2007 installed Burnham V84 boiler, rotted on one section and starting to corrode on the others. He decided to convert to gas, we installed a Union Steam GSA 125,000 (EG40) I’m also going to put a two stage gas valve when my parts arrive. Totally finished basement so we had to snake Wardflex through the rafters to get gas to the boiler, all went well, but was back breaking job.

    Beautiful, @Dave0176! Why 2 stage it? Are there zone valves or TRVs on the rads?

    No, it’s to modulate the fire to maintain between 4-10 oz steam pressure. Starts on high fire as pressure rises in the system when it reaches 10 oz the Vaporstat kicks the fire to low.

    @Phil53 Ward Flex is Wards version of flexible gas line aka CSST (corrugated stainless steel tubing).

    Ahh, got it. Thanks!! I didn't think it was needed on properly sized boiler. We have it and does great with zones. When all are calling, never above 8 oz. With 1 zone closed, modulates at 8. Super nice. I suppose I never thought to modulate even with all zones calling. I'll play with that this winter.

    I think there's a good argument that you size for load & a healthy 50% pickup, but then down fire just to match load only... plus you could use a few TRV's for rooms with varying heat loses or small sizes like kitchens and bathrooms.

    How much pressure you need is then just a matter of the size of your header relative to the boiler size and size of your vents.


    Beautiful install. Like the 2 supply's to the header. It's not a large boiler but I'll bet the steam is nice and dry with the extra pipe.
