Check that the appliance is suitable for the gas supply; refer to data labels on packaging and/or the fire for gas type. Note: Natural gas and Propane (LPG) models are not interchangeable. The gas installation must be in accordance with the current issue of BS6891.Gas supply pressure at the fire should be 20mbar for natural gas. The gas supply should be connected with the 1/4"BSP nut and olive with 8mm tubing. A maximum pipe run of 1.5 meters (or 5 feet) should be adhered to and copper tubing may be used provided a distance of 25mm is maintained between pipe-work and any surface of the fire. A gas service cock should be fitted adjacent to the fireplace to enable safe removal of the appliance for servicing. After fitting the supply, operate the gas cock (supplied) and check all joints up to the termination of the supply pipe for gas tightness using a soap/water solution and the pressure drop method. To check the pressure to the burner it is necessary to ignite the appliance and set to 'high rate'. This is carried out by following instructions on pages 9 and 10. Cold setting pressures are in the Technical data section on page 6. The pressure test point is located through the hole in the valve bracket marked 'test point', See Fig.8 below. Pressure test point Fig. 8 TEST SEQUENCE ENSURE FIRE IS OFF 1. Open control door. 2. Loosen test point screw. 3. Connect hose of test equipment to test point through the test point hole in bracket. (If necessary open fire door and remove coal set, base matrix plate and heatsheild. Close door on completion) 4. Turn on fire and set flame on high. 5. Take reading. 6. Turn fire off. 7. Remove test equipment hose. 8. Re-tighten test screw (If necessary replace heatsheild, matrix plate and coal set.

Step 2 Turn the appliance off to extinguish the pilot, listen for a snap at the control valve. This should occur within 60 seconds of the pilot flame being extinguished. The snap sound will be the magnet disengaging, and thus shutting off the flow of gas to the pilot and burner. Spillage Test A qualified gas engineer should Perform a spillage test as follows: Step 1. Close all doors and windows. Step 2 Light the appliance and set to the high rate. Step 3. Allow fire to warm up for 10 minutes. Step 4. Position the smoke match at the back of the fire centrally beneath the draught diverter as shown in Fig 9. All of the smoke should be drawn into the fire. If this does not occur the appliance must be disconnected and the flue checked. Step 5. If there is an extractor fan in any room, this must be turned on and any doors between it and the fire left open, repeat the spillage test. Repeated operation of the spillage monitoring system indicates that there maybe a flue draw problem. In this situation no more attempts at operating the appliance should take place and your gas engineer should be contacted. Warning: The spillage monitoring system is a safety feature required by law and must not be adjusted or put out of action by the installer. If the spillage monitoring system or any of its parts are to be replaced, only original manufacturers parts are to be used. Fig. 9 Note: The fire will give off non-toxic fumes when first used. This is perfectly normal and is due to the paint curing, it will disappear after the first few hours. Once the spillage test is complete open windows and doors to ventilate the area.
