Connecting a gas boiler is one of the most important operations in the system software housing with heat. From proper choice materials and compliance technical requirements depends security, stability works equipment and duration its operation.
Which gas hose for a boiler is better? Modern and reliable the solution for connection is corrugated gas hose with stainless steel.
Why choose to connect the boiler corrugated stainless steel hoses
Corrugated stainless steel gas hoses gradually displace traditional rubber or PVC sleeves, because have a number of advantages:
- High strength and reliability. Stainless steel withstands significant mechanical loads, vibrations and pressure drops without risk. The corrugated structure provides flexibility without loss strength.
- Corrosion resistance. Unlike rubber sleeves, the metal sleeve does not age, does not dry out and does not crack over time. It withstands aggressive conditions and duration use.
- Increased fire resistance. Steel corrugated does not burn and does not support burning, which makes it safe element gas systems.
- Long term services. Metal hoses with steels often last 20 or more years, provided correct installation.
Features constructions corrugated gas hose
Corrugated hoses are manufactured from stainless AISI 304 or AISI 316L steel – resistant to corrosion and high temperatures. Their ends are equipped with:
- fittings under thread (usually 1/2″ or 3/4″);
- sealing rings;
- sometimes polymer insulating shell yellow color like Eco-Flex Gas Super hose.
Some models use additional reinforcement, for example, in Eco-Flex Gas EN14800 hose, which provides additional strength product.
Requirements for gas hose installation
The boiler must be connected with a corrugated hose in accordance with the requirements of DBN and safety regulations gas supply.
- Required use only certified hoses. On the product There must be a tag, passport and marking “for gas”.
- length. According to recommendations, the length should not exceed 1.5–2 meters (depending on the type of sleeve and requirements manufacturer). No tension or twisting.
- Sealing threaded connections. Allowed use:
- paronite or biconite gaskets,
- sealants that approved for gas systems,
- FUM-gas tape (yellow colors).
- It is forbidden:
- hide the hose in the wall or drywall,
- subject its strong heating from chimney or furnaces,
- create inflections under acute angle,
- install the hose too close to open flame
Advantages using corrugated hose specifically for boilers
Gas boilers working in the long-term mode, creating vibrations and heat load. Metal hose with steel effectively compensates for:
- temperature expansion,
- vibrations from the burner,
- small equipment movements during work.
It reduces risk of depressurization and breakdowns.
Corrugated boiler connection algorithm gas hose
- Shut off the gas supply.
- Verify thread and connectors elements on the boiler and gas tap.
- Choose the right hose length and diameter.
- Connect one end to the boiler, the other to the gas tap.
- Tighten the nuts with a wrench without excessive force.
- Verify connection soapy solution for absence leaks.
- Turn on the gas and do test run.
All works are performed only by certified gas industry specialists.
Corrugated hose with stainless steel – reliable, durable and safe solution for connecting a gas boiler. It provides tightness, resistance to temperatures and vibrations, as well as corresponds modern safety standards. When properly installed and used certified components such a hose guarantees stable and safe operation of boiler equipment for many years.
