It seems as if there will be a battery involved in running the boiler, as there is a "battery box" and holes in the chassis for wiring. Perhaps we can use some of that available power for lighting.
The kit is now unpacked and laid out roughly where it will be assembled. Well made, but in need of de-burring and softening of sharp edges. One sharp edge had cut through a bag of nuts and bolts which had made a bid for freedom, lurking in the packaging. They were tracked down and re-captured.
It might also be a good idea to thread some chord through the chassis members so that it can be used to pull wiring through at a later stage.
