To accommodate the various configurations, we have provided access openings in the bottom of the
unit for gas line and wall switch wires. This may not be convenient for some installations, if so you may
drill an access opening into the lower face of the unit (1" for gas line, 1/2" for the grommet).
1. Route the 3/8 inch N.P.T. black iron gas line or equivalent to the fireplace. Include a manual shut-off
valve and union in the line so the control may be disconnected for servicing. A drip leg is also
recommended in the gas supply line.
2. Install a rigid black pipe or if local codes permit a 3/8 inch flex connector and shutoff valve to the gas
line and the fireplace gas valve. Seal and tighten securely. An adapter fitting is required between the
gas valve and flex connector if used. Do not kink flex connector (Figure 3).
3. Check for gas leaks with a soap and water solution. DONOT USE AN OPEN FLAME.
NOTE: PURGE ALL GAS LINES WITH THE GLASS DOOR OF THE FIREPLACE REMOVED. ASSURE THAT ACONTINUOUS GAS
FLOW IS AT THE BURNER BEFORE INSTALLING THE DOOR.

Pilot Burner Adjustment
1. Adjust the pilot screw to provide a properly sized flame.
2. Do not adjust the pilot screw all the way out counterclockwise because it will leak gas.
Flame Switch
(For Units with 6CN and 6CLP Controls)
Your fireplace has been equipped with a thermocouple
which senses the flame and shuts of the gas flow to the
pilot and main burner in the event that the pilot flame is
unstable or becomes extinguished.
DANGER: BYPASSING THE THERMOCUPLE MAY LEAD TO AN EXPLOSION
WHICH COULD RESULT IN PERSONAL INJURY.
Do NOT alter the wiring of the control. Replace the thermo-
couple only with components approved by the manufacturer.
Venturi Adjustment
Natural gas models have a closed shutter. Opening the air
shutter will cause a more blue flame, but can cause flame
lifting from the burner ports. Propane gas models have an
air shutter set at
3/16 (.188) inch open. The same conditions as above apply
for propane gas.
NOTE: AIR SHUTTER AJUSTMENT MUST ONLY BE DONE BY AQUALIFIED
GAS INSTALLER.

Maintenance of the Appliance
Air flowing through the appliance will cause dust and lint to collect on the grate, burner and logs. Exessive
buildup of dust and lint can cause the pilot and burner to operate improperly and produce hazardous
levels of carbon monoxide, a poisonous gas. The appliance may produce carbon (soot) during operation.
This carbon (soot) may collect on some logs, some areas of the grate and on the fireplace and vent.
Slight carbon buildup is acceptable.
The following is a recommended monthly maintenance program:
1. Turn the gas OFF at the line cut-off valve and allow the appliance to cool.
2. Blow or vacuum all dust and lint out of the appliance, paying particular attention to the pilot, air shutter
end of the burner, air passage into and through the appliance and control.
3. Vacuum or brush away all dust, carbon or lint on the logs and grate.
4. Turn the gas ON at the line cut-off valve and light the appliance according to the isntructions on the
chain.
5. Check all piping, pilot tubing, and manifold connections for leaks with a soap and water or liquid leak
detecting solution. If any leaks are observed, turn the gas OFF immediately and make the necessary
repairs.
6. Light the pilot and visually inspect the flame appearance. Note: Any maintenance of the appliance
that requires disconnection of the appliance from the gas line or removal of the control, burner or pilot
should only be performed by a qualified person.

COMBUSTION AIR PRECAUTIONS
NOTE: The use of outside air for combustion is optional unless required by building codes. It is only necessary to
supply outside combustion air to one side of the fireplace. Use the model OAC4 combustion air kit.
1. Extremely long runs and numerous turns in the duct leading from the fireplace to the combustion air assembly
should be avoided. These conditions will increase the resistance to the free flow of air through the duct. Refer
to Figure 9 for methods of installing the outside air for combustion assemblies.
2. The combustion air assembly should be located at an exterior location, which is not likely to be accidentally
blocked in any manner. The assembly should be located above the snow line to prevent blockage by snow
accumulation.
3. The combustion air inlet assembly should never be mounted in a garage or storage area where combustible
fumes such as gasoline might be drawn into the fireplace.
4. Combustion air can be drawn from the crawl space under a house when an adequate supply of air is provided
by open ventilation.
5. Do not take combustion air from attic space or garage space.

COMBUSTION AIR ASSEMBLY 16
MODEL AK4 COMBUSTION AIR ASSEMBLY
1. Remove the cover plate from the 4-inch outlet opening location on the left outside of the fireplace. DO NOT
remove the cover if the outside air will not be connected.
2. Place the starting collar (4 inch) into the hole on the left side of the fireplace. Fasten it in place with the four
sheet metal screws provided.
3. Cut a 6-inch diameter opening for model AK4 in the outside wall covering where the outside vent is to be
located.
4. Select and cut a piece of duct sufficient length to attach to the fireplace and protrude at least three inches
beyond the face of the wall to which the inlet air vent will be attached. The duct may be cut with a standard
pocket knife (use FP-4 U duct for maximum efficiency and safety). Do not use a combustible duct. Always
use UL Listed Class 0 or 1 duct material. If it is necessary to splice the duct, a Model 403 duct connector
should be used to splice duct sections.
5. If the duct is the insulated type, push the insulation back from one end of the duct approximately two inches.
6. Slip the exposed end of the duct over the starting collar on the fireplace.
7. Using the sheet metal screws or duct clamps, secure the duct to the starting collar and to the outside vent.
8. Nail or screw the outside vent to the surface of the wall.
