The PROBLEM is that it's like oil nozzle sizes, there is no "national standard".
I would just talk to "tech" at Heat Controller.

Ok, here is what I found out:
A #54 drill is .055 inch
An 16 gauge wire is .051 inch
A 16 gauge wire fits very nicely through the #54 orifice.
Now, this could be a coincidence or it could mean that
these orifices are sized just like standard drill bits.
Assuming the above:
The #42 orifice that I need coincides to .0935 inches.
A 3/32 drill bit is .0937.
.0937 is right in-between a #41 and #42 drill.
I don't have a drill set with numbered sizes. Tomorrow
I'll see if I can buy a few #42's. If not I may just use the
3/32. I believe that should leave me enough range to
adjust to a blue flame.
This is making me nuts /forums/images/graemlins/confused.gif /forums/images/graemlins/mad.gif

Fact is you can "correct" the current problem now (valve and orifices) and the furnace may be fine for the next 10 years.
But...if it is this much trouble just to get a gas valve (what are you looking at so far, 3 weeks or more?), you run the chance of having the same availability on other parts as well.
Problem is you "usually" only run your furnace when you need it (when it's cold out).
Say in December you need a limit switch or ignition control board (or pressure switch). You want to run the risk of having to wait that long for a "common part"?
Considering the unit is over 10 years old and from the current "issue" on parts, get a new furnace.

When I drilled out some orfices had a hard time getting drill bits small enough. Finally found some that came in pencil type case that also acted to hold the drill bit as you hand drilled the orfice. Was very easy drilling. Hardest was trying to see what the bit size was.
Hope all goes well.

Ok, folks, good news . . . I have an operable furnace /forums/images/graemlins/grin.gif I had help from several TBN'rs but one in particular spent some time on the phone with me. He instructed me as to how to do some checking and calculating and drilling. Result, I have heat /forums/images/graemlins/cool.gif If the TBN'er would like to be recognized, here is your chance to take a bow. (or fade into obscurity, your choice.)
I clocked the meter and found that I'm actually running a bit under the rated capacity of the furnace but the flames are nice and blue, no CO2 emissions reported by either of my NightHawk detectors.
In a week or two, when my parts arrive, I plan to install the original equipment parts. Till then, I'll be keeping a close eye on the operation of the furnace.
Ok, here is the interesting part. I have participated in many friendly debates here on TBN about whether one should drill their ROPS. I drilled holes in mine to mount my lights. I have been roasted by many and admired by few. Drilling must be in my blood, for I feel I'm about to be roasted for drilling again. Except this time, it was gas orifices and not a ROPS.
