Draught Regulator Sourcing 3/4" — Model 90147AE06, 1200 mm flexible connector

The Sourcing draught regulator for 3/4" connections with a 1200 mm flexible connector is a mechanical device designed to stabilise the draft in chimney, flue or ventilation systems. It helps maintain a consistent combustion environment by compensating for variations in pressure and flow, reducing the risk of backdrafts or unstable flame conditions. The flexible 1200 mm connector allows for adaptable installation positions and easier alignment between the appliance outlet and the flue.

Advantages

This draught regulator provides steady draft control for small to medium heating appliances, improving combustion stability and operational consistency. The flexible connector simplifies installation in tight or offset configurations and reduces stress on joints. Constructed for installation in flue gas or ventilation lines, the device is suitable for environments where controlled air movement is necessary to maintain appliance performance.

Suitable for

• Domestic and small commercial boilers and burners requiring 3/4" connections
• Chimney and flue systems where draft fluctuations affect combustion
• Retrofitting existing installations that need a flexible connection of approximately 1200 mm

When it may not be suitable

The regulator may not be appropriate for large industrial furnaces or systems that require high-capacity draft management beyond the device's intended range. It is not intended as a substitute for system redesign where structural or regulatory requirements demand a different approach. Professional assessment is recommended where draft control needs are complex or where local codes specify alternative solutions.

Key specifications

• Connection size: 3/4"
• Flexible connector length: 1200 mm
• Function: mechanical draught regulation for flue and ventilation lines
• Application: stabilisation of chimney or flue draft to support consistent combustion

How to use

Install the draught regulator in the flue or ventilation line between the appliance outlet and the chimney according to manufacturer guidelines and local regulations. Use the flexible connector to align the regulator with existing pipework, ensuring secure, airtight connections at both ends. After installation, check for leaks and verify stable combustion under different operating conditions. Regular inspection and maintenance of the flue system and the regulator are recommended to ensure continued performance and safety.

What to consider before purchase

• Confirm that a 3/4" connection and a 1200 mm flexible connector match the dimensions of your appliance and flue route
• Verify compatibility with the type of fuel and appliance in use and check local installation regulations
• Assess whether the draught control range of a mechanical regulator is sufficient for your system or if a different solution is required

Usage recommendations

Have the installation performed or verified by a qualified technician, ensure all joints are sealed and tested, and include the regulator in routine flue inspections to maintain safe and efficient operation.
