Do you make them pre heat the makeup air? Reason I ask is I have ran into this before and did not require them in to install heated makeup air (because the IRC does not require heated make up air like the IMC). Let me tell you at 900CFM it get pretty cold in the kitchen which makes for a very unhappy customer.

I am not happy until my customers are not happy!.....Just kidding.....I will suggest it (heating) if I ever come across it...I am sure it will be in the IECC soon...
