to support the combustion air require-
ments of the heater being used.
• Refer to the specification section of
the heater’s manual, heater data plate,
or contact DESA Heating Products to
determine combustion air ventilation
requirements of the heater.
• Lack of proper ventilation air will lead
to improper combustion.
• Improper combustion can lead to car-
bon monoxide poisoning leading to
serious injury or death. Symptom of
carbon monoxide poisoning can include
headaches dizziness and difficulty in
breathing.
1. Keep children and animals away from heater.
2. Never operate heater while sleeping or unat-
tended.
3. Check the heater thoroughly for damage. Do
not operate a damaged heater.
4. Do not modify the heater or operate a heater
which has been modified from its original
condition.
5. Use only propane/LP gas.
6. Use only vapor withdrawal propane/LP
supply. If there is any question about vapor
withdrawal, ask your propane/LP dealer.
7. For outdoor use only. Area must be well ven-
tilated. Provide minimum openings of 1 sq ft
(.093m²) near the floor and 1 sq ft. (.093m²)
near the ceiling. Do not use inside house,
camper, tent, vehicle, or any type of unvented
or enclosed area.

or hose is cut, replace with hose assembly listed
on parts list before using heater. The hose and
regulator must be protected from damage.
12. The heater burner must be at least 2 ft. (.61m)
above the floor. Always attach to propane/LP

to dangerous flare-ups or fire. Do not direct
heat toward propane/LP cylinders.
13. Maintain minimum clearance from nor-
mal combustible materials (like paper)
as follows: Sides - 3 ft. (.91m);
Top and
Front - 5 ft. (1.5m). Locate 10 ft. (3m) from
