The installer must inform the owner/operator of
this appliance that precautions must be taken to
protect the appliance from physical damage.
This appliance produces radiant heat. Therefore,
it must be located at least 6 feet away from
any propane/LP gas container and must not be
directed toward any propane/LP gas container
within 20 feet.
The heater must be installed in a location such that
it will not be exposed directly to water spray, rain
and/or dripping water.
Use of this heater in a draft/windy area decreases
its efficiency. If possible, operate the unit in a
draft free area.
CONNECTING TO GAS SUPPLY
This model may be connected to a self-contained
propane/LP gas supply system using the hose and
regulator assembly supplied with the appliance
OR, it may be connected to a permanently installed
propane/LP gas supply system.
If connected to a self-contained propane/LP
gas supply system, the hose assembly must be
inspected prior to each use of the heater. If it is
evident that there is excessive abrasion or wear or
if the hose is cut, it must be replaced prior to the
heater being put into operation.
WARNING: Never use a fork
lift truck type cylinder.
The connection to a propane/LP cylinder must be
made in a well ventilated area using the regulator
and hose assembly supplied with the appliance.
DO NOT attempt to adjust this regulator. It has
been preset at the factory to provide safe and
proper operation of the appliance. Use a 7/8" open
end wrench to connect the POL fitting (supplied
with the propane/LP regulator) to the propane/LP
cylinder. Turn the POL nut in a counterclockwise
direction (left hand thread) until tight. DO NOT
use pipe compound on POL threads.
The heater must be located at least 6 feet away
from any propane/LP cylinder and must not be
directed toward any propane/LP cylinder within
20 feet. If more than one heater is used, they
and the supply cylinders must be separated by at
least 20 feet.
The gas supply must be turned off at the propane/
LP supply cylinder when the heater is not in use.
When the heater is to be stored indoors, the con-
nection between the propane/LP supply cylinder
and the heater must be disconnected and the
cylinder removed from the heater and stored in
accordance with Chapter 5 of the Standard for
the Storage and Handling of Liquefied Petroleum
Gases ANSI/NFPA 58 .
If connected to a permanently installed propane/
LP supply system, the system requires the use
of a two-stage gas regulator assembly which is
normally provided by your propane/LP dealer as
part of the propane/LP supply system. Consult with
your local propane/LP dealer for details concern-
ing proper equipment and installation.
Piping must be clean and free from scale or
burrs.
WARNING: Never use a flame
for gas leak testing.
