Remove carton.2. Study the Burner position and the Boiler wall position and decide on the best oilpipe configuration, see Section 5-2.5 and Section 7.3. Remove pull-off front panel, top panel and Control Panel.Unscrew and remove side panels and bottom panel.4. Remove access door and lift out all baffles from heat exchanger.5. Remove Boiler body from wood transport blocks - 3 screws, 1 top, 2 bottom.6. Offer back panel to the position required on the wall and use this as a template tomark the drilling positions for the 3 mounting rawl bolts ‘R’.Also mark the positions of any holes required through wall for oil pipes, fire checkvalve and electric cable.7. Remove panel and accurately drill required holes and fit 3 rawl bolts into holes ‘R’.8. Remove required knockouts ‘K’ from back panel.For top entry flues ignorFor top entry flues ignorFor top entry flues ignorFor top entry flues ignorFor top entry flues ignore steps 9 to 16 and move onto 17.e steps 9 to 16 and move onto 17.e steps 9 to 16 and move onto 17.e steps 9 to 16 and move onto 17.e steps 9 to 16 and move onto 17.BALANCED FLUE (Rear) MODELS ONLYRefer to Instruction Sheet supplied in flue kit.9. Hang back panel onto rawl bolts and mark position for balanced flue.10. Remove panel and, using a core drill, cut a NEAT hole through the wall for the flue.11. Fit back panel onto the 3 rawl bolts - do not fit nuts.12. Check that the hole drilled is in the middle of the square cut-out of the panel andthat the flue terminal passes through the hole.13. Clear work space and carefully lift the Boiler heat exchanger onto the 3 rawl bolts, fitnuts (the long nut is for the top bolt). Tighten nuts sufficiently to set rawl bolts inthe wall.14. Assemble the flue as per instructions supplied with the flue kit.15. Pass the flue through the drilled hole and connect it to the Boiler with the gasket.16. Adjust the Boiler for level and tighten the 3 rawl bolt nuts.TOP FLUE MODELS ONLY17.
