SELECTING LOCATION

To determine the safest and most efficient location for your appliance, you must take into consideration the following guidelines:

1. The location must allow for proper clearances (see Clear- ances, page 6).

2. Consider a location where heat output would not be affected by drafts, air conditioning ducts, windows, or doors.

3. A location that avoids the cutting of joists or roof rafters will make installation easier. Figure 2 shows a plan view of a few common locations.

Flush installations are recommended where living space is limited

or at a premium, and since the space required to enclose the appliance would be located beyond an outside wall, this would also reduce the cutting of joists, roof rafters, and such. Check local codes for any restrictions.

Projected installations can extend any distance into the room. A

projection may be ideal for a new addition on an existing, finished wall.

Corner installations make use of space that may not normally be

used and provides a wider and more efficient range for radiant heat transference.

Internal wall installations provide a discreet option for room sepa-

ration and can also be ideal as an addition to an existing wall.

VENTING INSTALLATION

A B-type venting system must be connected to the appliance for venting to the outside of the building.

The following section is provided as a guide to a standard B-type vent installation.

Standing codes requirements concerning B-type vent installations may vary within your state, province or local codes jurisdiction. Therefore, it is recommended that you check with your local building codes for specific requirements or in absence of local codes, follow Section 7.0 of the current National Fuel Gas Code

NFPA No. 54/ANSI Z223.1 and in Canada with CAN/CSA B149 for Category I systems using double wall B-1 vent pipe.

This gas appliance must be vented to the outdoors only and may not be terminated into an attic space or into a chimney flue servicing a solid-fuel burning appliance.

This appliance may be vented through a manufactured chimney system or a masonry chimney using a B-vent adapter or a chimney liner system if all are listed, inspected and approved by local codes and/or building authorities.

The examples shown in Figure 10 are typical of most B-vent installations and codes practices.

Example 1:

Shows the minimum allowable system height and

lateral offset for a 60° degree or greater inclination. Code specifies that offsets at 60° degrees or greater are considered horizontal and must follow the 75% percent rule for lateral to total vertical system height. Codes also allows only one offset in the total system when at 60° degrees or greater. The total vertical height in this example represents the minimum height of 8 feet and therefore the allowable lateral is 6 feet when the 75% percent rule applies. If the lateral length must exceed 75% then the system must be sized in accordance with the Category I venting tables.

Example 2:

Shows a multiple offset each at 45° degrees of

inclination. Multiple offsets are permitted if they do not exceed 60° degrees of inclination. The total lengths of the two offsets are not required to meet the 75% percent allowable rule.

Example 3:

Shows a single offset at 45° degrees of inclination and

therefore the lateral length at 10 feet of offset does not have to meet the 75% percent rule.

In each case the offsets must be supported and firestops must be positioned wherever the vent must pass through a sub-floor, ceiling joist or an attic overhang. The vent pipe must terminate vertically into a listed type vent cap and extend a sufficient height through an approved roof flashing, roof jack or a roof thimble. At all points the listed clearances must be maintained.

VENTING INSTALLATION

Checking for Proper Venting

Vent terminations must be located in accordance with height and proximity rules of NFPA No. 54 or CAN/CSA B149. These rules apply to vents at 12 in. diameter or less and require a minimum height in accordance with the roof pitch and a minimum of 8 ft. distance from a vertical wall or obstruction (see Figure 11).

If venting horizontally through a side wall becomes necessary, a listed thimble approved for use with B-type vent must be used. Check with your local codes before venting through a side wall.

Some codes areas allow the use of existing B-type vent systems if the system is at or above the recommended diameter of the flue.

The flue connection must be made using listed B-type connectors and the existing system must be code inspected for damage and proper installation.

It is not recommended that this appliance be common vented with an existing gas burning appliance. However, if it becomes necessary to common vent this appliance, the venting system must be sized and configured in accordance with the common venting guides Appendix G of the current National Fuel Gas Code NFPA No. 54/ ANSI Z223.1 and in Canada with CAN/CSA B149.

Note:

Before connecting this appliance to an existing vent system or a common venting system consult with your local architect, planner, or building official.

