I am working on my second reverse flow using half of a 176 gal propane tank. First one failed miserably. On the first one, the firebox is mounted too high, and it is also too small.
Here is the first one before I made some modifications:
I have since changed the exhaust stack to 4" square tubing, and moved it to the top of the cooking chamber, because it wasn't drafting at all. I also added two vent to the firebox to help with airflow. It will currently hold 250, but not much more.
On my next one, I am going to use a 40 gal water heater for the firebox, which is overkill, but I have read enough posts on here that state that too big of a firebox won't hurt too much.
Here is the idea I have for placement of the firebox perpendicular to the cooking chamber:
Here's the water heater with the door cut out, and I am trying to figure out how to do the vents. I am almost tempted to move the pipe in the center to the bottom, and drill holes into it for the bottom vent.
Any ideas on how to attach a vent to the round surface?
