GOLD GV Water boiler series 3 — manual

VIIc Start-up — read Section IX

Boiler sequence of operation

Lighting instructions

Manual Section IX contains information about the operation of the boiler and controls. Read this information, including the Sequence of operation diagram, to familiarize yourself with the normal operation of the control system. Note also the lockout conditions of the boiler control module, found on the control cover label.

Section IX also includes a Lighting instruction procedure for each gas valve used on the GV boiler (Figure 25 or 26).

Select the correct lighting instruction by reading the model number on the gas valve (can be viewed with the boiler front jacket panel removed). Use only the Lighting instruction procedure for this model gas valve.

Component operating information

Manual Section XI, Troubleshooting includes additional information about the operation of specific boiler components.

VIId Start-up — to operate boiler

Perform final checks before starting boiler

Read manual Section IX. Select the correct Lighting instruction procedure (Figure 25 or 26) based on the gas valve installed in the boiler.

Verify the boiler and system are full of water.

Start the boiler

Follow the correct Lighting instruction from Section IX to start the boiler.

See Section VIIe if boiler fails to start.

Verify the start-up preparation procedures of Section VIIb have been completed.

Do not use petroleum-based cleaning or sealing compounds

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

Verify that the gas/air orifice plate has been checked (and replaced if necessary) per manual Section IIc. Complete this procedure before starting boiler. Using an incorrect gas/air orifice plate will result in severe personal injury, death or substantial property damage.

Check system and boiler

Eliminate all system leaks.

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

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

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