Hey can anyone tell me where I should take an SSE test on a LAARS Endurance EBP 110 boiler?  I could not find anything on the specs. Thanks a bunch

    There is a small

    plug in the 3" flue inside the unit, that is the place to take a combustion test.It can also be taken at the exhaust terminal outside.

    For natural gas you should get 9.0 to 9.6 % CO2 and for LP 9.7 to 10.1 % CO2.the Offset for both LP and Natural is -0.08 inches W.C.
