Arcoleader Boiler A 1 4 P

Tracie

I have a general question about my old Arcoleader Boiler number A1 4P series 18 J1.  I looked in the firebox and I see firebrick at the back of it, and some at the bottom.  The question is, is the entire interior of the firebox supposed to be lined with the firebrick?  This is my first ever cold weather since moving into the house, and I don't have a manual for the thing, so any advice would be appreciated.  I really need to fire her up soon, but am hesitant until I find out if it is safe.

wet base

It would have had some on the sides, but it is a wet base cast iron boiler, and only needs a target wall at best. Most important is whether there is an extra layer of brick laying on the bottom for the flame to impinge on, or was it removed. Have it checked before you start using it, just in case.
