1 Location of Wall Terminals The location of the wall terminations is one of the most important aspects of a direct-vent installation. Both the intake and exhaust terminations must be located on the same outside wall in order to balance wind pressure effects against the flow of exhaust gases. In addition, the wall terminations shall not be installed on that side of the building exposed to the prevailing wind direction or in alcoves and exterior building recesses where swirling wind conditions may occur.
Figure 2 Figure 2: Permissible exhaust termination locations. The venting system is only for a single appliance. Venting of an additional appliance could cause serious injury or loss of life. The venting system shall not be routed into, through, or within any other vent, such as an existing masonry or factory-built chimney. Screens on intake and exhaust terminals must be kept in good working order to prevent debris from entering the venting system.
2 Installation Procedures for Venting System General Guidelines: 1. The oil-fired boiler installation must be performed by a qualified installer in accordance with the regulations put forth in NFPA-31 Installation of Oil-Burning Equipment. The installation must comply with all local codes and authorities having jurisdiction. The installer must have the proper licensing and be experienced with all local codes and regulations. 2.
Installation Procedures: Exhaust Terminations and Exhaust Vent Piping. NOTE: Use only the approved materials listed on the previous page for direct venting of oil-fired Buderus G115 boilers. Use of any other materials, or systems not installed in accordance with the instructions contained in this manual will void the ITS listing. NOTE: Use strictly high temperature rated silicone (500 ºF rated silicone, G.E.
Installation of Insulated Flexible Oil Vent. 1. Apply a ¼" wide bead of high temperature silicone all around the boiler vent connection 1" from the end. Install 5" to 4" reducer on boiler vent connection. Secure properly with a clamp. 2. Carefully measure the required length of vent pipe and cut with a hacksaw. Allow for the two end adapters in your measurement. 3. Apply a small bead of silicone to the outside of the oil vent ends. Twist end adaptors to each end of the oil vent.
IMPORTANT NOTICES: ADVISE OWNER to keep intake and exhaust terminations free of debris and snow. Warning: Buderus Hydronic Systems, Inc. will not assume any responsibility for the possible effects of an obstructed air intake or exhaust termination. NOTE: MAKE SURE THE BURNER OBSERVATION PORT LOCATED ON THE BURNER DOOR IS SEALED AIR-TIGHT BY PROPERLY TIGHTENING THE PORT SCREW. USE EXTRA SILICONE SEALANT IF NECESSARY. TIGHTEN BURNER DOOR BOLTS EVENLY AND ENSURE AN AIR-TIGHT SEAL.
3 Operational Procedure Boiler Piping. Install the boiler piping according to the Installation manual furnished with the boiler. The pressure relief and tridicator should be installed on the provided tappings on the furnished supply manifold. The pressure relief should be piped to a suitable discharge. Boiler piping and related connections should conform to accepted industry standards using approved joint sealants and conform with local and State codes.
Burner Settings Always use instruments to check combustion. DO NOT ADJUST BURNER OPERATION BY EYE! CO2 analyser Draft gauge Fuel pressure gauge Stack thermometer Smoke tester Overfire measurements should be made from the burner observation port located at the front of the boiler. Make sure when taking measurements that the air space surrounding the pressure probe is completely blocked off with fiberglass or mineral wool.
4 Annual Maintenance The boiler and vent system should be inspected and serviced once annually by a qualified service person to maintain efficient operation of the system. Proper operation of boiler controls and safety devices must be verified during the annual service. Maintenance and service procedures 1. Disconnect the electrical power to the system and the fuel supply and air intake duct to the burner. Remove front panel jacket from the boiler. Remove burner door bolts and swing open burner door. 2.
5 Homeowner Information Warnings: 1. Never tamper with boiler or burner controls and settings. 2. Never place combustible materials within 5 ft of the boiler. 3. Only use fuel oil #2 or kerosene for your oil boiler. Never use gasoline, waste oil or other combustible materials in your boiler. 4. Never ignite any material in your boiler. The unit is designed for hands-off operation. 5. Do not plant vegetation directly under vent termination.
