3.D Vertical Venting - Category I
All venting must comply with fuel gas code and be
installed by a licensed installer.
This boiler can be vented into a masonry chimney,
(see Figure 7 and Figure 8 on page 12) provided
several conditions are met:
1. The chimney must have an appropriate lining that
is clean, properly constructed and properly sized.
2. The chimney passage way shall be examined to
ascertain that it is clear and free of obstructions.
3. If a chimney rebuild is required, it shall conform
to nationally recognized standards (see National
Building Code or ANSI/NFPA 211).
4. The boiler must not be connected to a fireplace,
wood stove or other solid fuel burning equipment.
5. When the boiler and a hot water heater are to be
connected to the same chimney, they must have
their own vent connector and enter the chimney at
least 6” (152mm) apart.
IMPORTANT NOTE: Always provide a minimum
clearance of 6” (152mm) between Type C (single
wall) vent pipe and any combustible materials.
NOTE: Exterior masonry chimneys in very cold
environments are at risk of condensing due to the
high efficiency of this equipment. Insulated liners
are recommended based on local conditions and
expected system water temperatures. Also ensure
the boiler’s anti-condensing features are utilized by
properly wiring the system pumps. See Figure 28 on
page 27
WARNING
Do not store any chemical, cleaners, or other
corrosive material near combustion air openings
or in the room. Avoid locating dryer vents in the
vicinity of combustion air openings. Failure to
prevent corrosive materials from mixing with
combustion air can result in reduced boiler life
and unsafe boiler operation.
AVERTISSEMENT
N’entrepposer aucun produit chimique, produit
nettoyant ou produit corrosif à proximité des
bouches d’air de combustion ou dans la pièce.
Éviter de placer des tuyaux de ventilation pour
sécheuse à proximité des bouches d’air de
combustion. Le fait de laisser des maitières
corrosives se mélanger à l’air de combustion
risque de réduire le cycle de vie de l’appareil
de chauffage et de compromettre son
fonctionnement.
WARNING
Single wall vent pipe must NEVER pass through
interior walls or through floors or ceilings! Failure
to comply with this warning could result in a fire
causing property damage, personal injury, or death!
