Never use tools. If the knob will not push in or turn by 

hand, do not try to repair it, call a qualified service 

technician. Force or attempted repair may result in a 

fire or explosion.

 

 

These unit heaters are equipped with an automatic 

spark ignition system. There is no pilot. In case of a 

safety shutdown, move thermostat switch to 

OFF

, then 

return the thermostat switch to HEAT position.
