Gas Supply Sizing
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 below 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 connected together by a manifold
to allow vapor withdrawal simultaneously from multiple containers. The manifold system shall be in accordance with
NFPA 58 or CSA B149.1.
