Burnham PVG

The PVG is U.S. Boiler Company's side-wall-vented cast-iron gas water boiler, published on the official site as 'Gas, Water — Cast Iron Heat Exchanger' with an 85% Efficiency badge. The product page describes it as built on the same platform as the ES2 and designed as an optimal replacement boiler for homes without existing chimneys, venting directly through the side of the house; it lists natural or LP gas, high-quality boiler control components, a time-proven cast-iron design, a limited lifetime manufacturer's warranty, optional 5- or 10-year parts and limited labor warranty plans administered by CornerStone United, and the IHC Boiler Control System.

The official archive card for the PVG adds that it blends 'unmatched performance with long-lasting durability and exclusive energy saving features' and that at its heart is one of the most advanced cast iron heat exchangers in the industry with a well-insulated heavy-duty steel base for longevity. The product page posts no I&O manual or printed rating table, so Boilers.ca records the series at hub level with the page's printed 85% efficiency headline; no per-model rows are published because no official printed rating rows are reachable.

U.S. Boiler Company also publishes an 'Important safety information for models ESC, SCG and PVG boilers' page, which owners of installed PVG units should check. No official Canadian-sales statement was found, so canadianStatus stays 'unknown'; service belongs with a licensed contractor against the documentation for the specific unit.
