Blower motor service factors greater than 1. may be required when firing into negative chamber pressure applications. For specific application questions, contact Eclipse. 3 For proper performance, this pressure must be kept constant across the burner operating range. See Design Guide 111 for more information about typical fuel composition and properties. All weights are approximate. All inputs based upon gross calorific values and standard conditions: 1 atmosphere, 7 F (1 C). Blower motor service factors greater than 1. may be required when firing into negative chamber pressure applications. For specific application questions, contact Eclipse. Eclipse reserves the right to change the construction and/or configuration of our products at any time without being obliged to adjust earlier supplies accordingly. All information is based on laboratory testing in neutral (." w.c.) chamber with standard combustor design. Different chamber conditions may affect the data.
