131.3. GENERAL SAFETY INFORMATION1.3.1. CARBON MONOXIDEAn installation that does not comply with the recommendations described in this manual can lead to carbonmonoxide emissions. As a safety measure, we strongly recommend for a carbon monoxide detector to beinstalled near the unit.Signs of a carbon monoxide poisoning (headaches, dizziness and nausea) are similar to those of influenza.If you have these symptoms, your fireplace may not have been installed correctly. Turn off the gas fireplaceand go outside immediately for some fresh air! Have the fireplace inspected by a qualified technician.1.3.2. GAS ODORPropane gas/LPG and natural gas are odorless. An odorant (usually sulfur) is added to each one of thesegases which makes them smell similar to rotten eggs. This will help you easily detect any eventual leak.However, the odor added to these gases can fade. Gas may be leaking without releasing any smell. Wetherefore strongly recommend that a gas detector be installed near the unit.