WARNING: This appliance must be properly con-

nected to a system and must not be connected to a chimney flue servicing a separate solid fuel burning appliance.

CHECKING FOR PROPER VENTING

After completing and checking the electrical, gas and vent connections, follow the lighting instructions and allow the main burner to run for approximately 5 minutes. Hold a lighted match or cigarette near the top edge of the fireplace opening and play it along the entire length of the opening (see Figure 11). Proper venting should tend to draw the flame or smoke into the appliance. Improper venting or escaping of spillage of burned gas, is indicated when the match flickers or goes out. Smoke from a cigarette will also tend to disperse away from the appliance.

If the appliance is found to be improperly venting, shut it off and notify your installer or a qualified service agency to inspect the venting system.

NOTICE: This appliance is equipped with a vent safety shutoff switch which will shut down the appliance in the case of a venting problem. Do not bypass the vent safety switch. If the appliance should shut down, contact a qualified installer, service agency, or your gas supplier to have the vent inspected before operating.

Check this area along the entire top edge of the fireplace opening. Smoke or flame should be drawn into the appliance opening.

DESA recommends that a black iron gas line be routed from the gas source, through a sediment trap (shown in Figure 19), and into the appliance, Once connected through the appliance, a flexible gas line may be used for ease of installation to gas control valve (see Figure 20).

Before connecting the black iron gas line to the inside of the appliance a sediment trap must be included outside the appliance between the gas line and the gas shutoff valve. It must extend down three (3) inches beyond the center of the pipe. Prepare incoming black iron gas line with teflon tape or pipe joint compound (Check with local building codes).

CAUTION: Compounds used on threaded joints of gas piping shall be resistant to the action of Liquefied Petroleum (LP or propane), and should be applied lightly to ensure excess sealant does not enter the gas line.

WARNING: All gas piping and connections must be tested for leaks after the installation is completed.

After ensuring that the gas valve is on, apply a noncorrosive leak detection solution to all connections and joints. If bubbles appear, leaks can be detected and corrected.

Do not use an open flame for leak testing and do not operate any appliance if a leak is detected.

Complete your gas installation by connecting incoming gas line with flexible gas line. Secure tightly with wrench but DO NOT

OVERTIGHTEN.

BURNER FLAME PATTERN

Burner flames will be steady; not lifting or floating. Flames should go up through the middle of logset. Flames should not "spill" to the edges of the pan or sides of the logset.

Figure 38 shows a typical flame pattern. If burner flame pattern differs from that described:

• turn appliance off (see To Turn Off Gas to Appliance)

• see Troubleshooting, pages 19 through 21

Shutting Off Burner Only (pilot stays lit)

Turn remote control/wall switch (if installed) to the OFF position.

INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT ASSEMBLY

The pilot assembly is factory preset for the proper flame height. Alterations may have occurred during shipping and handling. The pilot is located on the back right hand side of the burner.

The height of the thermopile must be 3/8" to 1/2" above the pilot flame. The flame from the pilot burner must extend beyond the thermopile.

If your pilot assembly does not meet these requirements:

• Turn the adjustment screw marked pilot clockwise to decrease

or counterclockwise to increase the flame to proper size (see Figure 35, page 16). Do not remove the adjustment screw.

• see Troubleshooting, pages 19 through 21

TROUBLESHOOTING

Note:

For additional help, visit DESA International’s Techni-

cal Service web site at www.desatech.com.

Note:

Before troubleshooting the system, make sure the gas shutoff

valve is ON.

