Keep AIR Filters Clean, Do not Obstruct Duct Work

6.D KEEP AIR FILTER(S) CLEAN

As a user, your personal responsibility is to keep air filter(s) clean.

CAUTION

A dirty air filter(s) reduces system efficiency and can cause erratic control performance. These could result in damage to blower motor or heat exchanger.

1.During the first four weeks after your furnace is installed, inspect your air filter(s) for dirt every week. Then check the filters monthly and replace as necessary.

2.If the filter(s) is of a washable type, clean filter(s) according to the manufacturer’s specifications.

WARNING

After cleaning or changing filter(s), filter access must be closed and latched. Failure to do so could cause nausea, asphyxiation, or fire resulting in damage, injury or death.

6.E DO NOT OBSTRUCT DUCT WORK

For proper operation, keep registers and return air grilles open. Do not cover or block them with rugs, carpets, drapes or furniture.

6.F HAVE YOUR FURNACE CHECKED ANNUALLY

The furnace, vent terminal, and the combustion air intake hood should be inspected yearly by a qualified service agency, generally prior to the heating season. Detailed procedures for this inspection are contained in the instructions booklet and should be handled by the qualified service agency only.

A general inspection of the furnace, the furnace area and the vent terminal should be conducted on a regular basis by the owner/occupant. This review should include:

1.Make sure the furnace always has the minimum clearance as detailed on the furnace rating plate. Special attention must be given to these items if any remodeling is done.

2.Make sure the vent terminal is in place and is physically sound.

3.Reviewing that the return air duct connection(s) is physically sound, is sealed to the furnace casing.

4.The physical support of the furnace is sound without sagging, cracks, gaps, etc. around the unit so as to provide a seal between the unit and the structure.

5.Inspect for any obvious signs of deterioration of the furnace.

6.Periodic examinations of the vent terminal should also be conducted by the owner on a regular basis, preferably every month but at least every two months during the heating season.

7.Check the entire vent terminal for any blockage. If any debris is present remove it.

8.If unit is vertically vented, inspect vent system annually including drain tube. Clean or replace if necessary.

6.G THE FOLLOWING PROCEDURE SHOULD

BE FOLLOWED FOR THE PERIODIC INSPECTION AS CONDUCTED BY THE OWNER/OCCUPANT.

1.Set the wall thermostat to the OFF position or lower the set point lever to a temperature well below the existing room temperature. Shut off electric power to the furnace. A circuit breaker is located behind the lower, small access panel on the right side.

2.Remove the burner access door. See Figure 4.

3.Use flashlight or trouble light to observe the burner compartment and burners. There should be very minimal scaling or sooting in this area. Any loose debris may be vacuumed out. Also observe the sides of the heat exchanger tubes for “hot spots” due to improper burner alignment or overfiring and give particular attention to any area where it looks like there may be any deterioration from corrosion or rusting. Observe for any corrosion on the burners themselves. Should anything appear questionable, contact your service agency.

4S, 5S, WG3S specifications

Bard WG3S, WG5S, and WG4S are advanced wind turbine systems designed to harness wind energy efficiently and sustainably. These turbines are part of a growing movement towards renewable energy solutions, aiming to reduce reliance on fossil fuels and mitigate climate change.

The WG3S, a compact and versatile model, has been engineered for optimal performance in a variety of wind conditions. Its notable feature is the composite rotor blades that maximize aerodynamic efficiency while minimizing noise. The turbine also incorporates a state-of-the-art pitch control system, allowing for real-time adjustments to blade angles, thus enhancing energy capture and reducing mechanical stress during high wind events.

The WG5S model takes performance to the next level with its larger rotor diameter, increasing the swept area significantly compared to its predecessors. This enhanced design enables it to generate more electricity, making it ideal for both onshore and offshore installations. The WG5S also features a sophisticated control system, utilizing advanced software algorithms to predict wind patterns and dynamically adjust operational parameters. This ensures optimal performance under varying environmental conditions.

Meanwhile, the WG4S serves as a robust mid-range option that balances power output and cost-effectiveness. It employs advanced materials in its construction, offering durability against harsh weather conditions while maintaining a lightweight structure. One of its key characteristics is the integration of smart technology, allowing for remote monitoring and maintenance scheduling. This helps to optimize uptime and minimizes operational costs.

All three models utilize cutting-edge technologies in their generators, including permanent magnet generators that provide efficient energy conversion with reduced energy losses. Additionally, they are equipped with advanced gearbox systems that facilitate smooth energy transmission and enhance reliability.

In conclusion, Bard's WG3S, WG5S, and WG4S wind turbines exemplify the latest advancements in wind energy technology. Their main features, focusing on performance, efficiency, and sustainability, position them as leading solutions in the renewable energy sector. With a commitment to innovation, Bard is at the forefront of providing effective and scalable wind energy systems that contribute to a cleaner, greener future.
