Natural gas does not pose any danger under proper use and appropriate and properly maintained facilities. The review of these must be done every 5 years.

In case you smell gas, please don´t use any switches, buzzers, nor any electrical appliances. Open doors and windows to ventilate the area. Do not light matches or lighters under any circumstance and do not smoke. Close all controls of gas appliances and the general stopcock and do not open it again until the installation or faulty device has been repaired by qualified personnel.

Proper flame should be blue and straight. A yellow flame or one that rocks is an indication of poor combustion. Make sure you always turn the match or lighter on before switching on the gas.

To avoid accumulation of toxic gases produced by the combustion in the boiler you must place it in a ventilated place. Atmospheric boilers, unlike the sealed combustion boilers should have an exhaust for combustion products to the exterior and have to have good ventilation where they are located.
