hello all , this is my first post so please be gentle! I have a dovre 2000 from year 2003 and I have managed to get a boiler to suit it without instructions, anyways my question is this ,when I fit the boiler into position at the rear of the chamber should I leave a space berhind the boiler unit to the back of the fire chamber or should I butt it up against the rear, I was thinking if i offset it an inch or so that it would give me more surface area to heat ?
