“Range Hood Requirement This Samsung gas range has the following BTU: Total range BTU power: 58,000 Bake burner 19,000 Broil burner 16,000 Based on the overall total BTU power of 93,000 I bought a range hood with 900 cfm to be able to remove combustion gases, grease,etc. Unfortunately this could put the house in negative pressure increasing the risk of carbon monoxide poisoning from other gas operated appliances. To alleviate this, I need to install a make up furnace costing C$17,000.00 plus a whopping electric bill every month. What is the minimum required range hood's cfm to operate this gas range and sufficient to reduce any health risks associated with cooking with gas.”
