1.
Listed Output is at the guaranteed minimum efficiency of 81%
2.
Stainless Steel Heat Exchanger is Standard for Modulating Gas Heat Options Only
.
3.
Stainless Steel Heat Exchanger is Standard for all Gas Heat Options.
Note: Ratings shown are for elevations up to 2000 ft. For higher elevations see
Table 9 or reduce input by 4% per 1000 ft of additional altitude. In Canada, the input must be derated 10% for applications
2000 to 4500 ft in elevation. 1. High Fire (Stage 2) output is at the guaranteed minimum of 81% efficiency
.
2. Low Fire (Stage 1) output is 55% of High Fire output except for EVT
-12, which is 65%.
3. Low Fire (Modulating) output is 20% of one half the High Fire output.
