GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

CHIMNEY & VENT PIPE CONNECTIONS

WARNING: The vent installation must be in accordance with Part 7,Venting of Equipment, of the National Fuel Gas Code, ANSI Z223.1/NFPA54- latest revision or applicable provisions of the local building codes. Canadian installa-tions must comply with CAN /CGA B149.1 or .2 Installation Code. Improper venting of this boiler can result in excessive levels of carbon monoxide, which can result in severe personal injury or death!

Chimney Inspection & Sizing

If this boiler will be connected to a masonry chimney, a thorough inspection of the chimney must be performed. Ensure that the chimney is clean, properly constructed and properly sized. Table 2 lists the equivalent breeching and flue sizes required for the GB300 boilers.

NOTE: These sizes are based on a 20 foot chimney height.

When more than one appliance is connected to the same chimney flue the flue must be large enough to safely vent the combined output of all the appliances.

WARNING: If an appliance using any type of a mechanical draft system operating under positive pressure is connected to a chimney flue, never connect any other appliances to this flue. Doing so can result in the accumulation of carbon monoxide which can cause severe personal injury or death!

VENT CONNECTIONS

Always use a type B or single wall galvanized metal vent pipe the same diameter as the draft hood flue collar. Use the shortest, straightest vent system possible for the installation. If horizontal runs exceed 6 feet they must be supported at maximum 6 foot intervals with overhead hangers. The vent system should be sloped up towards the chimney at a minimum rate of 1/4 inch/foot and terminate flush with the inside of the chimney flue. Fasten each connection with at least 3 corrosion resistant sheet metal screws.

WARNING: Never modify or alter any part of the boiler’s draft hood. This includes the removal or alteration of any baffles. Never install a vent pipe of a diameter different than that of the boiler draft hood flue collar. Failure to comply with this warning can result in severe personal injury or death.

Always provide a minimum clearance of 6 inches between type C 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 any combustible material can result in a fire causing extensive property damage, severe personal injury or death!
