GOLD CGi-4E Gas-Fired Water Boiler — Boiler Manual

7b Start-up — operate boiler

DO NOT proceed with boiler operation unless boiler and system have been filled with water and all instructions and procedures of previous manual sections have been completed. Failure to do so could result in severe personal injury, death or substantial property damage. Before start- ing the boiler, do the follow- ing:

Read manual Section 9 and the Operating instruction procedure applicable for the gas valve supplied on the boiler (Section 9c).

Verify the boiler and system are full of water.

Verify the Start-up prepa- ration procedures of Sec- tion 7 have been complet- ed.

Start the boiler

Follow the Operating instructions from Section 9c to start the boiler.

If you discover evidence of any gas leak, shut down the boiler at once. Find the leak source with bubble test and repair im- mediately. Do not start boiler again until corrected. Failure to comply could result in se- vere personal injury, death or

substantial property damage.

Eliminate all system leaks.

Continual fresh makeup water will reduce boiler life. Minerals can build up in sections, reduc- ing heat transfer, overheating cast iron, and causing section failure.

Glycol or antifreeze leaks

around the boiler may result in fire, causing severe personal injury, death or substantial property damage.

Do not use petroleum - based cleaning or sealing

compounds in boiler system. Severe damage to boiler will occur, resulting in substantial property damage.

See Section 7c if boiler fails to start.

Check system and boiler

1.Check system piping for leaks. If found, shut down boiler and repair immediately.

2.Vent air from system using manual vents. Air in the system will interfere with circulation and cause heat distribution problems and noise.

3.Inspect vent system thoroughly for signs of deterioration from corrosion, physical damage or sagging. In addition — Check for gas-tight seal at every connection and seam.

Venting system must be sealed gas-tight to prevent flue gas spillage and carbon monoxide emissions which will result in severe personal injury or death.

4.Check around the boiler for gas odor following the procedure of Section 7a of this manual.

5.Verify operation per Section 7b. Perform check-outprocedure in Section 8, and fill in the Installation and service certificate on the same page.
