The vaporization of propane is affected by several factors:
the sur face 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 during winter in northern
climates. If more or less favorable conditions prevail at a
specific site, adjustments can be made on the basis of
experience.

Gas Cylinders to
Use Per Heater
* Cylinders must be manifolded together to allow simultaneous vapor withdrawal from all cylinders.

The heater must have the proper gas regulator for the
application. Use only the L.B. White regulator
originally supplied with the heater. This regulator
includes a POL fitting incorporating an excess flow
valve. The excess flow valve is a safety device which
protects against discharge from the propane gas
supply container if the regulator is broken off. If the
POL fitting is ever replaced, it needs to be replaced
with an L.B. White POL fitting. Failure to do so can
result in fires, explosions, loss of property, injury or
death.
12. This heater is configured for use for propane gas vapor
withdrawal only. Do not use the heater in an propane
gas liquid withdrawal system or application. If you are
in doubt, contact the L.B. White Co., Inc.
13. The heater must be installed so as not to interfere
with or obstruct normal exits, emergency exits, doors
and walkways.
14. Railing, fencing or suitable substitute materials must
be used to keep the heating equipment from any
people using and visiting the structure.
15. The unit shall be located so that rain, ice, or snow
drainage from the structure does not affect equipment
operation. If the unit is mounted outside, it must be
mounted above any pooled or standing water. If the
unit is to be located on the ground, a surrounding
trench is recommended to drain any rain, ice or snow
away from the unit.
16. The ground and surrounding terrain must be cleared
of any combustible vegetation and other combustible
materials when the heater is mounted outside.
17.
Eventually, like all electrical/mechanical devices, the
thermostat can fail. Thermostat failure may result in
an underheating condition. The thermostat should be
tested to make sure it turns the heater on and off
within a temperature differential of ±3°F.
18. Take time to understand how to operate and maintain
the heater by using this Owner’s Manual. Make sure
you know how to shut of f the gas supply to the
building and also to the individual heater. Contact
your fuel gas supplier if you have any questions.
19. Any defects found in performing any of the service or
maintenance procedures must be eliminated and
1.
Locate accessory package with handle and screws.
2.
Align handle to screws holes in case top. Install four
screws and tighten securely.
Note: The handle may be relocated to the side of the
top panel for heater stacking during storage. Do not
stack heaters more than two high.
