Mount the exhaust line in place with the supplied brackets and make sure 
that it is secure to withstand vibrations.   

 

When fastening the exhaust line to the heater apply 
exhaust paste on the end of the tube and around the 
outside of the exhaust fitting on the heater.  Push 
the exhaust line into place and fasten with the 
heavy-duty clamp supplied with the unit.  When 
tightening the clamps keep in mind to leave room for 
the fuel connection.  

Caution!  

Risk of injury: The end of the exhaust pipe is extremely sharp and can 
easily cut through skin.  Use gloves when cutting and mounting the 
exhaust line.  

Warning! 

The burning process inside the heater produces high temperature toxic 
gases, therefore the exhaust tube must be installed according to the 
instructions given  

 

Do not perform any maintenance or work on the unit or exhaust 
system when the heater is running. 

 

Before doing any work on the heater switch the unit off and wait until 
all the parts have cooled down.  

 

Do not block or cover the exhaust outlet when the heater is in 
operation. 

 

The exhaust system must vent straight to open atmosphere. 

 

Do not operate the heater in closed spaces where the exhaust is not 
exiting to open atmosphere.    

 

Do not point the exhaust outlet in the direction of travel. 

 

Do not connect the exhaust to other exhaust systems.  

 

Exhaust lines must be routed in a way that avoids potential human 
contact.  

 

Adequate distance must be allowed between the exhaust lines and 
any heat sensitive or flammable materials.
