Q This large water content boiler
installs in difficultsteam or water
applications.
o AFUE ranges from 76.8%
(standing pilot) to 80.7% (spark
ignition) on steam boilers and
80,3% to 81.7% (spark ignition
only) on water boilers, significantly
exceeding the federal standards
for residential boiler efficiency.
o Low profile design ideal for boiler
installationsin areas with a low
ceiling.
An optional tankless domestic
hot water coil can be installed on
hot water boilers, insuringample
domestic hot water production.
o Probe or float-type low water
cutoff available.

3 Consult factory before selecting a boiler for installations having unusual piping and pickup requirements, such as intermittent system operation, extensive piping
systems, etc.
4 Heating Capacity and Annual Fuel Utilization Efficiency (AFUE) ratings are based on U.S. Government test. Before purchasing this appliance, read important
information about its estimated annual energy consumptions or energy efficiency rating that is available from your retailer.
