2. EGH water boilers tested for 50 P.S.I working pressure.
3. Based on standard test procedures prescribed by the United
States Department of Energy.
EG-75 thru EGH-125: CSA Gross output.
4. EGH-105 thru 125 may be installed at altitudes of 2,000-4,500
feet subject to acceptance by Provincial Inspections Authority
based on field tests of individual installations.
5. Net AHRI ratings are based on net installed radiation of
sufficient quantity for the requirements of the building and
nothing need be added for normal piping and pick-up. Water
ratingsarebasedonapipingandpick-upallowanceof1.15;
steam ratings on an allowance of 1.333. An additional allow-
ance should be made for unusual piping and pick-up loads.
