Tecnogas: Flue Systems and Gas Components

Gas Safety: Choose Standard-Compliant Flexible Hoses

Problem: Old blue rubber gas pipes have an expiration date (5 years) and must be replaced periodically to prevent dangerous leaks. People often forget to check them.

Solution: Switch to Tecnogas Stainless Steel Gas Pipes (UNI 14800) .
These flexible hoses, covered with a yellow fireproof sheath, have no expiration date . Once installed, they guarantee lifetime safety for connecting your hob or boiler, resisting heat and aging. A small investment for total safety in the kitchen.

Flue: Polypropylene (PP) or Aluminium?

Be careful not to choose the wrong material when purchasing boiler pipes:
🔹 Condensing Boilers: You must use polypropylene (PP) or special plastics (often translucent white). The fumes are cold (below 120°C) but acidic. Aluminum would corrode.
🔹 Traditional Boilers / Water Heaters: Aluminum (painted white) or stainless steel is used, because the fumes are hot and dry.
Always check your boiler manual before ordering bends or extensions!

Frequently Asked Questions about Tecnogas

1. Are Tecnogas flue pipes universal?

The pipes have standard diameters (60, 80, 100 mm), but the connection (male/female socket) may vary slightly between boiler brands or require adapters. However, Tecnogas produces universally compatible systems. The important thing is to always use the silicone gasket (often supplied) and lubricate it to ensure the flue gas is sealed.

2. Can I cut a coaxial pipe if it is too long?

Yes, coaxial or single extension tubes can be cut to size (male, smooth side). However, it's essential to deburr the cut well (file down the sharp edges) to avoid damaging the gasket when inserting it into the next piece. Remember to respect the measurements between the inner and outer tube for coaxial tubes.

3. Are extendable gas hoses safe?

Yes, Tecnogas expandable hoses are certified according to the UNI 11353 or 14800 standards. They can be extended (e.g., from 20 to 40 cm) to facilitate installation. However, the standard requires that they should never be installed fully extended to avoid mechanical stress on the fittings.
