CO2 Placement

[Allan Waghalter]

What's the current thought on placing CO2 detectors? I am working on a
three story house with a wine-cellar basement. Its a restoration of an old
mansion here. Do I need to put a detector on each floor? How high should
they be? Which detector do you recommend?
Thanks in advance for the input.

What type of heat?
I'd keep them low on and on the level lower then the combustion heat.

 

[Allan Waghalter]

I think the heat will be gas. There are gas lines running through the house
leftover from the original construction. There are 8 fireplaces! Will
expect some trouble with the smoke detectors as the fireplaces are in all of
the bedrooms.

Do you mean "CO", or "CO2". Two completely different gasses with
completely different properties so detector placement will be critical.

I think it would be wise to just read the directions and follow the mfg.
recommendations for installation of the unit in question.

The recommended height is 5 feet above the floor ("breathing height," according to one manufacturer). Place a detector outside each
bedroom and consider placing one near the furnace if it's gas fired. The same applies to fireplaces and other places where
combustion air has the potential to mix with room air.

Some manufacturers recommend against placing CO (not CO2 by the way) detectors inside bedrooms due to problems with aerosol
propellant (hairspray, for example).

Well what if there was a massive soda bottle rupture due to global warming,
you could suffocate on all the carbon dioxide.

Not if your CO2 detector is located PROPERLY.

5 ft seams awful high, if I laying in bed I'd want 2-3 ft

Perhaps so. Absent a spec from UL I just follow the manufacturer's instructions. ISTR Macurco says 5 feet up. YMMV.

Additional comments:

I just noticed a change in Macurco's recommendations. They now suggest bedroom locations as well for their CM-S1 detector. I guess
they've licked the problem with aerosol propellants.

FWIW, they're a good brand. If you've not yet settled on one, you may want to consider them.

And that presumably, based upon my near-fatal experience with putting too
much dry-ice in a monster fog machine, would be UNDER the sody-pop.

I put in a GE couple of weeks ago and they recommended 5 fff and Up...even
on the ceiling, which is where I put it; above the mbr door.

I think if everyone would simply read all of the opinions that have
been posted in this sage group in the past, regarding the placement of
CO detectors and taking a consensus of all those opinions, it would be
quite clear to anyone with any intelligence at all ...... that it was
ok to mount a CO detector anywhere. As long as the main panel had and
earth ground ..... ummmm .... or didn't.

Please remember to ground your plastic back boxes too.

like in this faq...

http://www.faqs.org/faqs/electrical-wiring/part2/

a little part of it....Subject: Should I use plastic or metal boxes?

The NEC permits use of plastic boxes with non-metallic cable
only. The reasoning is simple -- with armoured cable, the box
itself provides ground conductor continuity. U.S. plastic
boxes don't use metal cable clamps.

The CEC is slightly different. The CEC never permits cable
armour as a grounding conductor. However, you must still
provide ground continuity for metallic sheath. The CEC also
requires grounding of any metal cable clamps on plastic boxes.

The advantage of plastic boxes is comparatively minor even for
non-metallic sheathed cable -- you can avoid making one ground
connection and they sometimes cost a little less. On the other
hand, plastic boxes are more vulnerable to impacts. For
exposed or shop wiring, metal boxes are probably better.

Metal receptacle covers must be grounded, even on plastic
boxes. This may be achieved by use of a switch with ground
connection.

The problem is there isn't a consensus.
Different manufacturers specify different
locations. I follow Macurco's advice
because that's my favorite brand. I
understandf their reasoning though, and
I agree with them. CO mixes readily with
air. Although it is warmer than air when
it first emerges from the fire, it quickly
mixes, especially if being pushed through
a forced air HVAC system.

If I installed one in a furnace room I'd place
it at ceiling height. But in or near bedrooms
I would go with the 5 foot height. YMMV.

I ground my plastic boxes with fiber optic cable, allows for faster
transmutation of electrons.

I prefer to use bungee cords. The elasticity helps deal with changing voltages.
