Installation Instructions

GAS REQUIREMENTS

WARNING

•Installation must conform to local codes and ordinances, or in their absence, the

NATIONAL FUEL GAS CODE, ANSI Z223.

•This gas dryer is equipped with a Valve and Burner Assembly for use only with natural gas. Using conversion kit 14-A048, your local service organization can convert this dryer for use with propane (LP) gas. ALL CONVERSIONS MUST BE MADE BY PROPERLY TRAINED AND QUALIFIED PERSONNEL AND IN ACCORDANCE WITH LOCAL CODES AND ORDINANCE REQUIREMENTS.

•The dryer must be disconnected from the gas supply piping system during any pressure testing of that system at a test pressure in excess of 0.5 PSI (3.4 KPa).

•The dryer must be isolated from the gas supply piping system by closing the equipment shut-off valve during any pressure testing of the gas supply piping of test pressure equal to or less than 0.5 PSI (3.4KPa).

DRYER GAS SUPPLY CONNECTION

2″

 

(5.1 cm)

 

25⁄8″ (6.7 cm)

3/8″ NPT MALE THREAD GAS SUPPLY

NOTE: Add to vertical dimension the distance between cabinet bottom to floor.

GAS SUPPLY

•A 1/8″ National Pipe Taper thread plugged tapping, accessible for test gauge connection, must be installed immediately upstream of the gas supply connection to the dryer. Contact your local gas utility should you have questions on the installation of the plugged tapping.

•Supply line is to be 1/2″ rigid pipe and equipped with an accessible shutoff within 6 feet of, and in the same room with, the dryer.

•Use pipe thread compound appropriate for natural or LP gas or use Teflon® tape.

•Connect flexible metal connector to dryer and gas supply.

IN THE COMMONWEALTH

OF MASSACHUSETTS

•This product must be installed by a licensed plumber or gas fitter.

•When using ball-type gas shut-off valves, they shall be the T-handle type.

•A flexible gas connector, when used, must not exceed 3 feet.

ADjUSTING FOR ELEVATION

•Gas clothes dryers input ratings are based on sea level operation and need not be adjusted for operation at or below 2000 ft. elevation.

For operation at elevations above 2000 ft., input ratings should be reduced at a rate of 4 percent for each 1000 ft. above sea level.

•Installation must conform to local codes and ordinances or, in their absence, the NATIONAL FUEL GAS CODE, ANSI Z223.

PFMS455, PFMS450, PFDN445, PFDN440, PFDS450 specifications

The GE PFMN440, PFMN445, PFDS455, PFDS450, and PFDN440 are part of GE’s innovative family of radio frequency (RF) power transistors designed for various commercial and industrial applications. These devices are renowned for their efficient performance, providing a blend of high power output and reliability, ideal for telecommunications, broadcasting, and other RF applications.

The GE PFMN440 and PFMN445 are members of the RF transistor family that offer robust performance in high-frequency applications. The PFMN440 is particularly noted for its outstanding linearity and power gain, which makes it suitable for use in RF amplifiers and transmitters. Its compact package and advanced thermal management design enable efficient heat dissipation, which is critical in maintaining performance under load. The PFMN445, with a higher power rating, amplifies these characteristics, supporting greater output levels while maintaining linearity, resulting in clearer signal output.

The PFDS455 and PFDS450, on the other hand, are optimized for industrial applications with features that emphasize durability and efficiency. The PFDS455 stands out for its ability to handle higher voltages and currents, making it an excellent choice for applications that require resilience against overloads. The device's superior thermal stability ensures that it performs consistently across a range of operational environments. The PFDS450 shares many of these attributes but is tailored for applications requiring a slightly lower output, making it versatile for different RF circuit designs.

The PFDN440 is designed with specialized technologies that enhance its functionality in digital and mixed-signal environments. It integrates advanced semiconductor materials which reduce power consumption and improve efficiency without compromising performance. This device is particularly useful in applications that demand high-speed operation and reliability, making it a preferred choice for modern communication systems.

All these transistors utilize state-of-the-art manufacturing processes, including advanced doping techniques and epitaxial growth, which contribute to their excellent electrical characteristics. Their high thermal conductivity, high breakdown voltage, and wide frequency response range make these devices suitable for both commercial and specialized applications.

Overall, GE's PFMN440, PFMN445, PFDS455, PFDS450, and PFDN440 transistors are emblematic of modern RF technology, combining power, efficiency, and reliability to cater to a wide spectrum of RF applications.
