VENTILATION
WARNING
THIS APPLIANCE IS UNVENTED AND MUST BE
USED ONLY IN A WELL VENTILATED AREA.
The flow of combustion and ventilation air must not be
obstructed. DO NOT use in a tightly enclosed area.
Any combustion process requires and consumes oxygen, and
may produce carbon monoxide. This heater must be operated
with adequate ventilation. Two openings directly to the outdoors
must be provided, one low and one high, preferably on opposite
sides of the area to be heated. Each of these openings must
provide at least three square inches of combustion air-intake area
and exhaust outlet area for every 1000 BTUs per hour of heater
input rate in order to complete the combustion/ventilation
process. Provide additional ventilation for any additional fuelburning appliances and/or additional occupants.
CLEARANCE (Minimum clearances to combustible materials)
Do not exceed the gas supply pressures shown on rating plates. The maximum inlet gas supply pressures and minimum inlet supply
pressures (for purposes of input adjustment) for LP-Gas and Natural gas are shown as follows:

INSTALLATION INSTRUCTIONS
GENERAL:
READ THESE INSTRUCTIONS CAREFULLY. Read and adhere
to these instructions. DO NOT allow anyone who has not
read these instructions to assemble, light, adjust or operate
this heater.
DO NOT attempt to operate the heater with any gas other
than that indicated on the heater nameplate.
For the U.S. and/or Canada, the installation of this appliance
must comply with local and/or Provincial codes or, in the
absence of these codes,
• With the (U.S.) National Fuel Gas Code, ANSI Z223.1 –
Latest Edition (for Natural and LP-Gas operation,
Models 125-RN, 125-R), and with the (U.S)
Standard for the Storage and Handling of Liquefied
Petroleum Gases, ANSI/NFPA 58 (for LP Gas
operation, Model 125-R), or
• with the current (Canadian) CAN/CGA B149.1 AND
B149.2 INSTALLATION CODES.
This heater (including hose and regulator assembly if applicable)
must be inspected before each use and at least annually by a
qualified service person. If the hose for Model 125-R shows
evidence of excessive abrasion or wear, or if the hose is
cut, it must be replaced prior to the heater being put into
operation. The replacement hose assembly shall be that
specified by the manufacturer. See the parts list.
LOCATION
The heater (and LP-Gas supply cylinder if applicable) must be
located on a hard, flat, level surface to minimize the risk of
accidental tipping. If an LP Gas supply cylinder is used (i.e. with
Model 125-R), 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 six feet away from any LP-Gascontainerand
ust not be directed toward any LP-Gas container within 20
feet.
Due to high surface and exhaust temperatures, adults and
children must observe clearances to avoid burns or
clothing ignition.
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 LP-Gas)
This model may be connected to a self-contained LP-Gas
supply system using the hose and regulator assembly
supplied with the appliance, OR, it may be connected to a
permanently installed LP-Gas supply system.
If connected to a self-contained 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.
If connected to a self-contained LP-Gas supply system,
the cylinder must have no less than a minimum
capacity of 20 pounds and no more than a maximum
capacity of 100 pounds of LP-Gas. DO NOT connect
this appliance to a cylinder having less than a nominal
20 pounds capacity of LP-Gas. DO NOT connect this
appliance to more than one (1) 100 pound cylinder.
WARNING
NEVER USE A FORK LIFT TRUCK TYPE
CYLINDER.
The connection of Model 125-R to an LP-Gas 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 LP regulator) to the LP-Gas cylinder.
Turn the POL nut in a counter-clockwise 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
LP-Gas cylinder and must not be directed toward any LP-Gas
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 LP-Gas supply
cylinder when the heater is not in use.
When the heater is to be stored indoors, the connection
between the LP-Gas 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 LP-Gas supply
system, the system requires the use of a two-stage
gas regulator assembly which is normally provided by
your LP Gas dealer as part of the LP-Gas supply
system. Consult with your local LP Gas dealer for
details concerning proper equipment and installation.
