PIPING AND CONTROLS

3. PIPING AND CONTROLS

Do not pipe boiler before jacket is NOTICE installed.

A.PRESSURE TEST BLOCK ASSEMBLY

1.Make up cold water supply connection to the boiler.

2.Install pressure gauge or pressure-temperature gauge in tapping provided. See Boiler Dimensional drawing, Figure 7.1 (Section 7).

3.Plug all open tappings in the boiler and fill with water. Apply approximately thirty (30) psig pressure. Check to make certain that all joints and fittings are water tight.

4.After all joints and connections have been proven tight, remove cold water supply and plugs from all tappings that are to be used. See Figure 7.1 (Section 7) for tapping locations.

B.BOILER RETURN CLEARANCE

Return piping must allow for opening and closing Burner Mounting Plate. PB Heat, LLC suggests installing a 1-1/4 NPT tee, a 90° elbow, and a 1-1/4 NPT x 5" long nipple in the return tapping before a vertical stand pipe is used.

C.STEAM BOILER PIPING

1.Refer to the Steam Installation Survey and Hydronics Institute Residential Hydronic Heating Installation/Design Guide for guidance.

2.See Figures 3.1 and 3.2. The return from system should always enter equalizer through Hartford Loop, 2" to 4" below normal water line (see dimensional drawing for normal water line).

3.See Table 3.1 for pipe size information.

4.Use swing joints to attach header to avoid damage to the boiler due to thermal expansion and contraction of steam header pipe.

5.Pipe the steam header a minimum of 24" above the normal water line using swing joints to attach the risers into the steam header.

ECT Series, EC Series specifications

The PB Heat EC Series and ECT Series represent a significant advancement in residential and commercial heating technology, providing reliable and efficient solutions for a variety of heating applications. These series are designed to meet the needs of homeowners and businesses seeking dependable heating while also prioritizing energy efficiency and comfort.

One of the standout features of the EC Series and ECT Series is their advanced engineering, which includes a range of high-efficiency boilers. These units utilize a cast iron heat exchanger that ensures excellent thermal transfer and durability. The cast iron construction is known for its longevity, enabling these boilers to withstand high temperatures and pressures, which is essential for long-term performance and reliability.

In terms of efficiency, both series feature energy-saving technologies that comply with the latest environmental standards. The EC Series, for example, boasts an impressive Annual Fuel Utilization Efficiency (AFUE) rating, indicating that a significant portion of the fuel consumed is converted into usable heat. This results in lower fuel bills and a reduced carbon footprint. The ECT Series further enhances efficiency with features like modulating burners that adjust the heat output based on demand, providing optimal comfort while minimizing energy waste.

Another notable characteristic of these series is their user-friendly controls and digital interfaces. The boilers come equipped with intuitive controls that allow homeowners to easily set and monitor their heating preferences. Many units also support advanced features, including Wi-Fi connectivity, enabling users to manage their heating systems remotely via smartphone applications.

In addition to their efficiency and user-friendly design, the PB Heat EC and ECT Series prioritize safety. These boilers incorporate multiple safety features, such as pressure relief valves and low water cut-off mechanisms, which help prevent operational hazards and ensure safe operation.

Overall, the PB Heat EC Series and ECT Series offer a robust combination of advanced heating technologies, efficiency, and safety. With their durable construction, energy-saving capabilities, and user-friendly controls, these heating solutions are ideal for those looking to invest in reliable and efficient heating systems. Whether for a residential property or a commercial facility, the EC and ECT Series stand out as exceptional choices in the modern heating landscape.
