Why do the motors on the SWG power venters seem to fail more frequently on an oil-fired system than on a gas-fired system?
One of the biggest causes of premature motor failure is the power venter being sized to the BTU rating of the appliance and not to the firing rate of the appliance. The second major cause of premature motor failure is insufficient combustion air. With tighter house construction you do not get proper air exchanges. The power venter will draw out the air it needs to make the appliance fire efficiently; it will be working against the room, causing improper burning of the oil. This will cause the flue gases to be more acidic which will result in the whole motor assembly deteriorating more rapidly. The third cause of premature motor failure is using a petroleum-based lubricant instead of the recommended SWG Super Lube, which is a super lightweight synthetic lubricant. The motors are factory lubricated using the SWG Super Lube and a petroleum-based lubricant will not mix with the synthetic lubricant. This will prevent any lubrication of the bearing, which will cause the bearings to break dow
