Mechanical systemmay be required.Direct Vent, Positive Pressure,Cateory IVIn this configuration the boiler blower is used to push theflue products to the outdoors while drawing combustion airfrom the outdoors. The Intake Air Option instructions under the“COMBUSTION AIR & VENTILATION” section must befollowed! The vent system must be sized per Table 4.Horizontal Direct Vent SystemsFigures 1 & 2The vent materials used in horizontal vent systems must be certifiedto UL 1738 for installations in the United States, ULC S636 forinstallations in Canada. The certifi ed vent terminal from RBI mustalso be used.If any part of a single wall metal vent system passes through anunheated space, it must be insulated with insulation rated for 400°F,204°C. Structural penetrations must be made using approved fi re-stops. For best results, horizontal vent systems should be as shortand straight as possible.The vent system must be both gas tight and watertight. All seamsand joints in metal pipes must be joined and sealed in accordancewith the vent system manufacturer’s instructions.When horizontal vent runs exceed 5 ft, 1.5 m they must be supportedat 3 ft, 0.9 m intervals with overhead hangers. The vent systemmust be pitched down, toward the vent terminal, 1/4 in/ft, 20 mm/m.If any part of a single wall metal vent system passes through anunheated space it must be insulated with insulation rated for 400°F,204°C.Horizontal vent systems shall terminate at least 4 ft, 1.2 m below,4 ft, 1.2 m horizontally from or 1 ft, 0.30 m above any door, windowor gravity air inlet into any building. It must not terminate less than4 ft, 1.2 m horizontally from, and in no case above or below, unlessa 4 ft, 1.2 m horizontal distance is maintained, from electric meters,gas meters, regulators and relief equipment and not less than 7 ft,2.1 m above adjacent public walkway. The bottom of the ventterminal(s) shall be located at least 5 ft , 1.5 m above the air intaketerminal(s) unless there is a minimum 5 ft, 1.5 m horizontalseparation between them. Avoid terminal locations likely to beaffected by winds, snowdrifts, people and pets. Protect buildingmaterials and vegetation from degradation caused by the fl ue gases.Vertical Direct Vent Systems – Figure 3If any part of a single wall metal vent system passes through anunheated space, it must be insulated with insulation rated for 400°F,204°C. Structural penetrations must be made using approved fi re-stops.An approved, nonrestrictive vent terminal must be used. The topof a vertical vent system must extend at least 5 1/2 ft, 1.7 m abovethe roof surface and maximum snow line that it passes through,4 ft, 1.2 m above the intake air terminal, see Figure 3.In addition the vent system must conform to the dimensions shownin Figure 3. The penetration point in the roof must be properlyflashed and sealed.The vent system must be gas tight. All seams and joints in metalpipes must be joined and sealed in accordance with the vent systemmanufacturer’s instructions.Combination Direct Vent Systems – Figure 4The boiler can be vented vertically with the intake air pipedhorizontally through an outside wall. Follow the instructions in theIntake Air Option – Horizontal Guidelines on page 5. Also followthe general instructions in the “COMBUSTION AIR &VENTILATION” and “GENERAL VENTING GUIDELINES”sections.
