“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
flue lined masonry chimneys meet venting
requirements.
• External chimneys are more susceptible
to flue gas condensation due to colder
outside air temperatures. To prevent
corrosion due to flue gas condensation,
use a listed corrosion-resistant metal
liner in chimney.
• Oversized chimneys are more
susceptible to flue gas condensation.
To reduce the likelihood of flue 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 qualified 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 qualified person in
accordance with the requirements of Chapter
11 of NFPA 211, Standard for Chimneys,
Fireplaces, Vents, and Solid Fuel-Burning
Appliances.
a. Loose Mortar – Loose mortar could be an
indication of a prior history of condensing
flue gases upon the inside walls of the
chimney. Colder climates are more
susceptible to this condition. Under
no circumstances shall a chimney of
this condition be used until it meets the
requirements of NFPA 211 or CSA B139.
b. Unlined Chimney – Under no circumstances
shall a chimney constructed of brick only be

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.
Insufficient 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 flue 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 fire 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.
