GS110 DIRECT VENT BOILER INSTALLATION AND OPERATION INSTRUCTIONS

GENERAL VENTING GUIDELINES

WARNING: The vent installation must be in accordance with Part 7, Venting of Equipment, of the National Fuel Gas Code, ANSI Z223.1/ NFPA 54-latest revision or applicable provisions of the local building codes. Canadian installations must comply with CSA B149.1 or

.2 Installation Code. Improper venting can result in excessive levels of carbon monoxide which can result in severe personal injury or death!

WARNING: Thimbles and fire-stops must be used where required. A minimum clearance of 6" must be maintained between single wall metal vents and combustible construction or a fire resulting in severe personal injury or death may occur!

WARNING : Each boiler/water heater must have it's own vent system. Common positive pressure vent systems are not to be used! Improper installation can result in excessive levels of carbon monoxide which can cause severe personal injury or death!

All vent systems must be fully supported by the building structure and not by the boiler/water heater.

Certified vent systems are manufactured by the following companies:

GENERAL DIRECT VENT INFO

In this configuration the boiler blower is used to push the flue products to the outdoors while drawing combustion air from the outdoors. The instructions under the COMBUSTION AIR & VENTILATION SECTION must be followed! The vent system must be sized per Table 3.

VENT SYSTEM OPTIONS

The GS110 may be vented the following ways:

1)Direct Vent (Positive Pressure), uses a vent system certified to UL 1738 for installations in the United States, ULS636 for installations in Canada. Combustion air is piped from the outdoors to the blower inlet.

2)Horizontal Vent (Positive Pressure), uses a vent system certified to UL 1738 for installations in the United States, ULS636 for installations in Canada. Combustion air is obtained from the space in which the unit is installed.

3)Vertical Vent (Positive Pressure), uses a vent system certified to UL 1738 for installations in the United States, ULS636 for installations in Canada. Combustion air is piped from the outdoors to the blower inlet or is obtained from the space in which the unit is installed.

4)Vertical/Chimney Vent (Negative Pressure), uses an approved metal chimney system or masonry chimney. Combustion air is obtained from the space in which the unit is installed or is piped from the outdoors to the blower inlet.

* 4" to 3" reducer required

Note: Subtract 5 feet (1.5 m) for each 90° elbow.

HORIZONTAL DIRECT VENT

SYSTEMS

See figures 7 & 8. 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.

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. For best results, horizontal vent systems should be as short and straight as possible. 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.

When horizontal vent runs exceed 5 feet (1.5m) 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 (21mm 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.
