There are two types of chimney connectors :
A single wall chimney connector may be used for top
connection :
This connector must be 316 grade 26 gauge stainless steel or 1 mm
vitreous enamelled steel and with a 5" (127 mm) diameter. Secure
the connector joints with 3 sheet metal screws. The joints are to be
airtight. All connector sections must be attached to the unit and to
each other with the crimped or male end pointing down towards the
oil stove.
Use a double wall chimney connector for rear connec-
tion :
The connector should be of the same make (manufacturer) as the
chimney components.
Chimney installation
Connection to a A-VENT chimney :
An A-Vent chimney, either 4" (101,6 mm.) or 5" (127 mm.) in diameter may be used.
The minimum chimney height is to be 15 feet or 4.6 metres measured from the
appliance flue collar to the top of the chimney but not including any chimney caps.
Installation of all chimney systems is to be in accordance with the chimney
manufacturers installation instructions. If the stove is to be connected to a masonry
chimney, a stainless steel liner is required. DO NOT USE ANY MAKESHIFT
MATERIALS DURING INSTALLATION.
1. Move the stove into position with the flue centred, mid point between two joists to
prevent having to cut them. Use a plumb bob to line up the centre.
2. Cut and frame an opening in the roof to provide a 2" (50 mm) clearance between the outside of the chimney and any
combustible material. DO NOT FILL THIS SPACE WITH ANY TYPE OF MATERIAL.
Nail headers between the joists for extra support. Firestop spacers must be placed on the bottom of each framed opening
in any floor or ceiling that the chimney passes through (figure 5).
3. Hold a plumb bob from the underside of the roof to determine where the opening in the roof should be. Cut and frame
the roof opening to maintain proper 2" (50 mm) clearances (figure 6).
Example : A = Chimney di 2 times the required clearance from chimney to combustible framing materials.
Connection to a L-VENT chimney :
This appliance is certified to be connected to a L-VENT chimney, 5" (127 mm). Use NAPOLEON ADAPTOR, W 175-0198.
This adaptor is specifically designed for Energy Vent Chimney.
Adding chimney sections
Add chimney sections, twist locking (clockwise) securely, to the required height. Safety requirements dictate that the
chimney must be at least 3 feet (915 mm) higher than the highest point where it passes through the roof and at least 2 feet
(610 mm) higher than the highest part of the roof or structure that is within 10 feet (3.05 m) of the chimney, measured
horizontally (figure 7). Obstacles close to the chimney may cause down drafts which may be prevented by the installation
of a chimney cap fitted with a wind deflector. If your chimney system is enclosed within the attic area, a rafter radiation
shield is required.
MOBILE HOME INSTALLATION
In mobile home installation, the oil stove must be installed with an oil drip tray. Order this part, 72636, from your Napoleon
dealer
When installing the OS11 into a mobile Home, a carburetor support (supplied) must be installed for extra support of the
carburetor (fig. 4). Ensure the support is adjusted to make contact with the floor. Outside air intake is mandatory in mobile
homes only.
