in Gas Heating
My church has 2 free standing rinnai propane heaters in the lower classrooms, I am not familiar with this equip. as my exp. is mostly commercial, I noticed they don't have flues, got some feedback that said they have a sensor to lock out unit when CO in room is high, these rooms have very little fresh air , I would appreciate any info Thanks Rick

If in fact they are "vent free" heaters they do not have sensor for CO. That have and Oxygen Depletion System. Air is 20.9% oxygen. If there is no make-up air and the units run so long that they "deplete" or reduce the the 02 in the space then the system will shut down at about 18.5%.
How about a model number on these units. I can give you a bit more detail with that info. Also, are you sure they are vent free and not the direct vents?0 -
Thanks I will get the mod no. next time I go over there , not direct vented, A little scary to depend on a sensor to prevent a CO problem

In Massachusetts, they would have hard wired CO detectors, regardless of what is inside the units.
Many States/Jurisdictions have requirements on "Air Changes Per Hour" for places of assembly like churches, movie theatres, meeting halls etc.0 -
It also cant be the main heat source...just used as supplemental. Not a fan of any vent-free appliance. Is it really a good idea to be breathing the combustion gasses that are burning.?0

Well, its not that I don't agree with you, but as far as Massachusetts goes, "Vent Free" heaters are restricted to 36,000 BTU's or less and can't be used in bedrooms.
Although you don't normally put gas cook stoves in bedrooms, plenty of people use them for emergency heat and many new stoves I had installed were more commercial than residential, and if you were cooking a big Turkey feed, the gas output far exceeded that limit.0
