User maintenance procedures

❏Service periodically . . . . . . . . . . . .

Clean vent termination & air intake screens

1.Remove all lint and debris from both the boiler air intake screen and the flue discharge screen.

2.The boiler control module will sense blockage of the air intake or flue and lockout if the blockage is excessive. It will signal the failure by flashing the appropriate indicator lights on the control board.

3.If removing the debris does not allow the boiler to operate correctly afterwards, contact your qualifed

service technician to inspect the boiler and vent/ air systems.

Test low water cutoff (if installed)

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.

❏Service every 6 months . . . . . . . . .

Operate boiler relief valve

1.Before proceeding, verify that the relief valve out- let has been piped to a safe place of discharge, avoid- ing any possibility of scalding from hot water.

To avoid water damage or scalding due to valve operation, a metal dis- charge 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 techni- cian in accordance with the instruc- tions in the Boiler manual. The discharge line must be terminated so as to eliminate possibility of se- vere burns should the valve dis- charge.

2.Read the boiler pressure/temperature gauge to make sure the system is pressurized.

3.Lift the relief valve top lever slightly, allowing wa- ter to relieve through the valve and discharge pip- ing.

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, con- tact 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 shutdown the boiler, fol- lowing the instructions on the inside jacket top Lighting Instructions. Call your qualified service technician to inspect the boiler and system.

Oil inducer motor

1.Use only S.A.E. 20 motor oil. DO NOT use house- hold universal oils.

Use only S.A.E. 20 motor oil to lu- bricate the inducer motor. Do not use common universal household oils.

2.Place a few drops of oil in each of the two oiler cups on the inducer motor.

The GOLD CG is a high-efficiency gas boiler designed for both residential and commercial applications. With its robust construction and intelligent engineering, it provides reliable heating while minimizing fuel consumption.

One of the standout features of the GOLD CG series is its advanced cast iron heat exchanger. This allows for excellent heat retention and optimal efficiency, ensuring that the boiler operates at a high performance level while consuming less energy. The cast iron design not only promotes longevity but also helps in maintaining consistent heating throughout the space.

Another key characteristic of the GOLD CG series is its modulating gas burner. This technology enables the boiler to adjust its output in response to the current heating demands, resulting in improved efficiency and significant energy savings. This modulation reduces short cycling, which can lead to increased wear and tear on the system over time.

The GOLD CG boilers are equipped with a user-friendly control interface, allowing homeowners and property managers to easily monitor and adjust settings. The integrated control system features advanced diagnostics that simplify troubleshooting and maintenance, making it easy to keep the system running smoothly.

Moreover, the GOLD CG series supports a wide range of installation options, including natural gas or propane configurations. This adaptability ensures that it can meet various heating needs, whether in smaller residential settings or larger commercial environments. Additionally, the compact design allows for easy placement in tight spaces, making it a versatile choice for numerous applications.

Environmental considerations are also at the forefront of the GOLD CG series. The boilers are designed to operate efficiently, which helps reduce greenhouse gas emissions. With high Annual Fuel Utilization Efficiency (AFUE) ratings, these boilers meet or exceed most energy efficiency standards, contributing to a more sustainable heating solution.

In summary, the Weil-McLain GOLD CG series stands out for its combination of efficiency, advanced technology, and thoughtful design. With features like a durable cast iron heat exchanger, modulating gas burner technology, and user-friendly controls, it provides reliable heating for a variety of applications while promoting energy conservation and sustainability. Whether for residential or commercial use, the GOLD CG series represents a top-tier choice for modern heating needs.
