fresh air vent question

I have a manufactured home with a full unfinished basement. My water heater is located in the upstairs closet and is propane with a intake vent dropped into the basement. We installed a high efficiency furnace in the basement that has a pvc exhaust and intake pipe installed on this. I also added a wood insert fireplace that is vented into the basement also. My question is that I have a 6 inch flex coming from the outside and drops into a 5 gallon bucket above the floor about 12 inches for makeup/combustion air. I also cut a 6 inch grill register in my return air in the basement also after installing the fresh air vent. I currently run a dehumidifier in the basement at all times around 45%. Is it okay to have this setup the way I do is all I am wondering and hope to hear some input if this is wrong. Thanks

honestly, it sounds bad... every appliance should have its own fresh air intake if ones required.

So you feel that a 6 inch flex from the outside isn't enough to supply a water heater,fireplace and overall pressurizing of the home? The grill I cut in the furnace return is just for supplying some fresh air to the upstairs. What should I change?
