Installation & Service Manual
A. CHIMNEY VENTING
1. Chimney venting is an important part of a safe
and efficient oil fired appliance system. Contact
your local fire and building officials on specific
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 fired boilers is dependant
on many factors. Some of these factors include:
a. sufficient 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 flue gases. Only a trained and
qualified contractor may install this product.
3. The MegaSteam 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
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 used. Only approved clay liners or listed
chimney lining systems shall be used as
specified in NFPA 31 or CSA B139.

Venting & Air Intake Piping
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.
