Space-Ray ADU25 Installation And Operation Instruction Manual page 4

This heater is not an explosion proof heater. Where the possibility of exposure to volatile and low flash point
materials exists, it could result in property damage or death. This heater must not be installed in a spray booth
where the heater can operate during the spraying process. Consult your local fire marshal or insurance company.
Linear Configuration Series Only: Since linear configuration tube heaters are always hotter at the control end
than at the flue terminal end, always observe the minimum recommended mounting heights.
