Boiler Manual

5 Gas piping continued

2.Support piping with hangers, not by boiler or its accessories.

3.Purge all air from gas supply piping.

4.Before placing boiler in operation, check boiler and its gas connection for leaks.

a.Close manual main shutoff valve during any pressure testing at less than 13" w.c.

b.Disconnect boiler and gas valve from gas supply piping during any pressure testing greater than 13" w.c.

Do not check for gas leaks with

an open flame — use bubble test. Failure to use bubble test or check for gas leaks can cause severe personal injury, death or substantial property damage.

5.Use pipe dope compatible with propane gases.

Apply sparingly only to male threads of pipe joints so that pipe dope does not block gas flow.

Failure to apply pipe dope as detailed above can result in severe personal injury, death or substantial property damage.

Natural Gas:

1.Refer to Table 4 for pipe length and diameter. Base on rated boiler input (divide by 1,000 to obtain cubic feet per hour). Table 4 is only for gas with specific gravity 0.60, with a pressure drop through the gas piping of 0.30" w.c. For additional gas pipe sizing information, refer to ANSI Z223.1 (or B149.1 or B149.2 for Canadian installations).

2.Inlet pressure required at gas valve inlet:

•Maximum: 13" w.c.

•Minimum: 5" w.c.

•Manifold gas pressure: 3.5" w.c.

3.Install 100% lockup gas pressure regulator in supply line if inlet pressure exceeds 13" w.c.

￿￿￿￿￿￿￿￿￿￿￿￿Adjust for 13" w.c. maximum.

1.Contact gas supplier to size pipes, tanks and 100% lockup gas pressure regulator.

2.Adjust propane supply regulator provided by gas supplier for 13" w.c. maximum pressure.

3.Inlet pressure required at gas valve inlet:

•Maximum: 13" w.c.

•Minimum: 11" w.c.

•Manifold gas pressure: 10" w.c.
