Notes
1. Based on standard test procedures prescribed by the United States Department of Energy.
2. Net I=B=R 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 pickup. Ratings are based on a piping and pickup allowance of 1.15. An
additional allowance should be made for unusual piping and pickup loads.
3. Direct exhaust CGt boilers require special venting, consistent with Category III boilers. Use only the vent materials and
methods specified in this manual. Chimney draft vented CGt boilers may use type B vent or other materials suitable for
venting Category I boilers.
CGt boilers for residential radiant panel systems, converted gravity heating systems or other low water temperature
applications should be installed with balancing valves and bypass piping equal to the supply and return size to
avoid excessive flue gas condensation due to lower operating water temperatures. For alternate piping, contact
your Weil-McLain sales office. CSA design certified for installation on combustible flooring. Tested for 50 psi
working pressure.
