Stove Installation - Lennox Hearth Products ST310 Installation And Operation Manual

STOVE INSTALLATION

1. If not previously installed, install floor protection and move the
heater into the desired location.
2. Position the stove on your floor protection in the exact location
where it is to be located, making sure all minimum clearances are
met.
3. If you are installing outside air on your stove, mark a 4" circle on
the floor protection just below the oblong ring. When cut out,
this hole will accommodate the flexible outside air tube.
4. If the stove is to be fastened to the floor, locate the hold down
brackets inside the leg box and mark the floor protection below
the holes in the brackets.
5. If you are installing outside air on your stove, remove the stove
and cut the floor protection and the floor where the 4" air tube
circle had been previously drawn. If the stove is to be fastened to
the floor, drill 1/2" holes through the floor protection only, at the
marks that were for fastening the stove to the floor if so desired.
Slip the flexible outside air tube through the hole in the floor,
leaving 1" of tube above the floor protector surface, using tape to
hold it in place.
6. Place the stove on the floor protection so that the previously cut
or drilled holes line up. Attach the stove to the floor with the lag
bolts if so desired.
7. If you are installing outside air on your stove place the hose
clamp over the flexible air tube and slide the tube up over the 4"
ring on the outside air adaptor box and tighten the hose clamp.
Push the outside air adaptor forward 1/4" until full contact is
made with the lower heatshield. Tighten the 1/4" bolt until the
adaptor box is held firmly in place. Use silicone sealant to create a
seal between the flexible air tube and your floor protection.
8. If it is necessary to level, secure, or ground your stove, use the
holes in the bottom of the leg for those applications. To level the
stove on Olympic cast legs, locate the front leg that is not touch-
ing the hearth pad. Insert the allen head screw through the slotted
washer (supplied with the legs) and into the threaded hole in the
bottom of the leg. See the drawing to the right. Push the slotted
washer down until it touches the hearth pad and then tighten the
screw into the leg. Should any other leg not be resting on the
hearth pad, install a washer and screw in that leg as well.
9. Install bricks and baffle as per instructions on Pages 14 and 15.
It is highly recommended that the baffle be assembled before the
chimney is installed so that the baffle blankets can be adjusted
into place through the flue collar.

10. If installed into a mobile home, the stove shall be grounded to the
mobile home chassis with a #8 AGW copper wire or equivalent.
11. For residential installations, install the first section of stove pipe
with the crimped end going down inside the flue collar on the heater.
Continue with your stove pipe, installing each section-crimped end
down. Make the final connection to your chimney. Your dealer car-
ries the necessary pipe and fittings to connect to the various listed
factory-built chimneys. YOUR CHIMNEY INSTALLATION MUST
COMPLY WITH LOCAL BUILDING AND FIRE CODES.
12. Be sure to fasten each stove pipe connection with at least 3 sheet
metal screws.
13. Install chimney as per manufacturer's instructions. Some brands of
pipe may require removal of the spacer ring in the flue collar.
14. All horizontal runs of pipe should be as short as possible and are
required by NFPA No. 211 to have an upward pitch or rise in the same
direction the smoke travels of no less than 1/4" to the linear foot.
The connector pipe must meet minimum clearances in any direction
to walls or other combustible materials. It must attach to a listed
double wall metal chimney at least 6" in diameter or to a masonry
chimney with a flue passage of at least 48 square inches.
15. It is required that a chimney connector pipe not extend further than
the inner wall of the flue when it is connected to a masonry chimney
and that it either be cemented to the masonry or be installed without
cement in a thimble connected to the masonry wall. When the con-
nector is inserted into a thimble, the joint must be tight enough so
that it will not be dislodged in normal use. Install connector at no
less than the minimum clearances from the ceiling when using a
90-degree elbow to pass through combustible constructions.
16. Chimney connector pipes should never pass through a floor, ceiling,
fire wall, partition, or combustible construction of any type unless
certain precautions are taken. The best method is to use a listed thimble
and a listed chimney in accordance with the manufactures directions.
NFPA No. 211 gives approved methods for passing a flue pipe through
combustible constructions.
