Oil pressure pounds per square inch (psi) Table 8-5: Minimum Oil Burner Combustion StandardsĬarbon monoxide (CO) parts per million (ppm as measured) Smoke number should be near zero on all modern oil-fired equipment. Ü Adjust oxygen, flue-gas temperature, CO, and smoke number to match manufacturer’s specifications or specifications given here. Ü Adjust the air shutter to achieve the oxygen and smoke values, specified in Table 8-5 on page 261. Ü Adjust the barometric damper for a negative overfire draft of –0.020 IWC or –5 pascals at a test plug in the heating unit. If the nozzle is oversized, replace the burner nozzle after selecting the correct nozzle size, spray angle, and spray pattern. Exceptions: steam boilers and boilers with tankless coils. Ü A flue gas temperature more than 450° F is a sign that a clean heating unit is oversized. Ü Measure the overfire draft over the fire inside the firebox through a plug in the heating unit. Analyze the flue gas for O 2, flue-gas temperature, CO, and steady-state efficiency (SSE). Ü Sample undiluted flue gases between the barometric draft control and the appliance. Ü If the smoke number is higher than 3, take steps to reduce smoke before sampling the gases with a combustion analyzer to prevent the smoke from fouling the analyzer. Compare the smoke smudge left by the gases on the filter paper with the manufacturer’s smoke-spot scale to find the smoke number. Ü Sample the undiluted flue gases with a smoke tester, after reading the smoke tester instructions. Unless the oil-fired heating unit is very dirty or disabled, technicians should do combustion testing and adjust the burner for safe and efficient operation.Ĭombustion testing is essential to understanding the current oil burner performance and potential for improvement. The result is improved energy efficiency and a quieter home comfort system.SWS Detail: 5.3003.2 Combustion Analysis of Oil-Fired Appliances It automatically adjusts according to barometric pressure changes in your area. This barometric intake uses the natural power of air pressure to provide optimized ventilation. SKUTTLE's unique and patented barometric activated Fresh Air Intake measurement system provides exceptional performance by using ambient air pressure to determine the amount of fresh air needed to maintain a healthy and clean environment in your home or office. IT IS USED FOR ADJUSTMENT OF BAROMETRIC CAVITY PRESSURE IN ANY VENTED RECIRCULATION SYSTEM, INCLUDING CARPET FURNACES OR AS AN EXHAUST FAN SENSOR. IT AFFECTS THE VOLUME OF AIR FLOW TO THE RECIRCULATION SYSTEM. The higher the barometric pressure, the more open the damper will be to allow more fresh air into the system and vice versa. wc (24 "wg), the controller monitors the indoor barometric pressure. With the built-in barometric controller, SKUTTLE™ Fan Model 000-0216 and SKUTTLEPlus™ Fan Models 000-0492 and 000-0497 automatically adjust to changes in barometric pressure to deliver continuous, airflow-assisted make-up air. The SKUTTLE barometric controller can be used to provide makeup air to any heat exchanger. Measuring 4 inch diameter, the stainless steel device allows the incoming airflow to be regulated while maintaining a constant supply of fresh air to your home or office. Keep air levels consistent with this barometric make-up air control. Its self adjusting barometric draft control allows the operator to efficiently burn in excess of 85% of the available fuel while, at the same time, shutting down nearly all the full forced draft (F.F.D.) air supply. The Skutt Kettle is a very unique piece of equipment. All you have to do is mount the unit above an openable window with simple mounting hardware (provided) and it will The 4" diameter by 16'tall Skuttle Make-Up Air Control uses a potentiometer damper to power an electronic relay that automatically opens and closes in response to changes in outdoor air temperature. This unit has a self-adjusting barometric damper that automatically opens and closes according to weather conditions, allowing you to keep your indoor air quality and energy costs low. The Skuttle 002 Make-Up Air Control opens up the floor in your home to fresh, outdoor air.
