Nevertheless, all burner safety controls
should be checked upon installation, prior to
initial firing. Failure to verify burner control
functioning could result in severe bodily
injury or death.
For detailed procedures on how to test the
safety controls, see the boiler Operation and
Maintenance Manual.
1.7 Filling Boiler
Ensure that all feedwater equipment is properly installed and any feed
pumps, valves, etc. are in good working order.
Begin with the control panel DEMAND switch and the CC-BLOWER
switch (see Figure 8) in the OFF position. Open the boiler vent valve
(see Figure 9).
Turn the Control Circuit/Blower Switch ON to enable the feedwater
control circuit. If the CB Falcon icon does not appear on the display
when the CC/Blower switch is turned on, see STARTING THE
BOILER below.
With the vent valve open, entrapped air will be allowed to escape
while the boiler fills with water. Do not close the vent valve until water
is visible in the gauge glass. The feed pump will shut off when water reaches the 'Pump Off' probe level.
Check to ensure that no leaks appear at any pipe connections and correct if water leaks are noticed.
The use of soft water is highly recommended. Failure to observe this recommendation can lead to dangerous operating conditions,
and may result in damage to the boiler. If necessary, your Cleaver-Brooks representative can provide additional information
regarding your water softening requirements.
