2. Hazardous carbon dioxide or carbon monoxide gas may be produced by improper installation, operation, fuelling or
maintenance of this appliance.
3. As required by the installation codes, provide air for combustion from the outside into the room where the heater is
located. For models NS220 (Newmac Status) and NC100 (Newmac Classic), if the intake is not in the same room,
the air must have free access to the room. Install air duct for NCM120 (Newmac Classic II Mobile) as specified.
4. Do not use substitute materials or unspecified components. Suitable original-equipment replacement-parts are
available from Newmac Mfg.
5. Do not use abrasive cleaners.
6. Do not clean when hot.
NOTE: The special paint used on your heater may give off some odor while it is curing during the first few fires. Build small fires at first.
CHIMNEY CONNECTOR (STOVE OR FLUE PIPE)
Newmac wood fired heaters require 6” (150mm) diameter mild steel chimney connectors of at least 24ga (0.53mm or
0.0206ins) metal thickness, or equivalent. (Galvanized steel is not acceptable). Secure each chimney connector joint
with three sheet metal screws and connections to the appliance with a minimum of 2 sheet metal screws. For better
performance, seal each connector joint with a small quantity of furnace cement. Ensure that the vent system can be
taken apart for periodic inspection and cleaning.
Chimney connector must not pass through an attic or roof space, closet, or similar concealed space or a floor or ceiling.
Where passage through a wall or partition of combustible construction is desired, the installation must conform to NFPA
211 (USA) or CAN/CSA B365 (Canada) requirements.
The crimped end of the chimney connector fits inside the heater flue collar. Additional pipe and elbow should be
installed with CRIMPED END TOWARD THE HEATER. This will let condensation in the flue to run back into the heater.
Chimney connectors for the NCM120 Newmac Classic II Mobile home heater must be sealed with furnace cement.
REDUCING EXCESSIVE DRAFT
Where permitted by the regulatory authority a hand operated flue pipe key-damper may be installed.
CONNECTION TO A MASONRY CHIMNEY THROUGH A COMBUSTIBLE WALL
The heater may be connected to a masonry chimney, which conforms to the installation code requirements. Various
methods of connection are shown in these installation codes. Check with your local regulatory authority as to which
methods they will accept. Care must be taken when the chimney connector passes through a combustible wall to
ensure that there is sufficient clearance from the chimney connector to the combustible wall material.
