It is important to remember that your furnace, refrigerator, water heater and range
all may use propane to operate. Each has a different BTU rating, and you will
need to consider them to determine how long your propane supply will last. Most
RV gas appliances are operated intermittently. Propane consumption depends on
individual use of appliances and the length of time operated. Unless there is heavy
use of hot water, the water heater consumption of propane is minimal. During cool
temperature or high wind conditions, furnace consumption can be extremely high.
To calculate your propane supply, take the BTU ratings for your propane
appliances and divide that into the BTU availability. Each gallon of propane (3.86
liters) produces about 91,500 BTU’s (46,514 kilojoules) of heat energy.

Unlike homes, the amount of oxygen supply is limited due to the size of the
recreation vehicle. Proper ventilation when using the cooking appliance(s) will help
you avoid the danger of asphyxiation.
It is especially important that cooking
appliances not be used for comfort heating, as the danger of asphyxiation is
greater when the appliance is used for long periods of time. FAILURE TO
COMPLY MAY RESULT IN DEATH OR SERIOUS INJURY.
The following warning labels are located in the cooking area to remind the user to
provide an adequate supply of fresh air for combustion.
