Mantels
The height that a combustible mantel is fitted above the fireplace is dependent on the depth of the mantel. This also applies to the distance between the mantel leg (if fitted) and the fireplace.
For the correct mounting height and widths refer to Figs. 4a and 4b, and the following Mantel Charts.
The fitting of a bay window trim kit does not effect the distances and reference points referred to in the diagram and chart.
Noncombustible mantels and legs may be installed at any height and width around the appliance. When
using paint or lacquer to finish the mantel, such paint or lacquer must be heat resistant to prevent discoloration.

High Elevations
Input ratings are shown in BTU per hour and are certified without deration for elevations up to 4,500 feet (1,370m) above sea level.
For elevations above 4,500 feet (1,370m) in USA, installations must be in accordance with the current ANSI Z223.1/NFPA 54 and/or local codes having jurisdiction.
In Canada, please consult provincial and/or local authorities having jurisdiction for installations at elevations above 4,500 feet (1,370m).
Gas Line Installation
When purging the gas lines, the front window frame assembly must be removed.
The gas pipeline can be brought in through the rear of the appliance as well as the bottom. Knockouts are
provided on the bottom behind the valve to allow for the gas pipe installation and testing of any gas connection. It is most convenient to bring the gas line in from the rear right side of the valve as this allows fan installation or removal without disconnecting the gas line.

XDV Direct Vent Gas Fireplace
The gas line connection can be made with properly tinned 3/8” copper tubing, 3/8” rigid pipe or an approved flex connector. Since some municipalities have additional local codes, it is always best to consult your local authority and the National Fuel Gas Code, ANSI Z223.1/NFPA 54 in the USA or the CSA-B149.1 installation code.

Fig. 6 Typical gas supply installation.
Always check for gas leaks with a mild soap and water solution applied with a brush no larger than 1” (25 mm). Never
apply soap and water solution with a spray bottle. Do not use an open flame for leak testing.
The fireplace valve must not be subjected to any test pressures exceeding 1/2 psi.
Isolate or disconnect this or any other gas appliance control form the gas line when pressure testing.
The gas control is equipped with a captured screw type pressure test point, therefore it is not necessary to provide a 1/8” test point up stream of the control.
When using copper or flex connector use only approved fittings. Always provide a union when using black iron pipe so the gas line can be easily disconnected for burner or fan servicing. See gas specification for pressure details and ratings.
The fireplace valve must not be subjected to any test pressures exceeding 1/2 psi. Isolate or disconnect this and any other gas appliance control from the gas line when pressure testing.
Remote ON/OFF Switch
Do not wire the remote ON/OFF wall switch for this gas appliance into a 120v power supply.
1.Thread wire through the electrical knockout located on either side of the unit. Take care not to cut the wire or insulation on metal edges. Ensure the wire is secured and protected form possible damage. Run one end of the gas control valve and the other end to the conveniently located wall switch.
2.Attach the wire to the ON/OFF switch and install switch into receptacle box. Attach cover plate to switch.
3.Connect wiring to gas valve. (Fig. 7)

EB-1 Electrical Box
The fireplace, when installed, must be electrically connected and grounded in accordance with local codes or, in the absence of local codes, with the current CSA C22.1 Canadian Electrical Code.
For USA installations follow local codes and the national electrical code ANSI/ NFPA No. 70.
It is strongly suggested that the wiring of the EB-1 Electrical Junction Box be carried out by a licensed electrician.
Ensure that the power to the supply line has been disconnected before commencing this procedure.

General Information Assembling Vent Pipes
Canadian Installations:
Venting system must be installed in accordance with the current CSA-B149.1 installation code.
USA Installations:
The venting system must conform with local codes and/ or the current National Fuel Gas code ANSI Z223.1/ NFPA 54.
Only venting components manufactured by CFM Corporation can be used in Direct Vent systems.
Flex Vent Pipes
Before joining the flex vent pipe to the unit, apply a bead of high temperature sealant* (provided) to the 4” pipe exiting the fireplace. Secure flex vent piep in place with a hose clamp (provided).
*Be sure the flex pipe overlaps at least 1” (25 mm) onto the collars of the fireplace and termination. If the termination has an internal bead, be sure to overlap and secure 1” (25 mm) past the bead.
* Be sure the flex vent is flat and flush with the flue or outer collar before proceeding. Apply a tug to be sure the vent will not slip off the collars.
Repeat process with 7” flex vent pipe. The same procedure must be performed on the vent side.

Twist Lock Pipes
When using CFM Corporation twist-lock pipe it is not necessary to use sealant on the joints. The only areas of the venting system that need to be sealed with high temperature silicone sealant are the sliding joints of any telescopic vent section used in the system.
To join the twist lock pipes together, simply align the beads of the male end with the grooves of the female end, then while bringing the pipe together, twist the pipe until the flange on the female end contacts the external flange on the male end. It is recommended that you secure the joints with three (3) sheet metal screws, however this is not mandatory with twist lock pipe.
To make it easier to assemble the joints we suggest putting a lubricant (Vaseline or similar) on the male end of the twist lock pipe prior to assembly.

