Installation - Venting
Plan out the venting and wiring installation. Important notes to
consider when planning where the venting will be installed:
• Minimum total venting run allowed is 20 ft (6.1m), see boxed notes in Figures 2 & 3. If required
venting run is shorter than 20ft (6.1m) the replace must be direct vented. See replace installation manual
for further information regarding permitted venting and restrictions.
• Maximum total venting run allowed is 110 ft (33.5m) (V1+ H1+ V2+ H2+ H3+ H4+ H5), refer to
Figures 2 & 3.
• Maximum negative vertical run allowed is 4ft (1.2m) as measured from the elbow where it started
(see V2 in Figures 2 and 3).
• Multi-elbow installations are possible with a maximum of six (6) 90° elbows (two (2) 45° elbows is
equivalent to one (1) 90° elbow)
NOTE: A 90° elbow in the horizontal plane is equivalent to 3’ of vent and a 45°
elbow in the horizontal plane is equivalent to 1 1/2’, these equivalencies must be added
to the total vent length.
• IMPORTANT: This power vent kit has been approved for use with only Duravent 3” x 5” CVS Venting.
Specic venting adaptors are required (not included) for both the replace and power head to enable
the use of 3” x 5” CVS. Refer to Table 2 below for the required adaptors and part numbers.

to 4 x 6 5/8” reducer can also be ordered using Urbana Part #50-2321.
Table 2: CVS Vent Adaptors
• Venting Clearances: 1” (25 mm) clearance to combustibles must be maintained around any vertical vent
pipe. Around a horizontal vent pipe, the clearance to combustibles should be 2” (51 mm) above and 1” (25
mm) on the sides and bottom. When combustible materials are directly above a 90° elbow, 3” (76 mm) of
clearance is necessary. Additionally all venting clearances, within the chase, must be followed as listed in
the replace installation manual.

Installation - Exhaust Restriction
For proper operation, the correct restrictor setup is critical when power
venting an Urbana replace. The total vent length and number of elbows
is important where as horizontal and vertical length is less important.

Remember to consider elbows in the HORIZONTAL plane account for total vent length.
Calculate the total vent length accounting for horizontal plane elbows to conrm it is within the permitted limits and refer
to the chart below (Table 3) for the correct restrictor setup. Your climate and altitude may alter what restrictor is required
for your particular application. Figure 4 below shows how to install the disks required for the U30 & U50. Figure 5 below
shows how to install the bafe required for the U70. Refer to the replace’s manual for instructions regarding the restrictor
adjustment.

When using Propane (LP) - If desired, further restriction may be added to the replace to improve the ame
appearance. This is done by installing the venturi box cover plate supplied along with the replace’s manuals. Refer to
the replace installation guide for instructions regarding burner removal in order to access the open side of the venturi
box to install the cover plate. The venturi will still need to be correctly set.

Wiring - Fireplace
1. Wiring the pressure switch - The power vent kit utilizes a
pressure switch as a safety feature.
IMPORTANT: Proper wiring of the pressure switch is critical
for operation of the power vent circuit.
a. Locate the large white 10-pin connector at the front of the
IFC, this wiring harness will be modied
b. Locate the looped yellow wire within the wiring harness
of the large white plug shown in Figure 20. Note: the wiring
harness cable tie may need to be cut for slack, replace the
cable tie upon completion.
c. Cut the yellow looped wire at the center of the loop using
wire cutters.
d. Attach one of the supplied red wire taps to each of the cut
leads as shown in Figure 21. Install the wire taps roughly 1/2”
from the end of the leads. Make sure there is an audible click
upon closing the wire taps.
Note: the wires do not require stripping when using the
supplied wire taps.

2. Routing the 5-Wire Cable - Locate the unused electrical strain
relief at the bottom of cabinet back and route the supplied
5-wire cable through it (Figure 22). Feed enough cable through
to reach the IFC then tighten the strain relief.
Note - U30 models have an additional cover plate with a large
grommet in the middle that will need to be removed to access
the strain relief (Figure 22).

To complete the power vent installation the replace IFC must
be switched from direct vent mode into power vent mode.
IMPORTANT - Main power must not be connected prior to switching
to power vent mode or else IFC will remain in direct vent mode
To switch the IFC into power vent (PV) mode locate the replace switch panel at the front right corner of the cabinet
(Figure 23). The far left rocker switch with the cover above it controls the mode setting of the IFC. From the factory
the -symbol is down, press the rocker switch so that the O symbol is down. To clarify:
- symbol down = Direct Vent (DV) mode O symbol down = Power Vent (PV) mode
If for some reason the IFC needs to be switched back to DV mode simply press the switch again with main power
disconnected. This completes the power vent installation and now main power can be supplied to the replace. For
replace operation refer to the User Manual included with the replace.
