Freestanding Installations - The stove must be placed on a continuous
(grouted joints) noncombustible material such as ceramic tile,
cement board, brick, 3/8” (10 mm) millboard or equivalent, or other
approved or listed material suited for floor protection.
THE MATERIAL(S) USED MUST HAVE, OR COMBINE TO HAVE, A
MINIMUM INSULATIVE RATING OF ‘R1’.
NOTE: ceramic tile, or any tile, requires a continuous sheet beneath
to prevent the possibility of embers falling through to the combustible
floor if cracks or separation should occur in the finished surface,
this would include floor protection for Built-in raised hearths. Check
local codes for approved alternatives. Clearances are measured from
the sides, back and face (door opening) or stove body. DO NOT USE
MAKESHIFT MATERIALS OR COMPROMISES IN THE INSTALLATION
OF THIS UNIT. INSTALL VENT WITH CLEARANCES SPECIFIED BY
THE VENT MANUFACTURER. CAUTION: DO NOT CONNECT TO OR
USE IN CONJUNCTION WITH ANY AIR DISTRIBUTION DUCTWORK
UNLESS SPECIFICALLY APPROVED FOR SUCH INSTALLATIONS.
COMBUSTION AIR SUPPLY
If outdoor combustion air is supplied the heater must be attached
to the structure. For a mobile home installation the stove must be
connected to an outside source of combustion air. A 2” (51 mm) inside
diameter metallic pipe, either flexible or rigid, may be attached to
the inlet at the stove’s rear as shown. A rodent guard (minimum
1/4” (7 mm) wire mesh)/wind hood must be used at the terminus.
All connections must be secured and airtight by either using the
appropriately sized hose clamp and/or UL-181-AP foil tape. For
mobile home installations only: 2” (51 mm) inside diameter pipe
may be used for the first 5 feet (1.5 m) of combustion air supply run.
From 5 to 10 feet (1.5 m to 3 m) use 2-3/4” (61 mm) inside diameter
pipe. No combustion air supply may exceed 10 feet (3 m).
Sources of Outside Combustion Air
a. In fireplaces
• Chimney top.
• Ash clean out door.
b. For freestanding installations
• A hole in the floor near stove rear terminating only in a
ventilated crawl space.
• A hole in the wall behind the stove.
WHEN OUTSIDE AIR IS NOT USED
If outside air is not used, it is important that combustion air is easily
available to the air inlet. A closable outside air register can be used
in tightly insulated homes.
IMPORTANCE OF PROPER DRAFT
Draft is the force which moves air from the appliance up through
the chimney. The amount of draft in your chimney depends on the
length of the chimney, local geography, nearby obstructions and
other factors. Too much draft may cause excessive temperatures
in the appliance. Inadequate draft may cause backpuffing into the
room and ‘plugging’ of the chimney. Inadequate draft will cause
the appliance to leak smoke into the room through appliance and
chimney connector joints. An uncontrollable burn or excessive
temperature indicates excessive draft. Take into account the
chimney’s location to ensure it is not too close to neighbors or in a
valley which may cause unhealthy or nuisance conditions.
VENTING
This freestanding unit is certified for use with listed TYPE PL-Vent, 3”
or 4” (77 mm or 102 mm) diameter in size. The stove was tested with
Simpson Duravent brand. Class “A” chimney is not required. Refer
to the instructions provided by the vent manufacturer, especially
when passing through a wall, ceiling or roof. This is a pressurized
exhaust system. All vent connector joints must be sealed with 500°F
(260°C) RTV silicone sealant to ensure consistent performance
and avoid smoke spillage. All horizontal connector joints must be
sealed with UL-181-AP foil tape. We recommend that all vertical
vent connector joints be secured with a minimum of 3 screws. It
is strongly recommended that you have a minimum of 6 feet (1.8
m) of vertical pipe in your exhaust system. For best performance
of the stove limit the number of elbows and horizontal pipe as
much as possible. A chimney connector shall not pass thorough 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 shall conform to CAN/
CSA-B365, installation code for solid-Fuel-Burning appliances and
equipment.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING
ANOTHER APPLIANCE. DO NOT INSTALL A FLUE DAMPER IN
THE EXHAUST VENTING SYSTEM OF THIS UNIT. INSTALL VENT AT
CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.
EQUIVALENT VENT LENGTH (EVL)
The longer the run of pipe in your installation (both with inserts and
freestanding), the more restriction there is in the system. Therefore,
larger diameter pipe should be used.
• Use 4” (102 mm) pipe if you have more than 15 feet (4.6 m) of
equivalent vent length.
• Horizontal runs shall not exceed 10 feet (3 m) of EVL.
• It is recommended that vertical runs be a minimum of 8 feet.
• To calculate EVL, use the following conversions:
90º elbow or “T”
= 5 equivalent feet
45º elbow
= 3 equivalent feet
Horizontal Pipe Run
= 1 equivalent foot per actual foot
Vertical Pipe Run
= 0.5 equivalent foot per actual foot
NOTE: At altitudes above 3,000 feet (914.4 m), we suggest the use of
4” (102 mm) diameter vent at an EVL of 7 feet (2.1 m) or more.
