GOLD CGi Gas-Fired Water Boiler — Boiler Manual

10b Service & maintenance – annual start-up (cont.)

Safety relief valves should be reinspected AT LEAST ONCE EVERYTHREEYEARS, by a licensed plumb- ing contractor or authorized inspection agency, to ensure that the product has not been affected by corrosive water conditions and to ensure that the valve and discharge line have not been altered or tampered with illegally. Certain naturally occurring conditions may corrode the valve or its compo- nents over time, rendering the valve inoperative. Such conditions are not detectable unless the valve and its components are physically removed and inspected. This inspection must only be conducted by a plumbing contractor or authorized inspection agency — not by the owner. Failure to reinspect the boiler relief valve as directed could result in unsafe pressure buildup, which can result in severe personal injury, death or substantial property damage.

Following installation, the valve lever must be operated AT LEAST ONCE AYEAR to ensure that waterways are clear. Certain naturally occurring mineral deposits may adhere to the valve, rendering it inoperative. When manually operating the lever, water will discharge and precautions must be taken to avoid contact with hot water and to avoid water damage. Before operating lever, check to see that a discharge line is connected to this valve directing the flow of hot water from the valve to a proper place of disposal otherwise severe personal injury may result. If no water flows, valve is inoperative. Shut down boiler until a new relief valve has been installed.

❏Review with owner

1.Review the User’s Information Manual with the owner.

2.Emphasize the need to perform the maintenance schedule specified in the User’s Information Manual (and in this manual as well).

3.Remind the owner of the need to call in a licensed contractor should the boiler or system exhibit any unusual behavior.

4.Remind the owner to follow the proper shutdown procedure and to schedule an annual start-up at the beginning of the next heating season.

❏Cleaning boiler heating surfaces

The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions on page 68 of this manual. Failure to comply could result in severe personal injury.

1.Shut down boiler:

•Follow “To Turn Off Gas to Appliance” instructions on boiler and Operating instructions.

•Do not drain boiler unless it will be exposed to freezing temperatures. If using antifreeze in sys-

tem, do not drain.

Boiler relief valve

1.Inspect the relief valve and lift the lever to verify flow as in the following warnings, excerpted from a relief valve manufacturer’s warning label. Before operating any relief valve, ensure that it is piped with its discharge in a safe area to avoid severe scald potential. Read manual Section 4 before proceeding further.

2.After following the above warning directions, if the relief valve weeps or will not seat properly, replace the relief valve. Ensure that the reason for relief valve weeping is the valve and not over-pres- surization of the system due to expansion tank waterlogging or undersizing.

2.Follow shutdown procedure.

3.Remove venting system connection to boiler.

4.Remove top jacket panel. Turn back insulation.

5.Remove collector box/transition assembly. Clean sealant from assembly and sections.

6.Remove radiation plates hanging between sections.

7.Remove burners from base. Brush and vacuum burners to remove all dust and lint. Verify that all burner ports are free of debris.

8.Place newspapers in base of boiler to collect soot.

9.Clean between sections with wire flue brush.

10.Remove newspaper and soot. Vacuum or brush base and surrounding area.

11.Reinstall radiation plates.

12.Replace collector box/transition assembly. Seal with seal- ant. Obtain gas-tight seal to prevent flue gas spillage and carbon monoxide emissions, resulting in severe personal injury or death.

13.Replace insulation and jacket top panel.

14.Start up boiler following Section 7, pages 32-35 of this manual and the boiler Operating instructions. Excessive sooting indicates improper gas combustion. If found check for proper combustion and make any necessary adjustments.
