Jotul GF 600 firelight direct vent installed...BUT

[DavePa]

Finally finished the instal using a horizontal termination.

converted from Propane back to NG...Pilot light lit...

But can not get the main burner to fully light. Just a little splash of flame from the front tube.

Now what?

 

[DavePa]

Is it possible to have incorrectly installed the parts for the NG conversion?

 

[Ironhorse74]

Spider Web in the burner tube?

 

[DavePa]

Reading .679 milivolts at the board

 

[DavePa]

Checked all tubes and lines for blockage... none found
indications are leaning to defective gas valve

 

[Ironhorse74]

Check input gas pressure and outlet gas pressure. I have never in 35 years seen a valve fail like that.

 

[DavePa]

Had no way to check pressures this evening. Did however try to adjust pressures , counting turns made to bring it back to settings, with no changes.

 

[Ironhorse74]

It could be a bad regulator, but without a manometer we are just guessing.

T'ed off the gas line to my Natural Gas furnace

 

[DavePa]

Strong flame at pilot light..just not beyond

 

[Ironhorse74]

Bad regulator on the valve. The part that turns the flame up and down. You did change it, when you converted from LP to NG?

 

[DavePa]

When checking voltage at block I have 679 ML when thermopile is disconnected, 260 MV when connected. Is it eating the voltage trying to activate the valve?

 

[Ironhorse74]

That sounds normal. Did you change the regulator on the valve?

Yes i did change it, It was changed to propane by previous owner, who never fired the stove. I then mad the conversion back to NG

 

[Ironhorse74]

With a new regulator? Is the valve a 820 Nova SIT?

 

[DavePa]

That sounds normal. Did you change the regulator on the valve?

Yes Regulator, Pilot orifice, burner orifice, gasket, spring,

 

[Ironhorse74]

I think your problem is in the regulator.

Im not sure
the only markings i can see on the bottom of the valve body is 20BI, maybe

 

[DavePa]

I think your problem is in the regulator.

Can I just purchase the regulator
I don't see that in the parts list

 

[Ironhorse74]

Does it look like this? (broken link removed to http://woodheatstoves.com/images/P1040333.jpg)

Yes
the one removed looks the same my code number is 0907202

All right it is an 820 NOVA SIT. I can't remember how the NG regulator installs. There is a rubber diaphragm and a spring. We're there directions?

There are, but it shows going from NG
Says nothing about going to NG Just a photo removing

If you can hear the gas valve "CLICK" when you turn the unit on, the valve is trying to supply gas to the burner.
Pull the burner, remove the burner orifice with a 1/2" (or13mm) box wrench or socket & see if the tube behind the
orifice is blocked by a spider's nest... It'll look like a white diaphragm across the ID of the gas line.
This happens a LOT. A Q-Tip or a pipe cleaner will clear the nest. Reassemble & give it another try.

Did all the above, no blockage found.
Do NOT hear the click when trying to fire up... Do get a click after pilot light has been shut down.
