A direct-vent wall furnace is a self-contained enclosed combustion heating appliance that warms interior air by circulating it around a sealed chamber and vents combustion byproducts outside the building. They are not linked to ductwork and are permanently fixed to the structure of a house.
This means they don't need a chimney and can be mounted on almost any exterior wall. Direct-vent wall furnaces use gravity to circulate warm air, but some models also have a rotating fan. They're a great alternative to a central furnace if one isn't available, and they're usually less costly.
The fact is that Direct Vent Propane heaters are incredibly safe, cost-effective to run, and have been shown to meet today's stringent air quality requirements when properly sized and maintained. And as long as customers demand energy-efficient goods, vent-free appliances have a bright future.
Carbon monoxide is a byproduct of incomplete gas combustion and is often caused by inappropriately adjusted appliances. Propane appliances that are properly maintained will create an "ideal burn" during combustion, posing no risk of carbon monoxide poisoning.
All gas-burning items that draw combustion air from the living room "take oxygen" from that space (Gas ranges are vent-free units). Our products' owner's manuals, as well as your local code official, will advise and educate you on the need for make-up combustion air.
The ODS (Oxygen Depletion Sensor) on vent-free heaters automatically shuts off the gas supply if the oxygen level in the room falls below 18 percent. This is above the ANSI-recommended safe levels (American National Standards Institute). Is it possible to use unvented propane heaters with this in mind?
