NOTE: All gas units are two-stage heating.
First stage is 50% of total.
S.S.E. = Steady State Efficiency (80%) - output divided by input.

1. These values have been accessed using a model of sound propagation from a point source into the hemispheric\free field. The
dBA values provided are to be used for reference only. Calculation of dBA values cover matters of system design and the fan
manufacture has no way of knowing the details of each system. This constitutes and expectation to any specification or guarantee
requiring a dBA value or sound data in any other form than sound power level ratings.
2. At a distance of 10 feet from the blower.

2. EER = Energy Efficiency Ratio at full load - the cooling
capacity in Btu’s per hour (Btuh) divided by the power
input in watts, expressed in Btuh per watt (Btuh/watt).
