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.
