Is the surrounding area free of combustible materials, gasoline and other flammable vapors or liquids?

For your safety, if re-lighting a hot heater. Always wait at least five (5) minutes.

(A) Open tank enclosure door.

(B) Make certain hose is connected to the heater intake hose and regulator is connected to the propane tank. Check both connections to ensure they are tight and leak proof.

(C) Turn supply tank valve in a counter clockwise direction. Check for leaks by applying soapy water to the tank and hose connections.

(D) Push and slowly turn the gas control knob to the “IGNITE/HI” position (see diagram below).

Keep pushing the knob for 3-5 seconds until the heater stays lit. Select the desired heat level by adjusting the knob from “IGNITE/HI” to “LO” after the heater is lit.

(E) If ignition does not occur, push and turn the knob to the “OFF” position and repeat step “(C)” up to 3 times.

(F) If ignition still does not occur, push and turn the knob to the “OFF” position, wait 5 minutes for the accumulated gas to dissipate, and then repeat steps D and E.

CAUTION : Avoid inhaling fumes emitted from the heater’s first use. Smoke and odor from the burning of oils used in manufacturing will appear. Both smoke and odor will dissipate after approximately 30 minutes. The heater should NOT produce thick black smoke.

12

WHEN HEATER IS ON:

� The emitter screen will become bright due to intense heat. The color is more visible at night.

� The burner will display tongues of blue flame. These flames should not be all yellow or produce thick black smoke, indicating an obstruction of airflow through the burners. The flame should be blue with straight yellow tops.

� The flame pattern at the emitter grid should be visually checked whenever heater is operated (see figure 1). If flames extend more than 1/2 inch (12.7mm) beyond surface of the emitter grid or reflector the heater should be turned off immediately and the heater should not be operated again until repairs are made.

C AUTION : This patio Heater contains a Tilt Safety Switch which is designed to provide safe use of the patio heater. The tilt safety switch will automatically shut-off the heater when it tilts in the tip angle over 45-60 degrees from vertical position.

13

WHEN STORING THE HEATER THE CONNECTION BETWEEN THE PROPANE TANK

AND THE HEATER MUST BE DISCONNECTED AND THE PROPANE TANK REMOVED

FROM THE ENCLOSURE AND STORED OUTDOOR IN A WELL VENTILATED AREA

OR IN ACCORDANCE WITH CHAPTER 5 OF THE STANDARD FOR THE STORAGE

AND HANDLING OF LIQUEFIED GASES, ANSI/NFPA 58-1998.

Your heater will last longer if maintained properly. It is important that the flow of combustion air must never be obstructed. Orifice and air openings must be kept free of dirt and spider webs. Never use a cleaning agent which is flammable or corrosive.

It is recommended that the heater body components; from the burner head down, are periodically protected with a coat of automobile wax .

If repainting is necessary, paint only the post/base assembly. Never paint the reflector, emitter assembly the safety control valve cylinder, valve panel or instruction plate on post.

The posts of the burner must remain clean so that the gas flow is unrestricted. The air inlet of the venture tube must also be kept clean for combustion air supply if the heater is not performing properly it may be necessary to clean the burner (see burner removal).

1. Remove reflector and emitter assembly by removal of the screws that fasten the emitter assembly to the lower screen cone .

2. Remove the burner by unscrewing the burner from the top of the valve body.

Any debris in the opening of the burner assembly can be cleared with a straightened piece of coat hanger. Any rust can be removed carefully with a wire brush. Never use a piece of wood or other materials that might break off and block the ports.

Caution: Bugs and small insects easily get into the burner, gas orifice. Check the unit before using after extended storage.

Tips: Lighting the Patio Heater once a month will ensure your heater remains in good working condition.

14

BURNER INSTALLATION

Install the burner assembly by reversing the four (4) steps used for disassembly making certain the burner assembly stands centered when complete.

After reassembly, the heater should be test fired. Observe the burner flame. The flame should be blue with a slight yellow tipping.

CAUTION : BURNER TUBES MUST BE INSPECTED AND

CLEANED BEFORE FIRST USE

Spiders and small insects occasionally spin webs or make nests in the burner tubes and orifices during warehousing and transit.

These webs or nests can lead to a gas flow obstruction which could result in a fire on or around the burner tubes. This type of fire is known as FLASH BACK and can cause serious damage to your patio heater and create an unsafe operating condition for the user.

Although an obstructed burner tube is not the only cause of

FLASH BACK it is the most common cause and frequent inspections and cleaning of the burner tubes is necessary .
