Insulate humidifier drain tube from furnace flue
I installed a humidifier recently on my furnace. All mechanicals are
in a small closet, and the only way that the overflow tubing (3/8 ID vinyl tubing) can be routed to the drain is over the furnace flue - so gravity pulls the tubing into contact with the flue. Since this gets really hot (hot enough to melt the pipe wrap insulation I tried), I need a method to keep the tubing from melting. Any ideas? I'd like to avoid having to purchase and use mineral wool since I only need a tiny bit and that stuff is pretty nasty. Extra points for original ideas! Thanks everyone. |

Insulate humidifier drain tube from furnace flue
I have a hanger right now, but I consider this a temporary solution as
it looks very amateurish. Just wasn't sure if there was another option for a more professional look. I like the copper tubing idea, thanks! |

Cut the plastic tubing and use some soft copper in the high heat areas and hose clamp the plastic to the copper well away from the hot flue. |

Insulate humidifier drain tube from furnace flue
When I was more actively doing HVAC, we had metal parts
called "stand offs". The other suggestion to use copper tubing sounds right. -- Christopher A. Young Learn more about Jesus www.lds.org .. wrote in message ...
