2. Burn wood or wood products only. Th e wood should be air dried for at least
six months prior to use for maximum effi ciency.
3. Aft er the fi re has been started and is burning satisfactorily, adjust the rate of
burning by opening or closing the damper in the fl ue collar.
4. Never build extremely large fi res in this type of heater as damage to the heater
or smoking may result.
5. Provide air into the room for combustion.
6. Do Not touch the heater aft er fi ring until it has cooled.
7. Do Not use a grate or elevate fi re, build fi re directly on hearth.
8. Th e fuel feed door must remain closed during operation.

Chimney Connection
MASONRY CHIMNEY
Th e masonry chimney must comply with UL codes. Before using an existing
masonry chimney, clean the chimney and inspect the fl ue liner to be sure it is safe
to use. Make repairs before attaching the heater. See Page 3, Item 5. Look at Fig.
5. Th
e connector pipe and fi ttings you will need to connect directly to a masonry
chimney are shown. If the connector pipe must go through a combustible wall
before entering the masonry chimney, consult a qualifi ed mason or chimney
dealer. Th
e installation must conform to local fi re codes and NFPA 211. Do not
connect this heater into the same chimney fl ue as the fi replace or fl ue from another
heater. Th
e chimney used for a heater must not be used to ventilate the cellar or
basement. If there is a cleanout opening at the base of the chimney, close it tightly.
UL/ULC LISTED CHIMNEY
Carefully follow chimney manufacturer's instructions. Use only listed type HT per UL
103, 6-in diameter black or blued chimney connector, minimum 24 gauge steel. If your
chimney starts at the ceiling (Fig. 6), you will need enough 6" pipe to reach the ceiling.
Th e top of the chimney must be at least 3 feet above the roof and be at least 2 feet
higher than any point of the roof within 10 feet. (Fig 6). Use double or tripple wall
pipe for the exterior portion of the chimney.
RULES FOR CONNECTOR PIPE INSTALLATION
1. Crimped end of the pipe must be installed toward the heater. Th e pipe should
slide into the fl ue collar. Th e pipe should be fi rmly attached to the fl ue collar
with 3 screws and sealed with furnace cement.
2. Slope any horizontal pipe upward toward the chimney at least 1/4 inch for
each foot of horizontal run. Horizontal section must be a minimum of 24"
from stove.
3. You must have at least 18" inches clearance between any horizontal piping and
the ceiling.
4. Th e pipe cannot extend into the chimney fl ue.(Fig. 7)
5. Seal each connector pipe joint with furnace cement. Also, seal the pipe at the
chimney. Seal the inside with high temperature silicone and the outside with
high temperature tape.
6. Use 3 sheet metal screws at each joint to make the piping rigid.
7. It is recommended that no more than two (2) 90 degree bends be used in the
stove pipe installation as more than two (2) may decrease the amount of draw
and possibly cause smoke spillage.
NOTE: Th e chimney connector shall not pass through an attic, roof space,
fl oor, ceiling, or similar concealed space. Where passage through a wall
or partition of combustible construction is desired, the installation must
conform with NFPA 211.
