INSPECTION ITEMS
• Proper
fi eld operation of burner. Measure CO ppm, CO
2
%, O
2
%, fl ue temperature, and burner effi ciency at 100%
demand with the tank at a boil. Verify that measurements are within the guidelines described in burner tuning.

WARNING
Shutdown procedure:
Perform the shutdown procedure on page 15 before proceeding.
• Inspect
fl ue passageways external to the appliance, such as vent connector and chimney. Make sure they are clear
and free of obstructions.
• Ensure that vent connector is in place, sloping upward, and physically sound without holes or excessive corrosion.
• Ensure that physical support of the humidifi er is sound without sagging, cracks, or gaps between fl oor stand or tank
fl anges.
• Ensure that there are no obvious signs of deterioration of the humidifi er.
RO/DI WATER QUALITY RECOMMENDATIONS
• Verify regularly that water processing equipment is operating correctly. The presence of chlorides in improperly
processed DI water can cause pitting and failure of the tank and heat exchanger.
• GTS humidifi ers with the RO/DI water option do not require regular cleaning, although regular inspections are
advised.
• GTS humidifi ers with the RO/DI water option do not require skimming or draining and fl ushing to remove
precipitated minerals. However, at the end of a humidifi cation season, drain the humidifi er either by manually
opening the drain valve. If the humidifi er was purchased with end-of-season drain, it is already programmed to
drain.
