Majestic Fireplaces® UVC / UVS Vent-Free Heaters

High Elevations

Input ratings are shown in BTU per hour and are certified without deration from elevations up to 4,500 feet (1,370m) above sea level.

Nuisance outages may occur at altitudes above 4,500 feet (1,370m) if dirt, dust, lint and/or cob- webs are allowed to accumulate on burner and/or ODS pilot. Monthly inspection and cleaning is recommended for altitudes above 4,500 feet (1,370m)

For elevations above 4,500 feet (1,370m), instal- lations must be in accordance with the current ANSI Z223.1/NFPA 54 and/or local codes having jurisdiction.

The installation of your Majestic Fireplaces room- heater must conform with local codes, or in the absence of local codes, with National Fuel Gas Code, ANSI Z223.1/NFPA 54 — latest edition. (EX- CEPTION: Do not derate this appliance for altitude. Maintain the manifold pressure at 3.5 inches w.c. for Natural Gas and 10 inches w.c. for LP gas.)

Gas Supply Pressures

This heater must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure equal to or less than 1/2 psig (3.45 kPa).

The heater and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPa).

Connect the Gas Line

If gas piping from the source to the heater location has not been accomplished, install the required pipe. Con- sult local plumbing code to assure proper pipe size.

The gas pipeline can be brought in through the right or left side of the heater, as well as the bottom. Knockouts are provided at convenient locations to allow for the gas pipe installation and testing of any gas connection. It is most convenient to bring the gas line in from the right side, as this allows fan installation or removal without disconnecting the gas line.

NOTE: The gas line connection can be made with properly tinned 3/8" copper tubing, 1/2" rigid pipe or an approved flex connector, then reduced to 3/8" to the heater. Because some municipalities have some addi- tional local codes, it is always best to consult your local authority. Consult the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.

Its advanced materials and aerodynamic design allow for reduced weight and increased durability. The UVS43 employs state-of-the-art technologies, including a full-authority digital engine control (FADEC) system which optimizes engine performance by intelligently adjusting parameters in real-time.

Similarly, the UVS36 model is known for its versatility and adaptability in various aviation platforms. The engine incorporates a unique dual-spool design that provides improved efficiency at different altitudes and speeds. The UVS36 is equipped with advanced noise reduction technologies, ensuring compliance with stringent environmental regulations without compromising on performance.

The CFM UVC36 is another standout in the CFM engine lineup, designed specifically for regional aircraft. It features a compact design that allows for easy integration into smaller airframes while providing reliable thrust and performance. The UVC36 employs innovative cooling technologies that enhance engine longevity and reduce maintenance intervals, making it an attractive option for operators concerned with operational costs.

On the other hand, the UVC43 is tailored for larger aircraft, offering increased power output and efficiency. This model utilizes advanced composite materials, allowing for a lighter engine that still delivers exceptional performance. The UVC43 is also notable for its improved fuel consumption rates compared to previous models, thanks to its advanced turbine and combustion chamber design.

All four engine models share a commitment to sustainability, featuring reduced emissions and noise levels while enhancing operational efficiency. The integration of cutting-edge computer modeling and simulation techniques during the design phase has contributed to optimized performance across all models. With their combination of innovation, flexibility, and reliability, the CFM UVS43, UVS36, UVC36, and UVC43 engines represent the future of aviation powerplants, meeting the demanding requirements of modern air transport while ensuring a reduced environmental footprint. As aviation continues to evolve, CFM remains at the forefront, driving advancements that shape the industry.
