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 Clearances).
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 sho ws a plan view of a few common locations.
4. Do not use this appliance if any part has been under water. Immediatel y call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas con­trol that has been under water.
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 separation and can also be ideal as an addition to an existing wall.
Also, in selecting a location, the following precautions must be observed:
1. Do not connect this appliance to a chimney system used for a solid fuel burning fireplace.
2. Install in an area providing ventilation and adequate combustion air.
3. Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.
4. NEVER obstruct the front opening of the appliance or the flow of combus­tion and ventilation air. Keep control compartments accessible.
5. Do not locate in the vicinity where gasoline or other flammable liquids may be stored. The appliance area must be kept clear and free from these com­bustible materials.
6. A hearth extension is not required with this appliance. If one is installed, it is for aesthetic purposes only and does not have to meet the standard requirements.
7. If the appliance is installed on a sur­face other than wood flooring (such as carpeting, tiles, etc.) a metal or wood panel should be added, extending the full width and depth of the appliance.

VENTED TYPE DECORATIVE APPLIANCE
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 B­type 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/ANS Z223.1 and in Canada with CAN/CGA 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 9 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.

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; in this case 5".
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 Na-
tional Fuel Gas Code NFPA No. 54/ANS Z223.1 and in Canada with CAN/CGA 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 connected 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 window frame and play it along the entire length of the window (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 glass frame. Smoke or flame should be drawn into the appliance opening.

BURNER FLAME ADJUSTMENT
The main burner flame should be a blue flame somewhere between a long blue flame and a short, sharp flame that tends to blow off the ports. If flame is short, very sharp or blowing, the burner air shutter should be closed enough to obtain a long blue flame (see Figure 32). Long yellow flame produce excess carbon monoxide and could cause sooting.
TO SHUT OFF
1. For temporary shut-off, turn off remote control wall switch. Pilot burner will remain lit, ready for return to ON.
2. For long term shut-off, depress the gas valve cock v alve, located under the fire­box, turn clockwise to the OFF position.
OPERATING GUIDELINES AND MAINTENANCE INSTRUCTIONS
1. Upon completing your gas line connec­tion, a small amount of air will be in the lines. When first lighting the appli­ance it will take the appliance a few minutes to purge the air . Once pur ging is complete, the pilot and burner will light and operate as indicated in the instruction manual. Subsequent light­ing of the appliance will not require such purging.
1. When lit for the first time, the appli­ance will emit a slight odor for an hour or two. This is due to the “curing” of the logs and “burn-in” of internal paints and lubricants used in the manufactur­ing process.
2. Keep control compartment, logs burn­ers, and area surrounding the logs clean by vacuuming or brushing at least twice a year. Do not vacuum the mineral wool located in the front of the burner assembly.
3. Always turn off gas to pilot before cleaning. For example relighting, refer to the lighting instructions.
4. A qualified field service technician should inspect the appliance and venting system before use or at least annually.
WARNING: The logs can be
hot. Handle only when cool.
MAINTENANCE
WARNING: Turn off gas and electrical power before servicing appliance. It is recommended that a qualified serviceman perform these checkups at the beginning of each heating season.
In order to properly clean the burner and pilot assembly remove the logs exposing the burner and pilot assembly.
CLEANING BURNER AND PILOT
Clean all foreign materials from the top of burner and from bottom panel below. Check to make sure that burner orifice is clean. Visually inspect pilot. Brush or blow away any dust and lint accumulations. If pilot orifice is plugged, disassembly maybe re­quired to remove any foreign materials from orifice and/or tubing. When appliance is put back in service, check pilot flame patterns (see Figure 31).

OBSERVED PROBLEM
Pilot will not light
Pilot will not stay lit
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
POSSIBLE CAUSE
1. No gas supply , or shut-off 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 PILO T 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
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 18)

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. No propane/LP 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 ev en low line pressure. Check for kinked lines. If none, consult with plumber or gas supplier
4. Check propane/LP supply. You may be out of fuel
