Final Finishing

Noncombustible materials such as brick or tile can be extended over the edges of the face of the fireplace. Do

not cover the window frame assembly, any vent, louvre assembly top or louvre assembly bottom. If a

Trim Kit is to be installed, brick and tile will have to be installed flush with the side of this appliance.

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 gas line the front glass must be removed.

The gas pipeline can be brought in through the right side of the appliance. Knockouts are provided at convenient locations to allow for the gas pipe installation and testing of any gas connection.

The gas line connection can be made with properly tinned 3/8" copper tubing, 1/2" 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 CSA-B149.1 installation codes.

For USA installations consult the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.

FP297a

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” (25mm). 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 from 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 that the gas line can be easily disconnected for burner or fan servicing. (Fig. 6) See the gas specifications for pressure details and ratings.

General Information Assembling Vent Pipes

Canadian Installations

The venting system must be installed in accordance with the current CSA-B149.1 installation code.

USA Installations

The venting system must conform to local codes and/or the current National Fuel Code ANSI Z223.1/NFPA 54.

Only venting components manufactured by CFM Corporation may 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” (25mm) onto the collars of the fireplace and termination. If the termination has an internal bead, be sure to overlap and secure 1” (25mm) past the bead.

* Be sure the venint is actually crushed 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

DVRT41Direct Vent Gas Fireplace

When using 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 collars on the fireplace and termination, and the sliding joint of any telescopic vent section used in the system.

To join twist lock pipes together, simply align the beads of the male end with the grooves of the female end, twisting the pipe until the flange on the female end contacts 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. (Fig. 17)

To make it easier to assembly 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 Graph should be read in conjunction with the following vent installation instructions to determine the relationship between the vertical and horizontal dimensions fo 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. 17), locate the point intersecting with the 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 unit is 11’ (3.4m) the horizontal run to the face of the outer wall must not exceed 14’ (4.3m).

EXAMPLE B:

If the vertical dimension from the floor of the unit is 7’ (2.1m), the horizontal run to the face of the outer wall must not exceed 8¹⁄₂’ (2.6m).

Rear Wall Vent Installation

Step 1

Locate and cut the vent opening in the wall. For combustible walls first frame in opening. (Fig. 21)

NOTE: When using flex vent, the opening will have to be measured according to the 1/2” (13mm) rise in 12” (305mm) vertical run.

Combustible Walls: Cut a 10³⁄₈”H x 9³⁄₈” W (265mm x 240mm) hole through the exterior wall and frame as shown. (Fig. 21)

Noncombustible Walls: Hole opening should be 7¹⁄₂” (191mm) 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” / 305mm). Assemble sleeve to its maximum opening (10³⁄₈” x 9³₈”) and attach to firestop assembly. (Fig. 22)

Step 3

Measure the horizontal length requirement for the venting including a 2” (51mm) overlap, i.e. from the elbow to the outside wall face plus 2” (51mm). (Fig. 20)

Step 4

Install the 4” (102mm) vent to the appliance collar and secure with 3 sheet metal screws. Install the 7” (178mm) vent pipe to the appliance collar and secure with 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 that there is no downward slope away from the appliance when connecting the vent or elbow.

Step 5

Guide the venting through the vent hole as you place the appliance in its installed position. Guide the 4” (102mm) and 7” (178mm) 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. 23) Attach the termination to the wall as outlined in the instruction sheet supplied with the termination.

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, showing the relationship between vertical and horizontal side wall venting, will help to determine the various dimensions allowable.

Minimum clearance between vent pipes and combustible materials is 1” (25mm) on top, bottom and sides unless otherwise noted.

When vent termination exits through foundations less than 20” (508mm) below siding outcrop, the vent pipe must flush up with the siding.

It is 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 (or the top of the Transition Elbow) 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.

NOTE: There must be a 1/2” (13mm) rise in a 12”

(305mm) length of flex vent.

Step 4

Assemble the flex vent to the collars on the termination as you did on the appliance.

Step 7

Apply high temperature sealant to 4” (102mm) and 7” (178mm) collars or the termination one inch away from crimped end. Guide the vent terminations 4” and 7” collard into their respective vent pipes. Double check that the vent pipes overlap the collars by 2” (51mm). Secure the termination to the wall with screws provided and caulk around the wall plate to weatherproof. As an alternative to screwing the termination directly to the wall, you may also use expanding plugs or an approved exterior construction adhesive. You may also attach the termination with screws through the inner body into the 4” vent pipe, however for this method, you must extend the 4” pipe approximately 6” (152mm) beyond the outer face of the wall.

Support horizontal pipes every 36” (914mm) with metal pipe straps.

Step 5

Slide the 7” (178mm) flex vent pipe over the 4” flex vent pipe and secure the 7” collar as described on Page 12.

Step 6

Bend the flex pipe horizontal so the bottom of the horizontal pipe measure 6¹⁄₂” (165mm) from the top of the unit immediately after the 90° formation. (Fig. 36) Be sure to follow the 1/2” (13mm) rise in a 12” (305mm) horizontal run rule.

Step 7

Install the 4” flex then 7” flex to the termination.

NOTE: The 40” (1016mm) flex vent is used for 90° off the top of the unit then out the back wall.

Follow Step 1 and 2 on Page 17.

