Beckett burners are developed and listed with petroleum fuel oil (burner fuel) meeting the national fuel standard, ASTM D396. From time to time, it is desirable or necessary to use alternative fuels that essentially meet this standard. The following list indicates the fuels that can be used ...
Oil viscosity can be simply defined as the measure of the oil’s resistance to flow. No doubt most of us have seen what happens to syrup or molasses on a cold morning. In order to get the cold mass to flow easily, we had to add some heat. Actually, what we were experiencing was a change in ...
The goal of every oil burner serviceman is to assure dependable, on-going heat for the customer. This is why filtration of the oil supply makes sense. Look inside the fuel oil pump, or a burner nozzle and you’ll see that filters are included by the manufacturers of these components. They know ...
It’s that time of year: new installations, no-heat calls, annual tune-ups. Each situation calls for proper burner adjustment.
Whether you are installing a new burner, solving a problem, or conducting an annual service call, you eventually get to the point where you have to adjust the burner. ...
Most servicemen have personal strategies that work effectively for them. Results count, so use what methods you find effective. To help you, we have developed the following simplified procedure based on what many servicemen use.

Using supply line filters with oil burning equipment makes good sense. A major reason is the age of the oil tanks in the field. Over the years, sediment, or sludge, accumulates in the tanks. The sludge is produced from the molecules of water and heavy oil that form in suspension. As they get ...
The cadmium sulfide cell, or cad cell, is part of the primary control system and is used to sense the presence of the oil burner flame. The cad cell assembly consists of the actual cell, a holder, and cord to connect the cell to the primary control. This detector is mounted in the air tube of ...
The ignition transformer takes 120 volts AC and transforms it into 10,000 volts AC to ignite the oil droplets.
There are a number of ways to test the output voltage of the transformer. The most accurate is to use a voltmeter capable of measuring 10,000 volts. With 120 volts input to the ...
Direct – or through-the-wall – venting of oil fired heating equipment is becoming a major discussion topic in the oil heat industry. This month we will look at direct venting and its benefits and drawbacks.Direct venting systems eliminate the need for a chimney. An induced draft fan typically ...
This bulletin will discuss the low firing rate baffle: what it is, what it does, and when it is needed. The Beckett low firing rate baffle is a small metal plate. It is about 3-3/4″ x 1-3/4″ in size, and has a length-wise bend in the middle. (Figure 1.)
The baffle is installed over the back ...
Heating appliance soot-up can be prevented if you know the causes. In this era of increased appliance efficiency, the service industry must stay abreast of new advances and the new requirements that must be met.
Appliances are more compact and streamlined. The emphasis is on AFUE ratings and ...
