But a hopper fire from over drafting is.
coalishot wrote:Also it appears to me that with the higher draft the opposite is occurring the flames are being pulled up and away from the hopper making a fire even more unlikely. I think I was more at risk for one before.
coalishot wrote:The draft doesnt pull through the hopper on my model. The hopper is sealed. The least path of resistance is through the grate which is being induced already by the 2.nd of my 3 motors (still not happy about running 3 motors).

.09 cents per kilowatt hour? Thats half of what i pay in my neck of the woods.coalishot wrote:Did math on inducer motor. it is rated at .43 amps at .09 cents per kilowatt hour (for now in Pa see this link

) running 24/7 for 31 days a month I come up with $3.45 a month to run it. The combustion fan on my liberty is much smaller but I dont see amp or watt rating but it must be about half the draw of this motor. The blower motor is in housing and i cant see that tag either but i would say it is probably twice the use of the inducer i will put amp probe on both and get actual readings and post some day soon. Also rated watts and amps are usually max and most motors run under rated amps/watts.
