Page 19: Choice Of The Location
5.5 Choice of the Location 5.5.2 Ventilation 5.5.1 Location of the boiler Where the appliance is installed in a cupboard or compartment, Locate the boiler in an area where leakage from the boiler no air vents are required. Local Codes refer to room sealed or connections will not result in damage to the area adjacent appliances installed in compartments. The appliance will run to the boiler or to the lower floor of the structure. When such sufficiently cool without ventilation. locations cannot be avoided, it is required that a suitable drain pan, adequately drained, be installed under the boiler. Examples are shown of the following methods of termination: ▪ The boiler may be fitted to any suitable wall with the flue ▪ to an internal soil & vent pipe passing through an outside wall or roof and discharging to ▪ via an internal discharge branch (e.g. sink waste) atmosphere in a position permitting satisfactory removal of downstream of the trap combustion products and providing an adequate air supply. ▪ to a drain or gully ▪ The boiler should be fitted within the building unless ▪ to a purpose made soak away otherwise protected by a suitable enclosure i.e. garage or ▪ pumped into an internal discharge branch (e.g. sink waste) outhouse. (The boiler may be fitted inside of cupboard.) downstream of the trap pumped into an external soil & vent pipe. ▪ to a drain or gully with extended external run & trace heating. 5.5.3 Available Pump Head K1 boilers are supplied with built-in circulating pump. The available head to the system are showed in the following diagrams. - Pump Performance Curve ▪ Where the boiler is sited in an unheated enclosure and during periods when the heating system is to be unused it is recommended that the permanent live is left on to give BOILER frost protection. -
Page 20: Condensate Drain
5.5.4 Condensate Drain The boiler condensate trap included a seal, therefore it is unnecessary to install an air break and trap in the discharge pipework. ▪ The condensate outlet will accept 21.5mm(3/4") plastic overflow pipe. It is highly recommended that this discharge internally into the household drainage system. Where this is not possible providing every possible precaution is taken Minimum Ø21.5mm Be less than 3M to prevent freezing. ▪ Ensure the discharge of condensate complies with any national or local regulations in force. ▪ The discharge pipe should be run in a proprietary drain pipe material e.g. PVC, PVC-U, ABS, PVC-C or PP. ▪ If the boiler is fitted in an unheated location the entire condensate discharge pipe should be treated as an external run and sized and insulated accordingly. ▪ In all cases discharge pipe must be installed to aid disposal of the condensate. To reduce the risk of condensate being trapped, as few bends and fittings as possible should be used and any burrs on cut pipe removed. ▪ When discharging condensate into a soil stack or waste pipe the effects of existing plumbing must be considered. If soil pipes or waste are subjected to internal pressure fluctuations when WC’s are flushed or sinks emptied then backpressure may force water out of the boiler trap and cause appliance lockout. ▪ A boiler discharge pump is available which will dispose of both condensate and high temperature water from the relief valve. It has a maximum head of 5 meters. Follow the instructions supplied with the pump. ▪ Condensate Drain Pipe ‘Trace Heating’ elements are available in various lengths, 1, 2, 3 & 5 meters. Where the drain is between 3 & 5 meters a 5 meters kit can be used and ‘double back’ upon itself. ▪ It is possible to fit the element externally on the condensate drain or internally as detailed in the instructions provided. ▪ The fitting of a ‘Trace Heating’ element is not a substitute for correct installation of the condensate drain. All requirements ▪ Metal pipework is not suitable for use in condensate in this section must still be adhered to. - Page 21 Some examples of the type of condensate terminations can be found below. ▪ Termination to a purpose made soakaway. ▪ Termination to an internal soil and vent pipe Sink 55mm per meter of pipe run 2.5' minimum fall Pipe must terminate above water level but below surrounding surface. *450mm is applicable up to 3 stories.

Page 22: Minimum Clearances
5.5.6 Flue Terminal Position 5.5.5 Minimum Clearances The minimum acceptable clearances are shown below; ▪ A flat vertical area is required for the installation of the boiler. ▪ Minimum clearances must be maintained. ▪ If fitting the boiler into an airing cupboard use a non-combustible material to separate the boiler from the airing space. ▪ These dimensions include the necessary clearances around the boiler for case removal, spanner access and air movement. Additional clearances may be required for the passage of pipes around local obstructions such as joists running parallel to the front face of the boiler. ▪ This is minimum recommended dimension. Greater clearance will help installation and maintenance. - Legend of Flue Location CAUTION All measurements are the minimum clearances required.

6. Remove the existing Natural Gas orifice. Save the packing 7.3 GasConversion for re-use. 7.3.1 Natural Gas to Propane Conversion ■ The K1 condensing gas boiler is configured for Natural Gas (NG) from the factory. ■ If your gas supply is Propane Gas (LP), your boiler can be Nozzle converted to burn propane gas as follows: Packing 1. Turn OFF the Boiler. The ON / OFF button is located at the bottom left of the Control Display. 2. Turn OFF the GAS and WATER supply to the Boiler. (valves are located on the plumbing pipes.) 3. Using a Phillips screwdriver, remove the 4 screws on the front cover. 4. Locate the Gas Inlet Pipe at the top left of the unit as is shown in Figure below, and loosen the Brass Fittings at both ends of the Gas Inlet Pipe. 7. Replace the old Orifice with the new Orifice for LP (propane) gas. Re-use the packing from previous. 8. Return the Gas Inlet Pipe to its original position and tighten both of the Brass Fittings. 9. Set the main controller Dip Switch to change the gas type. Dip Switch Switch Position Power (Kcal) 16,000 20,000 25,000 30,000 5. Completely un-thread the Brass Fitting on the right, and then carefully swing the Gas Inlet Pipe downward just enough so that Table1 it is out of the way. Switch Position Power (Kcal) Table2 10. Turn ON the GAS and WATER supply to the Boiler. -
