INSTALLATION INSTRUCTIONS
(continued)
• An AGA approved 150mm diameter Gas Cowl must be fitted.
• The flue or chimney of an open gas fire must be kept clear at all times. Devices which close or
temporally close the flue or chimney are not permitted. (e.g. a damper must be removed or
securely disabled in the fully open position.)
• If these conditions are met the chimney should usually provide satisfactory draw. In any event,
the chimney and final installation must be tested for spillage into the room. This can be done by
lighting a paper fire in the fireplace (before the appliance is installed) and holding a smoking
twist of paper or a smoking match by the front of the fireplace. Air conditioning vents near the
fireplace may also cause spillage.
• The fireplace must be at least 470mm wide (front), 325mm wide (rear) x 250mm Deep x
400mm high to suit the Type 1 burner.
• The room must have total fixed ventilation equal to the chimney / flue area.
• Refer also to “Wonderfire FFB Convector Box” instructions if fitting a Convector Box.
Fitting the unit
• The unit should be fixed to the base of the fireplace with a screw to each front corner of the
burner.
Gas
• Gas connection is to a ½” BSP male fitting connected to the RHS of the valve. It is located
100mm from front, 45mm up from floor and 170mm in from front RH corner of the appliance
• Thoroughly blow out the supply pipe to clear any dust and debris.
• Ensure all connections are gas tight.
• Note: Do not bring the gas supply down the active chimney.
Coals
The WONDERFIRE has ceramic coals and a burner designed to appear like a coal fire.
• The unit is supplied with the ceramics assembled ready for operation.
• When the unit is unpacked check that no damage has occurred in transport.
• Carefully place the ceramic coal assembly on top of the burner making sure that it sits in place
correctly.
• No other coals should be added as this will adversely affect the performance of the fire.
• Wash hands after handling the ceramic base or coal assembly.
Commissioning
• Once the fire is fitted and connected to the gas, test the unit’s operation.
• After 10 minutes operation from cold, test for fireplace spillage, i.e. all products of combustion
are entering the flue, by traversing the perimeter of the opening or canopy, using a smoke
generator (E.g. a smoking twist of paper or smoke match).
