INSTALLER GUIDEPage 254. Remove the convection box. Drill four holes in the fireplace front surround at themarked positions using a suitably sized masonry drill for the fibre / wooden plugssupplied.5. Insert a fibre / wooden plug into each hole.6. Place the convection box back in position in the fireplace.7. Fit a woodscrew through each hole in the convection box flanges and tighten toseal the box to the fireplace surround.9.2 Method 2 - Cable retention and floor fixing.1. Make sure that the relevant areas at the fireplace back or floor are sound enoughto take the eyebolts and screws.If these areas have deteriorateddue to prolonged use theyshould be made sound withsuitable cement.2. Drill four holes in the rear wallof the fireplace for the eyeboltplugs. The holes should bedrilled within the range ofpositions shown in figure 19using a suitably sized masonrydrill for the fibre / wooden plugssupplied. The holes should beequidistant each side of thecentre line of the fireplace to ensure that the appliance finishes centrally in theopening when tension is applied to the cables.3. Insert a fibre / wooden plug into each hole. Use the fibre / wooden plugs suppliedwith this appliance - Never use plastic plugs instead of the fibre / wooden plugssupplied. Screw the eyebolts into the plugs. Make sure that the bolts are secure.4. Place the convection box unit close to the fireplace but allow sufficient access intothe fireplace opening so that the cables can be threaded through the eyebolts andreturned through the back of the convection box. If a concealed connection is beingused, insert the convection box into the fireplacefeeding the supply pipe through the pierced hole in therear grommet.5. The convection box has two holes at each side ofthe convected air opening. Insert one end of eachcable (one cable each side) from the back through thelower of the two holes and return the end through theupper of the holes (See figure 20). Give the cables apull so that they grip against the convection boxflanges.© Baxi Heating U.K. Limited 2009.Figure 20. Upper cableretentionFigure 19. Eyebolt positions
