Dutchwest Natural Vent

Certified to:

ANSI Z21.86b-2001 / CSA Z2.33b-2001

Vented Gas Fireplace Heaters

The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 - latest edition. (EXCEPTION: Do not derate this appliance for altitude. Maintain the manifold pressure at 3.5” w.c. for Natural Gas and 10” w.c. for Propane.)

High Elevations

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

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

In Canada, please consult provincial and/or local authorities having jurisdiction for installations at elevations above 4,500 feet (1,370m).

WARNING: Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage. Refer to this manual for correct installation and operational proce- dures. For assistance or additional information consult a qualified installer, service agency, or the gas supplier.

Venting Requirements and Options

The Dutchwest must be properly connected to a listed 4” (100mm) Type B venting system or to an approved Class A masonry or factory-built chimney system. In Canada, a complete relining of Class A chimney systems is required.

The Dutchwest Natural Vent stove will accept decora- tive 6” (150mm) stove pipe around the Type B venting system, for aesthetic purposes.

Complete Type B vent systems are available from a number of manufacturers, and your dealer can usually supply one. Pipe sections from different makers are not interchangeable; do not mix pipe or vent sections from different makers. Follow the vent system manufacturer’s instructions.

The vent system should conform to the specifications of the National Fuel Gas Code, latest edition.

If connecting to a Class A chimney system, use 4” (100mm) single wall or 4” Type B vent connector. Single wall vent connector requires a minimum 6” (150mm) clearance to combustible surfaces.

Exterior chimneys may be subject to flow reversal or condensation. To lessen these conditions, enclose Type B vents in an insulated chase, or reline exterior Class A chimneys.

An approved pass-through device is always required, whether the vent system passes through a wall or a ceiling. Use a pass-through device from the same maker who supplies the venting system.

Venting terminals shall not be recessed into a wall or siding.

Vent Layout and Height Requirements

Venting for a Dutchwest can rise vertically through the home, or can pass through an exterior wall and rise along the outside of the home. Some codes require that a Type B vent system rising on the outside of the home be enclosed in a chase. Check your local codes for requirements.

The minimum vent system height for the Dutchwest Natural Vent Stove is 8’ (2.43m), (Fig. 7) measured from the top of the stove. To determine the minimum height the vent system must extend through or past the roof, refer to the 1993 edition of the National Fuel Gas Code.

The CFM 2468 engine is known for its remarkable efficiency and reliability. One of its primary features is the advanced fuel efficiency technology that minimizes fuel consumption while maximizing thrust. This is largely attributed to the inclusion of next-generation composites in the engine's fan blades and cases, which contribute to a lighter overall weight without compromising durability. As a result, operators benefit from lower operating costs, making the 2468 engine a cost-effective choice for airlines.

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.
