After all burners have failed to ignite, the fault message "No Burners Available" will appear on the
display. The blowers will perform a post-purge and then shut off.
5. Power cycle the humidifier to reset the fault condition.
6. Open the manual gas shutoff valve.
5.2.3 Starting the Humidifier
Start the humidifier as follows:
1. Make sure that the tank in the humidifier is filled with water – refer to "Filling the System" on page 41 .
2. Make sure that the ignition safety shutdown test is completed – refer to "Ignition Safety Shutoff Test" on
page 41 .
3. Check that the shutoff valve in the water supply line is open.
4. Check that the manual gas shutoff valve in the supply line is open
5. On the CS model, make sure that the condensate trap inside the unit is primed properly.
6. Check that the contacts of all devices connected to the external security loop are closed.
7. Make sure that all access panels on the humidifier are installed and fastened securely.
8. Set the On/Off button on the humidifier to the On position.
The control software then energizes the dual fill valve(s) and starts to fill the tank. It then performs
a series of tests to verify the function of the floats, the dual fill valves and the drain pump – refer to
"Water Management" on page 13 . Upon successful completion of the tests, the combustion sequence
starts – refer to "Combustion" on page 12 .
Depending on the system demand, the blower(s) runs faster or slower to control the input of the
burner(s). The generated heat turns the water in the tank to steam, which is then delivered to the
distribution system.
As the water level in the tank is reduced due to evaporation, the dual fill valves pulse to maintain
water at the proper level. In the CS model only, cold fill water passes through the secondary heat-
exchanger. Here, heat from the exhaust warms up the cold fill water entering the tank before entering
the fill box. The water will then flow from the fill box into the tank.
When the humidity demand has been satisfied (demand drops below the minimum %), the gas
valve(s) is de-energized. The blower(s) then performs a post-purge of the combustion chamber(s),
and then shuts off.
If there is no humidity demand, the humidifier goes into standby mode to await the next humidity
demand signal.
