Duraconnect I - DuraVent BV Installation Instructions Manual

DURACONNECT I

DuraConnect I is a Single Wall Expandable
Flex Gas Vent Connector, designed for use
as a connector for Listed gas fired appliances
equipped with draft hoods and other appli-
ances Listed for use with Type B Gas Vent.
DuraConnect I is designed to simplify a
connection between a gas burning appliance
and Type B Gas Vent systems by eliminating
the need for a separate draft hood connec-
tor, straight pipe and elbows, removing the
guess work of height interference sometimes
associated with fixed lengths of rigid single
wall or Type B Gas Vent.
Individual lengths are provided with the
same type of outlet end connector as
DuraVent Model BV Type B Vent, permit-
ting simple attachment. The DuraConnect
I Single Wall Expandable Flex Connectors
are available in 3" and 4" diameters and can
extend from 24" to 42" (3EFC) and from 30"
to 60" (5EFC) in length, allowing a greater
range of installations (see Figure 26).
DuraConnect I Expandable Flex Connector
is Listed by Underwriters Laboratories (UL)
for 1" (25mm) airspace clearance to com-
bustibles in an unenclosed installation. At no
time should this product be fully enclosed or
pass through a combustible area such as a
ceiling, attic, wall, roof joist, or crawl space.

b) Make no unnecessary bends;
c) Make no bends greater than 90 degrees;
d) Make bends as smooth as possible with
no dips or sags;
e) Install with at least a 1/4" per foot (20mm/m)
rise.

- To extend the
DuraConnect I, grasp
both ends and pull in
opposite directions until
the desired length is
achieved.
To install: Extend inlet end down over collar
of appliance draft hood and secure in place
with minimum 3 screws (not supplied) through
the inlet end extension of the DuraConnect I
and the collar of draft hood (see Figure 28).
With the DuraConnect I Inlet End secured to
the draft hood, extend to the required length
and secure the Outlet End of DuraConnect I
to the inlet end of the Type B Gas Vent.
Never cut or modify DuraConnect I length.
If necessary, the connector length may be
slightly compressed to obtain proper length
(see Figure 27). Extra care must be observed
when bending the flexible connector in the
compressed state.
The DuraConnect I is packaged in a slightly
compressed mode. To extend to the required
length stretch the DuraConnect I to the de-
sired length by grasping the ends and pulling
in opposite directions. This may be an easier
task for 2 people or by attaching the inlet end
to the water heater's draft hood first.
