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 specific 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. If more or less favorable conditions prevail at a
specific site, adjustments can be made on the basis of
experience.
If more than one gas supply container is used per heater,
the containers must be manifolded together to allow
vapor withdrawal simultaneously from multiple containers.
Manifold system shall be in accordance with NFPA 58 or
CSA B149.1.
