Page 16: Heating And Hot Water System Design
HEATING SYSTEM DESIGN The Jaguar is compatible with any type of sealed system installation, i.e. radiators, fan convectors etc. Pipe sectional areas shall be determined in accordance with normal practices, using the pump curve, refer to ‘Technical Data’. The distribution system shall be calculated in accordance with the output requirements of the actual system, not the maximum output of the boiler. - Page 17 Safety valve discharge WARNING: It must not discharge above an entrance or window or any type of public access area. Connect the safety valve discharge pipe to the valve, the discharge must be extend- ed using not less than 15 mm o.d. pipe, to discharge in a visible position outside the building, facing downward, preferably over a drain.

Page 19: Boiler Installation
BOILER INSTALLATION To install the boiler, proceed as follows: • Allowing sufficient clearances for servicing/repair, place the template on the wall (see diagram 7). Note: The boiler can be installed only on the closed wall. • Determine the position of the flue hole and drill hole for flue, preferably using a 120 mm core drill. - Page 20 • Fit gasket (E) onto underside of flue elbow (D). • Carefully insert ‘O’ ring (J) into upper and lower parts of inner elbow. • Place spacer (K) (supplied with boiler) onto top of boiler Jaguar 23 only (see dia- gram 9).

Page 24: Electrical Connection
ELECTRICAL CONNECTION Warning: This boiler must be earthed. All system components must be of an approved type. Connection of the whole electrical system and any heating system controls to the electri- cal supply must be through a common isolator. Isolation should preferably be by a double pole switched fuse spur box having a mini- mum contact separation of 3 mm on each pole. -
Page 25: Commissioning
COMMISSIONING The commissioning and first firing of the boiler must only be carried out by a competent person. To gain access to the inside of the boiler undo screw securing front panel at the boiler bottom, remove front panel by pulling forwards, lifting it up and off. Note – upper edge of front casing is fixed to the boiler by means of 2 pins. - Page 26 • Restart boiler and operate until a maximum temperature is reached. Shut down boiler and vent air from heating system. If necessary, top up heating system and make sure that a pressure at least of 1 bar is indicated on the display when system is COLD. Gas installation It is recommended that any air is purged from the supply at the gas inlet test point on the gas valve, see diagram 13.
- Page 27 Safety devices Air flow rate safety device If an obstruction, even partial, of the flue occurs, the built in safety system of the boiler will turn the boiler OFF. The boiler will be ready to operate when the fault has been cleared.

Page 28: Servicing Instructions
SERVICING INSTRUCTIONS To ensure the continued efficient and safe operation of the boiler, it is recommended that it is checked and serviced at regular intervals. The frequency of servicing will depend upon the installation conditions and usage but, in general, once a year should be enough. It is the law that any servicing is carried out by a competent person. -
