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 HS125NG, MH125LP, and HS125LP), and with the (U.S) Standard for the Storage and Handling of Liquefied Petroleum Gases, ANSI/NFPA 58 (for LP Gas operation, Model MH125LP, HS125LP), 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 MH125LP/HS125LP 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 MH125LP/HS125LP), 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-Gas container and must not be directed toward any 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 MH125LP/HS125LP (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 MH125LP/HS125LP 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.
