WARNING!
If you do not follow the instructions in this manual 
exactly, a fire or explosion may result causing 
property damage, personal injury or loss of life. 
For your safety, read this entire manual before 
installing or operating the GTS humidifier.
A.  This appliance does not have a pilot. It is equipped with an 
ignition device which automatically lights the burner. 
Do NOT try to light the burner by hand.
B.  Before operating, smell all around the appliance area for 
gas. Be sure to smell next to the floor because gas can be 
heavier than air and settle on the floor.
IF YOU SMELL GAS
  •  Do not try to light any appliance.
  • Do not touch any electrical switch; do not use any 
phone in your building.
  •  Immediately call your gas supplier from an off-site 
phone. Follow the gas supplier’s instructions.

department.
C.  Do not use this appliance if any part has been under water. 
Immediately call a qualified gas appliance service technician