OBSERVED PROBLEM

Pilot will not light

Pilot will not stay lit

POSSIBLE CAUSE

1. No gas supply, or shutoff valve is OFF

2. Air in gas line

3. Construction debris clogging pilot orifice

4. Low gas pressure

5. Control valve knob is not on the PILOT position

6. Kinked pilot line

7. Bad valve

1. Loose wiring on thermopile to regulator valve. No millivolt current is being sent back to regulator

2. If valve knob and wall switch are in the ON position, probable defective regulator valve

The two most common causes of a malfunctioning gas appliance are:

1. Loose wiring connections

2. Construction debris clogging the pilot and/or gas control valve filter

REMEDY

1. Check to see if you have gas supply

2. Hold regulator control valve in the PILOT position for 2 to 3 minutes to purge air . If you smell gas stop and wait for a few minutes before trying to light the fireplace

3. Remove debris and dirt, inspect and clean any other possible obstructions

4. Contact your gas supplier

5. Refer to section on pilot lighting

6. Have a qualified technician replace pilot line

7. Replace regulator valve (see Accesso- ries, page 27)

1. Check wiring connections. Refer to wiring diagram shown in Wall Switch In- stallation, page 10

2. Have a qualified technician replace valve

No gas to burner, although wall switch and valve are set to the ON position

Frequent pilot outage

For more information, visit www.desatech.com

108660

1. Wall switch wires defective or too long

2. Thermopile not generating sufficient voltage

1. Pilot flame may be too low, causing safety pilot to “drop out”

2. Improper venting or excessive blockage

1. Check electrical connections

2. See Pilot will not stay lit, above

1. Clean and adjust pilot flame for maximum flame impingement on thermopile

2. Have the vent system inspected, including the termination cap. Remove any restriction or obstruction

TROUBLESHOOTING

Continued

OBSERVED PROBLEM

Pilot goes out when wall switch is ON

Spark ignitor will not light pilot after repeated triggering of red button

POSSIBLE CAUSE

1. Millivolt output on thermopile too high

1. Defective ignitor (no spark at electrode)

2. Defective pilot or misaligned electrode at pilot (spark at electrode)

3. No gas or low gas pressure

4. If using propane/LP gas, no propane/LP gas in tank

REMEDY

1. Replace thermopile

1. Check for spark at the electrode and pilot; if no spark and electrode wire is properly connected, replace ignitor

2. Using a match, light pilot. If pilot lights, turn off pilot and trigger the red button again. If pilot lights, an improper gas/air mixture caused the improper lighting and a longer purge period is recommended. If pilot will not light, check gap at electrode and pilot. Gap should be 1/8" to have a strong spark. If okay , replace pilot

3. A) Check remote shut off valves from

fireplace. Usually there is a valve near the fireplace and sometimes there is a valve near the main. There can be more than one (1) valve between the fireplace and main

B) Low pressure can be caused by a va-

riety of situations such as bent line, too narrow diameter of pipe, or even low line pressure. Check for kinked lines. If none, consult with plumber or gas supplier

4. Check propane/LP supply and contact local propane/LP supplier

WARRANTY INFORMATION

KEEP THIS WARRANTY

Model Serial No. Date Purchased

Always specify model and serial numbers when communicating with the factory. We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard written

warranty. We make no other warranty, expressed or implied.

LIMITED WARRANTY B-VENT FIREPLACE

DESA International warrants this product to be free from defects in materials and components for four (4) years from the date of first purchase, provided that the product has been properly installed, operated and maintained in accordance with all applicable instructions. To make a claim under this warranty the Bill of Sale or cancelled check must be presented.

This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to restore this heater to proper operating condition and an allowance for labor when provided by a DESA Authorized Service Center. Warranty part(s) MUST be obtained through authorized dealers of this product and/or DESA International who will provide original factory replacement parts. Failure to use original factory replacement parts voids this warranty. The heater MUST be installed by a qualified installer in accordance with all local codes and instructions furnished with the unit.

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation. Travel, diagnostic cost, labor, transportation and any and all such other costs related to repairing a defective heater will be the responsibility of the owner.

TO THE FULL EXTENT ALLOWED BY THE LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE PRODUCT; THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES AND LIMITS THE DURATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE TO FOUR (4) YEARS ON ALL COMPONENTS FROM THE DATE OF FIRST PURCHASE; AND DESA INTERNATIONAL’S LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT AND DESA INTERNATIONAL SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.

Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or consequential damages, so the above limitation on implied warranties, or exclusion or limitation on damages may not apply to you.

This warranty gives you specific legal rights, and you may also have other rights that vary from state to state. For information about this warranty write:
