The equivalent length of the vent system is the total length of straight pipe PLUS the equivalent length of all of the elbows. The following rules must also be followed: 1. Long radius (sweep) elbows are recommended. Standard elbows may be used, but since they have a longer equivalent length, they will reduce the total length of pipe that will be allowed. Short radius (plumbing vent) elbows are not allowed. The standard dimensions of the acceptable elbows are shown below. 2. The maximum equiv

FIGURE 11: Typical Suspended Furnace / Crawl Space Installation For modulating furnaces to be used in the downflow position, it is necessary to rotate the gas valve so that it is upright when the furnace is installed. Loosen the pipe union between the gas valve and manifold, rotate the valve as far upward as it will go, and tighten the union. See Figure 13, "Downflow Installation - Gas Valve Rotation".
