Close all the doors and windows in the room and after the fire has been alight for five minutes insert a lighted smoke match in line with the bottom edge of the canopy and 10mm below it (See Fig. 8). Hold the match with a pair of pliers or in a metal tube. If all of the smoke is drawn into the fire the installation is satisfactory. if in doubt, repeat the test after a further ten minutes.
If there is a fan or a fan operated appliance in a connecting room then the spillage test must be repeated with the fan running and all
If spillage is detected, inspect the sealing of the fire to the surround / hearth. If this is satisfactory proceed as follows:
If a spigot restrictor was fitted, disconnect the fire and remove the spigot restrictor.
