GOLD CGs Gas-Fired Water Boiler

4Venting and combustion air

Install vent piping and air piping (if used) per appropriate Venting Supplement included in boiler envelope assembly.

Refer to Venting Supplements and to manual section 1 regarding requirements for:

•vent system

•combustion air openings

•combustion air quality

CGs Boiler must be vented and supplied with

combustion and ventilation air as described in Weil-McLain CGs Venting Supplements packed in envelope assembly with boiler. Failure to do so will cause severe personal injury or death.

Use direct vent (sealed combustion) if combustion air quality cannot be assured to be free of

contaminants. Refer to page 9 for a list of potential contaminants and locations likely to contain them. Operating the boiler with contaminated air will damage the boiler sections and vent, resulting in possible boiler failure or leakage of flue products, causing severe personal injury, death or substantial property damage.

5Gas piping

Connecting gas supply piping to boiler

1. Remove jacket front panel and refer to Figure 14 Figure 14 to pipe gas to boiler.

a.Install drip leg at inlet of gas connection to boiler. Where local utility requires drip leg to be extended to the floor, use appropriate length of pipe between cap and tee.

b.Install ground joint union for servicing, when required.

c.Install manual shutoff valve in gas supply piping outside boiler jacket when required by local codes or utility requirements.

d. In Canada — When using manual main shutoff valve, it must be identified by the installer.
