FAQ
What material is the ducting made from?+
This ducting set utilizes galvanized steel, known for its corrosion resistance and ability to withstand varying temperatures. This makes it a reliable choice for both interior and exterior applications.
Is this ducting suitable for use with wood-burning stoves?+
While the material is resistant to heat, we don't recommend using this 100mm x 1.5m ducting directly as a chimney liner for wood-burning stoves due to potential carbon monoxide buildup. Consult with a qualified stove installer.
What tools will I need to install this?+
You’ll typically require a screwdriver or spanner (depending on fitting methods) and possibly a saw if you need to cut the ducting to length. Ensure you have appropriate safety gear like gloves and eye protection.
How do I connect this ducting to an existing vent?+
Connection is usually achieved via threaded fittings, which require careful alignment and tightening. Sealant tape can be used to ensure airtight connections and prevent drafts.
What are the typical applications for this size of ducting?+
This 100mm x 1.5m ducting is commonly utilized in extractor fan installations, ventilation systems for small outbuildings, and as a replacement flue liner for low-powered appliances.
Is there a maximum operating temperature for this product?+
The galvanized steel construction can withstand temperatures up to approximately 120°C (248°F). However, prolonged exposure to extreme heat should be avoided to prevent damage or deformation.
Does the ducting come with any fittings included?+
This listing provides the ducting only. Additional connectors and accessories may be required depending on your specific installation needs; these are typically sold separately.
How can I ensure a tight seal when connecting the ducting?+
Applying PTFE tape to the threaded connections before tightening is crucial for creating an airtight seal. Ensure you’re using the correct size tape and applying it in the appropriate direction – clockwise.
What is the weight of one 1.5m length of this ducting?+
Each 1.5m length typically weighs around 0.8 - 1.2 kg, depending on the wall thickness. Precise weights may vary slightly based on manufacturer specifications.
Can this ducting be painted or coated?+
Yes, the galvanized steel can be readily painted with suitable metal paints. However, ensure the paint is compatible with the material and allow it to fully cure before use, paying particular attention to areas subject to airflow.
