I’m going to pick up a 7x14 enclosed trailer on Wednesday. I’m putting a 8gpm hot water skid towards the rear. The way the skid is built, I will have to add some length to the muffler. I plan on going to a muffler shop and letting the pros take care of that. Should I vent it straight out the back in the same direction the burner will be blowing? Or duct it to the floor? My first choice to to just have them make a 90 with about 1 1/2 ft length pointing towards the back. Currently the exhaust will be blown into the trailer.
Most importantly, my plan is to use this marine bilge air blower and some 4” ducting to bring in fresh air near the engines air filter.
My question is: does this sound like a solid plan, or am I overthinking it. I’ve seen several enclosed rig in various places of the internet with the hot water skid just towards the back. No fans, blowers, vents, etc. I also have read here on the forum that ventilation in an enclosed trailer is necessary for the longevity of the equipment.
The last question: can I run this off of the skids battery without problem?
