What size hood over bbq

jgarden · Jun 30, 2015

I'm going to be installing a 42" lynx BBQ under a patio. I purchased BBQ and hood almost 2 yrs ago (same time I purchased house appliances during home remodel). Company sold me a 42 inch hood.

I've done some online research and it seems some folks recommend a hood that extends 4-6 inches beyond each side of BBQ. Information out there is very limited.

Does anyone have any real world first hand experience in this area?

Is it essential the hood be larger than BBQ when installing in a covered patio?

Thanks

Jack

Anyone? Bueller?

I'd make an anonymous call to a local building department and ask. As far as i can see the code only requires a vent hood of the same size. Because residential is more about the exhaust than fire suppression. If it were a commercial installation it might be different.

But I think your question was what is the best practice? That would be a over sized hood. Better yet a commercial hood with fire suppression.

not concerned about building code. I want to know what is needed to ensure all smoke is removed from patio area.

Then hood size is not the issue. As long as the fan in the hood is powerful enough to create a draft and draw the smoke to it. What is the CFM of the fan? Where is the grill placed?

Hoods are required by code in California, but you need to understand in some configurations these won't work at all. If the area is exposed to crosswinds even a light breeze can overwhelm the fan and push smoke into corners and dead areas. In those rare cases you have to design the kitchen so you work with the breeze.

Doubt there will be any wind at my planned location. I think the hood is 1200 cfm. Grill well be below the hood. I haven't built it yet so height is up to me.
