WARNING
Do not combine the flue from this unit with the vent from any other appliance. Do not combine flues from
multiple appliances into a common vent. The flue from this unit must be a dedicated stack.
Connect the flue vent directly to the flue outlet opening on the top of the unit. Make the connections from the unit vent to
the outside stack as direct as possible with no reduction in diameter. Provide adequate clearance to combustibles for the vent
connector and firestop. Follow the vent manufacturer’s instructions when installing sealed AL29-4C vents and accessories, such as
firestop spacers, vent connectors, thimbles, caps, etc.
Provide adequate clearance to combustibles for the vent connector and firestop.
When planning the venting system, avoid possible contact with plumbing or electrical wiring inside walls, ceilings, and floors.
Locate the unit as close as possible to chimney or gas vent. When a vent system is disconnected for any reason, the flue must be
reassembled and resealed according to the vent manufacturer’s instructions.
The installed length of flue from the unit to the outside point of termination must not exceed 50 equivalent feet (15.2 m). Subtract
5 feet (1.5 m) of equivalent length for each 90° elbow. Subtract 2.5 feet (0.7 m) of equivalent length for each 45° elbow.
