My intake vent is hot on my direct vent fireplace?
I have a direct vent stove installed. I'm curious how hot should the intake air pipe be? The run is about 18" and it has a rise of 1/8" to 1/4". There is a 6" fixed piece, a 7-12" adjustable piece which is at about 9" and the termination. When checking down the adjustable length I minimized any gaps because of ovality and seems... Wish it was perfect but assume this must be common. Should outside pipe get hot and if so... How hot? Given the over lap, rise, fit, and short run... I'm wondering if the pipe should be warm or hot... Or super hot
