When I ordered the built-in grill Sept. 24th online the promised delivery date was 1-2 weeks. The grilled was delivered October 29th with 4 colored sheets of Warnings that we didn't know when designing our grill island. The specs on the 24" T Series built-in grill did not mention vents should be incorporated in the structure the grill would fit into. We had to modify the already built stone structure. The airflow direction was not mentioned in the installation requirements when we ordered the grill. You did not meet our expectations. There is not a phone number listed to contact you so you can fix it. You can call me at 616-940-2745.
