Field Control CAS-34U Fan-In-A-Can 120V Makeup Air Unit

Description

The Field Control CAS-34U Fan-In-A-Can 120V Makeup Air Unit is a versatile device used in combustion appliance systems to ensure proper ventilation and safety. Here’s a breakdown of its key features and functions:

Function:

• Provides combustion air for appliances: Delivers fresh air from outside to burners in furnaces, boilers, water heaters, and other combustion appliances.
• Prevents negative pressure: Combats the pressure imbalance caused by exhaust fans, ensuring proper venting and preventing backdrafting of flue gases.
• Improves appliance efficiency: Optimizes combustion with fresh air supply, leading to more efficient fuel burning and potentially lower energy costs.
• Enhances safety: Reduces the risk of carbon monoxide poisoning by preventing flue gases from entering the living space.

Key Features:

• Dual voltage compatibility: Operates on both 120VAC and 24VAC control systems, offering installation flexibility.
• Compact design: Fits easily in confined spaces near the appliance.
• Fan and pressure switch combination: Integrates both functions into one unit, simplifying installation and maintenance.
• Variable air volume control: Allows for adjusting airflow to match specific appliance requirements.
• Proven safety features: Includes a proving switch that ensures the appliance burner doesn’t operate until sufficient airflow is established.
• Durable construction: Features corrosion-resistant materials for long-lasting performance.
• Easy installation: Typically installed on an exterior wall near the appliance and connected to the combustion air intake.

Applications:

• Residential and commercial heating systems (furnaces, boilers)
• Water heaters
• Other gas-fired appliances like fireplaces and ranges

Things to Consider:

• Appliance compatibility: Verify the CAS-34U’s air output and pressure meet the specific requirements of your appliance.
• Local building codes: Consult local regulations regarding makeup air unit requirements for combustion appliances.
• Professional installation recommended: While DIY installation is possible for experienced individuals, consulting a qualified HVAC technician is recommended for optimal performance and safety when dealing with gas lines and ventilation systems.

Overall, the Field Control CAS-34U Fan-In-A-Can 120V Makeup Air Unit is a reliable and versatile solution for providing combustion air and ensuring proper ventilation in various gas-fired appliance systems. Its dual voltage compatibility, compact design, safety features, and ease of installation make it a popular choice for both homeowners and professionals.
