate valve between the flow connection on the cylinder and the return connection on the cylinder as illustrated in image in step 6 page 5 on & models only.

Subtract the resistance for 4 No. 22mm elbows at 0.8m each = 3.2m Therefore the maximum permitted length equates to: 5.8m. Maximum resistance allowed, expressed as a length of straight pipe (i.e. no elbows or bends) up to 9m up to 18m up to 27m up to 9m up to 18m up to 27m up to 9m up to 18m up to 27m Resistance created by each elbow or bend 0.8m 1.0m 1.4m 1.0m 1.4m 1.7m 1.4m 1.7m 2.3m 5.8m is less than the actual length of 7m therefore calculate the next largest size. Maximum resistance allowed for a straight length of 28mm pipe (2) from G1/2 temperature relief valve equates to: 18m. Subtract the resistance for 4 No. 28mm elbows at 1.0m each = 4m. Therefore the maximum permitted length equates to 14m. s the actual length is 7m, a 28mm (2) copper pipe will be satisfactory. 23 8
NOTS ON WTR QULITY N SLING: SYIT KIT OR TLOR TORNO YLINRS Water hardness can vary considerably around the country. If furring of kettles normally occurs in the area, then the unit should be fed with conditioned water only. This can be provided by a water softener with a high capacity flow rate, or a suitable water conditioner (not supplied). It is recommended that the temperature controls are set below 65 0 to prevent lime scale build up. 1 2 3 IGRM KY The performance of all water storage appliances and their associated components may deteriorate if you do not protect adequately against hard water scaling. If more than 150ppm salts are present in local water samples, an effective conditioner should always be used. X1 X2 X3 1 Inlet Group 2 illing loop 3 Isolating valve to heating MINTNN: X4 4 Isolating valve The following checks should be conducted annually: heck the operation of the T & P valve and xpansion valve by rotating the heads of the valves in turn until water is discharged. The discharge should stop immediately when the valve head is released. Should this not be the case the valve should be replaced. heck that the discharged water flows freely to waste and that there is no blockage. Remove and clean the filter in the Pressure Reducing Valve. 4 5 T&P Relief 6 5 9 6 Pump (Remove if centrel heating boiler has integral pump) 7 ypass heck that the expansion vessel charge pressure is set at 0.2 bar below the incoming pressure. If water is being discharged from the expansion valve it may be indicative of pressure loss within the expansion vessel itself. To check the pressure, isolate the unit from the cold supply and release any pressure by opening a hot tap until water stops flowing. Then use a tyre pressure gauge to verify the charge pressure. If the unit is more than 5 years old when this problem is experienced it may be advisable to replace the pressure vessel. If however, the pressure in the expansion vessel is 0.2 bar below incoming pressure the discharge may be being caused by back pressure or crossover between the cold and hot water supplies see below. To replace the pressure vessel, unscrew from threaded connection. The new pressure vessel should be adjusted to 0.2 bar below incoming pressure and then fitted to the cylinder, ensuring that the threads are sealed appropriately. ack pressure ack pressure from a faulty or uncontrolled mixer valve or appliance will cause the cylinder to over pressurise and may result in water being discharged from the expansion valves. To protect the cylinder we recommend the fitting of a check valve on the hot water draw off to prevent back flow into the cylinder. ll hot water and cold water draw offs should be balanced at the inlet control valve.
