The new range of sealed chamber and forced draught water heaters in the TGFN LX series are manufactured in accordance with the new Low NOx 812-814/2013 standard and are designed for natural gas operation. For LPG operation add the LPG kit code.

The appliances are equipped with an electric gas valve and electronic flame ionisation ignition, and do not require a chimney as the entire path of gases and combustion fumes is totally isolated from the environment in which it is located. This process prevents any gas residues (especially in the case of liquefied gases) from giving rise to potentially dangerous situations.
