MAINTENANCE AND STORAGE
1. The heater should be inspected before each use, and at
least annually by a qualified person.
2. Before each use, check the soft "O" ring seat at the
bullnose of the POL fitting. If the "O" ring is cut, scuffed,
or otherwise damaged, replace it with part number 6681.
3. Turn off the gas at the LP-gas supply cylinder(s) when
the heater is not in use.
4. When the heater is to be stored indoors, the connection
between the LP-gas supply cylinder(s) and the heater
must be disconnected and the cylinder(s) removed from
the heater and stored outdoors and in accordance with
Chapter 5 of the Standard for Handling of Gases ANSI/
NFPA 58-1998.
SERVICING
A hazardous condition may result if a heater is used that
has been modified or is not functioning properly. When the
heater is working properly:
The flame is contained near the surface of the
ceramic grid(s).
The flame is essentially blue.
There is no strong disagreeable odor, eye burning or
other physical discomfort.
There is no smoke or soot internal or external to the
heater.
There are no unplanned or unexplained shutdowns of
the heater.
The parts list shows the heater as it was constructed. Do
not use a heater which is different from that shown. In
this regard, use only the hose, regulator and cylinder
connection fitting (called a POL fitting) supplied with the
heater. Do not use alternates. For this heater, the
regulator must be set to supply 28" water column (W.C.)
outlet pressure (1.0 psig). If there is any uncertainty
about the regulator setting, have it checked.
A heater which is not working right must be repaired, but
only by a trained, experienced service person. Contact
the factory for the service center closest to you, phone
number [phone].
You may also obtain in-warranty or out-of warranty service
by returning the product freight prepaid to:
Scheu Products Company
8855 Baker Avenue
Rancho Cucamonga, CA 91730
In-warranty products returned to the Service Department
will be repaired with no charge for either parts or labor and
will be returned to you freight prepaid. Please include a brief
statement indicating date, place of purchase, the nature of
the problem and proof of purchase.
Out of warranty products returned to the Service Depart-
ment will be repaired with a charge for parts and labor and
will be returned to you freight collect.
WARNING
Local codes for installation of propane systems may vary
considerably. Therefore, ask your local propane supplier
for advice on propane system installation in your particular
area. In the absence of local codes, install in accordance
with American National Standards Institute (ANSI)/Na-
tional Fire Protection Association (NFPA) publication 58-
1998 Standard for the Storage and Handling of Liquefied
Petroleum Gases and ANSI Z223.1/NFPA 54 National Fuel
Gas Code. Your supplier, fire marshal or library should
have copies of these standards.
The propane supply system must be arranged for vapor
withdrawal. Propane cylinders must be secured in the
upright position to keep them from falling or being knocked
over.

PROPANE FUEL INFORMATION
During use, liquid propane in a container vaporizes. As it
vaporizes, the propane cools itself. This cooling process
is known as the refrigeration effect. If it continues long
enough and proceeds fast enough, the propane tempera-
ture and pressure will fall so low that heater operation may
be improper or even impossible even though plenty of
propane remains in the container. Often frost forms on the
outside of the propane container as a warning of excessive
refrigeration.
Recommendations to reduce the ill effects of refrigeration
effect are:
Provide considerable more propane than you plan to
consume. As a rule of thumb, provide twice as much.
Fill containers frequently, especially in cold weather.
Never allow propane to fall below one-third of con-
tainer capacity.
If possible, keep containers in a warm area (under
no circumstances should the heater exhaust be
directed toward the propane container).
