Need burner tube for Heatilator DVi40

[Steve Up North]

This is my first gas fireplace insert so I had a tech come and service it. The prior homeowner installed it but it's rotted out. The part number should be 20433 but the tech says they're obsolete.
I tried the internet under Heatilator, Heat N Glo, Hearth & Home Technologies, but cannot find one.
Anybody know of a source? I really can't afford to tear it out and install a new one for a stupid burner tube.

I'd contact a local welder & bring the burner tube to him. He may be able to duplicate - or repair - what you have.
Drilling the burner ports in the proper locations & sizes will be a bigger challenge, IMO.
