Locating Heater, Piping | Desa 125-RN manual

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.
