The vaporization of propane is affected by several
factors: the surface area of the container, the liquid
level of propane, temperature surrounding the
container, and the relative humidity. All of these
factors are speci
fi
c to a site. Therefore, a degree of
experience and judgement is required to select the
proper propane supply.
Although experience is the best guide, the following
recommendations can be used as a starting point.
The table is based on experience in northern
climates where cold weather and high humidity are
prevalent in the winter.
Propane Gas Supply Sizing

ence.
If more than one gas supply container is used per heater,
the containers must be manifolded together to allow va-
por withdrawal simultaneously from multiple containers.
