Where can I find an installation detail for 4 levels of underground parking garage shaft (fire rated) sidewall exhaust fan and fire damper?
Confused on this. googled but cannot see how the fan and fire damper installed. right now, I have to use out of wall fire damper installation because the fire damper is larger than the opening and the exhaust fan size. someone ordered the damper larger than opening by mistake.
