With flexible venting,in conjunction with the various terminations, use either the 5 foot (1.5m) vent kit GD420 or the 10 foot (3.1m) vent kitGD430.For optimum flame appearance and appliance performance, keep the vent length and number of elbows to aminimum.The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verifythat it is unobstructed and undamaged.Rigid and flexible venting systems must not be combined. Different venting manufacturer components mustnot be combined.These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable horizontalrun is 20 feet (6.1m). The maximum allowable vertical vent length is 40 feet (12.2m). The maximum number of ventconnections is two horizontally or three vertically (excluding the appliance and the air terminal connections) whenusing flexible venting.Horizontal runs may have a 0” (0mm) rise per foot/meter however for optimum performance it is recommendedthat all horizontal runs have a minimum 1/4” (6.4mm) rise per foot/meter using flexible venting. For safe and properoperation of the appliance, follow the venting instructions exactly.A terminal shall not terminate directly above a sidewalk or paved driveway which is located between two single familydwellings and serves both dwellings. Local codes or regulations may require different clearances.Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1¼”(31.8mm) air gap all around between the inner liner and outer liner is required for safe operation.8.3_1A3.2 TYPICAL VENT INSTALLATIONS36”(914MM)
