by opening the circuit again. THE TIMER MAY ONLY BE
OPERATED AFTER IN TALLATION IN A PROTECTIVE
HOU ING. A large 3-digit LCD display is provided for
monitoring the countdown of the timer.

3. STEAM VENT
IMPORTANT: A steam vent (PN 104072)must be installed in the
steam line between the steam generator and the steam solenoid
valve when using a 30 minute timer as shown. The steam vent will
release hydrostatic pressure in the boiler while filling when the 30
minute timer has timed out.
Make sure the boiler and pipes are not hot and
have no pressure before installing the steam vent.
1. The steam vent shall be plumbed into a Tee in the steam line
between the boiler and the solenoid valve. Only one steam vent
is required, even if the boiler services two rooms.
2. IMPORTANT NOTE: The steam vent should remain accessible for
service.
3. The steam vent should be
oriented vertically, with the
threads down, as shown in
Figure 4.
4 . The steam vent is provided
with 3/4" NPT male and
1/2" NPT female thread
for connecting to the
steam line.

Using the “–” and “+” buttons, you can set the desired running
time during which the steam generator will operate, press the
“MODE ” button. The steam solenoid connected to the timer is

while the colon in the center of the time display flashes.
END OF RUNNING TIME
After the preset running time has elapsed, the timer
switches the connected steam solenoid off issuing short
beeps (for up to 15 seconds). The value 0:00 is shown on the
display, and the colon stops flashing.
