FOGATTI Instagas 170 LP
The Fogatti InstaGas Classic (FDG-CF170W-LP) is the CSA-certified indoor propane model in Fogatti's 170,000-BTU line — 7.5 GPM maximum, non-condensing, and notably powered by a standard 120 V AC outlet rather than batteries, which suits a permanent indoor install. Servo temperature control keeps output within ±1 °F, and the unit carries the CSA listing many jurisdictions want for code-compliant indoor propane installation.
It shares the same core hardware — and the same trade-offs — as the rest of Fogatti's 170 line: strong BTU for the price, but a mixed reliability record (about 3.6 stars across ~89 owners) and non-condensing efficiency that trails condensing units. The 120 V AC requirement is the main practical difference from RV/off-grid Fogatti models: it needs an outlet nearby. For a budget indoor propane heater with a proper safety listing, it's a reasonable pick — provided you weigh the softer reliability track record and can supply full 170,000 BTU/h.

FOGATTI Instagas 170 LP FAQ
What makes this the 'Classic' vs other Fogatti 170 units?+

Yes — a standard 120 V AC outlet near the heater. Plan for a receptacle within reach during installation.
How reliable is it?+
It averages about 3.6 stars across ~89 reviews — a mixed record typical of budget propane tankless. Great value when it works; weigh that against mainstream brands if dependability is paramount.
