WARNING

Figure 1.1: Accessibility Clearances – Floor Standing Units

Figure 1.2: Accessibility Clearances – Wall Hung Units

A. GENERAL

1. Pinnacle boilers are to be installed in an area with a floor drain or in a suitable drain pan. Do not install any boiler where leaks or relief valve discharge will cause property damage.

2. This boiler is not intended to support external piping. All venting and other piping should be supported independently of the boiler.

3. Install this boiler level to prevent condensate from backing up inside the boiler.

B. WALL HUNG BOILERS

1. The PI-T50 and PI-T80 Boilers are provided with slots for wall mounting and feet for floor mounting. Refer to Figure 10.1 in this manual for dimensions & locations.

2. If wall mounted, the boiler must be attached to a wall that provides adequate support for the boiler.

3. Use a minimum of 1/4" threaded fasteners for supporting the boiler. Do not mount the boiler to wall board only.

4. Be sure to adequately support the boiler while installing external piping. Be sure to pipe condensate to a suitable drain or condensate pump.

C. FLOOR MOUNTED BOILERS

1. PI-80, PI-140, and PI-199 boilers are designed for floor mounting. The PI-80 can be wall mounted using the optional boiler stand available through your PB Heat, LLC distributor (Part Number 91439).

2. The boiler stand may used for floor mounting of the PI-140 and PI-199 boilers.

2. BOILER SET-UP

BOILER SET-UP

This boiler is must be installed level to prevent condensate from backing up inside the boiler.

CAUTION

Make sure the boiler is adequately supported. Do not install this boiler on drywall unless adequately supported by wall studs.

WARNING

A. GENERAL

1. The water supply and return piping of this appliance are to be sized according to system requirements. Do not use piping smaller than the boiler connections.

2. In hydronic systems where sediment may exist, install a strainer device in the boiler return piping to prevent large particles and pipe scale from entering the boiler heat exchanger coil. Use a large mesh screen in the strainer.

3. Install this boiler so that the gas ignition system components are protected from water (dripping, spraying, etc.) during appliance operation and service (circulator replacement, condensate trap cleaning, control replacement, etc.).

B. OPERATING PARAMETERS

1. The Pinnacle boiler is designed to operate in a closed loop hydronic system at approximately 15 psi. A pressure limit in the boiler header will prevent the unit from operating if the pressure drops below 10 psi. This is to keep the appliance from operating in the event of a system leak or other condition in which water is not flowing through the heat exchanger.

2. Table 3.1 shows minimum water flow rates for Pinnacle boilers. If a glycol solution is to be used, contact the factory for minimum flow rates.

C. SYSTEM COMPONENTS

1. Figure 3.1 shows the symbol key for piping diagrams in this section. The following are brief descriptions of system components.

2. Pressure/Temperature Gauge: A combination pressure/temperature gauge is provided with each Pinnacle boiler to be mounted in the piping from the boiler supply to the system. Most local codes require this gauge.

3. Air Elimination: Any closed loop hydronic system in which the Pinnacle boiler is installed must have an air elimination device. As the system water is heated, dissolved oxygen and carbon dioxide will separate from the liquid. An air elimination device (such as a TACO 430 Series Air Scoop with automatic air vent) is required to remove the dissolved gasses from the system preventing corrosion in the piping system and eliminating system noise.

4. Expansion Tank: An expansion tank (such as a Bell & Gossett Series HFT) is required to provide room for expansion of the heating medium (water or glycol solution). Consult the expansion tank manufacturer's instructions for specific information regarding installation. The expansion tank is to be sized for the required system volume and capacity. In addition, be sure that the expansion tank is sized based on the proper heating medium. Glycol solutions may expand more than water for a similar temperature rise.

5. Y-Type Strainer: In older systems where a significant amount of sediment may be present, it may be necessary to install a Y-type strainer. The strainer should be checked often and cleaned during the first few months of operation to assure that sediment does not reach the heat exchanger and clog the passages. Use a large mesh screen in the strainer.

6. Flow Control Valve: Flow control valves such as the TACO Flo-Chek or Bell & Gossett Flo-Control™ are used to prevent gravity circulation by incorporating a check valve with a weighted disc.

7. Pressure Reducing Valve: A pressure reducing valve, such as the Bell & Gossett B-38 or a TACO #329, is used in a hydronic system to automatically feed water to the system whenever pressure in the system drops below the pressure setting of the valve. These valves should not be used on glycol systems unless close supervision of the glycol solution is practiced.

