Using RA24CA - Co-axial Vent Plate and 590FVK2 -
Co-axial 3” x 5” Flex and Terminal Adapter/Flashing
IMPORTANT: This appliance’s venting system is room sealed and

process.
1. Stretch 3” and 5” liners individually to required length. Insert
3” liner inside 5” liner and rough-in vent liners into the existing
chimney system from the roof. Be careful not to tear or
damage the liners in the process. Verify there is plenty of liner
at the bottom to facilitate the connection of the liners to the
vent slider so you will not need to stretch more later.
2. Trim the Terminal Adapter & Flashing as required to suit top of
chimney and fold a drip edge if desired.
3. Trim ends of liner if necessary and fasten to collars on the
underside of the terminal adapter using sheet metal screws
and gear clamps provided. Ensure liners are well secured and
will not fall down the chimney.
4. Apply a bead of sealant to top of chimney and
seat fl ashing onto sealant.
5. a) Larger cavity opening
Slide the appliance into the cavity.
b) Smaller cavity opening
Secure the liners to the vent plate.
6. Apply RTV sealant to each of the collars on the
vent slider and fi t the two liners. Secure with 4
tapping screws per liner and stainless steel gear
clamps provided. If the vent slider is secured to
the liners fi rst, slide
the fi rebox onto
the vent slider in
the cavity taking
care not to damage
the liners.
Make
sure that the rear
edge of the slider
is hooked over
the cleat on the
fi rebox.
Secure the
vent slider to the
front of the fi rebox
with two screws
removed earlier.
