but not exceeding 25 mm. inside diameter; maximum length of dead leg 7.5 metres; - for pipes with an inside diameter exceeding 25 mm. maximum dead leg 3.0 metres. 1) Gas cock 2) Stop valve 3) Three way vent valve 4) T&P valve 5) Non-return valve 6) Circulation pump 7) Drain valve A) Gas supply B) Hot Water C) Cold Water D) Overflow E. Return circulatio. Diagram 5 - Typical UK vented system Depending on the length and insulation of the water piping and the water demand frequency, it may be necessary to install a circulation system on the drain cock. The return pipe of the circulation piping can be fitted on the top of the drain cock after the sealing plug has been removed (see figure 6). Unvented To install an A.O. Smith water heater on an unvented cold water supply system a kit of valves and fittings listed by the water research centre and complying with part G3 of the current building regulations and BS 7206 should be used. Installation should be carried out generally as shown on diagram 7. Kits are available from A.O. Smith or our distributors. 1) Gas cock 2) Stop valve 3) Expansion vessel 4) T&P valve Figure 6 5) Non-return valve 6) Circulation pump 7) Drain valve 8) Pressure limiting valve 9) Expansion valve A) Gas supply B) Hot water C) Cold water D) Hot water supply E) Return circulation IMD-0066-R0 Diagram 7 - Connection diagram (unvented system) Depending on the water demand pattern (e.g., small amounts frequently), it may be necessary to circulate the water in the water heater to prevent temperature stratification. Therefore, we recommend that a circulation system is installed in the event of such demand patterns (see figure 8). Kits are available from A.O. Smith or our distributors. 1) Pump (type: Grundfos UP 20-15 N150, or similar) 2) Non-return valve 3) Gate valve 4) Drain valve 5) Gas valve A) Cold Water B) Hot Water C) Return circulation pipe D) Gas supply IMD-0059 Figure 8 - Connection diagram including destratification circulation system 2.1.3 Condensation drain In order to guarantee the correct operation of the water heater, the condensate drain of the water heater must open into the sewer interrupted, provided with an extra stench trap or siphon. A condensation drain section fixed to the water heater should be fitted under the slope. The condensate drain of the water heater must never be sealed. 2.1.4 Gas connection The gas installation may only be carried out by a registered installer and in accordance with the relevant local authority and building regulations and followint British standards. 2.1.5 Flue connections (concentric) The combined flue discharge and air intake tubes (concentric) should always be assembled with a rising slope towards the flue terminal, and in accordance with the table below. IMD-0060 figure 9 -Wall configuration (see figure 9) Type: M2000 MDV SE Manufacturer: Meulink & Grol Pipe material flue tube: Thick-walled aluminium with lip ring seal.

These will each equate to 1 metre of flue length. The following applies for the horizontal pipe: slope of at least 5 mm per metre of pipe to the water heater. The maximum flue configuration is therefore 7000 mm A maximum of 2 bends (45° or 90°) may be used with pipe, 2 bends (45°/90°) and a lead-through set. IMD-0061 IMD-0062 Figure 10 and 11 - Roof discharge. 2.1.6 Electrical connection All electrical connections must be carried out by a registered electrical contractor to the relevant regulations. The BFM must be connected to a supply voltage by means of a permanent electric connection and have a feeder cable not less than 3 x 1,0 mm.. Supply voltage Supply network frequency Minimum fuse required 220/240 VAC 50 Hz 1 A The electrical diagram of the BFM-heater and the connections in the control-column are shown in figures 12 and...
