Chimney for Gas Boiler

Specializing in the production of chimney for gas boilers, we offer a high-quality solution for efficient ventilation.

Advanced Laser CNC Welding Technology

Our chimneys are manufactured using advanced laser CNC welding technology, ensuring precise and durable construction.

Fully Automatic Imported Surface Spraying Assembly Line

We utilize a fully automatic imported surface spraying assembly line, guaranteeing a flawless finish and enhanced corrosion resistance.

Material

Our chimneys are available in two variants:

• Non-condensing chimney: The inner pipe is made of welded aluminum, while the outer pipe is constructed from galvanized steel sprayed or welded aluminum sprayed.


• Condensing chimney: The inner pipe is made of PP plastic, and the outer pipe is composed of galvanized steel sprayed or welded aluminum sprayed.

 

Installation Recommendations

To ensure optimal performance, we recommend the following installation guidelines:

• Tilt the chimney down by 5 degrees during installation to prevent rainwater from flowing back into the gas boiler along the smoke pipe.


• Allow a slight downward angle in the exhaust chimney to aid in the elimination of condensation caused by cold temperatures.


• The total length of the chimney pipe and extension pipe should not exceed 3 meters to avoid any negative impact on the boiler due to backflow.
