Test External Limits
Test any external limits or other controls in accordance
with the manufacturer's instructions.
M.
Check Thermostat Operation
Verify that the boiler starts and stops in response to
calls for heat from the heating thermostat and indirect
water heater thermostat. Make sure that the appropriate
circulators also start and stop in response to the
thermostats.
Adjust Supply Water Temperature
N.
As shipped, the heating and indirect water heater set
point supply temperatures are both set to 180°F. If
necessary, adjust these to the appropriate settings for
the type of system to which this boiler is connected. See
Section XII "Operation" of this manual for information
on how to do this.
O.
Adjust Thermostats
Adjust the heating and indirect water heater thermostats
to their final set points.

Field Conversion From Natural Gas to LP Gas
Alpine Series boilers are factory shipped as Natural Gas
builds. Follow steps below for field conversion from
Natural Gas to LP Gas.

This conversion should be performed by a
qualified service agency in accordance with the
manufacturer's instructions and all applicable
codes and requirements of the authority having
jurisdiction. if the information in these instructions
is not followed exactly, a fire, an explosion or
production of carbon monoxide may result
causing property damage, personal injury, or loss
of life. The qualified service agency is responsible
for proper conversion of these boilers.
conversion is not proper and complete until the
operation of the converted appliance is checked
as specified in this manual.
WaRning
These instructions include a procedure for
adjusting the air-fuel mixture on this boiler.
This procedure requires a combustion analyzer
to measure the CO
2
Monoxide (CO) levels in flue gas. Adjusting the
air-fuel mixture without a proper combustion
analyzer could result in unreliable boiler operation,
personal injury, or death due to carbon monoxide
poisoning.
1. All Alpine boiler models can be converted from
Natural Gas to LP Gas.
2. Conversion of Alpine Series boilers from one fuel
to another is accomplished using the throttle screw
on the gas valve. Figure 53 shows the location of
the throttle screw on the Dungs valve. Locate the
throttle on the boiler being converted.
3. If conversion is being made on a new installation,
install the boiler in accordance with the installation
instructions supplied with the boiler. If an installed
boiler is being converted, connect the new gas
supply to the boiler, check for gas leaks, and purge
the gas line up to the boiler in accordance with
the National Fuel Gas Code (ANSI Z223.1) or the
requirements of the authority having jurisdiction.
