Direct Vent System (Flex) Installation Procedures - Regency Grandview G800C Owners & Installation Manual

installation
A poor draft, or down drafting can result from high
wind conditions near big trees or adjoining roof
lines, in these cases, increasing the vent height
may solve the problem.
7. Ensure vent is vertical and secure the base of
the flashing to the roof with roofing rails, slide
storm collar over the pipe section and seal with
a mastic.
8. Install the vertical termination cap by twist-
locking it.
Note: Any closets or storage spaces,
which the vent passes through must
be enclosed.

Installation
Procedures
1. Locate the unit in the framing, rough in the
gas (preferably on the right side of the unit)
and the electrical (Junction block is on the
left side) on the left. Locate the centerline of
the termination and mark wall accordingly.
Cut a 10"(254mm) hole in the wall (inside
dimension).
Note: A 1-1/2"(38mm) clearance around
the liner must be maintained
except that only a 1" (25mm)
clearance is needed at the termi-
nation end. We recommend fram-
ing a 10"(254mm) x 10"(254mm)
(inside dimensions) hole to give
structural rigidity for mounting
the termination.

Furring
Strips
Note: If installing termination on a
siding covered wall, furring strips
must be used to ensure that the
termination is not recessed into
M u r
the siding.
2. Level the fireplace and fasten it to the framing
using nails or screws through the nailing
Fourrures en bois
strips.
3. Assemble the vent assembly by applying
Mill Pac to the 4"(100mm) inner collar of the
termination and slipping the 4"(100mm) liner
over it at least 1-3/8" (35mm). Fasten with the
3 screws (drilling pilot holes will make this
easier). Apply Mill Pac to the 6-7/8"(175mm)
flex pipe and slip it over the 6-7/8" outer collar
of the vent terminal at least 1-3/8"(35mm)
and fasten with the 3 screws.
NOTE:Horizontal sections must be
supported at intervals not
exceeding 3 feet (0.9 meter).
(Flame picture and performance
will be affected by sags in the
liner).

4. Separate the 2 halves of the wall thimble and
securely fasten the one with the tabs to the
a l l outside wall making sure that the tabs are

on top and bottom. Fasten the other thimble
half to the inside wall. The thimble halves
slip inside each other and can be adjusted
see also c34020a.eps
for 2 x 4 or 2 x 6 walls. The liners must slip
over the collars a minimum of 1-3/8".
5. Slip the assembled liner and termination
assembly through the thimble making sure
the termination cap faces up (there are
markings on the cap that show which way
is up). This will position the termination cap
with proper down slope for draining water.
Fasten the cap to the outer wall with the 4
supplied screws.

6. Pull the centre 4"(100mm) liner and outer
french 6-7/8"(175mm) liner out enough to slip over
the flue collars of the fireplace. (You may
wish to cut the liner shorter to make it more
workable.) Do not bend liner more than 90
7. Apply Mill Pac over the fireplace inner collar
and slip the 4"(100mm) liner down over it
and attach with 3 supplied screws.
8. Do the same with the 6-7/8"(175mm) liner.
9. Apply a bead of silicone between the thimble
and termination and around the outer edge
of the terminal at the wall in order to keep
the water out.
IMPORTANT: Do not locate termination
hood where excessive snow or ice
buildup may occur. Be sure to check vent
termination area after snow falls, and clear
to prevent accidental blockage of venting
system. When using snow blowers, make
sure snow is not directed towards vent
termination area.
