Vent Gas

Can I remove the damper and connecting the vent pipe directly on top of the heater to gas?

I just installed a new 40 gal water heater gas in an external cabinet (where I took the old water heater out). I plugged the vent pipe directly on top of water heater gas. Is this normal? Do I really need a damper between the heater and the gas vent pipe?

Yes. You need. That's how it was designed to operate. It uses the hood for mixing the air with smoke and help them pull up and out. I am sure, if your water heater closet is adjacent to another structure, like the house, the wind goes all the way up past the roof because it is supposed do. I was called to houses in trust to fix or replace the hood was not installed correctly. This a security problem that would halt the sale of the house until the end. Without these openings, the heater can not vent properly and cause the combustion of hot gases and excessive abuse within the unit. Drafts could even turn off the pilot. Jerry-Rig do it and call it to do. Do it right and be safe.
