2- The burner / pan assembly is shipped ready for right-hand gas connection. NOTE- If an 18” log set is being installed
with a safety pilot kit, if left-hand gas supply connection is necessary, or if unit must be converted for use with propane gas, follow the steps outlined in the sections which begin on page 3 and then continue with step
3.
3– Remove the existing cap or gas jet assembly from the gas stub in your fireplace. Clean the threads using either a wire brush or steel wool. Apply Teflon tape or pipe dope to the steel fitting and attach the provided brass adaptor to the stub. 4– Place the burner / pan assembly in the fireplace. The pan should be centered both front to back and side to side.
IMPORTANT
If this decorative gas log set is to be used in a pro­pane application, complete changeover procedures as outlined in changeover kit instructions before continuing.
Burner. Once burner or pilot has been lit, use a soap solution to check the gas connection before proceeding. Apply soapy water to each connection and watch for bubbles. If bubbles are seen, turn off the gas, retighten the connection, relight the burner or pilot and recheck for tightness. DO NOT use a lighted match or other source of ignition to check for leaks. Repeat this proce­dure until you are sure that there are not leaks in the gas connections.
IMPORTANT
If your system includes a safety pilot, cover the pilot assembly to protect it before installing sand and embers.
WARNING
Provided sand must not be used in propane gas ap­plications. Vermiculite mixture provided with pro­pane changeover kit must be used in place of sand.
5- Bend the provided gas connector to facilitate its installation between the burner and the gas stub. BE CAREFUL! The connector is easily kinked if it is bent too sharply. Attach one end of the gas connector to the brass elbow or safety pilot fitting. Attach the other end to the brass adaptor at the gas stub. NOTE– Brass-to-Brass connections do not
require pipe dope or Teflon tape to ensure tightness. Follow the procedures outlined in the
operation section on page 5 to light the pilot or
6- Pour the provided sand (Natural Gas) or Vermiculite (Propane Gas) into the burner pan. The sand should follow the slope of the pan, covering it and the burner tube completely. Allow the sand to spill out the front of the pan and over the sides onto the fireplace floor. Tear or cut the ember material into smaller pieced to make it look more realistic and spread the ember material evenly over the sand (or vermiculite).
REMOVE THE PROTECTIVE COVERING FROM THE SAFETY PILOT ASSEMBLY.

WARNING
The sand/ember mixture can be stacked up to the bottom of the grate in natural gas applications; how­ever, this is not the case in propane applications. The Vermiculite/ember combination should not be stacked more than 1/2” above the height of the burner pan in propane applications. Again, the sand provided with the hearth kit is NOT to be used in propane applications. The Vermiculite provided with the gas changeover kit must be used instead.
7– Center the grate over the burner pan and set it in place as shown in figure 3. The burner pan should be centered left-to-right between the front legs and the grate. The front legs of the grate should be even with front edge of the burner pan.
8- Install the two grate steps on the back of the grate as shown in figure 3.
11– Arrange the top logs on top of the base logs. This arrangement is left up to personal preference entirely. You may have to repeat this exercise several times be­fore deciding on your personal favorite. Refer to figure
4.
12– Spread the black cinder material evenly around the edge of the pan on the floor of the fireplace. If possible use the cinder material to cover the aluminum gas con­nector. Again, DO NOT cover any part of the safety
pilot assembly.
FIGURE 3
9- Carefully remove the two base logs from the box. Place the longer of the two base logs in the front of the grate. The shorter base log should be placed across the elevated grate steps.
10– Light the burner as outlined in the operation section. Allow the flame pattern to stabilize. You may have to adjust the grate placement to achieve the desired flame patter around the logs. If you move the burner/pan as­sembly, be careful not to disturb the gas connections. When you are satisfied with the flame pattern, shut off the gas and continue with the next step.