8. Back Flow Preventer: A back flow preventer (check valve) is required by some jurisdictions to prevent the hydronic system water from backing up into the city water supply. This is especially important on systems in which glycol solution is used as the heating medium.

Use only inhibited propylene glycol solutions which are specifically formulated for hydronic systems. Unlike automotive antifreeze, solutions for hydronic applications contain corrosion inhibitors that will protect system components from premature failure due to corrosion.

CAUTION

Use only inhibited propylene glycol solutions which are specifically formulated for hydronic systems. Ethylene glycol is toxic and may cause an environmental hazard if a leak or spill occurs.

WARNING

9. Pressure Relief Valve: The boiler pressure relief valve is factory installed into the right side boiler manifold (inside the jacket). Pipe the discharge of the relief valve to within 12" of the floor and close to a floor drain. Provide piping that is the same size or larger than the relief valve outlet.

10. Circulator: The boiler circulator is to be sized to overcome the pressure drop of the system while providing the flow required by the boiler.

a. If the boiler is piped in a secondary loop of a

primary/secondary heating system, the circulator will need only to overcome the resistance of the boiler and any fittings in that loop.

b. The circulator should be sized based on the net

output of the boiler. The Table 3.2 shows the Boiler Output as reported to the Hydronics Institute division of GAMA. These values are based on a pickup factor of 1.15.

Pipe the discharge of the relief valve as close as possible to the floor and away from high traffic areas. Pipe the discharge to a floor drain. Failure to do so may result in personal injury and/or property damage.

CAUTION

c. The required flow rate can be calculated based

on the design temperature difference from the return to the supply of the boiler. For a PI-T80 with a design temperature difference of 20°F the calculation is as follows:

d. Table 3.3 shows the pressure drop (in feet of

water) for a flow rate which gives a 20°F temperature difference for each boiler model.

e. The boiler pressure drop for various flow rates

can be determined by using Figure 3.2, the Pinnacle Circulator Sizing Graph.

f. Table 3.4 gives the recommended circulators for

a boiler on a secondary loop with water as the heating medium.

g. Special consideration must be given if anti-freeze is

to be used as a heating medium. Propylene glycol has a higher viscosity than water therefore the system pressure drop will be higher.

10. Indirect Water Heater: An indirect water heater should be piped in a dedicated zone. It consists of a water tank that is heated by boiler water passing through an internal coil. Examples of indirect water heating are shown in the System Piping subsection of this Section.

WATER PIPING AND CONTROLS

The circulator sizing given is for primary/secondary installations only. The system circulators must be sized based on the flow and pressure drop requirements of the system.

D. SYSTEM PIPING

1. Figure 3.3 shows a single boiler with two zones. In this application, the Peerless Partner indirect water heater and the single heating zone require similar water temperature.

2. Figure 3.4 shows an additional zone in which baseboard radiation is the heat load. This zone also requires water temperatures similar to the indirect water heater.

3. Figure 3.5 shows diverter tees used in combination with conventional hydronic radiators on an additional zone. A second boiler is also added to the system. Notice that the boilers are piped in parallel on the secondary loop. It is important that the common headers are sized to match the system piping. Smaller headers may result in flow fluctuations through the boilers.

4. Figure 3.6 shows a system in which several different types of loads and multiple boilers are shown. This system illustrates how different temperature zones can be supplied from the same source by mixing down the temperature using a three way mixing valve. Radiant flooring typically requires much lower temperatures than baseboard radiation and indirect water heating. Notice that a third boiler is included in this system.

5. Figure 3.7 shows zone valves used in place of zone circulators. Notice that this system utilizes reverse return piping which makes it easier to balance the system. If the heating zones are very different in length, the balancing valves on the return side of each loop are required.

E. FREEZE PROTECTION

1. Glycol for hydronic applications is specially formulated for this purpose. It includes inhibitors which prevent the glycol from attacking metallic system components. Make certain that the system fluid is checked for the correct glycol concentration and inhibitor level.

2. Use only inhibited propylene glycol solutions of up to 50% by volume. Ethylene glycol is toxic and can chemically attack gaskets and seals used in hydronic systems.

3. The antifreeze solution should be tested at least once per year and as recommended by the antifreeze manufacturer.
