SAFETY WARNINGS 

 
The Troxler NTO Asphalt Content Ignition Oven is a safe, durable 
unit. Troxler cannot anticipate every example of improper or 
unauthorized use of this oven that may lead to malfunction or 
accident. If a particular use is 

not specifically mentioned

 in this 

manual as authorized, then assume that the use is unauthorized and 
improper. 
 
Always follow the safety warnings in this manual and the safety 
procedures of your laboratory/company. Refer to the MSDSs 
provided with each oven for further safety information. Troxler 
recommends the following safety precautions. 
 

READ ALL INSTRUCTIONS CAREFULLY 

 

 

The installation of the oven must comply with local building 
code rulings. 

 

Troxler recommends the installation of a carbon monoxide 
detector. 

 

Keep the area around the oven clear and free from all 
combustible materials, gasoline, and other flammable vapors 
and liquids. Failure to do so could cause fire or explosion. 

 

Place the oven on a level, sturdy, fireproof surface. 

 

The ambient temperature should be between 10 and 50 

°

C (50 

and 122 

°

F), and the relative humidity should be less than 92%. 

 

Allow at least 15 cm (6 in.) between the oven and other vertical 
structures. 

 

During normal operations, the chamber door cannot be opened 
during a burn cycle. However, if the door lock should fail or be 
defeated by the operator, it may be possible to open the door 
while combustion is occurring inside the oven. If this should 
happen, flames may exit from the top of the door. Therefore, 
there must be at least 91 cm (3 ft) of clearance above the oven. 

 

Locate the oven 

no more than

 1.2 m (4 ft) from the required 

electrical power source (see Appendix C). Ensure that the 
distance does not place stress on the power cord. The power 
source must be wired by a qualified electrician.
