ARTE® NIREAS fireplace is delivered with a stainless steel cooling coil already installed in which you must install a
cold water supply
(Table 7.2.1, Line 9)
so in case the water inside the water jacket exceeds 95 o C the
overheating safety valve
(Pic. 6.1)
will open and rapidly cool the water jacket.
