Notes :
1. Exhaust volume should be determined by the exhaust hood
manufacturer based on their products listing and local code
requirements. States such as California, Oregon, Washington, and
Connecticut all have code driven maximum exhaust volumes for specific
equipment. For example: California mandates that solid fuel exhaust

for solid fuel.
2. Spark arrestor type filters are required for solid fuel equipment.
3. A hood serving our solid fuel equipment must be dedicated to our
