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.WARNING:WARNING:CAUTION:CAUTION:INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.DO NOT INSTALL IN BEDROOMTHE STRUCTURAL INTEGRITY OF THE MANUFACTURED HOME FLOOR, WALL, ANDCEILING/ROOF MUST BE MAINTAINEDTHE CHIMNEY CONNECTOR SHALL NOT PASS TROUGH AN ATTIC OR ROOF SPACE,CLOSET OR SIMILAR CONCEALED SPACE, OR A FLOOR, OR CEILING.1.6.1. Equivalent Vent Length (EVL)The longer the run of pipe in your installation, thegreater the restriction in your system. A wider pipeis recommended when the system’s run is long. Always use 4” pipe if you have more than 15”Equivalent Vent Length (EVL). Horizontal runs shall not exceed 9 feet. Never exceed 30 feet of EVL.To calculate EVL, use the following conversionstable:Qty Type of pipe EVL equivalent(ft)1 90° elbow or “T” 51 45° elbow 31 ft Horizontal pipe run 11 ft Vertical pipe run 0.5NOTE: If the stove is located at an altitude of 3,000 feet or more, it isrecommended to use a 4'' diameter venting system if the ELV is 7 feet ormore.Here is an example on how to calculate the EVL ofyour installation. (See Figure 9):FIGURE 10Venting through wall(3 x 4’ of vertical length = 12’ x 0.5 = 6 EVL) +(1 x elbow or "T" = 5 EVL) +(2 x 1’ of horizontal length = 2 EVL)Total EVL = (6 + 5 +2) = 13. Therefore, the use ofa 3" pipe is permitted.Note: Do not include the exterior wall termination (swan neck) in thecalculation of the EVL.
