Connection Options
• Space saving tank design –
maximizes installation adaptability
by offering models with front side
and rear side inlet/outlet water
connections. Short heights and
small jacket diameters result in
greater installation flexibility.
• Patented multi-flue tank design
–
proprietary steel formulation,
patented multi-flue design, and
two coats of high temperature
porcelain enamel to maximize
corrosion resistance result in a
superior heat exchanger design.
• Low profile automatic flue
damper –
low profile design minimizes over-
all product height. Heavy duty vent
hood supports are designed to
withstand rigors of installation.
• Specialized burner
assembly –
each model features five premix
burners mounted into a metal face
plate and sealed with a Viton
gasket. Patented “quick release”
manifold for easier service.
• Spark-To-Pilot ignition system –
Standard on all models. Provides
reliable and energy saving ignition
sequencing by igniting the pilot
only when the thermostat calls
for heat.
• System Sentinel
™
LED
diagnostic system –
Our exclusive diagnostic system,
with glowing LED lights, verifies
system operation sequence
by sequence.
• Full port, full flow brass drain
valve
