The domestic hot water flow rate isautomatically regulated to a maximum:26 = 10.7 l/m (2.4 gpm)33 = 13.4 l/m (2.9 gpm)38 = 15.7 l/m (3.5 gpm)1. Ensure Filling Loop is connected2. Ensure dust cap on auto air vent is slackened off (refer toFrame 66).3. Check all isolation handles on all water connections are inthe open position.4. Open the blue handle on the filling loop, then slowly open theblack handle until pressure gauge reads between 1 to 1.5bar.5. Once pressure gauge dial reads between 1 - 1.5 bar turn thefilling loop isolation valves back to the closed position.6. Disconnect filling loop at the LH side, ensuring top hatwasher is retained and screw on blanking cap.7. Connect extended blanking cap and top hat washer to fillingloop pipe.FILLINgNote. Fully open all DHW taps and ensure water isflowing freely. Once satisfied close all taps.Isolation handlesshown in theclosed positionNOTEs.Ensure all boss blanking plugs are removed before connecting hardware. Eachvalve must be fitted to the correct boss as shown in the picture.Ensure each union is fitted with fibre seals provided.Do not subject any of the isolating valves to heat as the seals may be damaged.Note that all isolation handlesare shown in the open postion.WaTER CONNECTIONs Ch1. Connect the CH flow service valve (black handle) andcopper tail provided in the hardware pack to the threadedboss connection provided at the lower rear of the boiler.2. Connect the CH rtn. valve (black handle) and copper tail.3. If connecting the boiler to heating loads in excess of60,000 Btu/h, connecting flow and return heating systemspipework must be sized in 28mm diameter at the pointof pipe connection to the boiler tails. use 22mm x 28mmpipe adaptors as appropriate.gas CONNECTIONIMpORTaNT. The gas service cock is sealed with a non-metallicblue fibre washer, which must not be overheated when makingcapillary connections. Refer to Frame 1 for details of the positionof the gas connection.For additional gas supply info refer to “Gas Supply” on page 8.saFETy VaLVE DRaINThe safety valve connection, located at the bottom right-handside of the boiler, comprises a 15mm diameter stub pipe.The discharge pipe should be positioned so that the dischargeof water or steam cannot create a hazard to the occupants ofthe premises or damage the electrical components and wiring.WaTER CONNECTIONs DhW1. Fit the DHW inlet service valve (blue handle) and copper tailto the threaded boss connection ensuring the seal providedis correctly located.2.
