|
| 2. Based on standard test procedures prescribed by the United States Department of Energy. |

| |||||||||
Notes |
| 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 | ||||||||||
|
| of 1.15. An additional allowance should be made for unusual piping and pickup loads. |
|
| |||||||
|
|
| |||||||||
|
| 4. CGi boilers require special venting, consistent with Category I or III boiler. Use only the vent materials and | |||||||||
|
| methods specified in this manual. Vent diameter shown above is for direct exhaust venting. See Table 3, | |||||||||
|
| page 14, for vent diameter when chimney draft venting. |

CGi 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.
