SAFETY CHECK
OPERATION INSTRUCTIONS

Checking for Leaks
Your patio heater has been checked at all factory
connections for leakage. To check the connection at the
gas hose/regulator/cylinder:
a. Make leakage solution by mixing 1part liquid dish soap
and 3 part water.
b. Spoon or brush several drops (or use squirt bottle) of
the solution onto the gas hose/regulator and regulator/
cylinder and hose connection.
c. Turn on gas cylinder valve. Inspect the connections and
look for bubbles.
d. If no bubbles appear, the connection is safe.
e. If bubbles appear, there is leakage. Loosen and re-
tighten this connection.
Lighting Instructions
1. Ensure that the LP gas tank valve is OFF.
2. Push the control knob in, turn to OFF, and wait 5 minutes for any
gas to clear.
3. Turn the LP tank valve ON.
4. Push control knob in and slowly rotate to HIGH. This will activate
the built-in igniter and light the burner. Once burner is lit, hold control
knob in for 30 seconds and then release. If the burner fails to remain
lit or becomes extinguished, repeat step 4 before attempting to
relight.
5. Turn the control knob from LOW to HIGH to the desired heat
setting.
For complete shutdown
1. Please turn the knob to LOW first, then push and turn to OFF for
complete shut off.
2. Turn the LP gas tank valve OFF before removing the LP gas tank.
If you experience any ignition problem, turn off the heater and gas
supply, and consult “Troubleshooting” on page 16.
Visually check the burner flame against the illustrations below:
Flame should be blue with slight yellow tips.
You should see a smaller flame in LOW position than seen on HIGH.
Perform flame check prior to each use. If only low flame is seen, refer
to “Burner flame is low” in the “TROUBLESHOOTING” on page 14.

OPERATION INSTRUCTIONS
CARE AND MAINTENANCE
In any case of failure of normal ignition, please use a Lighter gun
(Sold Separately) to reach the burner for ignition through the hole on
the bottom of burner diffuser.
WARNING
FOR YOUR SAFETY:
If at any time you are unable to light burner and smell gas, wait 5
minutes to allow gas to dissipate before attempting to light heater.
WARNING
FOR YOUR SAFETY:
DO NOT touch or move heater for at least 45 minutes after use.
Allow emitter and dome to cool before touching.
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.
• Abrasive cleaners will damage this product.
• Never use oven cleaner to clean any part of heater.
• Do not clean any heater part in a self-cleaning oven. The extreme heat will damage the finish.
• More frequent cleaning may be required as necessary. It is imperative that control
compartment, burners and circulating air passageways of the heater be kept clean.
• Spiders and insects can create a dangerous condition that may damage heater or make it
unsafe. Keep burner area clean of all spiders, webs or insects. Clean burner holes by using a
heavy-duty pipe cleaner. Compressed air may help clear away smaller particles.
• Inspect heater before each use.
• Have heater inspected annually and repairs should be made by a qualified service person.
• Check heater immediately if any of the following conditions exist:
a. The smell of gas in conjunction with extreme yellow tipping of burner flames.
b. Heater does not reach proper temperature.
c. Heater’s glow is excessively uneven.
d. Burner makes popping noises during use.
Note: A slight pop is normal when burner is extinguished.
• Carbon deposits may create a fire hazard. Keep dome and emitter clean at all times.
• Do not clean heater with combustible or corrosive cleaners. Use warm, soapy water.
• This heater should be thoroughly cleaned on a regular basis.
• After a period of storage and/or no use, check for leaks, burner obstructions and inspect for
any abrasion, wear, cuts to the hose.

CARE AND MAINTENANCE
13
Cleaning
• Wipe surfaces clean with mild dish detergent or baking soda.
• For stubborn surfaces use a citrus-based degreaser and a nylon scrubbing brush.
• Rinse clean with water.
Note: While cleaning the unit, be sure to keep the area around the burner and pilot assembly
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.
TIP: Use high-quality automobile wax to help maintain the appearance of the heater. Apply to
exterior surfaces from the pole down. Do not apply to emitter screen or domes.
Maintenance
• Keep exterior surfaces clean.
• Air flow must be unobstructed. Keep controls, burner and circulating air passageways
clean.
Signs 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.
Note: In a salt-air environment (such as near an ocean) corrosion occurs more quickly than
normal. Frequently check for corroded areas and repair them promptly.
Storage
Between uses or during periods of extended inactivity:
• Turn control knob to “OFF”.
• Disconnect LP cylinder and move to a secure, well-location outdoors.
• Store heater upright in an area sheltered from direct contact with inclement weather (such
as rain, sleet, hail, snow, dust and debris).
Note: Never leave LP gas tank exposed to direct sunlight or excessive heat.
• If desired, use cover (Sold Separately , Model Number CHC-301) to protect the heater and
help prevent buildup in air passages.
CAUTION: Wait until heater is cool before covering.
