use of this heater can cause serious injury.
2. For outdoor use only. Do not use inside house, camper, tent, vehicle, or any type of
unvented or enclosed area.
3. Never operate heater while sleeping or unattended. Keep children and animals
away from heater.
4. WARNING: This product contains and/or generates chemicals known to the
State of California to cause cancer or birth defects, or other reproductive harm.
5. Minimum heater clearances from combustibles:
Top and Front: 5 Ft. Sides and Rear: 3 Ft.
6. Use only in well-vented areas.
7. Use only propane gas set up for vapor withdrawal.
8. Before connecting heater to propane tank, make sure heater regulator knob is in
the "OFF" position. Always connect and light heater in areas free of open flames.
9. Before each use, check heater for leaks. Never use an open flame to check for a
leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a
leak. Correct all leaks at once.
10. Locate propane tank on a stable and level surface. The heater burners must be at
least two feet above the floor. Always attach heater to propane tank in an upright
position. Never operate heater on its side or attach to propane tank in a horizontal
position. This could lead to dangerous flare-ups or fire.
11. Do not use heater in basement or below ground level. Propane is heavier than air. If
a leak occurs, propane gas will sink to the lowest possible level. If you smell gas or
suspect a leak, shut off the propane tank valve at once and ventilate the area. Do
not strike match or create any flame or electric spark. Find and correct leak before
attempting to light any appliance. If you cannot correct leak, do not tamper with
heater. Return heater to nearest authorized service center or to address on back
page of this manual, freight prepaid.
12. Do not move or handle a hot or operating heater. Do not attach or remove a
propane tank from a hot or operating heater. Severe burns may result.
13. Always remove heater from propane tank after each use. Always store propane
tank outdoors. Never store propane tank in an enclosed area. Never store propane
tank near high heat, open flame, or where temperatures exceed 100
14. Keep all connections and fittings clean. Make sure propane tank valve outlet is
clean. Check the "O" ring on the heater inlet fuel connector for damage before each
use. Replace if worn or damaged.
15. Do not attempt to light one burner off of the other. Use one match per burner.
16. Do not overlap or point burners at each other.
17. Do not raise burner heads and cover air inlet holes in mixing tube with burner
head bracket.
18. Wing nuts and burner heads become very hot during operation. Do not attempt to
adjust burner position while heater is operating. Allow 15 minutes to cool.
19. Check heater for damage before each use. Do not use a damaged heater. Do not
alter heater. Keep heater in its original state. Do not use heater if altered.
