make sure it turns the heater on and off within a
temperature differential of ±3°F (±1.5 °C).
19. Take time to understand how to operate and
maintain the heater by using this Owner’s
Manual. Make sure you know how to shut off
the gas supply to the building and also to the
individual heater. Contact your fuel gas supplier if
you have any questions.
20. Any defects found in performing any of the
service or maintenance procedures must be
eliminated and defective parts replaced imme-
diately. The heater must be retested by properly
quali
fi ed service personnel before placing the
heater back into use.
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 follow-
ing 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 speci
fi c site, adjustments can
be made on the basis of experience.
* Cylinders must be manifolded together to allow simultaneous vapor withdrawal from all cylinders.
