Caution Requirements The top, back and sides of the fireplace are defined by
standoffs. The metal ends of the standoff may NOT be recessed into combustible construction.
WARNING
Fire hazard is an extreme risk
if these clearances (air space) to combustible materials are not adhered to. It is of greatest importance that this fireplace and vent system be installed only in accordance
with these instructions.

With the lift handles adding approximately 4 inches to the overall width of the appliance,In cases where the appliance would need to be raised off the ground in order to slide it into the framed opening, it is suggested that either the framing width change from 78″ to 82″ so that the appliance could be easily slid into position with the handles remaining on the appliance, or alternatively create a platform in front of the framed opening where the lift handles could be removed prior to sliding the appliance into its final position. Alternatively, If raised off the ground, the framing could be installed afterwards once appliance has been put into place and lift handles removed in order to keep the framing width at 78″. Ensure that the wood base that the appliance will sit on is strong enough to support the full weight of this appliance. The overall weight of this appliance is 529 pounds (shipping weight).
Note: A combined minimum of 288 square inches of open area is required for the convection air outlet to cool the enclosure. Ensure clearances for Convection Air Outlets are met. See clearances CV72E in this manual as there are different methods as to how this can be achieved.

Note: This appliance must be installed on a solid surface such as a plywood floor which must be the full width and depth of the appliance.

Venting Introduction
The CV72E uses the “balanced flue” technology Co-Axial system. The inner liner vents products of combustion to the outside while the outer liner draws outside combustion air into the combustion chamber thereby eliminating the need to use heated room air for combustion and losing warm room air up the chimney. Note: These flue pipes must not be connected to any other appliance. The gas appliance and vent system must be vented directly to the outside of the building, and never be attached to a chimney serving a separate solid fuel or gas burning appliance. Each direct vent gas appliance must use it’s own separate vent system. Common vent systems are prohibited.
Venting Arrangement for Horizontal Terminations
The diagram shows all allowable combinations of vertical runs with horizontal terminations, using one 90o (two 45o elbows equal one 90o elbow). Note: Must use optional rigid pipe adapter (Part# 770-994) when using Rigid Pipe Venting Systems)
55-1/4″ (1403mm)
VENT RESTRICTOR SETTING: Vent restrictor factory set at Set 0. Refer to the “Vent Restrictor Position” section for details on how to change the vent restrictor from the factory setting of Set 0 to Set 2 if required. Note: For horizontal terminations the Regency Direct Vent Flex System may be used for installations with
a maximum continuous vent length of up to 10 feet. If longer runs are required, rigid pipe must be used. · Maintain clearances to combustibles as listed in “Clearances” section · Horizontal vent must be supported every 3 feet. · Firestops are required at each floor level and whenever passing through a wall. · A vent guard should be used whenever the termination is lower than the specified minimum or as per local codes. 8 | City Series® CV72E-12 Direct Vent Gas Fireplace

Horizontal Terminations – Flex Vent 5″ x 8″
These venting systems, in combination with the CV72E Direct Vent Gas Fireplace, has been tested and listed as a direct vent heater system by Intertek. The location of the termination cap must conform to the requirements in the Vent Terminal Locations diagram in “Exterior Vent Termination Locations” section.
Regency® Direct Vent (Flex) System Termination Kits include all the parts needed to install the CV72E using a flexible vent.

Horizontal Terminations – Rigid Pipe 5″ x 8″
The minimum components required for a basic horizontal termination are:
1 Horizontal Termination Cap 1 Rigid Pipe Adaptor (770-994) 1 Wall Thimble 1 Length of pipe to suit wall thickness
(see chart)
Wall thickness is measured from the back standoffs to the inside mounting surface of termination cap. For siding other than vinyl furring strips may be used, instead of the vinyl siding standoff, to create a level surface to mount the vent terminal. The Terminal must not be recessed into siding. Measure the wall thickness including furring strips.
If a Vinyl Siding Standoff is required (it must be used with vinyl siding), measure to outside surface of wall without siding and add 2 inches.

WARNING:
Do not combine venting components from different venting systems.
However use of the the AstroCapTM and FPI Riser is acceptable with all systems.

This product has been evaluated by Intertek for using a Rigid Pipe Adaptor in conjunction with Duravent Direct-Vent, Selkirk Direct-Temp, Ameri Vent Direct Venting, ICC Excel Direct, Olympia Ventis DV, and Security Secure Vent systems. Use of these systems with the Rigid Pipe adaptor is deemed acceptable and does not affect the Intertek WHI listing of components.

When using Rigid Vent other than Simpson Dura-Vent, 3 screws must be used to secure rigid pipe to adaptor.

The FPI AstroCapTM and FPI Riser Vent terminal are certified for installations using FPI venting systems as well as Simpson Dura-Vent® Direct Vent, American Metal Products Ameri Vent Direct Vent, Security Secure Vent®, ICC Excel, Olympia Ventis DV, Selkirk Direct-Temp.

Vertical Terminations – Rigid/Flex Pipe 5″ x 8″
The minimum components required for a basic vertical termination are:

(see chart)

Vertical Terminal
Storm Collar Flashing

Galvanized pipe is desirable above the roofline due to its higher corrosion resistance. Continue to add pipe sections through the
flashing until the height of the vent cap meets the minimum height requirements specified in table below or local codes. Note that for steep roof pitches, the vertical height must be increased. 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.

2. Direct Vent pipe and fittings are designed with

special twist-lock connections to connect the

58-3/16″ (1478 mm)

venting system to the appliance flue outlet. A

twist-lock appliance adaptor is required. 3. In conjunction with the Approved Vent system,

install the adaptor after the unit is set in its de-

sired location. Slip the adapter over the existing

inner and outer flue collar. Fasten to the outer collar only with the 3 supplied screws (drilling

pilot holes will make this easier).

4. Level the fireplace and fasten it to the framing using nails or screws through the top and side
nailing strips.

tall Snorkel Terminations are available, as well

as the standard Riser Vent. Follow the same

5. Assemble the desired combination of pipe and elbows to the appliance adaptor and twist-lock for a solid connection.

Below Grade Snorkel Installation If the snorkel termination must be installed below grade, i.e. basement application, proper drainage must be provided to prevent water from entering the snorkel termination. See diagram 56. Do not attempt to enclose the snorkel within the wall or any other type of enclosure.
Diagram 4 7. Ensure that the pipe clearances to combustible
materials are maintained (Diagram 55). Install the termination cap. Note: If installing termination on a vinyl
siding covered wall, a vinyl siding standoff or furring strips must be used to ensure that the termination is not recessed into the siding.
Diagram 5
The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete, or other types of sidings. 8. Before connecting the horizontal run of vent pipe to the vent termination, slide the Wall Thimble over the vent pipe. The wall thimble is required for all horizontal terminations. 9. Slide the appliance and vent assembly towards the wall carefully inserting the vent pipe into the vent cap assembly. It is important that the vent pipe extends into the vent cap sufficient distance so as to result in a minimum pipe overlap of 1-1/4 inches (32mm). Secure the connection between the vent pipe and the vent cap.
