surance or local codes require, go to a "lockout” mode. Lockout will require manual reset of the flame safeguard.

4.After completing this test, turn off the boiler and reconnect the wire to the main gas valve. Replace the control panel faceplate.

4.4.2 Test of Low Water Cutoff

The boiler is furnished with a flow-switch-type low water cutoff in the outlet nozzle.

1.Make sure the boiler is off.

2.Turn the system pump off, stopping water flow in the system. Do not shut the pump off while the boiler is operating.

3.Turn the boiler back on. It should not operate, and a red indicator for "Low Water" or "Water Flow" should be illuminated.

Perform appropriate tests on any external probe-type low water cutoff.

4.4.3 Test of High-Limit Control

The boiler is furnished with a high-limit cut off.

1.With the main burner operating, turn down the temperature setting on the "high-limit" thermostat until the main burner shuts off. The high-limit switch must be reset manually after testing.

This check should also be made for the "Operating Temperature" control. (The green "Heat" indica- tor will go out.) (See the “Installation and Owner’s Manual,” page 8 for Lo-Hi-Lo units.)

2.Readjust thermostats to desired operating tem- perature and set high-limit temperature, typically 20￿ F above operating temperature.

4.4.4Test of Gas Pressure Switch

Reset

Figure 4-6 Gas Pressure Switch

The boiler is furnished with a low gas pressure switch.

1.Slowly close the manual shutoff valve (on the natural gas supply) while the burner is operating. The low gas pressure switch should shut down the main burner before combustion problems are en- countered. When the gas pressure switch opens, the "Low Gas" or "Gas Press" indicator will illu- minate.

2.Reopen the manual shutoff valve. The "Low Gas" or "Gas Press" indicator should remain on until the low gas pressure switch is reset.
