Mr. Heater MH35LPTS Operating Instructions, LIGHTING AND SHUT-DOWN Lighting the Heater

The connection of Model MH35LPTS 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/NF-PA 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.

Piping must be clean and free from scale or burr.

Before attempting to ignite the appliance, all gas fittings and connections must be thoroughly checked for gas leaks. Apply a small amount of a mild soap and water solution to all fittings and connections and observe for escaping bubbles. If any leaks are detected, shut off the gas supply to the appliance immediately. Wait a minimum of five minutes, repair the leak(s) and retest for leakage. Dry all fittings and connections after leak testing.

WARNING

NEVER USE A FLAME FOR GAS LEAK TESTING.

LIGHTING AND SHUT-DOWN

Lighting the Heater:

1.Before attempting to light the heater, smell all around the heater area for gas. Be sure to smell next to the floor because LP-Gas is heavier than air and will settle on the floor. Turn on the gas supply to the appliance and check all fittings and connections for gas leaks using a mild soap and water solution. NEVER use a match to check for gas leaks. Should a gas leak occur, shut off the gas supply to the appliance immediately. Wait a minimum of five minutes before repairing the leak.

2.Use only the fuel intended for this appliance. Check the appliance rating plate for the correct fuel information.

3.Turn off the main gas supply to the appliance. Wait five minutes.

4.Turn on the main gas supply.

5Depress red spark ignition button repeatedly or with a lighted match held to the burner face, depress and hold the reset button on the safety valve. After the burner ignites, hold the reset button depressed for about one minute or until the burner stays lit when the reset button is released. DO NOT light the gas at the burner orifice. DO NOT face heater when attempting to light. Always stand to the side of the unit when lighting.

NOTE: In cases where long runs of gas supply lines have been installed ahead of the appliance, it may be necessary to bleed trapped air out of the supply lines before lighting the burner. New installations generally require bleeding of supply lines. Wait a minimum of five minutes after bleeding the supply lines before attempting to light the heater.

6.IMPORTANT: DO NOT attempt to adjust the main burner input using the main gas supply valve, for this may cause the thermocouple to shut down the burner.
