BOILER SYSTEM PIPING

The drawings in this section show typical boiler piping installations. Before beginning the installation, consult local codes for specific plumbing requirements. Be sure to provide unions and valves at the boiler inlet and outlet so it can be isolated for service. You must install an air separation device in the installation piping to eliminate trapped air in the system. Locate a system air vent at the highest point in the system. The system must also have a properly sized expansion tank installed. Typically, an air charged diaphragm-type compression tank is used. You must install the expansion tank close to the boiler and on the suction side of the system pump to ensure proper operation.

￿CAUTION: This boiler system should not be operated at less than 12 PSIG.

Provide suitable hangers or floor stands to support hot water piping. The boiler alone should not support hot water piping. Copper pipe systems are subject to considerable expansion and contraction. Rigid pipe hangers could allow the pipe to slide in the hanger resulting in noise transmitted into the system. Use padding on rigid hangers installed with a copper system. Pipe the boiler pressure relief valve to a suitable floor drain. See the relief valve section in this manual.

￿CAUTION: A leak in a boiler "system" will cause the "system" to intake fresh water constantly, which will cause the tubes to accumulate a lime/scale build up. This will cause a non-warrantable failure.

General Plumbing Rules

1.Check all local codes.

2.For serviceability of boiler, always install unions.

3.Always pipe the pressure relief valve to an open drain.

4.Locate system air vents at the highest point of system.

5.Expansion tank must be installed near the boiler and on the suction side of the pump.

6.Support all water piping.

Water Connections: Heating Boilers Only

Inlet and outlet water connections on models 495,000 - 745,000 Btu/hr have 2" NPT and on models 985,000 - 2,065,000 Btu/hr the inlet and outlet connections are 2 1/2" NPT.

Note: Field-installed reducing bushings may decrease flow resulting in boiler noise or flashing to steam.
