Venting Exhaust Through Roof of Warehouse

[dharden333]

Per our landlord, we are required to vent the exhaust for the Glowforge through the roof instead of through a vent in the wall. There are no windows to vent out of. We are due to move into this space in September, and the landlord wants a plan for the venting. Does anyone have sound advice on how to accomplish venting through the roof and be within code? This is in north Texas.

it’s like a dryer vent
there is minor amounts of heat, but there is smoke, I would very much suggest getting a in line booster fan in the chain.

as long as you have the opportunity run 6" vent pipe to the roof and make sure to get a water proof cap, and at the bottom of the run, put a “t” to catch any condensate / rain water - you don’t want moisture coming into your glowforge.

Do you know how hard it is to make an egress window air-tight?:tired_face: Over the past few months, I decided that exhausting out and up past our roofline was the way to go. Not only would it keep the exhaus…

I’ve been running this rig for the past four years – blasting out over 350 CFM means no smoke, no smell, no condensate, no animals in the pipe. No cap, either – the 45° downward facing exit makes it weatherproof.
