Gas piping question

[felixking]

Just installed a furnace, ran short of a coupling, I had to use a gavalnized coupling on black iron pipe, will this cause any problem or against any code, checked gas code (Ontario), didn't find any info about mixing gavalnized iron pipe with black iron pipe.

Any suggestion ?

Thank in advance

So why did You have to use galvanized?

Galvanized is not rated for gas. You have to go with black pipe, flexible stainless steel or brass (valves).

just 1` coupling should not be a problem

It would be against code here in Nebraska. Call your code people and find out if its OK there.

Galvanizing could flake off and affect the gas valve. If possible, go back and replace with a black iron fitting. Odds are, there probably won't be any effect. Just cover your a**.

gas company in our area uses galvanized on the pipes they use between our black iron stub out and the meter.........
