LOCATING HEATER FOR USE
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.

STORAGE BURNER REMOVAL
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.
CLEANING:
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).
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.

To enjoy years of outstanding performance from your heater, make sure you perform the following
maintenance activities on a regular basis:
• Keep exterior surfaces clean
• Use warm soapy water for cleaning. Never use flammable or corrosive cleaning agents.
• While cleaning you unit, be sure to keep the area around the burner dry at all times. Do not submerge
the control valve assembly. If the gas control is submerged in water, do NOT use it. It must be
replaced
• Air flow must be unobstructed. Keep controls, burner, and circulating air passageways clean. Sign of
possible blockage include:
Gas odor with extreme yellow tipping of flame
Heater does NOT reach the desired temperature
Heater glow is excessively uneven
Heater makes popping noises
• Spiders and insects can nest in burner or orifices. This dangerous condition can damage heater and
render it unsafe for use. Clean burner holes by using a heavy-duty pipe cleaner. Compressed are may
help clear away smaller particles.
• Carbon deposits may create a fire hazard. Clean dome and emitter with warm soapy water if any
carbon deposits develop
Noted: In a salt-environment (such as near an ocean), corrosion occurs more quickly than normal.
Frequently check for corroded areas an repair them promptly.
BURNER INSTALLATION
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.

MAINTENANCE
BEWARE
OF SPIDERS
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 .
