Lynx Sedona Rottiserie burner burns too hot - HELP! Checked the LP orifice. It is correct #56 short.

yes sounds like you missed the oven burners at the bottom of unit

What does "and parts to burners" mean? it sounds like you have NG orifices on a LP appliance or the LP orifices are not properly drilled. I use my barbecue several times a week and exchange an LP cylinder about every 6 months. If you are using the grill twice and the cylinder is empty that is not a lot of burning, that is a leak.

to adjust the burner the first and most obvious place to look is to check the pressure on the regulator (LP is 11") and the orifices. Next are there adjustment screws inside the valve stems? if so light the barbecue so the flames are visible and insert a long flat-head screwdriver to adjust the set screw inside the valve stem. turn the valve to "low" and adjust it until the flames are just barely staying on. Leave the set screw in that position and turn the valve on high, close the lid. if you're over 400 degrees in 10 minutes you'll be fine. if not adjust the set screw up a quarter turn at a time.

Unit goes under sure heat name also.
My unit emitted unburnt gas smell the minute pilot started,
and was annoying during burner operation.
I discovered they built unit with primary pilot that had 2 ports.
They used LP and sealed off natural gas,instead turning lp/nat
knob on back activates second pilot for natural gas use.
This means natural gas goes thru LP pilot orifice and burns
slightly off during normal natural gas use(by design).
The unused natural gas orifice has 1 air mix hole and the LP orifice
has 2 air mix holes.
I carefully plugged 1 of the holes in the LP orifice and suddenly
pilot gas flame seated correctly on orifice port.Gone was the
unburnt odor of natural gas.
The typical flame in a flame appearance now was exhibited by
the small pilot,secondary pilot remained consistent with manual
picture.
Of course, to use with LP I would have to open blocked air mix
hole in addition to the other changes per manual.
Hope this helps someone with similar condition.

Burner orifices must be resized or adjusted to accommodate higher pressure LP.
Air shutters should be opened all the way to allow maximum air to gas ration.

check the burner orifice and gas valve spring kit if it is suited for propane use.remove carbon build up inside the fire tubes.check also if the gas pressure is correct.

you will will have to change the reg as ng burns at 4inches and lpg burns at 14 inches and pilot orffice if fitted

First things first. Make sure you didn't simply just the tank valve on too fast, causing the excess flow valve to cut-off gas to a trickle. Close tank valve, disconnect and reconnect and then open tank valve very slowly.

If that doesn't solve the issue, seeing that you already replaced the regulator, then it's possible it wasn't converted properly. If he didn't change the orifices, leaving in the nat gas ones, then your flames would be large lazy yellow flames. If that's not the case, then it's possible he might have put in the incorrect size LP orifices based on a wrong figuring of BTU rating per burner. See if you can you find the BTU rating on the grill? How many burners are there? Does it state the BTU rating of each burner. If they are different sizes we will need to know BTU specifics for each burner, but if all are the same size, we can divide the total BTU by the # of burners for BTU rating per burner. Orifices have a # stamped on them, so see if you can read the #'s on the existing orifices. If he used the nat gas orifices and drilled them larger and installed a spud, which he redrilled for LP orifice size, then that stamped # won't matter. Something like this is a lot easier to trouble shoot in person! Using a small mirror, see what you can figure out on those orifices and we'll try to determine if they are correctly sized. Hope this helps.

MAKE SURE THE BURNER TUBE AND ORIFICES ARE CLEAN. MAKE SURE YOU HAVE THE PROPER LP PRESSURE.

Did the kit come with NG orifices and did you use them.

Are you using natural gas or propane (LP)? It sounds like you may need to change the orifice size on the gas lines going to each burner. If you are using LP and have the orifice set for Natural gas, the flames will burn higher and hotter, causing heavy soot. Under each burner, there should be a small nut with a hole in the center at the end of the gas line. The hole for Natural gas has a slightly larger diameter than one for LP. Your stove should have come with extra orifices as part of a conversion kit. Could this be the case? There's also another orifice in the main gas regulator in the back of the stove. Have you checked to see if the orifice for the regulator is set correctly? Does the oven burn hotter than usual with heavy soot, too? If you could please answer these questions first, I can give you better advice. Let me know...
