Based on standard test procedures prescribed by the United States Department of Energy.

 

 

 

 

 

 

 

 

 

 

 

 

 

3.

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

Notes

 

of 1.15. An additional allowance should be made for unusual piping and pickup loads.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

4.

CGs boilers require special venting, consistent with Category III or IV boiler. Use only the vent materials and

 

 

methods specified in CGs vent supplements. CGs boilers may be direct-vented (using 3” diameter air piping)

 

 

as specified in the direct vent supplements.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

5.

As an Energy Star Partner, Weil-McLain has determined that the CGs-3 meets the Energy Star guidelines for

 

 

energy efficiency.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

CGs boilers for residential radiant panel systems, converted gravity heating systems or other low water tempera- ture 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.
