Philco Heat Exchanger Rollout

[kkheating]

Installed new H/E, now having problem with flame rollout when fire box cover is installed. Run without cover and flame dose not rollout but looks yellow. Removed intake pipe from furnace and still have problem. Please Help! Thank you.

Looking for suggestions. Have checked: Venting, Gas pressures, Orfices, Replaced inducer blower assembly and gasket, Replaced limit at firebox, Spoke with nordyne tech.

Since none of us really know what "checked everything" is.
And you didn't post any readings. We can't even begin to help.

Damn! I have a 1941 Radio made by Philco, and a beautiful piece of work it is... Is this what they make nowadays???

Sorry for OT....

How is that seal at the top of the hx and the top plate? Burners sitting at the top of the furnace don't like air leakage from the blower.

Thanks for the help, Im going to the house today and will check seal and then post readings.

Philco M/N G6RC120C20C
LP Gas pressure @ 10.25"
Firebox sealed, cleaned burners, checked & sealed ID blower, inducer pulling 2"wc at burner box and 2.5"wc at collector box. Orfices in are #54 tech says should be #55, could this be a problem?
Furnace still having flame between burners increases and touches inside of burner box when fire box cover is on, when removed operates rich but flames are proper size.
What next?

You need a better tech/installer.

Have your tech cal factory tech support, and perhaps get a factory rep out.
The installing contractor can have this done without much trouble or delay.

Thanks for your lack of advice...Been there done that...meaning spoke to a factory rep and they basically walked away. We did not install the unit but only trying to correct the issues. We'r only looking for a little advice, sometimes a new opinion can help.

Then call and arrange for the tech rep to come out.
