Customer Questions & Answers

How is this wired to the gas valve on a water heater?

Asked by: Terry
In general that is not a good idea and i is not in your best interest. In almost all cases it is cheaper and easier to replace the water heater with one that is equipped with a factory installed power vent. Years ago people would do this because power vented water heaters were not available now they are. Second I would question why you are choosing a stainless steel power vent It is typically only used with oil and we would be excessive for a gas unit. However in answer to your question you would need a specialized control to do this. Field offers a number of different controls to be used to actuate the power vent based on the control strategy of the appliance. For example many water heaters have a mili-volt control system. The heat given off by the pilot causes the thermal couple to generate as small current of electricity. Field offers a specific control that will work with this low voltage and control the power vent. In most cases the cost of this control and the power vent would be more than the cost of a new water heater. Thus the market has changed and this is only done in very specific applications. The different controls are show on the Field Controls web site. If you have further questions you can give me a call. Chris 978 651-3301

Will this work with control kit on a Weil Mclain propane furnace made for chimney exhaust ?

Asked by: Alex
I assume that when you say Weil Mclain you are actually asking about a boiler and not a furnace. I would want to know which of there boilers you have. However I can say that this power venter is typically used on oil appliances. Oil exhaust is corrosive so stainless steel is often selected. You should be able to have a propane boiler power vented with a different and less expensive unit.

Can I replace the motor in this unit? If so, what kind?

Can I replace the motor in this unit? If so, what kind?
Asked by: Lynn
Replacement motors are available from Field. However oil exhaust is extremely corrosive and often by the time the motor fails much of the rest of the housing is so worn that it is a better practice to change the entire unit. I have found that due to the aggressiveness of oil exhaust that life expectancy of a oil power ventor is about seven if installed correctly on a properly sized and adjusted oil appliance. As the life of an oil appliance is roughly 20 years changing the power ventor two to three times in the appliances life is not uncommon. More often than that would suggest the appliance may be condensing or is not being maintained.

What are we looking at ?

I've reviewed the add and still don't know what I am looking at !
Asked by: ProfessorAC
This is a Field brand model SWG-4HDS. It is one of there most popular power vent units but made with some of the critical parts in stainless steel. A power vent is a unit that mechanically creates draft. Contrary to popular belief a chimney is not an exhaust pipe. A chimney is an air column that creates draft. Meaning exhaust is introduced into a chimney. Because it is warm it rises. This movement upward inside the air column creates a negative pressure or draft behind it. This suction draws more combustion air into the combustion chamber so that the combustion process can continue. For centuries we have used this natural draft principal on our furnaces, boilers, wood stoves, etc. Because of the cost of chimneys many new homes do not have them. Thus the draft needs to be artificially created. This unit does that. It pulls the exhaust through the heat exchanger and blows it through the side wall of the structure. If you just ran the exhaust vent out the wall, you would not have enough of a air column to create draft and dangerous exhaust would back up into the appliance. Because the largest component of exhaust is acidic water, this unit happens to be made with stainless steel components to prevent rot. Typically a oil boiler or furnace will last 20 years. However due to the acidic nature of the exhaust power ventors usually fail after about 7. As a result people will need an average of three during the life of the appliance. So we have made this common replacement part available. Please note that power vent units must be sized to the appliance they are being mated to. So it is important to make sure they are sized to be compatible. If you have further questions please feel free to give me a call. Chris 978 651 3301
