INSTALLATION OF THE VENT TERMINATION

COMBUSTION AIR TEE
1. Assemble the combustion air tee assembly body to the vent

termination outer pipe, and rotate to the desired position.

Attach the tee assembly body to the vent termination outer

pipe with at least 3 sheet metal screws evenly spaced apart

(not included).

2. After completing

assembly of the

vent pipe to the

termination

inner pipe (Fig. 19),

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 main-

tained unless superceded by National and/or local codes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 down-

ward 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 hang-

ers, per National and local code requirements. Do not install

screws into or otherwise penetrate any part of the vent pipe

under any circumstances.

CONNECTING THE COMBUSTION AIR INTAKE PIPE FROM

THE FDVS TO THE APPLIANCE
1. Use 4" galvanized steel pipe or stainless steel pipe from the

FDVS terminal combustion air tee collar to the appliance oil

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.

2. The VRV should be installed close to the air inlet of the

burner, see fig. 14 on page 8.

GENERAL INSTALLATION INSPECTION
Recommended procedures for safety inspection of an appliance

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 pro-

cedure 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.
