Cleaning and Care
Notices

2. Never use oven cleaner to clean any part of heater.
3. Do not clean any heater part in a self cleaning oven. The extreme heat will damage
the finish.
4. 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.
5. 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.
6. Inspect heater before each use.
7. Have heater inspected annually and repairs should be made by a qualified service
person.
8. 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.
Note: At temperatures less than 40ºF, heat output will be reduced.
c. Heater’s glow is excessively uneven
d. Burner makes popping noises during use.
Note: A slight pop is normal when burner is extinguished.
9. Carbon deposits may create a fire hazard. Keep dome and emitter clean at all times.
10. Do not clean heater with combustible or corrosive cleaners. Use warm, soapy
water.
11. Do not paint engine, engine access panel or dome.
12. This heater should be thoroughly cleaned on a regular basis.
13. After a period of storage and/or nonuse, check for leaks, burner obstructions and
inspect for any abrasion, wear, cuts to the hose.
Cleaning Surfaces
1. Wipe surfaces clean with mild dishwashing detergent or baking soda.
2. For stubborn surfaces use a citrus based degreaser and a nylon scrubbing brush.
3. Rinse clean with water.
Note:
While cleaning your 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.
Maintance
To enjoy years of outstanding performance from your heater, make sure you perform the following
maintenance activities on a regular basis:
1. Keep exterior surfaces clean.
2. 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.
TIP:
Use high-quality automobile wax to help maintain the appearance of your heater. Apply to
exterior surfaces from the pole down. Do not apply to emitter screen or domes.
Storage

1. Turn Control Knob OFF.
2. Disconnect LP source.
3. Store heater upright in an area sheltered from direct contact with inclement weather
(such as rain, sleet, hail, snow, dust and debris).
4. If desired, cover heater to protect exterior surfaces and to help prevent build up in air
passages.
Note:
Wait until heater is cool before covering.
During periods of extended inactivity or when transporting:
1. Turn Control Knob OFF.
2. Disconnect LP source and move to a secure, well-ventilated location outdoors.
3. Store heater upright in an area sheltered from direct contact with inclement weather
