I know that there is not much space around the burner for your oil pipes, especially if you are double piped BUT come through the cab and go vertical, dont try to squeeze them around the burner and FFS, please bend the pipes, dont use hundreds of compression fittings, they WILL LEAK (because as if you do it like that, you are not the sort to use inserts either).
