Installation guide

For oil fired boilers for connections to vents or chimneys,
vent installations shall be in accordance with applicable
provisions of INSTALLATION OF OIL BURNING EQUIPMENT,
NFPA31 latest revision, and applicable provisions of local
building codes.
Fresh air (ventilation) is important to proper
venting. Ventilation and venting are two parts of the
same system. Inadequate ventilation will result in
inadequate venting. Always be sure to have enough
ventilation to support proper venting.
Check your chimney to make certain that it is right size,
properly constructed and in good condition.
See Table "Recommended Minimum Chimney Sizes".
For additional chimney design and sizing information,
consult the National Standard for Chimneys, Fireplaces,
Vents and Solid Fuel Burning Appliances, ANSI/NFPA 211.
Fire Hazard. Maintain minimum vent pipe clearance
of 18" from surface of vent to wood and other
combustible materials. Failure to comply may result
in death or serious injury.
Chimney Connector And Draft Regulator
• Venting the boiler requires 6" diameter chimney
connector pipe and use of manufacturer provided draft
regulator.
• Regulator, when properly installed, automatically
controls the draft.
• Install in horizontal section of pipe, may also be
installed in angled or vertical section of pipe.
• Verify "top" of regulator is at the top and short pipe
section which holds the vane is horizontal.
• Even though locating draft regulator close to chimney
reduces noise, install draft regulator as close as
practicable to the boiler,
• Install chimney connector, start at boiler with vertical
pipe, elbow, then install draft regulator horizontally.
• When regulator is in place, start at chimney and work
back to the regulator.
• Join the two sections with draw-band.
• Horizontal pipe must slope up toward the chimney at
least 1/4, inch per linear foot of venting.
• Chimney connector must not leak and must be firmly
supported.
• Join each section with at least two sheet metal screws.
Support every second section with a stovepipe wire.