How to Use the Vent Graph
The vent chart should be read in conjunction with the following vent installation instructions to determine the relationship of the vertical and horizontal dimensions of the vent system.
1.Determine the height of the center of the horizontal vent pipe exiting through the outer wall. Using this dimension on the Sidewall Vent Graph (Fig. 20) locate the point intersecting with slanted graph line.
2.From the point of this intersection, draw a vertical line to the bottom of the graph.
3.Select the indicated dimension, and position the fireplace in accordance with same.
Example A:
If the vertical dimension from the floor of the fireplace is 11’ (3.4 m) the horizontal run to the face of the outer wall must not exceed 14’ (4.3 m).
Example B:
If the vertical dimension from the floor of the unit is 7’ (2.14 m), the horizontal run to the face of the outer wall must not exceed 8¹⁄’ (2.6 m).

Rear Wall Installation
Twist Lock Pipe
STEP 1
Locate vent opening on the wall. To locate hole center consult with appropriate fireplace dimensions, Page 4. Frame as shown below.
NOTE: When using flex vent, the opening will have to be measured according to the 1/2” (13 mm) rise in 12” (305 mm) vertical run.
Combustible Walls (Fig. 23): Cut a 10³⁄ ”H x 9³⁄ ” W (264 x 240 mm) hole through the exterior wall and frame as shown.
Noncombustible Walls (Fig. 23): Hole opening must be 7¹⁄ ” (190 mm) in diameter.
Zero clearance sleeve is only required for combustible walls.
STEP 2
Measure wall thickness and cut zero clearance sleeve parts to proper length (MAXIMUM 12”/305 mm). Assemble sleeve and attach to firestop with #8 sheet metal screws (supplied). (Fig. 24)
STEP 3
Measure the horizontal length requirement for the venting including a 2” (51 mm) overlap, i.e. from the elbow to the outside wall face plus 2” (51 mm). (Fig. 22)

STEP 4
Install the 4” (102 mm) vent to the appliance collar and secure with three (3) sheet metal screws. Install the 7” (178 mm) vent pipe tot he appliance collar and secure with three (3) sheet metal screws. It is not necessary to seal this connection. If a 45° elbow is being used, attach the elbow to the appliance in the same manner then attach the venting to the elbow.
It is critical there is no downward slope away from the appliance when connecting
the vent or elbow.
STEP 5
Guide the venting through the vent hole a you place the appliance in its installed position. Guide the 4” (102 mm) and 7” (178 mm) collar of the vent termination into the outer ends of the venting. Do not force the termination. If the vent pipes do not align with the termination, remove and realign the venting at the appliance flue collars. (Fig. 25) Attach the termination to the wall as outlined in the instruction sheet supplied with the termination.

FP1472
Fig. 27 There must be a 1/2” rise per foot length.
Vertical Sidewall Applications
Since it is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to.
The Vent Graph shows the relationship between vertical and horizontal side wall venting and will help to determine the various dimensions allowable.
Minimum clearance between vent pipes and combustible materials is 1”(25 mm) on top, bottom and sides unless otherwise noted.
When vent termination exits through foundations less than 20” below siding outcrop, the vent pipe must flush up with the siding. It is always best to locate the fireplace in such a way that minimizes the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent pipe from the flue collar of the fireplace to the face of the outer wall.
Horizontal plane means no vertical rise exists on this portion of the vent assembly.
When installing the appliance as a rear vent unit, the 90° or 45° transition elbow attached directly to the rear of the unit is NOT INCLUDED in the following criteria and calculations, and unless specifically mentioned should be ignored when calculating venting layouts.
16 |
10009383 |
•The maximum number of 90° elbows per side wall installation is three (3). (Fig. 28)
•If a 90° elbow is fitted directly on top of the fireplace flange, the maximum horizontal vent run before the termination or a vertical rise is 36” (914 mm). (Fig. 29)

•If a 90° elbow is used in the horizontal vent run (level height maintained) the maximum horizontal vent length is reduced by 36” (914 mm). (Fig. 29) This does not apply if the 90° elbows are used to increase or redirect a vertical rise. (Fig. 30, 31)
Example: According to the vent graph (Page 15) the maximum horizontal vent length in a system with a 7.5’ (2.3 m) vertical rise is 20’ (6 m) and if a 90° elbow is required in the horizontal vent it must be reduced to 17’ (5.2 m). In Figure 31 Dimension A plus B must not be greater than 17’ (5.2 m).

•The maximum number of 45° elbows permitted per side wall installation is two (2). These elbows can be installed in either the vertical or horizontal run.
•For each 45° elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 18” (45 cm). This does not apply if the 45° elbows are installed on the vertical part of the vent system.
•The maximum number of elbow degrees in a system is 270°. (Fig. 32)
