A.O. Smith GPVX-50L ProMax SL Power Vent Specifications
Researched from the DOE test procedures, NFPA 54 and NEC code tables, and manufacturer specifications. Updated .
Quick answer
This page collects what is actually published about the A.O. Smith GPVX-50L ProMax SL Power Vent and shows what those figures produce, computed rather than transcribed. Anything the listing does not publish is not filled in with an estimate.
Published specifications
Everything here is taken from the listing or the manufacturer, and nothing is inferred.
| Specification | Value |
|---|---|
| Gallons | 50 |
| Fuel | Natural gas |
| Vent Style | Power vent |
Published standard Source: Manufacturer listing data. A specification not listed here is one this listing does not publish. Check the installation manual for the full data plate.
Why there is no performance table on this page
This listing does not publish an input rating in BTU per hour or in kilowatts, and without one there is nothing to compute a flow rate or a recovery rate from. Estimating it from the price or from the physical size would produce a confident number with nothing behind it, so this page does not.
The installation manual for this model publishes the input rating on its data plate. Once you have that figure, the recovery rate calculator and the tankless sizing calculator will do the rest.
How it sits against the rest of its category
There is a full review of the A.O. Smith GPVX-50L ProMax SL Power Vent covering who it suits and who should not buy it.
Other gas storage tanks in this catalog: GE RealMAX Choice 40 Gallon Natural Gas, Rheem PROG50-36P 50 Gallon Propane.
Compare them on input rating and on the figures the manufacturer actually publishes rather than on the headline number in the listing title, which in this category is frequently a maximum measured under conditions the listing never states.
Other gas storage tanks
GE RealMAX Choice 40 Gallon Natural Gas
$1,051.49An atmospheric tank vents on buoyancy alone through an existing flue, which is why it is the cheapest gas tank to install and the one most exposed to backdrafting.
Best for: A like-for-like swap into an existing masonry or B-vent flue

Rheem PROG50-36P 50 Gallon Propane
$1,207.00A 36,000 BTU propane atmospheric tank. The input figure is what sets the recovery rate, and 36,000 BTU is the usual figure on a residential 50 gallon.
Best for: Propane properties replacing an atmospheric tank

- What are the specifications of the A.O. Smith GPVX-50L ProMax SL Power Vent?
- The listing publishes gallons, fuel, vent style and related figures, shown in full in the table on this page. Anything not shown is something the listing does not publish, and this page does not estimate it.
- Is this page based on hands-on testing?
- No, and we never claim otherwise. Everything here is compiled from the manufacturer listing, published specifications and the energy relations that turn those specifications into flow and recovery figures. We do not test products in person. Where a figure is not published, this page says so rather than estimating it.
- Are the prices on this page current?
- They come from verified catalog data at the time the page was built, and prices in this category move often. Treat any price shown as a guide and check the listing itself before deciding. Availability moves even faster than price does on water heater accessories in particular.
A water heater is a pressure vessel. The temperature and pressure relief valve is the one component on it that is never capped, plugged or removed, and a valve that will not open when you lift the test lever has failed and needs replacing rather than ignoring. If the valve weeps after the heater runs, that is thermal expansion in a closed system and the answer is an expansion tank or a pressure reducing valve, never a cap.
