flame failure

I have a Heatilator mod # ND4236L propane f/p pilot stays lit but turning on the f/p shuts down the whole system after 2-3 minutes. Have repalced the thermocouple, checked voltage from the thermopile (within parameters) still no luck. Thorough cleaning, both vacuum and compr air.

Heatilator really has its act together. Very good service info at their site. I've left you a link to your insert. Look down in the page 50 area for diagnostic steps.
