Weil-McLain 550-110-260/02002 7a Start-up— preparation continued, 7b Start-up- operate boiler

GOLD CGs Gas-Fired Water Boiler

7a Start-up — preparation continued

Inspect system water piping Inspect base insulation

After filling the boiler and system with water, inspect all piping throughout the system for leaks. If found, repair immediately. Repeat this inspection after the boiler has been started and the system has heated up.

Leaks must be repaired at once.

Failure to do so can damage the boiler, resulting in 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.

Check to make sure insulation is secure against all four sides of the base. If insulation is damaged or displaced, do not operate boiler. Replace or reposition insulation.

Failure to replace damaged insulation or reposition insulation can result in a fire hazard, causing severe personal injury, death or substantial property damage.

The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions on page 60 of this manual. Failure to comply could result in severe personal injury.

7b Start-up — operate boiler

Final check before starting boiler

•Read manual section 9 including the Lighting instructions procedure (Figure 21, page 34).

•Verify the boiler and system are full of water.

•Verify the Start-up preparation procedures of section 7a have been completed.

Start the boiler

•Follow the Lighting instructions from section 9c to start the boiler.

•See section 7c if boiler fails to start.

Check system and boiler

Do not use petroleum-based cleaning or sealing compounds in boiler system. Severe damage to boiler will occur, resulting in substantial property damage.

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.

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-tightto prevent flue gas spillage and carbon monoxide emissions which will result in severe personal injury or death.
