LOCATING HEATER
The heater (and propane/LP gas supply cylinder
if applicable) must be located on a hard, flat, level
surface to minimize the risk of accidental tipping. If
an propane/LP gas supply cylinder is used (propane/
LP model only), the cylinder should be adequately
restrained to prevent accidental tipping. DO NOT
operate this heater with the supply cylinder in
any other than the upright position.
This appliance must be installed only in locations
where the potential for physical damage to the
appliance (i.e., due to physical contact) is reduced
to a minimum.
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.
PIPING
FOR MODEL 125-R (FOR USE WITH
PROPANE/LP GAS ONLY)
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 of model 125-R 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 ap-
pliance. 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 six 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 connec-
tion 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 (U.S.) OR CAN/CGA B149.2 (Canada) .
If connected to a permanently installed propane/LP
supply system, the system requires the use of a
two-stage gas regulator assembly which is nor-
mally 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.
FOR MODEL 125-RN (FOR USE
WITH NATURAL GAS ONLY)
Piping must be clean and free from scale or burrs.
Install regulator supplied with heater. Connect with
1/2" NPT nipple to control valve.
Connect the appliance to an appropriately designed
and installed fuel supply system. This system must
include an approved manual shutoff valve which
is readily accessible and is located within 6 feet
of the appliance. Additionally, a sediment trap or
drip leg must be located upstream of this manual
shutoff valve. Refer to the appropriate (natural gas)
installation code noted above. If a flexible connec-
tor is used, it must be of an approved type.
WARNING: Never use a flame
for gas leak testing.
