I need to remove an old broken Rayburn Supreme Multifuel cooker/water heater in preparation for installing a new multifuel stove. Can anyone give me any tips on the best approach? I've disconnected the pipes and taken out all the obvious and easily removable bits--riddler, flue box, hot plate, oven lining, doors, etc. But I'd like to reduce the weight to a minimum before trying to get the thing out of the door. Looks like it might be possible to take the top and sides off, but the slotted bolts (under the chrome caps) that secure the top seem pretty well rusted in, and I don't know if there's anything else holding it in place.
Would be very grateful for advice from anyone who's had experience of stripping/removing Rayburns (or who knows how they're put together!).
