The Field Direct Vent System (FDVS) is a non-powered positive pressure side wall vent termination system for use only with
specifically listed oil fired appliances. The system provides an outlet for exhaust gases and an intake for combustion air in a single concentric terminal. The FDVS termination is designed to direct the hot exhaust gases away from the structure using the static pressure generated by a special oil burner. All of the internal parts in contact with the flue gases are made from corrosion resistant 316L stainless
steel. The FDVS, with its built-in combustion air tee, allows connecting standard galvanized pipe from the FDVS termination to the air
intake of a special oil burner or by use of a Field Controls Airboot, depending on the model of the oil burner.

i
apply the supplied
high temperature
sealant to the cover
pan around the
inner pipe, around
the joint between
the collar and the Tee assembly, and seal or
tape the joint from the FDVS Termination to the Tee assembly.
NOTE: The tee may be rotated into any position so that the collar
is in a convenient orientation.
CLEARANCE TO COMBUSTIBLES: FDVS Termination: 0",
FOVP Flexible Oil Vent Pipe: 1". These clearances are to maintained unless superceded by National and/or local codes
(see Step 3).
CONNECTING THE VENT PIPE FROM THE FDVS
TO THE APPLIANCE
1. The venting system should be installed and supported in
accordance with the latest version in the USA of the National
Fuel Gas Code ANSI Z223.1, UL-726, National Fire
Protection Association NFPA31, and in Canada CSA B140,
CSA B139 Installation Code or in accordance with any other
local codes or the authority having jurisdiction. Where
requirements for venting differ the most stringent standard
requirements shall apply. A vent pipe connector, designed for
positive pressure venting, shall be supported for the design
and weight of the material employed, to maintain clearances,
prevent physical damage and separation of joints. All joints
MUST be sealed, for positive vent pressure, to prevent flue
gas leakage into the structure.
2. Route the vent pipe from the appliance to the vent termination
using the minimum number of bends as possible. The last
horizontal section of the vent pipe should have a slight downward slope from the appliance to the vent termination. For
clearances to combustible materials and other installation
requirements, refer to the National Fuel Gas Code ANSI
Z223.1, UL-726, NFPA31, CSA B140, CSA B139 and/or any
applicable local codes.
3. The maximum length of vent pipe run for the EC-10DV boiler
series is 15 feet. The minimum diameter of the approved vent
pipe is 4" for the EC-10DV boiler series. Use a reducer or
increaser, if necessary, at the vent termination to connect the
vent pipe.
4. Support the Flexible Oil Vent Pipe (FOVP) at regular intervals
of maximum 36" spacing with appropriate strapping or hangers, per National and local code requirements. Do not install
screws into or otherwise penetrate any part of the vent pipe
under any circumstances.
Figure 18 - Top View
CONNECTING THE COMBUSTION AIR INTAKE PIPE FROM
THE FDVS TO THE APPLIANCE
1. Use 4" galvanized steel pipe or stainless steel pipe from the
DVS terminal combustion air tee collar to the appliance oil
F
burner combustion air inlet (or Air boot, if applicable.) Use a
reducer or increaser, if necessary at the burner combustion air
inlet to connect the combustion air intake pipe.
. The VRV should be installed close to the air inlet of the
2
burner, see fig. 14 on page 8.
GENERAL INSTALLATION INSPECTION
ecommended procedures for safety inspection of an appliance
R
should be in accordance with the latest version of the National
Fuel Gas Code ANSI Z 223.1, UL 726, and the National Fire
Protection Association NFPA 31 in the USA, CSA B140 and CSA
B139 Installation Code in Canada. The following procedure will
help evaluate the venting system. It is intended as a guide to aid
in determining that the venting system is properly installed and is
in a safe condition for continuous use. This procedure should be
recognized as a generalized procedure which cannot anticipate
all situations. Accordingly, in some cases, deviation from this procedure may be necessary to determine safe operation of the
equipment. If it is determined that a condition exists which could
result in unsafe operation, the appliance should be shut off and
the owner advised of the unsafe condition. Corrections must be
made before the appliance is put into continuous operation. The
following steps should be followed in making a safety inspection.
1. Visually inspect the venting system for proper size and deter
mine that there is no flue gas spillage, blockage, restriction,
leakage, corrosion, or other deficiency which could cause an
unsafe operation.
2. Place in operation the appliance being inspected. Follow the
lighting instructions and adjust thermostat so appliance will
operate continuously.
3. Determine that the burner is operating properly and that the
burner ignition operates satisfactorily by interrupting and
reestablishing the electrical power of the appliance in any
convenient manner. Test the burner safety device to determine
if it is operating properly by disconnecting the flame
safety circuit.
4. Test for spillage at the burner inlet air location around the VRV
after 5 minutes of operation. Use a draft gauge, flame of a
match or candle, or smoke from a cigarette, cigar or pipe.
Shut off appliance thermostat and check for spillage around
the VRV. If a flow reversal is noticed, house depressurization
is occurring and make up air is required.
MAINTENANCE
Inspect all vent connections annually for looseness, evidence of
corrosion, or flue gas leakage. Replace, seal, or tighten pipe
connections if necessary. As part of the yearly maintenance
schedule, remove the Intake Access Panel on the exterior of the
FDVS vent termination (See Figure 17) and remove any debris or
foreign material. Be sure to properly replace the panel.
