Curing Or ‘Burning In’ A New Fireplace When a new fireplace is lit for the first time, materials found on the external surfaces, such as paint, sealants, lubricating oils and gasket adhesives, can produce odours and a small amount of Carbon Monoxide (CO), a dangerous gas that can cause asphyxiation. This is called ‘curing ’ or ‘burning in,’ a process that can take up to 24 hours of run time. During this curing, the fireplace should burn for no less than five to six hours at a time with a high flame. Fireplaces generally operate on natural gas or solid fuel (wood, manufactured logs, pellets, etc.). If the fireplace is equipped with a fan, do not run it during the curing period. The fan cools the surfaces and will inhibit the curing process. Ensure your home is well ventilated during the curing process. If your home has a CO detector, it may detect CO and sound an alarm. During curing, the fireplace should burn for no less than five to six hours at a time with a high flame. 78 ANHWP.COM • ALBERTA NEW HOME WARRANTY PROGRAM
