The Triplelock GC1 Gas Terminal with a 150mm diameter is essential for safely terminating flue liners connected to gas-fired appliances. Designed specifically for gas terminals, this cowl ensures efficient venting, protecting your home from potential gas buildup. To install, simply place the terminal over the exposed flue liner and secure it with a stainless steel screw.

For a lasting weatherproof seal, apply acid-resistant cement around the clamp plate, extending up to the bottom holes of the cowl. Routine maintenance is key for safety—chimneys serving gas or oil appliances should be swept and checked annually to ensure optimal performance.

To install the Triplelock GC1 Gas Terminal, begin by placing the terminal over the protruding flue liner from your gas-fired appliance. Secure the unit with a stainless steel screw. For a long-lasting and weatherproof seal, carefully apply acid-resistant cement around the clamp plate, ensuring coverage up to the bottom holes of the cowl. Regular maintenance is recommended, with an annual chimney sweep and detailed inspection to ensure the flue system operates efficiently. Although many homeowners install the terminal themselves, professional installation is advised for optimal safety and regulatory compliance.

The Triplelock GC1 Gas Terminal is designed to safely terminate the liner on gas-fired appliances, ensuring efficient and secure venting.

To install the GC1 terminal, place it over the protruding liner and secure it with a stainless steel screw. Apply acid-resistant cement for a weatherproof seal around the clamp plate up to the cowl's bottom holes.

Chimneys serving gas appliances should be swept and maintained at least once a year to ensure the terminal and flue system work efficiently.

While primarily designed for gas appliances, the terminal can also be used with oil-fired appliances but maintenance frequency might change.

While it's possible to install the terminal yourself, professional installation is recommended for ensuring it is correctly and securely fitted.

The Triplelock GC1 Gas Terminal is made from high-quality stainless steel for durability and reliability.
