I just moved into a new home and will be re-setting up my electric brew rig. I have a 50amp control panel. HLT has a 5500 watt element controlled by a PID and the BK has a 4500watt with a PWM control. I have an area in the utility room of my basement that seems pretty well set up for this. It has a utility sink already installed and my brew stand will fit nicely right next to it. The main electrical panel is in this room. I plan to install a 50amp GFCI breaker directly in the main panel - the receptacle can go about 6 from the panel so its an easy short run. My concern is my limitation for getting make-up air into this room. I will have to drill two 4 holes through the side of the house one for exhaust and one for make-up air. I am very limited in where these can go. The make-up air intake will be only 2-feet from where the furnace exhausts through the side of the house. Im thinking of using 4 PVC for the intake and turning the exterior face of it away from the furnace exhaust. Just looking for some thoughts on whether this will provide sufficient clean air intake.
