New Heater-What duct and where do I get it?

[rogerdodger]

I am installing a new heater in the same place as the original. However, a PO tossed all the ducting. I need to run a 4" duct to the bedroom. Can I use the stuff from HD or Lowes, and the small registers? I cant seem to find any online anywhere.
Thank you,

You can use the metal dryer duct that HD or Lowe's has with fair success. It is not much different from what was in your Argosy to begin with. But, if you can find a way to use the straight solid metal ducts and fittings (el's etc) you will have better air flow, especially on longer runs.

Most RV parts places have some round plastic air outlets for a few dollars which may be easier to install in some locations than the home stile rectangular ones. They also may have duct material.

I did locate small round heater registers in brown and white locally.
Thanks again,

A tip on replacing the heater, if your airflow is too low, the output exhaust gets
really hot, my test is, can I hold my hand in front of it for 5 seconds.
I replaced the furnace in mine and needed to ad a duct in the bedroom to get the temp down. The old RT35 had a jet engine for a fan, new RT30 does not.
