GAS-FIRED WATER BOILER SERIES 2 — User’s Information Manual

Maintenance procedures (continued)

Periodically

Test low water cutoff (if installed)

Every 6 months

Check boiler piping (gas and water)

Operate relief valve

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 instructions.

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

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

Have leaks fixed at once by a qualifed service technician. Failure to comply could result in severe personal injury, death or substantial property damage.

3. Replace door securely after inspections (see WARNING, page 6).

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.

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

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 page 9. Call your qualified service technician to inspect the boiler and system.

End of season

Shut boiler down (unless boiler used for domestic water)

1.Follow “TO TURN OFF GAS TO APPLIANCE” on the page 9 of this manual.

2.Do not drain 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.
