I live in New England.It can be 0 degrees

at night.

I have to put in a gas fired hot air furnace

and because of the furnace(90%)location there may be as much as 17' of 3" pipe

exposed to the elements.Assuming the correct

pitch and insulation wrap am I in any danger

of a freeze-up?

I am getting conflicting input.

Thanks in advance...........

Mositure will condense in that pipe, its a condensing furnace. If you dont have a PVC condensate drain line heater maybe you should call the factory or your local dealer and ask them to install it. If the water freezes in the pipe it will change the inside dimensions of the pipe and if enough of the area in the pipe is changed it can affect the pressure switch, and cause the unit to shut down because the unit can not establish the proper exhaust pressure.

Simpl read the installation booklet and the product should mention the condensate drain line heater.
