All access doors are opened. The fan is dismantled, cleaned and reconditioned.<\/p>\n<h2><b>Best practices <\/b><\/h2>\n<p><b>Clean grease filters weekly<\/b> with a commercial degreaser. Clean filters improve efficiency.<\/p>\n<p><b>Wipe down the visible hood interior after each use<\/b>. Monitor air flow.

An island is an open space with appliances up to 70 kW. Both require compliant ventilation, but with different requirements.<\/p>\n<\/details>\n<details>\n<summary>Can I clean my system myself?<\/summary>\n<p>Daily filter cleaning can be carried out by your own staff. Complete duct cleaning must be carried out by a certified company to obtain the certificate required by the authorities and insurers.<\/p>\n<\/details>\n<details>\n<summary>Does my new system need to be inspected?<\/summary>\n<p>Yes. Even when new, a system will quickly accumulate grease depending on your cooking volume. The initial inspection establishes a baseline and confirms the conformity of the installation.<\/p>\n<\/details>\n<details>\n<summary>What happens if I refuse to comply?<\/summary>\n<p>You risk fines, temporary closure, increased or denied insurance coverage, and increased liability for fires caused by negligence.<\/p>\n<\/details>\n<details>\n<summary>Do fast-food restaurants have the same obligations?<\/summary>\n<p>Yes, if total power exceeds 20 kW. The type of service does not affect the requirements. Only the volume and type of cooking determine the frequency of maintenance.<\/p>\n<\/details>\n","protected":false},"excerpt":{"rendered":"<p>Do you run a restaurant, cafeteria or catering service in Quebec?
