Traeger Boiler Installation
|End of Year|
|View this alone|
The TPB-150 hot water steel boilers are high quality pellet/corn/biomass fired heating units. The installation of the unit shall be in accordance with the regulations of the authories having jurisdiction in the state and county where you live.
All units should be inspected for damage upon arrival. Concealed damage claims should be filed immediatly against the carrier by the consignee. The carrier is responsible for taking prompt action on all claims.
A complete heat loss calculation of the structure is necessary to choose the proper size unit to install. The boiler should be sized to within 25% of the actual calculated heat loss of the structure. Over sizing will result in short cycling and inefficent operation. The PB150 bilers have large water content allowing for ample domestic hot water.
The Traeger boiler should not be sized for the firing rate of the existing boiler. A Department of Energy sponsored study indicates 65% of the heating units in U.S. homes are substantially oversized.
Boiler must be installed on a non-combustible heat resistant surface in a liquid containment pan. The containment pan should be attached to a drain and in a level position with clearances in accordance with NFPA 31, Table 4-1, Form IL
Front Clearance 24" Sides 6" Rear 6" Chimney Connector 18" Reduced clearance installations shall comply with NFPA 31, Table 4-2, Appendix B.
To move the unit, push against the flue box or skids. Pushing or pulling the jacket or burner will result in damage.
Be sure to level the unit by inserting shims under the base.
Air for Combustion and Ventilation
The unit must be installed where provision exists for combustion and ventilation air. Ordinarily, provisions may be furnished by the following methods:
In buildings of tight construction, including most modern homes, you should provide an opening, connecting to a well ventilated attic, crawl space or directly with the outdoors. This opening should have a minimum free area of 1 square inch per 1,000 BTU per hour of total input for all appliances in the enclosure and should terminate below the burner lever. Boilers installed in confined areas must have two ventilation opens in the door. Each opening should have a free area of not less than 1 square inch per 1,000 BTU of the total input for all appliances in the enclosure. One opening located near the top of the enclosure and one near the bottom.
Where a boiler is installed in a full basement, infiltration is normally adequate to provide air for combustion.
In buildings of tight construction, where basement windows are weather stripped, one opening communicating with a well ventilated attic or with the outdoors should be provided. The opening should have a minimum free area of 1 square inch per 1,00 BTU per hour of total input for all appliances in the basement.
Where a boiler is located in an area where the operation of exhaust fans, kitche ventilation systems, clothes dryers, or fireplaces may create conditions of unsatisfactory combustion or venting, special provisions should be made for additional air for combustion as specified by local authority.
Install the safety relief valve in the 3/4" tapping in the back of the boiler. The relief valve should be piped to a safe place of discharge. Install the altitude gauge in the 1/4" fitting provided in the coil plate.
Minimum supply and return pipe size of not less than 1-1/4" to be used! The recommended locations of pumps, expansion tanks, etc. are illustrated in the Figures 2,3 & 4. Relief valve discharge and drain valve piping should be piped to a safe place of discharge. All plugs and water connections should be checked for leaks upon installation and annually there-after.
Tank-less Water Heating Piping
The tank-less heater may be connected as shown in Figure 4. A mixing valve may be used to reduce the water temperature at kitchen or bathroom taps. When connecting to the domestic water coil a pressure temperature relief valve must be installed.
Install relief valve in top tapping on rear of boiler. Relief Valve discharge and drain valve piping should be piped to a safe area for discharge. In the event of a run-away boiler, the water coming out of the relief valve could be extremely hot, and it could come out at very high pressure. Locate the relief valve discharge away from where people usually stand.
The diagram shows the two potential locations for circulation pumps.
- Pump location option 1 is a legacy pumping design and the circulating pump pulling on the load, as here forcing cool water to be heated and pushed out of the boiler- will expand and create air bubbles that become trapped in your heating system. Examples of how and why may be found in books and documentation as "Pumping Away" or "The Golden Rules of Hydronic Heating" written by Dan Holahan.
- Pump location option 2 is the better spot. Locate your circulation pump on the supply outlet at the top of the boiler, and use it to pump heated liquid AWAY from the boiler, to your radiation load.
