FUTERA III INSTALLATION AND OPERATION INSTRUCTIONS
Figure 6 – Vertical Venting with a Metal Chimney System
Vent Connections
Locate the boiler/water heater as close to the chimney as
possible. Use the shortest, straightest vent connector
possible for the installation. If horizontal runs exceed
5 ft
,
1.5 m they must be supported at
3 ft
,
0.9 m intervals with
overhead hangers. Use a single wall stainless steel vent
pipe the same diameter as the flue collar to connect the
boiler/water heater to a masonry chimney. When using a
listed metal chimney system use the appropriate vent
connector.
The vent connector should be sloped up toward the
chimney at a minimum rate of
1/4 in/ft
,
21 mm/m. On
masonry chimneys the connector must terminate flush with
the inside of the chimney flue, Figure 7. Fasten each single
wall vent connection with at least 3 corrosion resistant
sheet metal screws.
Always provide a minimum clearance of
6 in
,
152 mm
between single wall vent pipe and any combustible
materials.
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!
