A poor draft, or down drafting can result from high wind conditions near big trees or adjoin- ing 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
for Regency Direct Vent
System (Flex)
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 dimen- sion).
Note: To make the installation more a e s t h e t i c a l l y pleasing, we rec- ommend framing out a square to mount the termi- nal to.
Note: A
Note: If installing termination on a siding covered wall, furring strips must be used to ensure that the termi- nation is not recessed into the siding.
2)Level the fireplace and fasten it to the framing using nails or screws through the nailing 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
NOTE: Horizontal sections must be sup- ported 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 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 for 2 x 4 or 2 x 6 walls. The liners must slip over the collars a minimum of
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 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 90o.
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
9)Apply a bead of silicone between the thim- ble 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 af- ter snow falls, and clear to prevent accidental block- age of venting system. When using snow blow- ers, make sure snow is not directed towards vent termination area.
