Equivalent Vent Length (EVL)

INSTALLATION

Equivalent Vent Length (EVL)

The longer the run of pipe in your installation (both with insert and freestanding models), the more restriction there is in the system. Therefore, larger diameter pipe should be used.

Use 4” pipe if you have more than 15 feet of equivalent vent length.

Horizontal runs shall not exceed 10 feet of EVL.

Recommended vertical runs to 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, we suggest the use of 4” diameter vent at an EVL of 7 feet or more.

FREESTANDING INSTALLATIONS

A.ASSEMBLING PEDESTAL OR LEG SET

If using a pedestal, follow the instructions inside the Breckwell P23 Pedestal w/ Ashpan Part # A-P23-PNEW

(Refer to figure 8).

If using cast legs, follow the instructions inside the Breckwell P23

Leg Set w/ Ashpan Part # A-CGL-NEW or # A-CL-NEW.

Legs are installed by using the four bolts provided in the kit into the four holes under the stove at each corner, thread on nuts from the top and tighten. Make sure to save the hole plugs.

NOTE: If converting from legs to pedestal the hole plugs must be installed in the unused holes.
