Vent Configurations
This appliance can only be vented vertically. The minimum vent height
measured from the floor under the unit to the bottom of the termination
is 10'. The maximum height that a vent can extend is 36'. The 30FID
uses 3" x 3" Co-linear venting, 34FID uses 4" x 3" Co-linear venting. This
is a direct vent unit and as such requires that both intake and exhaust
vents are connected and operational. Using existing flues as a partial
vent mechanism is not allowed. Due care is required to ensure that all
vent components are properly connected and sealed. Care must also
be taken when installing flashing or termination caps to make sure that
the structure of the building cannot be subject to water penetration.
Proper roofing and chimney finishing techniques must be used.
Steps for vent connection
** Before installing the venting system, make sure that any dampers or baffle
plates in the fireplace are removed or do not present any hindrance to your
installation **
1). Determine the length of flex venting that will be required. Cut 2 lengths a
couple of feet longer than you anticipate needing. The length of these needs
to be determined after the vent is stretched out. Flex venting generally comes
compressed and needs to be stretch out to meet the lengths as specified.
2). From the roof, attach the vent lengths to the adaptor. Don't forget to have
the flashing placed between the flex vent and the adaptor before attaching
the flex vent.
3). Using commercial grade sealant around the perimeter of the Collars of the
Adaptor, use a minimum of 3 Tech screws in each Vent.
4). Install the Termination to the top of Adaptor. Use a minimum of 4 tek screws
to attach the Termination to the Adaptor.
5). Feed the flex venting down the chimney until the adaptor is situated near the
top of the chimney. Use a commercial grade of sealant between the flashing
and the chimney top. Fasten the flashing to the top of the chimney using a
fastening method that will properly secure the flashing permanently.
6). Attach the adaptor to the top of the flashing using 4 tek screws. Seal around
the perimeter of the adaptor where it meets the flashing.
7). From inside the house check how long the vents protrude into the fireplace.
Read the section on installation where fuel supply pressure checking needs
to be done. This procedure can be done at this point by installing the venting
to the appliance prior to pushing the appliance into the fireplace cavity.
8). Once pre-installation steps have been completed, trim the vent length to
the correct length for installation. The correct length will leave the flue collar
slide plate suspended around 18-19 inches from the floor of the fireplace.
9). Remove the flue collar slide plate from the appliance. Attach both flex ends
to the Flue Collar Slide plate. Use a commercial high temp sealant around
the Flue Collars on Flue Collar Slide Plate before installing the Venting. Use a
minimum of 3 tech screws to properly secure the Venting to the Flue Collar
Slide Plate.
** Make certain that the Exhaust and Intake Vents are connected to the correct
collars on the Flue Connection Plate. If they are connected in reverse, this
unit will not operate and re-installation will be necessary. **
