ƒ Snow
Melting
High Efficiency
Heating efficiencies meet or
exceed NAECA standards.
Factory Installed Circulator
and Bypass
Thermostatically-controlled
circulator maintains proper flow
through the boiler. As a packaged
system, installation is fast and
easy.
Electronic Ignition
Intermittent pilot ignition improves
system efficiency by using fuel
only when there is a call for heat.
Compact, Lightweight Design
Even the largest model slips
easily into tight spaces.
Easy to Plumb, Easy to Service
Inlet and outlet water piping, gas
connection, wiring and controls
are all up front for easy access.
Safe Operation
Built-in manual reset safety
sensors shut down the boiler in
the event of a flame roll-out or
flue gas spillage. Normal working
pressure is 125 PSI max.
Fast Response Temperature
Sensor
Electronic solid state auto-reset
control shuts down the boiler in
the event of over-heating caused
by a low-flow condition.
