2Maintenance schedule

Check air vents

1.Reference FIG. 3 below.

2.Visually inspect vent to make sure that no leaks are present.

3.If there is leaking, tighten the needle valve.

4.If the leak continues, replace the air vent.

Figure 2-3 Air Vent

￿WARNING Have leaks fixed at once by a qualified service technician. Failure to comply could

result in severe personal injury, death, or substantial property damage.

3.Replace the front access door.

Operate relief valve

1.Before proceeding, verify that the relief valve outlet has been piped to a safe place of discharge, avoiding any possibility of scalding from hot water.

VALVE

Test low water cutoff (if installed)

1. If the system is equipped with a low water cutoff, test the

low water cutoff periodically during the heating season,

following the low water cutoff manufacturer’s

￿WARNING

To avoid water damage or scalding due to valve operation, a metal discharge line must be connected to the relief valve outlet and run to a safe place of disposal. This discharge line must be installed by a qualified heating installer or service technician in accordance with the instructions in the Knight Wall Mount Installation and Operation Manual. The discharge line must be terminated so as to eliminate possibility of severe burns or property damage should the valve discharge.

instructions.

Reset button (low water cutoff)

1.Testing the low water cutoff shuts the unit off. Press the RESET button on the low water cutoff to turn the unit back on.

Check boiler piping (gas and water)

1.Remove the boiler front access door and perform a gas leak inspection per steps 1 through 7 of the Operating Instructions on pages 9 and 10. If gas odor or leak is detected, immediately shut down the boiler following the procedures on pages 9 and 10. Call a qualified service technician.

2.Visually inspect for leaks around water piping. Also inspect the circulators, relief valve, and fittings. Immediately call a qualified service technician to repair any leaks.

2.Read the boiler pressure/temperature gauge to make sure the system is pressurized. Lift the relief valve top lever slightly, allowing water to relieve through the valve and discharge piping.

3.If water flows freely, release the lever and allow the valve to seat. Watch the end of the relief valve discharge pipe to ensure that the valve does not weep after the line has had time to drain. If the valve weeps, lift the seat again to attempt to clean the valve seat. If the valve continues to weep afterwards, contact your qualified service technician to inspect the valve and system.

4.If water does not flow from the valve when you lift the lever completely, the valve or discharge line may be blocked. Immediately shut down the boiler, following the operating instructions on pages 9 and 10 of this manual. Call your qualified service technician to inspect the boiler and system.

Shut boiler down (unless boiler is used for Domestic Water)

1.Follow “To Turn Off Gas to Appliance” on pages 9 and 10 of this manual.

2.Do not drain the system unless exposure to freezing temperatures will occur.

3.Do not drain the system if it is filled with an antifreeze solution.

4.DO NOT shut down boilers used for domestic water heating, they must operate year-round.
