can carbon dioxide alarms detect gas leaks? also another question if there is a leak how long does it take before it blows up like if a leak just happen could it blow up right there and then? what are the signs of a gas leak?


Answer
No. Natural gas or LP gas is not CO2. If you happen to mean " Carbon Monoxide" alarm, CO, same case. (CO is the typical alarm type in residential applications) CO is odorless and very toxic to us.

Natural gas & LP has an odor added to it ( for detection by our noses). It has to be in the range 2.15% to 9.60% LP mixed to air to be explosive. Anything less or anything more, and it is not . (One of the properties that makes it desirable as an engergy source for our use)

It is also 1.52 the weight of air, so gravity keeps it low.

It would need an ignition source of 154 F. Most likely explosion range mixtures would be very shortly after a leak started and would exceed the max % range fairly shortly after that - so a small "window" for potential explosion.

Main signs of leakage is the "Smell" of the commercial additive. Verifying the leak with soap/water mixture on the pipe lines to locate the leak with "bubbles" showing.
There are also "LP Gas Detector" alarms available.

Can a NON vented heater be converted into a vented heater? By making a duct to feed the fire air from out side?

Can a NON vented heater be converted into a vented heater? By making a duct to feed the fire. With air from the out side, to the bottom of the heater. I was told the ONLY DIFRANCE between vented or (non) vented was having out side air to feed the fire.


Answer
No. A non-vented heater cannot be converted into a vented heater.
Gas heaters all work by burning gas (propane or natural) to produce heat. All of them produce some amount of Carbon Monoxide.
Vented heaters produce the heat in a sealed box with a vent or flue attached that sends the combustion gases to the outside world.
Non-vented do not. What you were told was close, but it's the exhaust, not the intake.
Non-vented, or "blue-flame" heaters produce very little carbon monoxide when working correctly. They also have sensors that turn the heater off if Co is detected.
But, when (not if) the heater malfunctions, dangerous levels of Co can build up in the living space, which can result in sickness and death.
If it isn't UL approved as a vented heater, it isn't one.
Best Of Luck
If you have a non-vented heater, get a Co detector, or two. Test them regularly.
