Page 16: Gas System
Introduction 1.6 — Gas System Gas is introduced into the combustion zone through multiple ports in the circular manifold. The full modulation burner's LMV37 controls both the combustion air and fuel metering: it meters the fuel in proportion to fan speed by adjusting the servo-driven gas metering butterfly valve. - Page 17 Introduction The control then powers the ignition electrode and initiates flame. The UV scanner and control confirms flame presence and the burner progresses to main-flame operation. Main flame continues while flame is proven; the external limit switches confirm good operating conditions, and a call for heat exists. During main flame, the LMV37 receives a modulation input signal from a separate modulating controller that directs the LMV37 to provide more or less heat.

Operation circuit. For optimal efficiency, the controller used should be capable of PID load control. The purge rate, ignition position, minimum firing rate, maximum firing rate and fuel-air ratio throughout the firing range is determined by settings made in the Siemens LMV37 display. Refer to the Siemens LMV37 operation manual for further information. - Page 31 Operation Normal automatic operation is detailed in Table 3.1 and the corresponding AZL indications are shown in Fig 3-1.

Page 51: Adjustments
Adjustments CHAPTER 4 4.1 — Overview While each burner is tested at the factory for correct operation before shipment, variable conditions such as burning characteristics of the fuel used and operating load conditions may require further adjustment after installation to assure maximum operating efficiency. Prior to placing the burner and heat exchanger into initial service, a complete inspection should be made of all controls, connecting piping, wiring and all fastenings such as nuts, bolts and setscrews to be sure that no damage or misadjustments occurred during shipping and installation. - Page 52 Adjustments 4.2.3 — Gas Flow The volume of gas is measured in cubic feet as determined by a meter reading. The gas flow rate required depends on the heating value (Btu/cu ft.). The supplying utility can provide this information as well as pressure correction factors.
