16.Adjust air shutter on the burner. The air shutter is located on the bottom of the burner on the left. (Fig. 46) Loosen the two nuts holding the shutter in place. On natural gas units, the shutter is shipped fully closed. To convert to LP, reset the shutter as speci- fied in Table 2. (Fig. 34) On propane unit the shutter is set at 1/8” or 3/8” opening depending on rating plate serial number. To convert to natural gas, the shutter should set to fully closed. Refasten the two nuts.

Fig. 35 Remove and replace injector orifices.

NOTE: Be sure burner leg remains at a 90° angle to firebox base after conversion.

17.Replace burner. Slide the burner in at an angle with left side lower than the right side. Slide the left side onto the injectors, making sure the burner leg remains at a 90° angle to the base. Lower the right hand side down in to place. Make sure the burner is as far left as possible and the injector shoulders are inside the burner.

NOTE: It is very critical to keep the left burner leg, which holds the injectors, at a 90° angel to the base. (Fig. 35) This keeps the orifices aligned with the tubes inside burner. Failure to do so could affect the flame appearance and performance of the unit.

18.Place conversion label on valve.

19.Reinstall the right and left log bracket assembly.

20.Replace logs.

21.Replace glass and stove front.

22.Check manifold pressure.

Conversion is complete.

On the other hand, the CFM 2467 engine has been engineered with a focus on reducing noise pollution and emissions. This engine incorporates cutting-edge noise-reducing technologies, including a redesigned inlet and an innovative exhaust system that reduces noise levels significantly during operation. This makes the 2467 an ideal solution for airports in urban areas where noise regulations are stringent. Furthermore, the engine's environmentally friendly design complies with the latest emissions standards, which is increasingly important in today's aviation market.

Both engines utilize advanced digital technologies, including the latest in engine health monitoring systems. These systems provide real-time data analytics to operators, allowing for predictive maintenance and minimizing downtime. This technological integration not only enhances operational efficiency but also helps in extending the lifespan of the engines.

In terms of operational characteristics, both the CFM 2468 and 2467 engines are built to perform under a wide range of conditions. Their robust design ensures they can withstand various environmental challenges, from extreme temperatures to high humidity. Additionally, their modular design simplifies maintenance procedures, allowing for quicker turnaround times.

In summary, the CFM Corporation 2468 and 2467 engines exemplify the company's commitment to innovation, efficiency, and sustainability. With their advanced technologies and impressive features, these engines are set to redefine performance standards in the aviation industry, making them a preferred choice for airlines globally.
