Venting and Combustion Air Options
Existing Vent System
DANGER
!
DO NOT install the SVF boiler into a common
vent with any other appliance. This will cause flue
gas spillage or appliance malfunction, resulting
in severe personal injury, death, or substantial
property damage.
WARNING
!
Follow all venting and piping instructions. Failure
to follow all instructions can cause flue gas
spillage and carbon monoxide emissions, which
can result in severe personal injury or death.
When replacing an existing boiler with an SVF boiler,
do not use the existing common vent The SVF boiler
requires its own vent and air piping as specified in
this manual If using a Category II system setup, see
additional venting requirements on pages 35-36
Removal of the previous boiler may cause an issue
for the appliances that remain on the old common
vent as the vent may be too large The following
test is intended to check for proper operation of the
appliances remaining on the old common vent system
