FVO-1100TR SETUP PROCEDURE
The two FVO-400RC heaters in the trailer need to be tested and set up
before every operation. Proper combustion must be achieved using a
certified combustion analyzer and smoke gun tester to ensure optimum
set up. The air adjustment should be made to achieve a maximum of
10% CO2 and No. 1 or “trace” smoke. (Bacharach Scale)
SETTING THE AIR ADJUSTMENT PLATE
A) Regulation of the
combustion air flow is made
by adjustment of the manual
AIR ADJUSTMENT PLATE
(1) after loosening the FIXING
SCREWS (2 & 3). The initial
setting of the air adjustment
plate is set to 4.5 at the
factory.
B) The proper number on the
manual AIR ADJUSTMENT
PLATE (1) should line up with
the SETTING INDICATOR (4)
on the fan housing cover.
Once set, the air adjustment
plate should be secured in
place by tightening SCREWS
2 and 3.
C) The final position of the air
adjustment plate will vary on
each installation. Use instruments to establish the proper settings for maximum
CO2 and a smoke reading of zero.
NOTE: Variations in flue gas, smoke, CO2 and temperature readings may be
experienced when the burner cover is put in place. Therefore, the burner
cover must be in place when making the final combustion instrument readings,
to ensure proper test results.

SETUP PROCEDURE (HIGH ALTITUDE)
When the FVO-1100TR is required to operate over 2000 feet above sea
level there will be necessary adjustments needed to burn efficiently with
thinner air. Please review the following chart as a starting point; please

IF HEATER FAILS TO START:
1. Press manual reset button at rear of burner. (Red button)
2. Check fuel level gauge for sufficient amount of fuel.
3. Make sure there are no air blocks in fuel lines or filter. Bleed lines if
required.
4. Ensure power supply plug is connected properly.
5. Check for dirty fuel filter or blocked fuel supply line.
6. Check burner nozzle assembly.
7. Make sure the burner control box does not need to be reset.
NOTE: IF THE BURNER HAS BEEN RESET SEVERAL TIMES THERE
MAY BE AN ACCUMULATION OF FUEL IN THE CHAMBER! DO NOT
CONTINUE TO TRY AND START THE HEATER!
DRAIN FUEL FROM HEAT EXCHANGER USING DRAIN HOLE AT FRONT
OF HEAT EXCHANGER FOR 15-20 MINUTES BEFORE ATTEMPTING TO
RELIGHT. LET REMAINING EXCESS FUEL BURN OFF BEFORE
CHECKING COMBUSTION OF UNIT.
SAFE OPERATION PRECAUTIONS:
1. Do not fill fuel tank while heater is operation.
2. Do not attempt to start heater if excess oil remains in the heat
exchanger.
3. Use switch to shut down the heater. Do not try to shut down the heater
by unplugging the electrical cord.
4. Do not plug anything other that the thermostat into the “Thermostat”
plug.
5. Do not use any fuel other that those listed on rating plate.
6. Before removing any guards or performing any maintenance, be sure
that the main power supply is disconnected.

MAINTENANCE:
1. Every construction heater should be inspected before each use, and at
least annually by a qualified service person. Incorrect maintenance my
result in improper operation of the heater and serious injury could
occur.
2. The hose assemblies shall be visually inspected prior to each use of the
heater. If it is evident there is excessive abrasion or wear, or the hose is cut, it
must be replaced prior to the heater being put into operation. The
replacement hose assembly shall be that specified by the manufacturer.
3. The flow of combustion and ventilation air must not be obstructed. Be sure to
check the fan assembly and ensure that the motor and blade are operating
properly.
4. Compressed air should be used to keep components free of dust and dirt
build up. Note: Do not use the compressed air inside any piping or regulator
components.
5. Change fuel filter insert (Part# FVO-TLSF) once year.
6. Change oil burner nozzle (Part# FV-435B (2.00 X 60) once per year.
7. Fan Limit Switch (Part# FV-407A) should be replaced if the fan motor does
not shut off after the heat exchanger has cooled down.
8. The High Limit Switches (Part# FV-406 & FV-437) should be checked each
season. These limit switches will ensure the burner shuts down if the
temperature exceeds 150º F at rear of unit and 250º F at the outlet.
9. Fuel tank should be drained on a regular basis by removing drain plug.
10. CAUTION – Do not have any source of ignition near the heater when
draining tank.
NOTE: No.1 fuel oil or kerosene is recommended for temperatures below
-10º C / 8º F.
11. Heat Exchanger should be cleaned if smokey conditions continue even after
the air adjustments on the burner are made.

TEMPERATURE FEELER GAUGE ADJUSTMENT
(ATTACHED TO FAN SWITCH)
The temperature feeler gauge is required to be always touching the heater
exchanger.
The temperature feeler gauge controls the air flow over the fan switch, which
eliminates any unnecessary fan cycling. The temperature feeler gauge can be
adjusted for different outside temperatures, by rotating the location of the
temperature feeler gauge holes. This will provide maximum performance of the
unit in different applications.
If supply air is warm (-5º C, indoor application):
Turn the temperature feeler gauge so that the holes are parallel with the heat
exchanger. This will help the fan switch to remain cool and not overheat. See
following:
If supply air is cold (under -5ºC):
Turn the temperature feeler gauge so that the holes are closed off as the air goes
over the heat exchanger. This will reduce fan cycling and the unit from shutting
down. See following:
In extreme cold conditions, cover the holes on the temperature feeler gauge
using foil tape or use part# FV-433B (solid feeler gauge). Ensure that the
temperature feeler gauge is readjusted for warmer weather conditions. Failure to
do so may result in burning out fan switches- not covered under warranty.

BURNER WIRING DIAGRAM
ELECTRICAL CONNECTIONS
It is advisable to leave the control box off the sub-base while completing the
electrical connections to the burner.

ELECTRODE SETTING
OIL LINE CONNECTIONS
Note: Pump pressure must be set at time of burner start-up. A pressure gauge
is attached to the PRESSURE PORT (8) for pressure readings. Two PIPE
CONNECTORS (5) are supplied with the burner for connection to either a single
or a two-pipe system. Also supplied are two ADAPTORS (3), two female 1/4”
NPT, to adapt oil lines to burner pipe connectors. All pump port threads are
British Parallel Thread design. Direct connection of NPT threads to the pump will
damage the pump body. Riello manometers and vacuum gauges do not require
any adaptors, and can be safely connected to the pump ports. An NPT (metric)
adapter must be used when connecting other gauge models.
