Attached are the shop drawings. The hood O &M is found here, which has detailed
instruction on hanging the hood. The grease duct O &M is found here, which has detailed instruction installation. The
grease duct is ETL listed under file number 1000082319SAT -006 EEV and complies with UL 1978 and UL 2221
standards. If there are any questions, don't hesitate to respond.
Please let me know if this is acceptable or if you need anything else.
Thanks,
Paul.
