Add prefix “P” for package boiler completely assembled and
wired with jacket and controls (PEG-30-S through PEG-65-S
only).
1.
%'THRU: Add suffix “PID” or “PI” for electronic ignition
(30-65 — damper required in U.S.; optional in Canada); add
“N” for natural; add “L” for propane; add “W” for water; add “S”
for steam; add “T” for tankless heater; add “P” for provisional

3. 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.
4. 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.
Consult local Weil-McLain representative.
