5 - refractory ring with the Kaowool gasket
6 - the blower motor/fan and the air damper assembly
7 - the burner housing that bolts to the boiler
8 - the control cabinet

Now I understand about the fireclay being packed around the refractory ring.
How well does it stand up being two pieces verses hand packed refractory?

9 - the burner hung, right side
10 - the burner hung, left side
11 - the control cabinet base supports, welded out with 3/32" E6011C
12 - the remote oil pump mounted

13 - the oil heaters, propane pilot and #6 oil regulators
14 - the drive motor, oil valves, air lines
15 - the 7-1/2 hp blower motor
16 - the air compressor mounted, in the lower left corner of the picture

In the furnace, the fire clay stands up better than castable refractory, if packed tightly, almost as good as fired refractory tiles.

In Post #53 picture 12 is that the old ID Fan that is no longer used?

I can see that a factory cast would probably be better in you don't have to rely on someone to get the throat close to specs.

Dang, that looks to me like left & right are reversed.

Is the 7.5hp motor single or 3phase?

Yes, I have to still use the original ID fan, but at a much slower/lower rate

The factory sends the refractory ring, to ensure the interior angle is correct, to make sure the air flow is in the right pattern, if the angles are off, its almost impossible to get it to burn correctly

Hey!!, Its been a long day, I'm tired, yes they are backwards, I've gone back and corrected the screw up.

The motor is 7-1/2 hp, 3600 rpm, 208/230 vac 3 phase, the fan is directly mounted to the motor. Later when I go to start it up, I post pictures of the air damper and the fan.

ok, and good.
That was causing me to have visions of Shadrach, Meshach, and Abednego, thinking you must have to view the burner from inside the boiler to establish right & left.

Jack, I don't care how much they pay you, I think you're underpaid.
You get more done in one day than anybody else I know.

Jack,
Now this ain't about you, or your workmanship,
it's what the customer bought. So I've got a couple
of questions.

That air compressor
and the oil pump look really cheezy.

Why a open frame motor on the oil pump ? Looks like
the area is pretty dirty, and that motor will get filled
with the dirt.
And why not a direct drive ? the belt looks
like a maintainance problem as well.

That aluminum compressor is supposed to run all the
time the burner is ? Looks like a low time, homeowner unit,
and the plastic over the fan looks to be a future head-ache.

Again, I'm not complaining, just wondering, as I don't get around to
see these kind of thing's, but the reliablility looks low.
