Direct vent has to be set properly for it to pull the air and gasses from the stove and push them outside. The direct vent fan has to be pulling more than the combustion fan is pushing in so the firebox will be in a negative pressure. If they are not balanced out then the combustion fan will put more air in than the direct vent is pulling out. Then the gasses stop flowing and when that happens the fire will go out.
OK, so I do that by pulling out the rod on the vent motor? I'm guessing just a little at a time? The guy that got me going on this told me not to mess with the rod on the vent motor, but it sounds like I have to. The rod is just about all the way in now. He told me pulling the rod out pulls less draft. Is that correct? Is that what I need to do?
