Vaporstat Setting & Boiler Operation

Dave_23

Folks,

In my vapor system, I will be substituting a L408A1132
vaporstat for the stock pressuretrol.

It was recommended that I start with the following vaporstat settings: Cut in at 4 oz, Differential at 6 oz.

Given that this is a subtractive type device, is the following operating profile correct:

Upon call for heat, the boiler steams to a maximum of 10 oz pressure, at which time, the boiler shuts off. When the steam pressure drops to 4 oz, the burner refires. All this is assuming that the thermostat is continuously calling for heat.

Correct?

yes

see if all of the radiators still get hot and if so, that's all there is to it.
