2.2 Specifications

2.2.1 Boiler - Burner Modules, Efficiency, Flow Rate, and Water Connections

Each AM Series pool heating system includes a boiler featuring from 2 to 4 thermal modules,
depending on model, performing total turn down ratios without loss of combustion efficiency as
shown in the table below. Each thermal module's premix burner is a metal fiber mesh covering a
stainless steel head, with spark ignition and flame rectification. All burner materials exposed to
the combustion zone are of stainless steel construction. There are no moving parts within the
burner itself. The burners produce <20 ppm of NOx corrected to 3% excess oxygen. A modulating
gas valve, and variable speed fan, meter the natural gas and air input, respectively.
Each module has a dedicated isolation valve on the inlet side of the module on the rear of the
unit. The table below shows the pool flow rates for each model, as well as the water connection
sizes.
