•Port openings must be of captured seal design – a machined groove assures uniform compression of the sealing ring and protects the seal from contaminants. Elastomer sealing rings are to be used to provide permanent water-tight seal between sections. Unlike cast iron or steel push nipples, the elasticity of the seals fills any gaps caused by misalignment or expansion or contraction.

•Provided with flexible refractory blankets attached to back and floor of combustion chamber.

•Shipped with insulated heavy gauge steel jacket(s) with durable powdered paint enamel finish. Jacket designed to be installed after connecting supply and return piping.

D.Tankless heaters or indirect water heaters

• Provide ( ) internal tankless water heater(s) inserted into the left hand side of the tankless intermediate (TI) section in the opening provided. Allow 34” minimum clearance on left side of boiler for cleaning and servicing. Tankless openings must be on same side as the flue passage cleanout plates to minimize space requirements.

E.Boiler foundation(s):

•Installer to construct needed support and level concrete foundation(s) where boiler room floor is uneven or will not support the weight of the boiler(s).

F.Boiler trim:

1.All electrical components to be of high quality and bear the U.L. label.

a)Water boiler(s) controls furnished:

1)Combination low temperature limit (operating) and high temperature limit control.

2)Low temperature limit set according to system design. High temperature limit set at least 20°F higher than the low limit (240°F is the maximum allowable water temperature).

3)Combination pressure-temperature gauge with dial clearly marked and easy to read.

4)ASME certified pressure relief valve, set to relieve at 30 PSIG. Optional relief valves available up to and including maximum allowable pressure. Side outlet discharge type; contractor to pipe outlet to floor drain or near floor, avoiding any area where freezing could occur.

b)Steam boiler(s) standard controls furnished:

1)Low pressuretrol (operating) and high pressuretrol set at maximum pressure as a safety control.

2)Steam pressure gauge with dial clearly marked and easy to read.

3)Gauge cock water set with gauge glass, guards and aluminum water level plate.

4)ASME certified pressure relief valve, set to relieve at 15 PSIG. Side outlet discharge type; contractor to pipe outlet to floor drain or near floor, avoiding any area where freezing could occur.

c)Low water cut-off for water or steam boiler(s):

1)Boiler(s) to be furnished with U.L. labeled low water cut-off with ASME working pressure rating equal to the ASME rating of the relief valve.

2)Do not use quick-connect fittings on boiler(s).

3)Install cut-off according to manufacturer’s instructions.
