carbon monoxide. WARNING! Risk of indoor air pollution! Use 
this heater only in well ventilated areas! Provide at least a 2,800 
sq cm opening of outside air for every 29,3 kw/hr or 100,000 BTU/
hr of heater rating. Provide a larger opening if more heaters are 
being used.
Risk of burns / fire / explosion! NEVER 
use fuel such as gasoline, benzene, alcohol, 
white gas, camp stove fuel, paint thinners, or other oil compounds 
in this heater (THESE ARE VOLATILE FUELS THAT CAN 
CAUSE A FIRE OR EXPLOSION).

Assembly
1. Attach handle by lining up holes of handle with the holes 
in the upper shell of heater (See fig. 1).
2. Insert screws and tighten.
Ventilation
ALWAYS provide a fresh air opening in the heated space 
of at least 2,800 sq.cm for each 29 Kw/Hr. of heater 
output. Provide a larger opening if more heaters are being 
used. 
Fueling the Heater
Never fill the fuel tank indoors. Always fill the tank 
outdoors. Be sure that the heater is on level ground 
when fueling, and never overfill the fuel tank.
It is always a good idea to fire the heater outdoors for the 
first time. This will allow any oils used in the manufacturing 
process to be burned off in a safe environment. This initial 
burn should last at least 10 minutes.
NOTE: On first ignition or after refueling, you may hear 
a grinding sound just before ignition.  This is the fuel 
pump removing air from the fuel line.  Your heater will 
start up within seconds.  If it does not start, repeat 
Step #4 with fuel gauge reading at least 1/2 tank.
