Fossil fuel heating
equipment
principles and troubleshooting
techniques
This application note was written
to provide you with an understand-
ing of the basic principles of fossil
fuel heating systems and how to
troubleshoot these systems using
thermometers, digital multimeters
(DMMs), clamp meters, pressure/
vacuum modules and other acces-
sories. Heat pumps and forced air
electric heat furnaces are discussed
in other application notes available
from Fluke.
Heating systems
principles
Forced-air heat is generated at
a central furnace and is then
distributed and delivered to the
conditioned space via a duct
system. A properly designed
heating system will generate
quiet, filtered, and comfortable
air into the conditioned zone.
Modern systems have been
recently designed that will also
filter the air electronically, modu-
late airflow as zone temperatures
change, and bring in fresh outside
air based on occupied time.
fuel heating systems predomi-
nantly available on the market
today. These include natural gas,
liquefied petroleum (LP) and fuel
oil forced-air furnaces.
Fossil fuel forced-air
heating
Forced-air fossil fuel furnaces are
factory manufactured, packaged
heating units that include:

There are three types of fossil

Newer units often include a
secondary heat exchanger to
increase efficiency and an auxil-
iary fan for combustion gases.
Since the newer units substan-
tially cool the combustion gases,
removing water vapor from the
combustion gases, they often are
called condensing high-efficiency
furnaces. Additionally, they
will have plastic flue gas piping
instead of older more traditional
metal flue pipe since the gas
temperatures are much lower
than less efficient older units.
