Installation Clearances WARNING Boilers in rooms shall be installed with the clearances from combustible materials not less than indicated below. Combustible materials are those made of or surfaced with wood, compressed paper, plant fibers, plastics, or other material that will ignite and burn, whether flame proofed or not, or whether plastered or not. The boiler must not be installed on combustible flooring. The boiler is approved for installation on non combustible flooring only.
hundred (100) square inches. These openings must freely communicate with the interior areas having adequate infiltration from the outside. When the boiler is installed in a confined space and all air is provided from the outdoors, the confined space shall be provided with two permanent openings. One commencing within 12 inches from the top, and one commencing 12 inches from the bottom of the enclosure.
IMPORTANT In accordance with Section 325 (f) (3) of the Energy Policy and Conservation Act, this boiler may be equipped with a feature that saves energy by reducing the boiler water temperature as the heating load decreases. This feature may be equipped with an override which is provided primarily to permit the use of an external energy management system that serves the same function.
Pipes that are connected to boiler fittings must be supported and placed so that they do not create stresses on the boiler fittings themselves. BY PASS PIPING IS REQUIRED ON ALL LOW MASS BOILERS WHERE THE BOILER RETURN WATER TEMPERATURE COULD OPERATE BELOW 130ºF FOR EXTENDED PERIODS OF TIME. The Solaia boiler is a highly efficient low mass boiler in which care must be taken to ensure that high volumes of low temperature water are not introduced into the boiler.
Prior to installation of the boiler, the chimney or venting system shall be examined by the installer and determined to be in good condition. All joints of the chimney must be tightly sealed. The inside of the chimney should be free of all obstruction, such as loose brick, broken pieces of tile, or corroded metal. If chimney flues are divided or there are multiple flues within one chimney, make sure there are no openings in the partition separating the divided or individual flues.
the vent pipe connector shall not exceed 10 feet. The chimney connector shall be installed so as to minimize the number of elbows and to avoid sharp turns or other construction features that would create excessive resistance to the flow of flue gasses. Tees may be used in a straight section in conjunction with a barometric draft regulator; however, they must not be used for a 90° turn. No device that will obstruct the free flow of flue gasses shall be installed in the chimney connector.
Direct Venting Oil Fired Boilers WARNING Failure to follow all instructions can result in flue gas spillage and carbon monoxide emissions, causing severe personal injury or death. Direct vent systems are intended for oil fired boilers only and are not designed for gas fired boilers. All installations must meet the requirements of NFPA31. Use only the ETL listed venting system components supplied with the packaged boiler.
3. COMBINATION AIR INTAKE/VENT SYSTEM The vent system consists of 10 or 15 foot lengths of double wall insulated flexible stainless vent piping and an equal length of 4” air intake piping and a stainless steel intake/vent termination end. Consult the Direct Vent manual included with the direct vent kit for more detailed installation instructions. Install the vent termination thru the opening in the wall centering it in opening.
DIRECT VENT OIL BURNERS Riello Burners All Riello direct vent burners are shipped with the nozzle for the SLD375 installed. A separate nozzle is included in the burner carton for the SLD4100 and SLD5125. See the burner set up page or the Installer Serviceman Label attached to the boiler for the appropriate burner settings. Boilers supplied with Riello burners will also be supplied with a 3” to 4” galvanized adapter.
On a two- pipe system you will need to supply a second approved flexible oil line in order to be able to swing the burner door open without disconnecting oil lines. An optional flexible oil line is available through your distributor. Gas Piping Connect from the gas supply to the burner combination gas valve inlet using new, approved gas lines and fittings only. Provide support for gas piping. Do not rest weight of piping on burner gas valve. Apply pipe dope sparingly at all joints.