Step 3

Install the four (4) spacer springs on the 4” flex vent pipe. When installing the spacer springs around the 4” pipe, stretch the spring to approximately 15” (381mm), wrap the spring around the pipe and interlock the ends of the spacer spring approximately 2” (51mm). Measure 6³⁄₄” (172mm) from the end of the pipe. Place the

Below Grade Installation

When it is not possible to meet the required vent terminal clearances of 12” (305mm) above grade level, a snorkel kit is recommended. It allows installation depth down to 7” (178mm) below grade level. The 7” (178mm) is measured from the center of the horizontal vent pipe as it penetrates through the wall.

Ensure the sidewall venting clearances are observed. If venting system is installed below ground, we recommend a window well with adequate and proper drainage to be installed around the termination area.

If installing a snorkel, a minimum 24” (610mm) vertical rise is necessary. The maximum horizontal run with the 24” vertical pipe is 36” (914mm). This measurement is taken from the collar of the fireplace (or transition elbow) to the face of the exterior wall. See the Sidewall Venting Graph for extended horizontal run if the vertical exceeds 24” (610mm).

1. Establish vent hole through the wall (Fig. 31)

2. Remove soil to a depth of approximately 16” (406mm) below base of snorkel. Install drain pipe. Install window well (not supplied). Refill hole with 12” (305mm) of coarse gravel leaving a clearance of approximately 4” (102mm) below snorkel. (Fig. 37)

3. Install vent system.

4. Ensure a watertight seal is made around the vent pipe coming through the wall.

5. Apply high temperature sealant caulking (supplied) around the 4” and 7” snorkel collars.

6. Slide the snorkel into the vent pipes and secure to the wall.

7. Level the soil so as to maintain a 4” (102mm) clearance below snorkel. (Fig. 37)

• Vertical installations up to 40’ (12m) in height. Up to

a 10’ (3m) horizontal vent run can be installed within the vent system using a maximum of two 90° elbows. (Fig. 39)

• Up to two 45° elbows may be used within the

horizontal run. For each 45° elbow used on the horizontal plane, the maximum horizontal length must be reduced by 18” (450mm).

Example: Maximum horizontal length:

No elbows = 10’ (3m) 1 x 45° elbow = 8.5’ (2.6m) 2 x 45° elbows = 7’ (2.1m)

• A minimum of an 8’ (2.5m) vertical rise is required.

• Two sets of 45° elbow offsets may be used within

the vertical sections. From 0 to a maximum of 8’ (2.5m) of vent pipe can be used between elbows. (Fig. 40)

• 7DVCS supports offsets. (Fig. 42) This application

will require that you first determine the roof pitch and use the appropriate starter kit. (Refer to Venting Components List)

• The maximum angular variation allowed in the

system is 270°. (Fig. 40)

• The minimum height of the vent above the highest

point of penetration through the roof is 2’ (610mm). (Fig. 43) Refer to note 2, Page 13.

Glass Cleaning

It is necessary to clean the glass periodically. During start-up condensation, which is normal, forms on the inside of the glass and causes lint, dust and other airborne particles to cling to the glass surface. Also initial paint curing may deposit a slight film on the glass. It is therefore recommended the glass be cleaned two or three times with a non-ammonia household cleaner and warm water (gas fireplace glass cleaner is recommended). After the initial cleaning process the glass should be cleaned two or three times during each operating season depending on the environment in the house.

Clean the glass after the first two weeks of operation. Do not clean glass when hot. Do not use abrasive cleaners. Do not strike or slam the glass.

If an Error Code 3 is observed while performing the testing, complete the following:

1. Make sure the spade connectors are pushed all the way on. If the Error Code 3 is still showing, then go to the next step.

2. Switch the front two thermopile leads with the back two. Be sure the white lead is connected to the spade with the white dot next to it. If the Error Code 3 is still showing, replace the thermopiles.

If an Error Code 8 is observed while performing the testing, complete the following:

1. Confirm the valve is not in REMOTE mode.

• If the valve is producing Error Code 8 and in

REMOTE mode, the valve is defective and should be replaced.

• If the valve is in LOCAL mode and producing

Error Code 8, then go to the next step.

Maintenance

Burner and Burner Compartment

It is important to keep the burner and the burner compartment clean. At least once per year the logs and lava rock/ember material should be removed and the burner compartment vacuumed and wiped out. Remove and replace the logs as per the instructions in this manual.

Always handle the logs with care as they are fragile and may also be hot if the fireplace has been in use.

FK24/FK12 Fan Assembly

The fan unit requires periodic cleaning. At least once per month in the operating season, open the lower louvre panels and wipe or vacuum the area around the fan to remove any build up of dust or lint.

Brass Trim

Clean the brass trim pieces using a soft cloth lightly dampened with lemon oil. Do not use water or household cleaners on any brass components.

Contact your local representative to arrange an annual service program.

Cleaning the Standing

Pilot Control System

The burner and control system consists of

• burner tube • gas orifice

• pilot assembly • thermopile

• millivolt gas valve

Most of these components may require only an occasional checkup and cleaning and some may require adjustment. If repair is necessary, it should be

performed by a qualified technician.

To obtain proper operation, it is imperative that the pilot and burner’s flame characteristics are steady, not lifting or floating.

Typically, the top 3/8” or 1/2” of the thermopile should be engulfed in the pilot flame. (Fig. 71)

To adjust pilot burner; (by qualified service technician)

1. Remove pilot adjustment cap.

2. Adjust pilot screw to provide properly sized flame.

3. Replace pilot adjustment cap. The primary air shutter is set at factory and should only

be adjusted, if necessary, by a qualified service technician.
