6.1.11 Pressure Gauge Inspection

• Make sure the pressure reading on the heater pressure gauge (item “M” in Figures 5-1

or 5-3) does not exceed the maximum working pressure. Higher pressures may indicate
a problem with the expansion tank.

Contact a qualified service technician if problem persists.

6.1.12 Condensate Drain System Inspection

• Inspect the condensate drain line, c

ondensate fittings, and condensate trap for signs of

weeping or leakage.

• If you detect signs of leakage,

immediately contact your qualified service technician to

inspect the boiler and system.

• Ensure there is sufficient neutralizer media. It is recommended to replace this media

annually.

WARNING!

Have leaks fixed at once by a qualified service technician.

6.1.13 Low Water Cutoff Test

If an LWCO is installed, it should be tested. Testing the low water cutoff shuts the unit off. Press
the RESET button on the low water cutoff to turn the unit back on.

6.1.14 Flow Switch Test

If a flow switch is installed, test it for correct operation. Remove the switch cover and manually
toggle the switch. Ensure that it moves freely and causes a fault condition in the unit.
