VENTING
THE APPLIANCE MUST NOT BE CONNECTED TO A CHIMNEY
FLUE SERVING A SEPARATE SOLID FUEL BURNING APPLIANCE.
This appliance is designed to be attached to two 3" (76mm) co-linear aluminium flex running the full
length of the chimney connector from the unit to the support box. The flue length must be a minimum
length of 8' (2.44m) and a maximum of 35' (10.7m).
Periodically check that the vent is unrestricted. Masonry chimneys may take various contours which
the flexible liner will accommodate. However, keep the flexible liner as straight as possible, avoid un -
necessary bending.
Alternative Approved Venting Components*
46DVA-VCH High Wind Cap 46DVA-GK 3" Co-linear Adaptor with flashing
We recommend using the Simpson Dura-Vent System 46DVA-GK adapter and 46DVA-VCH high-wind
cap. The Air Intake pipe must be attached to the inlet air collar of the termination cap.
*NOTE: Simpson Duravent can only be used with 3" liners.
For additional venting options see page 11 of the Regency L234 Manual provided in this manual.
The unit is a vented appliance and must be connected to a chimney/flue in accordance with the
code, using the chimney manufacturer's instructions.
The 34ZDV is installed with the use of 2 - 3"
flex tubes. One for the exhaust and one for the
air intake. It is very important to connect them
to the correct couplings. The Exhaust must be
connected to the Exhaust fitting at the sup -
port box. The Intake must be connected to the
Intake connector. If the flex tube is cut mark the
ends prior to cutting.
Step 1.
The Dura Vent DirectVent Pro 4" x 6
5/8" coaxial pipe must have a 1" clearance to
combustibles when passing through ceilings,
walls, roofs, enclosures, attic rafters, or other
nearby combustible surfaces. Do not pack air
spaces with insulation. Check the appliance
manufacturer’s instructions for maximum verti -
cal rise of the venting system and any maxi -
mum horizontal offset limitations.
The support box must be mounted in the ceil -
ing. The placement must be in an area that is
clear of roof rafters or joists. Avoid hip supports or
engineered rafters or beams. Elbows are available
that should in most installations allow you to avoid
these areas. Follow DuraVent's instructions for the
proper installation of their DirectVent Pro 4" x 6
5/8" pipe that is run from the support box through
the roof.
The 3" Flex and Dura Vent DirectVent Pro venting is
available from your dealer or directly from Malm. It
is not included in the price of the unit.
Step 2.
Set the Zircon in the desired location.
Drop a plumb bob down from the ceiling to the
position of the appliance flue exit, and mark the
location where the vent will penetrate the ceiling.
Drill a small hole at this point. Next, drop a plumb
bob from the roof to the hole previously drilled in
the ceiling, and mark the spot where the vent will
penetrate the roof (Fig. 13). Determine if ceiling
