what does IRC mean

I have a copy of the Rocket Mass Heater Builders Guide.
On page 64 in a drawing it has the inscription ' $ " gap to combustibles [ IRC]
I cannot work out what IRC means.
can anybody help?

Hiya John!

I have so many books to read! I haven't yet gotten around to reading my copy of the Rocket Mass Heater Builder's Guide (it's on my list to get to). I looked up the page you're refering to and found teh diagram you were talking about. I found a discussion on Rocket Mass Heaters vs. Scandinavian/Slavic Masonry Heaters where they discuss the two types of designs.

In their discussion, Eric Moshier quotes Samantax Antone who wrote:

Another bonus is that a masonry heater is listed in the IRC so you can legally build them and your insurance company will cover them.
A smaller masonry heater for heating ~1,000s.f. normally only needs 200 firebrick.

After a little more digging, I found that IRC refers to the International Residential Code.

As I have not gotten to reading the Rocket Mass Heater Builder's Guide in its entirety yet, I do not fully know the context that IRC is being used, but I think this is a reasonable guess as to what it means.

International Residential Code

I think in this case, it's international residential code.

when i write it, often it's "if i recall correctly" Forgetting the two ii just putting just one in front of the RC. Sorry!

Thanks for clarifying Samatax!

Thanks, I find it annoying when acronyms are used with out a glossary of terms within the book.

I think it's always been the 'proper' practice to write it out fully the first time and then go on to use the acronym in the rest of the text.  

I've been frustrated also trying to go back in an article or essay or permies message and never find the full name that the acronym is representing.
