Humidifier De-scaling Solution
Scale buildup on humidifier heat exchangers
acts as an insulator, reducing humidifier
performance while increasing energy costs.
To keep humidifiers operating as efficiently
as possible, remove scale with DriSteem's
Humidifier De-scaling Solution, available for
purchase from your DriSteem representative or
distributor.
The De-scaling Solution cleans without risk
of corroding humidifier tanks or welds. The
De-scaling Solution also cleans surfaces
unreachable by hand scraping.
DriSteem's Humidifier De-scaling Solution is the
only approved cleaner/de-scaler for use with
DriSteem humidifiers. Use of other cleaners/de-
scalers may void your DriSteem warranty.

INSPECTING BURNER ASSEMBLIES AND HEAT EXCHANGER TUBES
This is not a regular maintenance item, but if the heat exchanger tubes contain
carbon deposits, soot, or other residue, clean as follows:
1. Turn off gas, electrical power, and water supply.
2. Remove gas train shroud.
3. Disconnect wiring to blowers, flame sensors, gas valves, and ignition
controllers and remove burner assemblies (each assembly is mounted with
four bolts).
4. Remove vent box.
5. Use a 6" (150 mm) flue brush with a 24" (600 mm) extension and
reversible drill. Work brush in and out of all combustion chambers.
Note: Disconnecting components from one burner assembly at a time and
then cleaning the corresponding combustion chamber and burner will
ease reassembly.
6. Remove loose deposits and residue that falls into rear header with a
vacuum cleaner and hose extension.
7. Inspect 1½" (DN40) return tubes and clean if necessary.
8. Run thin brush between turbulator and tube wall on all four sides.
9. Reinstall burner assemblies and gaskets; vent box and gasket; all electrical
wiring; gas train shroud; and pressure switch connections.
BURNER MAINTENANCE
Under normal use conditions, the burner(s) should not need cleaning for a
minimum of five years. However, depending on the operating environment,
the burner(s) may require periodic cleaning to remove accumulated materials.
Failure to clean burners can result in reduced unit capacity. Use sealed
combustion in dirty environments. See burner maintenance instructions below.
BURNER MAINTENANCE INSTRUCTIONS
To service the burner system, clean both the blower and the burner. Remove the
blower(s) from the system and clean dust from the wheel. Remove the burner(s)
for cleaning. Removing and cleaning one burner at a time eases reassembly.
To dislodge particulate matter from the burner surface matrix, use compressed
air (100 psig [700 kPa] maximum). Keep the air nozzle about 2" (50 mm)
from the burner's surface, blowing air perpendicular to the burner surface
while moving the nozzle back and forth lengthwise. This dislodges particles
trapped in the matrix, pushing them back inside the burner. Avoid blowing
air across the surface, which tends to have a destructive effect on the burner
surface. Allow particulate matter to fall from the burner through the air/gas
inlet. To assist in removing the particulate matter, use a vacuum at the burner's
air/gas inlet.
START-UP
Perform the Annual safety checks in the Inspection and maintenance section on
page 4.
If resuming operation after service, do not leave the humidifier unattended;
allow it to cycle through multiple fill cycles to verify that all serviced parts
are functioning properly. See the humidifier's Installation, Operation, and
Maintenance manual for start-up details.
DriSteem products are warranted according to the terms and conditions of
the standard two-year Limited Warranty effective when the humidifier was
purchased. See the literature that was shipped with the humidifier for warranty
information.
