Gasket Replacement

The Dutchwest Gas Heater uses a ‘tadpole’ type gasket to seal between the glass panel and the frame. In time, this gasket can become brittle and compressed and should be replaced. New gasket is available from your dealer.

Shut off the gas supply and allow the stove to cool. Wear safety goggles and a dust mask.

1.Remove the Front, Glass Frame and Glass Panel. (Figs. 36, 37) Remove the old gasket. Use a razor blade, with rounded corners, to separate the glass and gasket from the frame, and to clean the glass of any remaining cement or bits of gasket.

2.Determine the correct length of gasket by laying it out around the edge of the glass. Allow an extra 1 - 2” (25-50mm). Mark the spot to be cut. Use a utility knife.

3.Starting on a long edge, remove about 6” of the protective paper strip and apply the flat adhesive face of the gasket around the outside-facing edge of the panel. Continue around the panel, applying about 6” at a time and being careful to not stretch the material. Do not overlap the gasket ends. (Fig. 38)

4.Apply a thin bead of high temperature silicone rubber sealant along the inside corner of the glass frame, all around the perimeter. Place the flat gasketed side of the glass panel back into the steel frame. Pinch the rounded inside-facing gasket material to bulk it up.

5.Replace the glass frame and front panel as previ- ously described.

Inspect the Vent System Annually

Have the vent system inspected annually by a quali- fied technician. Shut off the main gas supply before inspecting the system. Both the inner exhaust pipe and the outer combustion supply pipe must be checked to confirm that they are unblocked and in good condition.

Check the Gas Flame Regularly

To ensure that the stove is operating properly, check the flames periodically to confirm they match Figure 39. The flames will be blue during the first 15-20 minutes of operation, and will gradually turn to yellow.

Do not use your stove if the flame pattern differs from that shown here. Contact your Dutchwest dealer or a qualified technician for help.

Stove Disassembly

If there is ever a need to remove the firebox assembly from the stove shell, support the firebox with solid stands about 6” (150mm) tall under the left and right outer edges of the firebox base. Do not set the firebox assembly directly on the floor; this can damage the control valve and/or the gas lines from the valve to the firebox.

Before removing the firebox from the shell, disconnect the on/off switch wires from the valve. If the assembly includes the optional fan, disconnect the fan rheostat. If the installation includes a wall thermostat, disconnect the thermostat leads from valve.

Disconnection and reconnection to the gas line should only be done by a qualified gas service technician.

Upon reinstallation, the vent system must be sealed to the firebox as shown in the installation section, Page 9. Also be sure the logs are placed in the firebox correctly, as shown on Page 11, Figures 21, 22.

2468, 2467, 2468 specifications

CFM Corporation has established itself as a powerhouse in the aviation industry, particularly through the design and manufacture of high-performance aircraft engines. Among its standout products are the CFM 2468 and 2467 engines, which have garnered attention for their state-of-the-art features, innovative technologies, and impressive performance characteristics.

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.
