48 Inch Range and 'Make UP Air'
Are there certain rules regarding make up air? We will be installing a 48 in range with 54 inch hood. We want to do 600 cfm with 8 inch duct to hopefully eliminate the possibility of needing make up air. It will be rare that we are using all 6 burners simultaneously. Not even sure this is possible as all I read is recommendaiton of 10 inch duct and ~1000 cfm.
The size of the kitchen is ~300 square feet and the wall of the range is up against the garage wall. The duct will go directly out to the garage (horizontally) and then bend to go out of the side of the garage (~15 feet or so).
We are using r19 insulation so our home isn't as airtight that foam would indicate. Not sure if this is used in calculation for need of make up air.
Any guidance/thoughts would be appreciated!
THanks so much!!!
