gas-fired water boiler — User’s Information Manual

Maintenance procedures — EVERY 6 MONTHS

Check the boiler piping

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 qualified service technician. Failure to comply could result in severe personal injury, death or substantial property damage.

Operate relief valve

1. Reinstall door securely after inspections.

Reinstall the jacket front door after servicing. The boiler front door must be securely fastened to the boiler to prevent boiler from drawing air from inside the boiler room. This is par- ticularly important if the boiler is located in the same room as other appliances. Failure to keep the door securely fastened could result in severe personal injury or death. Contact your installer or technician immediately if the front door does not correctly in place or if the door gaskets are damaged.

2.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 qualified heating installer or service technician in accordance with the in- structions 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.

3.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.

4.If water flows freely, release the lever and allow the valve to seat. Watch the end of the relief valve dis- charge 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.

5.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.
