For those ever thinking about heating water it's a good idea to have this option so you never over heat your water system and avoid pipes busting. We do have a thermometer to install to keep check of the water temperature and this system does has an emergency escape pressure pipe that reaches the height of our water storage tank, not sure of the correct terminology for this.
Scott in Iowa - I would say this statement, falls short on the advice required for heating water with a "uncontrolled fire" That being said, if you have a closed system or even one with a blow off (mandatory) and your fire is going great guns and power goes out. There is little a person could do even if your right there. And chances are you might not be. With a two part system- i.e. an open system for heating the water, and second system for circulation through the first heated water generally solves the worries. The open system, allows for total expansion, even if steam would develop. No pressure could develop other than steam blasting through the pipes to a completely open tank (or half full of water)
This is just advice, have plumbed a few and seen a few scary ones.
You can all look up the expansion rate of steam, but what many don't read, is just how fast and to what degree this can happen. (more than a blow off valve can handle on a closed system, if things are really cooking)

The vertical part should be in the firebox, directly above the port and hanging over that U-shaped piece. Proportions should be fitting for an 8" version.
