Vent Damper wiring question

I am considering buying the Hydrolevel 3200, however the vent damper wiring has me puzzled. The Hydrolevel has a 6 pin Molex connection whereas my vent damper has a 4 pin Molex.

I emailed the company asking for a schematic but they have not responded.

I am also curious about this note from the installation manual.

NOTE: Once a vent damper plug is
connected to the HydroStat, the control
is permanently altered and will no
longer function when the vent damper
plug is disconnected.

What aquastat is currently installed?

Your damper is plugged into the aquastat now?

What are you curious about?

It's a safety feature. If the unit is installed on a boiler with a vent damper, that feature prevents someone from unplugging the damper and putting the jumper plug back in and firing the boiler with a closed damper and killing themselves and their family by carbon monoxide.

Vent damper wiring question

The vent damper is currently connected to a Honeywell R8285D.

Your explanation about the vent plug makes sense now.

Thank you for that.

If you are only replacing the aquastat, you can leave the vent damper wired just the way it it.

Leave the 'jumper' plug installed in the new aquastat.

Vent Damper wiring question

So you are saying that by wiring the burner circuit to the Hydrolevel it will include the vent damper wiring----Got it!

Thanks

I think that's what I'm saying!

Let's be clear though...

If your damper is currently wired to something OTHER than the existing aquastat, then when replacing the aquastat with a different model, you do not need to do anything at all with the damper wiring.

You will leave the jumper plug installed on the new aquastat, and the damper wiring as-is.

Vent Damper wiring question

The vent damper IS wired to the existing burner control (R8285). I should be able to remove the wires from terminal R and C of the R8285D and connect to them to B1 and B2 of the 3200.

Wait....

No, that sounds absolutely INCORRECT!

Tell me what make and model boiler this is.

I'm suspecting it's a Weil-McLain product, is that correct?

You may not be able to install that 3200 on that boiler without significant rewiring.

Don't but that 3200 yet...

No its a Smith GB100w with continuous pilot. I haven't purchased the 3200 yet.

I want to be sure that it will work plus I need for the weather to get a bit warmer.

No, sorry, short of highly modifying and rewiring the boiler, you can't use the 3200.
