NOx
Sealed Top Panel
The sealed top panel
protects boiler controls
from spills or leaks;
the components are
also isolated from the
lower jacket to protect
them from cold or moist
combustion air
Single Point Power
Boiler pump and DHW
pump are powered
directly from the Alpine
Negative Cabinet
Pressure
Lower portion of the
boiler cabinet operates
under a negative pressure,
creating an additional
layer of safety
Smart Controls
Display panel shows
control status, settings
can be adjusted with
soft-touch buttons
Control panel slides out
for easy servicing
Easy To Move
and Install
Jacket sides are equipped
with flush mounted carry
handles. Jacket bottom
features nylon glides
Efficient Combustion
Air and fuel are pre-mixed
in the blower assembly
for clean, balanced
Simple Connections
All gas, water, and
electrical connections
are made from the left
side of the boiler
combustion
Design Simplicity
Separate spark rod and
flame sensor are used for
longevity and reliability
Condensate
Protection
Unique polyproplyene
condensate trap (patent
pending) stands up to acidic
condensate, and features an
integral float switch which
protects the heat exchanger
from back-up
Long Lasting Comfort
Durable, efficient stainless
steel heat exchanger
maximizes heat transfer
American-Made Quality
Alpine boilers are designed
and assembled in Lancaster,
PA. Each Alpine is hydro-
tested and fire-tested in
order to deliver safety,
efficiency, durability
Venting
Alpine comes standard with a CPVC/PVC
vent kit. This ETL-approved material consists of a
30” CPVC starter pipe and one 90° CPVC elbow.
and low emissions.
