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.
