Ducting Outside Combustion Air; Possible Flue Or Chimney Defects; Fuel; Loading Of Fuel - Newmac NS220 Installation, Operating And Service Manual

DUCTING OUTSIDE COMBUSTION AIR

Indirect method – NS220 (Newmac Status) and NC100 (Newmac Classic): outside air may be ducted to a point no
closer than 300 mm (12 in) from the heater, to avoid affecting the heater's performance.
Direct connection – NCM120 (Newmac Classic II, Mobile): This heater is approved for direct connection of outside air as
described on page 12.

POSSIBLE FLUE OR CHIMNEY DEFECTS

From the foregoing basic principles for the regulation of chimney flues, it will be seen that unsatisfactory stove operation
may be the result of any of the following possible chimney flue defects:
1. Insufficient height.
2. Surrounding nearby objects throwing air currents down the chimney.
3. Flues enlarged or contracted at some point.
4. Rubbish or soot obstruction in the flue.
5. Air leakage in cracks where mortar has fallen out.
6. Floor support or a pipe passing through or entering the flue.
7. Too abrupt offsets.
8. Other connecting flues
9. Chimney being used for ventilating basement
10. Chimneys too large for stove being used.
11. Flues being long and narrow
12. More than one smoke-pipe connected to the flue.
13. Chimney connector protruding too far into the chimney.

FUEL

Mixed dry hard wood will give the most heat. Your heater will handle most any type of wood, but some types produce
more heat than others and will hold fire longer. Coal should never be used in a heater designed for burning wood.
Never use driftwood that has been in salt water for a long period. The salt content may cause excessive corrosion and
shorten the life of the firebox.
Hard wood cut to 20" maximum length, and split 3" to 6" cross section is recommended for best operating efficiency.
CAUTION: Burn untreated wood only. Wood containing preservative, metal foils, coal, plastic, garbage, sulfur or oil
may be hazardous and damage the appliance.

LOADING OF FUEL

Do not overfill the firebox above the firebrick. Wood should be 3 to 4" below top of firebrick. A burned-out heat chamber
may result. Do not use artificial logs.
Build fire on the floor of the NS220 (Newmac Status) and on the built-in grates of the NC100 (Newmac Classic) and the
NCM120 (Newmac Classic II, Mobile) heaters. Do not use additional grates or andirons to support the fire as these may
create excessive heat.
For the most heat, combustion air must be able to circulate around and through the fire. Do not block the air entrances
inside the firebox with ashes.
PREPARATION AND STORAGE OF FUEL
Solid fuel should be cut and split prior to the heating season and stored in a well aired, dry place. Do not store fuel
within the room heater clearances or within the space required for fuelling or ash removal. Fuel should be kept at least
5ft clear (1.5m) from the heater. The space around the heater should be kept free of litter and wood residue.
LIGHTING and OPERATION
1. Set thermostat on HIGH to provide maximum draft.
2. Open loading door and lay fire, using ample kindling to ensure rapid ignition.
3. Prime chimney - hold lighted newspaper up towards flue baffle.
4. Light fire and close loading door.
5. Wait 3 - 5 minutes then add dry logs. (See section concerning Flue).
