2583703_EN_1608
Drainage
The humidifier should be connected to a dedicated building drain (recommended) with a minimum
drainage rate of 5.3 gpm (20 L/min). The drain line must allow free and easy drainage.
The building drain pipe should be made of either copper or stainless steel (minimum DIN 1.4301) to
handle discharge water at up to 212 °F (100 °C).
The space in which the humidifier is to be installed should have a floor drain connected to the build -
ing drain. However, if a floor drain is not available, a leakage monitoring device must be supplied
to permit interruption of the water supply in case of a leakage. A drain pan is also recommended to
prevent property damage.
Combustion Air
The space in which the humidifier is to be installed must have access to a good supply of clean
combustion air at atmosheric pressure. Adhere to appropriate local and national installation regula -
tions for sealed combustion and space air installations.
The maximum temperature of the combustion air supply should be 86°F (30°C).
For additional requirements for sealed combustion and space air installations refer to "Combustion Air
Connection" on page 40 .
Exhaust Venting
The space in which the humidifier is to be installed must permit routing of exhaust air to the outside.
Adhere to all local and national installation regulations.
For additional requirements for the different types of exhaust vent installations refer to "Exhaust Vent
Connection" on page 43 .
Gas Supply
Gas supply to the unit must be equipped with a certified manual gas shutoff valve located in the
immediate vicinity of the humidifier.
If black pipe is used, a sediment trap (located between the manual shutoff valve and the unit) must
also be supplied.
A capped 1/8 in NPT test port must be supplied in the gas line immediately upstream from the hu -
midifier gas connection.
A union fitting must be supplied in the gas line immediately upsteam from the humidifier gas connection.
The operating pressure of the gas supply to the humidifier must be as listed in
Table 7
.
Table 7: Gas Operating Pressure
Gas Type Operating Pressure
Minimum Maximum
Natural gas (North America) 5 in H2O (1.25 kPa) 10.0 in H2O (2.49 kPa)
Propane (North America) 9.0 in H2O (2.24 kPa) 14.0 in H2O (3.49 kPa)
The gas supply line must be sized as listed in
Table 8
. The pipe connection should have male NPT
threads.
