I have just started using an old antique coal stove in our kitchen- a Bungalow 118 manufactured by the Birmingham Stove and Range Company. I am cleaning it out today and notice that there appears to be some "cement" or mortar missing from some of the spaces between the iron plates that are connected inside the stove. How crucial is this mortar to safe operation of the stove? If so, what type of material do I use to replace the missing "cement"?
Background: I have had successful burns day and night with the stove for the past 5 days thanks to the info on this forum provided by Devil 505 on firelighting, shaking, and raking. The missing "cement" doesn't seem to cause any problems with the fire. I am also applying stove polish today to get the unit spruced up for the holidays before I refire.
