Is it safe to use a propane fireplace with the flue closed?

Answer 1

Only if you don't mind risking a really long Winter's Nap. You need to have proper ventilation or the fumes can build up and become dangerous.

Answer 2

You need to carefully read the CERTIFIED operating instructions for that appliance and follow them precisely. Do not take the word of a plumber, or a gas fitter or anyone else on this forum! The risks are way too high. You are gambling with your life! The only authority on how that particular appliance is to be operated, is the original manufacturer. That being said...There are still come dangerous contraptions in existence called "vent-free" appliances. They are designed as a purely decorative unit and are not meant to provide any real heat for an extended period of time. They are illegal in MANY states, ALL of Canada, and MANY other countries. They burn the air you are breathing and put the products of combustion back into the air you breathe! It sounds like this is what you have there... I have many years experience in the propane business and I can tell you that there will never be one of those appliances operating in any home my family is in! I suggest you look into updating to a more modern unit. The best option is a "direct-vent" type. It draws air from outside, burns it with the fuel and then puts those products of combustion back outside. There is no communication of the flame with the air in the home. They use a heat exchanger to put the heat into the home and keep the bad stuff outside! If you are unable to get your hands on a copy of the manufacturer's CERTIFIED operating instructions, I strongly suggest you discontinue using the appliance at all.

Answer 3

while some propane heaters are designed and built to operate vent free,chances are that if the installers took the time and trouble to install a flue on yours it is not ventless.alot of the gas log type inserts are mainly for asthetic purposes.also while it is true that propane itself is not poisonous it can in some cases produce carbon monoxide when burning,install detectors.as a volunteer f.f. and first responder i would advise against using it with closed flue until you can find out for sure.(model or serial #should be labeled on controls inside fireplace.

Answer 4

They run Propane fork lifts inside all the time!

Propane is nontoxic; however, when abused as an inhalant it poses a mild asphyxiation risk through oxygen deprivation. It must also be noted that commercial product contains hydrocarbons beyond propane, which may increase risk. Propane and its mixtures may cause frostbite during rapid expansion.

Propane combustion is much cleaner than gasoline, though not as clean as natural gas. The presence of C-C bonds, plus the C=C bond of propylene, create organic exhausts besides carbon dioxide and water vapor. These bonds also cause propane to burn with a visible flam

Answer 5

NO! The propane supply hose might develop a leak, which could explode! Use only with adequate ventilation.Remember,Safety comes first.

Answer 6

I can't think of anything much more dangerous that you might try.
