2 - LOCATION OF THE UNIT
ModelFCXisafreestanding(floormounted)appliancesuitable
for installation on combustible flooring. It is approved for
installation with zero clearance to combustible walls, ceiling,
doors, etc from the cabinet. Standard option coaxial flue
components are suitable for installation with zero clearance
to combustible materials.
These are operating clearances and it is recommended that
additionalclearancesbe considered:
• Sufficientclearanceshouldbe provided in back of the unit to
facilitate installation and maintenance of water, electrical,
flueand condensate drain connectionsand components.
• Sufficientclearanceoverthetopoftheunitshouldbeprovided
toallow the topto be removedfor service.
• Sufficientclearancefrom the front of the unitshouldalsobe
providedto facilitate adjustments and service.
There is no need for additional clearance to either side of the
unit since there is no access to the unit from either side.
Alternative access measures such as doors, removable wall
panels, etc. may be provided if desired.
Choosing the location should also take into account the total
fluelength totheoutdoors(SeeFlue ConnectionandRouting).
Inaddition,thechoice of location should consider the location
of utilities such as electrical supply and sewer access for
condensate drainage. Location and routing of water lines is, of
course,asignificantpartofthechoice.WhileModelFCXcanbe
installed in an enclosure such as a closet, ventilation or other
meansmustbeprovidedsothattheenclosuretemperaturedoes
not exceed 113 deg. F (45 deg. C).

OPERATION
3 - FLUE CONNECTIONS AND ROUTING
Connection of the coaxial flue/combustion air piping system
is in the back of the unit to the separator tube assembly. The
combustion products are vented from the heating system and
condenser through the center of the coaxial tube, while the
combustion air is supplied through the outside ring of the
coaxial tube. Since the FCX is a condensing heating system,
flue products exiting the unit are relatively low temperature,
typically from 120 -212 ° F (49 -100 ° C), and saturated with
humidity. Consequently, an airtight, corrosion resistant flue
systemmust be provided.
Variousstandardoption flue pipingcomponentsand packages
with which to create the flue system are available.

INSTALLATION
4 -ALTERNATIVE FLUE CONNECTIONS
All combustion appliances consume a quantity of air
proportionaltotheircapacity.If unit is installed using inside
make up air, ventilation louvers must be installed in
confined areas according to code. Toavoid corrosion, the
combustion air must not contain any harmful agents.
Halogenated hydrocarbons, containing combinations of
chlorine or fluorine that are found in solvents, paints, glues,
propellants,household cleaning products,etc.
TheFCXheatingsystem is acondensing heatingsystem,which
means that the combustion products from the appliance are
discharged at low temperature(120° to 212°F) and saturated
with humidity. Consequently, an airtight, corrosion-resistant
fluesystem must be provided.It is possible touse an existing
flueas long as it is lined. Thelining must beinserted so that it
doesnot retain any condensateandso that any condensates
are transferred to a drain located at the foot of the flue or
directly back to the heating system condensate trap. The
materialfor the lining must bechosen specifically for use with
a condensing heating system. Suitable materials certified for
use in such combustion product systems are 904 L stainless
steel,PPSpolypropylene, and PVDF.Specializedcompanies
market these systems and indicate the tubing assembly
proceduresto be applied.

3 - ADJUSTING THE OIL BURNER
Whilethe oil burnerleavesthefactoryset at therecommended
settings, safe operation requires that the burner be checked
and adjusted by a qualified, licensed if required, oil service
technician using properly calibrated combustion test
equipment, vacuum and pressure gages.Run the unit long
enough at the burner maximum firing rate to make sure the
burnerhas reached a stablemaximumoperatingtemperature.
THEN, check the burner and adjust as follows:
Check to determine that the smoke spot number does not
exceed 0.5 with a Bacharach or equipment tester control.
Adjust the burner as required to be below this maximum.
Checktodeterminethatthe CO2 rate is from 11.5 - 13 percent
andthatthereisnoCOproduction.Adjusttheburnerasrequired
to achieve this operating characteristic.
Measure the temperature of the flue gas exiting the unit to
determine that it does not exceed 250 degrees F (120 C).
Combustioninspection can be carriedouton the unit through
the hole (item N) provided in the inspection port (item 7). Be
sure to replace the washer (item M) and the test point screw
(item6) properly after inspection.
4 - CHECKING THE SAFETY DEVICES
At the time of start-up, check the safety and control devices
as follows:
Thermostats:
• Check to see that the thermostat bulbs are correctly
positioned in their housings. This is essential to provide
temperature sensing to facilitate burner shutdown in the
event of overheating,
Flame monitoring:
• Check to make sure that the burner shuts down properly
upon the deactivation or disconnection of the flame
monitoring device or interruption of the flow of fuel,
Safety Pressure Relief valve:
• Checkthe safety pressure relief valvein the heating circuit
for proper operation.

4- ADDITIONAL COMPONENT MAINTENANCE
Check to see that the safety and regulation devices (safety
reliefvalve,air bleed valve, control box components,etc.)are
operating properly. Check that the condensate drain trap is
clean. If necessary, remove the bottom of the trap, clean it,
replace it and then refill the trap it with water. Also check to
see that neither the installation nor the heating system have
any water or fuel leaks (leaks may produce a risk for safety
andshortenthe life-span). If it becomesfrequentlynecessary
to add water to maintain pressure in the installation, even
thoughnoleakshavebeendiscovered, perform an expansion
tank check or if the pressure releif valve drips or pops
occasionally.
5- EXPANSION TANKPRE-INFLATION PRESSURECHECK

During the course of seemingly normal operation, there may
be operating faults experienced in the system. Some of the
more common faults that may be encountered are:
BURNERFAULTSHUT-DOWN
Theburner may shutdownforany ofseveralreasons,atwhich
point the burner safety device light (red) on the control panel
will be ON and the there will be a green fault indicator light lit
ontheoilburner. This may be caused by a loss offueloil(tank
empty?), a fouled oil spray nozzle in the burner, or perhaps a
fouledorfaultyflamesensor.Toattemptarestartaftercorrecting
any burner problem and the fuel supply is assured, push the
resetbutton on the burner.The burner shouldrestartafterthe
preset time delay period expires.
OVERHEATINGSAFETYTHERMOSTATSHUT-DOWN
Openingof either theWaterOverheatingSafetyThermostat or
theCombustionProductOverheatingThermostatwillresultin
anoil burnershutdown.Ineither case, theburnersafetydevice
light (red) on the control panel WILL REMAIN OFF, and the
green fault indicator light on the oil burner will REMAIN OFF.
The only way to tell if either device has opened is to check
electrically or check the position of the reset button, located
underthescrew cap over each device.
• TheWater Overheating SafetyThermostat may open if the
water temperature exceeds 230°F (110°C) in the heating
system. This can occur if the water temperature control is
near its maximum setting, and or the three way valve is
