EXPLANATORY NOTES

--All boilers are design certified for installation on noncombustible floor. --For installation on combustible floors use combustible floor kit.

--Recommended chimney height 20 feet. In special cases where conditions permit, chimney height may be reduced to 10 feet. Refer to the latest revision of NFGC part 11.

--Electric service to be 120 Volts, 15 Amps, 60 Hz.

--The MEA number for the MGB series boiler is 19-79 Vol. II

§For elevations above 2000 feet, ratings should be reduced at a rate of 4% for each 1000 feet above sea level.

∆Tank sized for non-ferrous baseboard or radiant panel systems. Increase size for cast iron baseboard and radiation.

†Base on 170' temperature in radiators.

--Net I=B=R ratings include 15% allowance for normal piping and pick-up load. Manufacturer should be consulted on installations having otherthan normal piping and pick-up requirements.

**For equivalent square feet of radiation, divide I=B=R output by 150.
