Venting

SECTION VI - Venting

Oil Vent - General Requirements

Improper installation of vent system

could cause improper draft causing flue

gas leakage and carbon monoxide emis-

sions, which could cause severe personal

injury or death.

Installation must comply with local require-

ments for oil burning appliances. In absence of

local codes the installer should refer to:

• NFPA 31, Installation of Oil-Burning

Equipment

• NFPA 211, Standard for Chimneys,

Fireplaces, Vents and Solid Fuel

Burning Appliances.

• In Canada, the installer should refer to

CSA B139, Installation Code for Oil-

Burning Equipment.

NFPA 211 requires the chimney to be lined

before connecting to the ELITE appliance.

Inspect existing chimney before

installing the ELITE. Failure to com-

plete the following guidelines will result

in severe personal injury or death:

- Clean the chimney, including

removal of any blockages

- Repair or replace any deteriorating

or damaged vent pipe or liner

- Repair any damaged chimney mor-

tar or joints

The chimney must extend a minimum 3 feet

above the highest point where it passes through

the roof and 2 feet higher than any portion of

the building within 10 feet.

The cross sectional area of the chimney and the

height must be increased at minimum 4% per

1,000 feet of elevation above sea level.

The installer must maintain minimal clearances

from the vent pipe to combustible material as

follows:

-Type “L” doublewall vent - 6 inches

- Single wall vent pipe - 18 inches

The chimney size should be maintained as min-

imal, oversize chimneys could result in the for-

mation of condensate in the chimney.

Oil Vent Piping

Long horizontal vent runs, excessive

number of tees or elbows or other fittings

that restrict the combustion flue gas flow

can result in potential flue condensation,

flue gas leakage and/or carbon monoxide

emissions, which can lead to severe per-

sonal injury or death.

When the burner and the ELITE are properly

installed, the overfire draft on the ELITE should

be approximately (-)0.01”w.c to (-)0.02”w.c.
