H. CHIMNEY VENTING
1. Chimney venting is an important part of a safe
and efcient oil red appliance system. Contact
your local re and building ofcials on specic
requirements for restrictions and the installation of
fuel oil burning equipment. In addition, consult with
a professional knowledgeable on the requirements of
NFPA 31 – Standard for the Installation of Oil-Burning
Equipment and NFPA 211 - Standard for Chimneys,
Fireplaces, Vents, and Solid Fuel-Burning Appliances
for installations in the United States. Installations
in Canada must be reviewed with a professional
knowledgeable on the requirements of CSA B139 –
Installation Code for Oil-burning Equipment.
2. The safe venting of oil red boilers is dependant on
many factors. Some of these factors include:
a. sufcient draft during the entire heating season
to allow for the safe discharge of combustion by-
products and;
b. suitable corrosion protection in the event of
condensing ue gases. Only a trained and qualied
contractor may install this product.
3. The RRO shall be vented into any of the following:
a. Masonry or metal chimney. Build and install in
accordance with local buildings codes; or local
authority having jurisdiction; or “Standards
for Chimney, Fireplace, Vents, and Solid Fuel
Burning Appliances”, ANSI/NFPA 211 and/or
National Building Code of Canada. Masonry
chimney must be lined with listed chimney
system. Listed clay ue lined masonry chimneys
meet venting requirements.
• External chimneys are more susceptible to
ue gas condensation due to colder outside
air temperatures. To prevent corrosion
due to ue gas condensation, use a listed
corrosion-resistant metal liner in chimney.
• Oversized chimneys are more susceptible
to ue gas condensation. To reduce the
likelihood of ue gas condensation and
ensure proper draft, use a properly sized
listed metal liner in oversized chimney.
4. Chimney Inspection – Prior to the installation of
any new or replacement fuel burning equipment the
chimney shall be inspected by a qualied installer.
The chimney shall be inspected for integrity as
well as for proper draft and condensate control.
Some jurisdictions require the use of a liner when
changing fuel types. Some jurisdictions require
the use of a liner even when the same fuel is used.
At a minimum, the chimney shall be examined
by a qualied person in accordance with the
requirements of Chapter 11 of NFPA 211, Standard
for Chimneys, Fireplaces, Vents, and Solid Fuel-
Burning Appliances.

WARNING
Vent this boiler according to these instructions. Failure to do so may cause products of combustion to
enter the home resulting in severe property damage, personal injury or death.
Insufcient Combustion Air Supply may result in the production and release of deadly carbon
monoxide (CO) into the home which can cause severe personal injury or death.
Improper venting may result in property damage and the release of ue gases which contain deadly
carbon monoxide (CO) into the home, which can cause severe personal injury, death, or substantial
property damage.
Inspect existing chimney and vent connector for obstructions and deterioration before installing
boiler. Failure to clean or replace perforated pipe or chimney liner will cause severe injury or death.
Do not de-rate the appliance. Failure to re the boiler at it's designed input may cause excessive
condensation upon the interior walls of the chimney. In addition, the lower input may not create
enough draft to adequately evacuate the by-products of combustion.
