The Screw-FIX Rain Cap Ø 100 is an essential accessory designed for use with MI-FLEX 316 and 904 flexible flue liners. Crafted to the highest standards, this rain cap ensures comprehensive rain protection at the top of your chimney stack. Building Regulations Document J stipulates that flexible flue liners must be fully enclosed inside a masonry chimney.
With this in mind, the Screw-FIX Rain Cap is perfect for chimneys built to these regulations, supporting appliances up to 600°C (T600 designation). It is suitable for wood (<20% moisture), smokeless coal, gas, and oil appliances.This rain cap plays a critical role in preventing water, vermin, and birds from entering your flue system. Its design also aids in stopping excess water from passing through the system and causing potential damage to your appliance.
The cap must be used along with a top plate and clamp (the insert is not necessary). It’s important to ensure that your chimney structure, including pots and flaunching, are in good condition.Maintenance is straightforward; sweeping should be performed by a competent person, ideally a HETAS registered sweep, at least once a year. For solid fuel applications, it is recommended to sweep twice a year: both at the end and the start of the heating season.

Before installing the Screw-FIX Rain Cap, ensure that your chimney is a fully masonry structure as required by Building Regulations Document J.

Comprehensive Buyers Guide for the Screw-FIX Rain Cap - Ø 100
Choosing the right accessory for your chimney is a critical decision that impacts the safety, efficiency, and durability of your heating system. In this guide, we provide an in-depth overview of the Screw-FIX Rain Cap - Ø 100, detailing why it is a superior choice for your chimney, how it integrates into your overall flue system, and the additional accessories you might consider to complement your installation.
Product Overview
The Screw-FIX Rain Cap - Ø 100 is engineered from high-grade 316L stainless steel, ensuring longevity and resistance to the elements. Designed specifically for MI-FLEX 316 and 904 flexible flue liners, it meets the stringent BSEN 1856-2 T600 N1 W V2 L50012 G standard, making it suitable for appliances operating up to 600°C. Its robust construction not only enhances safety by limiting rain ingress and debris accumulation but also preserves the integrity of your entire chimney setup.
Why Quality Matters
Durability and Safety: Unlike lower quality alternatives, this rain cap is built to endure harsh weather conditions while maintaining its structural integrity. The premium stainless steel material protects against corrosion, an essential quality given the varying climates in the UK.
Compliance: Building Regulations Document J mandates that flexible flue liners must be completely enclosed within a masonry chimney structure. The Screw-FIX Rain Cap fulfills this requirement, ensuring that your installation remains both safe and legal. This product is an excellent match for conservatively designed chimneys and helps prevent common issues such as water damage, degradation of flue liners, and potential hazards from falling debris.
Installation and Maintenance
Installing the Screw-FIX Rain Cap is straightforward but requires careful attention to detail. It is vital that the cap is used in conjunction with a properly fitted top plate and clamp to guarantee a secure fit. Here are some key points to consider during installation:
- Professional Installation: Although the product is designed for ease of use, it is recommended that a qualified professional or a HETAS registered chimney sweep handle the installation. Their expertise ensures that the entire system is compliant with national regulations and operating safely.
- Condition Check: Prior to installation, inspect your chimney’s overall condition, including the state of chimney pots and any flaunching. This precaution helps avoid future complications.
- Regular Maintenance: For optimal performance, it is advised to have your chimney swept at least once a year. If your system involves solid fuel, consider sweeping both at the beginning and end of the heating season to minimise the risk of soot build-up and potential appliance malfunction.
Addressing Common Concerns
Can this rain cap be used on any chimney type?
No, the product is designed exclusively for masonry chimneys that can properly enclose flexible flue liners. Non-masonry chimneys do not meet the necessary safety standards dictated by Building Regulations Document J.
What about additional accessories?
This rain cap must be coupled with a top plate and clamp to ensure a secure and compliant installation. Should you need further accessories, be sure to explore complementary products offered by National Flues that are engineered to work together seamlessly.
Is maintenance complicated?
Not at all. With periodic inspections and routine sweeping, maintaining your chimney system becomes a straightforward task. By ensuring that your chimney is clear of obstructions and in good repair, you not only protect your investment but also enhance the longevity and efficiency of your heating appliance.
