Notes:

1.As an Energy Star Partner, Lochinvar has determined that Knight wall mount boilers meet the Energy Star guidelines for energy efficiency.

2.The ratings are 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 of 1.15.

4.Knight wall mount boilers require special gas venting. Use only the vent materials and methods specified in the Knight Wall Mount Installation and Operation Manual.

5.Standard Knight wall mount boilers are equipped to operate from sea level to 4,500 feet only with no adjustments. The boiler will de-rate by 4% for each 1,000 feet above sea level up to 4,500 feet.

6.High altitude Knight wall mount boilers are equipped to operate from 3,000 to 12,000 feet only with no field adjustments. The boiler will de-rate by 2% for each 1,000 feet above 3,000 feet. High altitude models are manufactured with a different control module for altitude operation, but the operation given in this manual remains the same as the standard boilers. A high altitude label (as shown in FIG. A) is also affixed to the unit.

7.The Knight Wall Mount boiler input rate, on some models, is reduced for vent lengths beyond the minimum. Models WB(N,L)081 and WB(N,L)106 with 2" vent will reduce 1% for every 10 feet of vent. Models WB(N,L)151 and WB(N,L)211 with 3" vent will reduce 0.5% for every 10 feet of vent.

8.Ratings have been confirmed by the Hydronics Institute, Section of AHRI.

9.Knight wall mount boilers comply with the requirements of CSD-1 Section CW-400 requirements as a temperature operation control. The manual reset high limit provided with the Knight is listed to UL353.
