A. 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 MPO-IQ 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.
V. NATURAL DRAFT VENTING (All Boiler Models)
• 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.
a. Loose Mortar – Loose mortar could be an indication
of a prior history of condensing ue 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 specied in NFPA 31 or CSA B139.
c. Abandoned Openings – Openings through the
chimney wall that are no longer used shall be sealed in
accordance to NFPA 211. Often abandoned openings
are improperly sealed and usually covered by a gypsum
wall covering.
d. Clean Chimney – Chimney shall be free of all loose
debris.
5. Draft Regulator – the draft regulator supplied with the
boiler (or equivalent) must be used with this appliance.
Refer to Figures 15 and 16.
WARNING
Vent this boiler according to these supplemental 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.
