GS110 DIRECT VENT BOILER INSTALLATION AND OPERATION INSTRUCTIONS

Page 11

Horizontal vent systems shall terminate at least 4 feet (1.3 m) below, 4 feet (1.3 m) horizontally from or 1 foot (0.23 m) above any door, window or gravity air inlet into any building. It must not terminate less than 4 feet (1.3

m)horizontally from, and in no case above or below, unless a 4 feet (1.3 m) horizontal distance is maintained, from electric meters, gas meters, regulators and relief equipment and not less than 7 feet (2.3 m) from any adjacent public walkway. The bottom of the vent terminal(s) shall be located at least 5 feet (1.5 m) above the air intake terminal(s). Avoid terminal locations likely to be affected by winds, snowdrifts, people and pets.

VERTICAL DIRECT VENT SYSTEMS

See Figures 6 & 10. The vent materials used in vertical positive pressure vent systems must be certified to UL 1738 for installations in the United States, ULS636 for installations in Canada.

The maximum length for the vertical vent system is listed in Table 4. Each 90° elbow is equal to 5 linear feet (1.5 m) of pipe. To maximize the performance of single wall sheet metal vent systems locate 90° elbows as far from the boiler as possible and from one another. If any part of a single wall metal vent system passes through an unheated space it must be insulated with insulation rated for 400°F. Structural penetrations must be made using approved fire-stops.

The vent system must be both gas tight and watertight. All seams and joints in metal pipes must be joined and sealed in accordance with the vent system manufacturer’s instructions.

Vertical vent systems must be terminated with an approved terminal cap as shown in Figures 6 & 10.

HORIZONTAL VENT

POSITIVE PRESSURE SYSTEMS

See Figure 3. The vent materials used in horizontal positive pressure vent systems must be certified to UL 1738 for installations in the United States, ULS636 for installations in Canada.

The maximum vent lengths are listed in Table 3.

Each 90° elbow is equal to 5 linear feet (1.5 m) of pipe. To maximize the performance of single wall sheet metal vent systems locate 90° elbows as far from the boiler as possible and from one another. Horizontal vent systems should be as short and straight as possible.

When horizontal vent runs exceed 5 feet (1.5 m) they must be supported at 3 foot (0.98 m) intervals with overhead hangers. The vent system must be pitched down, toward the vent terminal, 1/4" per foot (21 mm per meter). If any part of a single wall metal vent system passes through an unheated space it must be insulated with insulation rated for 400°F. Structural penetrations must be made using approved thimbles.

The vent system must be both gas tight and watertight. All seams and joints in metal pipes must be joined and sealed in accordance with the vent system manufacturer's instructions.

Horizontal vent systems shall terminate at least 4 feet (1.3 m) below, 4 feet (1.3 m) horizontally from or 1 foot (0.23 m) above any door, window or gravity air inlet into any building. It must not terminate less than 4 feet (1.3

m)horizontally from, and in no case above or below, unless a 4 feet (1.3 m) horizontal distance is maintained, from electric meters, gas meters, regulators and relief equipment and not less than 7 feet (2.3 m) from any adjacent public walkway. The bottom of the vent terminal(s) shall be located at least 5 feet (1.5 m) above the air intake terminal(s). Avoid terminal locations likely to be affected by winds, snowdrifts, people and pets. Protect building materials and vegetation from degradation caused by flue gasses.
