INSTALL PROBE ASSEMBLY ON THE FIREPLACE
Attach the probe assembly to appliance. The probe assembly (# 11
from Parts List) is of the same design as the unitized concentric pipe
components of the SV4.5 Secure-Vent System, featuring positive twist
lock connections (see Figure 4 ).
CAUTION: The probe assembly must be installed directly to the ap-
pliance collar. Install the probe assembly first before connecting any
other vent components to the fireplace.
All of the appliances that can be installed with this power vent kit, are
fitted with collars having locking inclined channels. The dimpled end of
the probe assembly fits over the appliance collar to create the positive
twist lock connection.
To attach the probe assembly to the appliance collar, align the dimpled
end over the collar, adjusting the radial alignment until the four locking
dimples are aligned with the inlet of the four inclined channels on the
collar (refer to Figure 4 ). Push the probe assembly against the collar
until it fully engages, then twist the probe assembly clockwise, running
the dimples down and along the incline channels until they seat at the
end of the channels. The unitized design of the probe assembly com-
ponents will engage and seal both the inner and outer pipe without the
need for sealant or screws.
Attach vent components to the probe assembly. Other vent sections
may be added to the previously installed probe assembly in accordance
with the requirements of the fireplace installation instructions and the
vent charts provided in the instructions.
