GV100W BOILER
INSTALLATION & OPERATING INSTRUCTIONS
Vent Connections to Chimneys
Use Type B1 or single wall metal vent pipe from the boiler to the chimney. If used, a 4 in to 5 in, 102 mm to 127 mm increaser must be fastened directly to the boiler vent collar with sheet metal screws no longer than 1/2 in, 13 mm. Use the shortest, straightest vent system possible for the particular application. The vent system should be sloped up toward the chimney 1/4 in/ft, 2 cm/m. Ensure that the flue pipe is properly supported and each connection securely fastened with at least 3 corrosion resistant sheet metal screws. The termination of the vent pipe must be flush with the inside of the chimney flue.
Always provide a minimum clearance of 6 in, 152 mm, between single wall metal vent pipe and any combustible materials. Type B1 vent may be used, clearance between it and any combustible material must be as listed.
WARNING: Failure to maintain minimum clearances between vent connectors and combustible materials can result in a fire causing extensive property damage, severe personal injury or death!
FIG NO. 4 Chimney Venting
CHIMNEY
Single Wall Metal Vent
GV100W boilers may be vented vertically using single wall metal vent pipe sized per Table 1. Galvanized sheet metal pipe must have a minimum wall thickness of 26 gauge. In Canada, pipe constructed of .025 in, 0.63 mm, thick aluminum or .018 inch thick stainless steel may be required.
The use of thimbles, firestops and other protective devices when penetrating combustible or noncombustible construction must be in accordance with all applicable national and local codes.
WARNING: Single wall vent pipe must NEVER pass through interior walls or through floors or ceilings! Failure to comply with this warning could result in a fire causing extensive property damage, severe personal injury or death!
An unused chimney flue can be used as a raceway for single wall metal pipe, see FIG. NO. 4A.
WARNING: Never run vent pipe through a chimney flue that has another appliance attached to it! Never connect another appliance to a pressurized vent system, it must serve only one appliance. Failure to comply with this warning can result in excessive levels of carbon monoxide causing severe personal injury or death!

CLEANOUT
A listed vent terminal designed for the type of pipe being used must complete the vertical run where it exits the chimney. If the chimney is on an outside wall or in an unheated space the optional condensate tee and trap pictured in FIG. NO. 4A may be required. The trap is made by
Do not operate the boiler without this trap!

CHIMNEY
VERTICAL VENTING
B Vent
The boiler may be vented vertically using the proper size Type B1 vent pipe. Do not use the boiler as a load bearing element. The vent system must be fully supported by the building structure. Use an approved vent terminal at the vent outlet which must extend at least 3 ft, 1 m, above the highest point where it passes through the roof. In addition, the vent pipe must be at least 2 ft, 0.6 m higher than any portion of the building within a horizontal distance of 10 ft, 3 m.
