Lennox Hearth STRIKER SWS160 - Manual (Page 12)

12 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
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
connector 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.
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 touching 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 Figure 12. 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 baffle boards and baffle blanket 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 blanket 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
carries 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.
