Figures from each model’s own manufacturer documentation (spec sheets and manuals); runtime = documented tank capacity ÷ consumption at 50% load. Verify against the datasheet for your exact configuration.
Across 9 models with manufacturer data, full-load consumption runs 0.48–3.60 gal/h (median 1.30); at 50% load the median is 0.87 gal/h.
