General chimney requirements
•
Designed for natural draft firing. Connect boiler
to vertical chimney.
Insufficient draft can cause flue gas leak-
age and carbon monoxide emissions,
which will lead to severe personal injury
or death.
•
Use vent material approved by local codes for oil-
fired burners. In their absence, refer to:
•
NFPA 31, Installation of Oil-Burning Equip-
ment.
•
NFPA 211, Standard for Chimneys, Fireplaces,
Vents and Solid Fuel Burning Appliances.
•
In Canada, refer to CSA B139, Installation Code
for Oil-Burning Equipment.
•
NFPA 211 requires chimney to be lined before con-
nected to boiler.
Inspect existing chimney before installing new boiler. Failure
to do any of the following will result in severe personal injury
or death:
•
Clean chimney, including removal of blockage.
•
Repair or replace damaged pipe or liner.
•
Repair mortar and joints.
To prevent downdrafts, extend chimney at least 3 feet above highest point
where it passes through roof and 2 feet higher than any portion of building
within 10 feet. Increase chimney cross-sectional area and height at least
4% per 1,000 feet above sea level.
•
Minimum clearances from vent pipe to combustible material:
•
6 inches — Type “L” double-wall vent
•
9 inches — Single-wall vent
•
Minimum chimney sizes should be used.
Oversized chimneys, outside masonry chimneys and/or der-
ated inputs can result in condensation in chimney.
