2.Locate the vent terminal so the vent exhaust does not settle on building surfaces and other nearby objects. Vent products may corrode such surfaces or objects.

3.Locate the vent terminal at a sufficient horizontal distance from any gas or electric metering, regulating or relief equipment. In the United States, this distance must be at least 4 feet

(1.21 m). In Canada, it must be at least 10 feet (3.04 m).

4.Locate the vent terminal at a sufficient horizontal distance from any building opening. Take special care to assure that combustion products do not enter a building through windows, doors, ventilation inlets, etc. In the United States, this distance must be at least 4 feet (1.21 m). In Canada, it must be at least 10 feet (3.04 m).

As shown in Figures 8 and 9, the combustion air intake and the vent outlet must be installed no closer together than 18" (45.7cm) and no farther apart than 60" (1.5m). The combustion air inlet opening must face downward to prevent entry of rain or snow. The vent outlet must discharge away from the combustion air inlet - normally in a horizontal direction when on a wall and vertically upward when on a roof. Both should terminate at least 12" (30.5cm) above the snow accumulation level. In locations with freezing climate, extension of the vent pipe outside of the building should be minimized. The insect screens provided with the heater must be installed at the combustion air and vent pipe openings as shown in Figure 10. Insect screens are sized to fit the inside of a 5" PVC pipe fitting. Trim them as necessary for smaller pipe sizes.

Connect the vent pipe to the heater vent collar with an air-tight corrosion-resistant clamp. The connection must not allow leakage of combustion products into the space but should be removable for service. See Figure 7.

Connect the combustion air pipe to collar of the air filter box. For this combustion air pipe only, sheet metal pipe is most convenient and can be screwed directly to the collar. Seal the joint with silicone sealer or similar mastic material.

Install vent piping with a continuous rise of at least 1/4" per foot (20 mm per meter) away from the heater. This will assure that any condensate forming in the vent pipe will flow back to the heater where it can be disposed of properly.

Support vent piping with suitable hangers so its weight does not bear on the heater or building penetration and so that piping joints are not strained. Support horizontal runs at intervals no greater than

6 feet (1.82 meters), and closer if necessary to avoid sagging. Sagging can trap condensate water and block the vent.
