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

b.In Canada – When using manual main shutoff valves, it must be identified by the installer.

2.Install sediment trap / drip leg.

￿WARNING

The gas valve and blower will not support the weight of the piping. Do not attempt to support the weight of the piping with the boiler or its accessories. Failure to comply could result in severe personal injury, death, or substantial property damage.

4.Purge all air from the gas supply piping.

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

a.The appliance must be disconnected from the gas supply piping system during any pressure testing of that system at a test pressure in excess of 1/2 PSIG (3.5 kPa).

b.The appliance must be isolated from the gas supply piping system by closing a manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG (3.5 kPa).

c.The appliance and its gas connection must be leak tested before placing it in operation.

￿WARNING Do not check for gas leaks with an open flame – use the bubble test. Failure to

use the bubble test or check for gas leaks can cause severe personal injury, death, or substantial property damage.

6.Use pipe sealing compound compatible with propane gases. Apply sparingly only to male threads of the pipe joints so that pipe dope does not block gas flow.

￿ WARNING Failure to apply pipe sealing compound as detailed in this manual can result in severe

personal injury, death, or substantial property damage.
