Chimney Cap Bratek Kula 100 mm, 2.5 kg, model 3828

Bratek Kula chimney cap model 3828 is a compact, durable termination for chimneys and flues with a 100 mm outlet. Weighing 2.5 kg, this chimney cap is designed to prevent ingress of rain, debris and small animals while allowing exhaust gases and smoke to vent effectively. It is intended for use with residential heating systems, stoves and small boilers that require a neat, space-saving chimney end.

Advantages

The chimney cap provides reliable protection against weather and external contamination without obstructing draft. Its compact spherical design minimizes turbulence at the outlet and helps maintain steady exhaust flow. Constructed to withstand typical outdoor conditions, the cap reduces the risk of blockages caused by leaves, twigs or birds and limits water entry that can accelerate corrosion in the flue. Installation requires only a 100 mm connection, making it suitable for retrofit and new installations with matching diameter.

Suitable for

• Residential chimney terminations for wood, pellet or solid-fuel stoves
• Small domestic boilers and heating appliances with 100 mm flue outlets
• Retrofit applications where a compact, protective chimney cap is needed
• Protecting chimney outlets from rain, debris and animals

Key specifications

• Outlet diameter: 100 mm
• Weight: 2.5 kg
• Model type: spherical chimney cap design
• Function: protects against rain, debris and animals while allowing smoke and gases to vent

How to use

Fit the chimney cap onto a 100 mm chimney or flue outlet, ensuring a secure and stable connection according to the flue manufacturer's guidance. Verify that the cap is oriented correctly and that there is sufficient clearance above the outlet to allow unobstructed exhaust. Periodically inspect the cap for signs of accumulation of soot, creosote or debris and clean as needed to maintain effective ventilation. If required, secure the cap with appropriate fasteners or clamps compatible with the flue material.

Usage recommendations

Perform routine inspections at least once per heating season and after severe weather. Remove deposits or nests that could restrict flow; if heavy corrosion or damage is observed, replace the cap to maintain safe operation of the heating appliance.
