EQUIvALENT vENT LENgTH
The longer the run of pipe in your installation, the more restriction there is in the
system. Therefore larger diameter pipe should be used for longer runs.
Use 76.2 mm (3 in) pipe if you have less than 4.57 m (15 ft) of equivalent vent length
(EVL).
To calculate EVL, use the following conversion table:
Qty
Type of pipe
1
90 degree elbow or "T"
1
45 degree elbow
1 ft
Horizontal pipe run
1ft
Vertical pipe run
Example: (3 x 1.22 m [4ft] of vertical length = 3.66 m [12 ft] x 0.5 = 6 EVL) +
(1 x elbow or "T" = 5 EVL) + (2 x 0.3 m [1 ft] of horizontal length = 2 EVL)
Total EVL = 13. So 76.2 mm (3 in) diameter vent is allowed.
note: At altitudes more than 914.4 m (3000 ft), we suggest the use of 102 mm (4 in)
diameter vent at an EVL of 2.13 m (7 ft) or more.
INSTALLATION CONFIgURATION:
Horizontally install through wall
nOTE: fOLLOw L-VEnT cHimnEy mAnufAcTuRER'S inSTRucTiOnS.
1.
Position the stove as Fig 1 & 2 and maintain the clearance specified in Fig. 3.
2.
Determine the position of hole in wall where directly behind stove exhaust vent
(refer to fig 4).
3.
Always maintain 152.4 mm (6 in) clearance from combustible materials.
4.
Refer to fig 7 for installation.
5.
Install L-vent wall thimble per L-vent manufacturer's instructions.
6.
Attach enough piping to go through and extend at least 152.4 mm (6 in) beyond
exterior wall. An 203.2 m (8 ft) vertical pipe run is suggested where possible to
reduce the possibility of smoke spillage caused by negative pressure.
7.
Attach cap and seal outside wall thimbles with non-hardening water-roof mastic.
8.
Note: Termination should not be located so that hot exhaust gases can ignite
trees, shrubs or grasses or be a hazard to children. Exhaust gases can reach
temperatures of 260˚C (500F) and cause serious burns if touched.
9.
Locate terminations: a) not less than 0.91 m (3 ft) above any forced air inlet
located within 3.05 m (10 ft); b) not less than 1.22 m (4 ft) below or horizontally
from, or one foot above, any door, window or gravity air inlet into any building;
c) not less than 0.61 m (2 ft) from an adjacent building and not less than 2.13 m
(7 ft) above grade when located adjacent to a public walkway.

1.
Follow L-Vent chimney manufacturer's instructions.
2.
Option – to achieve a centered vertical installation, a 45 degree elbow and a
clean-out tee can be used to offset the pipe from the exhaust outlet to the rear
center of the stove.
3.
Option – install L-vent elbow in place of clean-out tee. Locate stove. Drop plumb
bob to center of tee outlet, mark point on ceiling. Install ceiling support and
L-vent pipe as per L-vent manufacturer's instructions.
4.
Always maintain 76.2mm (3 in) clearance from combustible materials. When
passing through additional floors or ceilings, always install fire-stop spacer.
5.
After liner is up, cut either round or square hole in roof, always 76.2mm (3 in)
larger all the way around pipe. Install upper edge and sides of flashing under
roofing materials, nail to the roof along upper edge. Do not nail lower edge.
Seal nail heads with flexible waterproof sealant.
6.
Apply flexible, waterproof sealant where the storm collar meets the vent. Slide
storm collar down until it sits on the flashing. Seal and install cap.
