INSTALLATION EMBER AND PAN MATERIAL PLACEMENT Continued 1. Open the bag(s) of vermiculite and fill the entire burner pan until the burner tube is completely covered (see Figure 20). 2. Smooth the pan material just even with edges of the burner pan. 3. Remove the ember material from the bag and flatten small amounts into quarter size pieces and lay on top of the surface of the pan material (see Figure 21). 4.
INSTALLATION Continued Grate 0.5" Pan and Ember Material NOTICE: Do not put lava rock inside the burner pan or around the air mixer fitting. Placing lava rock inside the burner pan or blocking the openings of the propane/LP air-mixer could cause performance problems.

INSTALLATION Continued 6. Repeat the process for the opposite door assembly. 7. To adjust the doors, slide them partially open. Using a screwdriver, loosen the hold-down screws in the spring clip (see Figure 34) and pivot plate. 8. Close both doors until evenly joined at the middle and note the gap at the outer edges of the face. 9. Reopen one door at a time and retighten the upper and lower hold-down screws. 10. Repeat the process until both doors are evenly joined, spaced and working freely.
OPERATING FIREPLACE FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
OPERATING FIREPLACE INSPECTING BURNERS Continued Check pilot flame pattern and burner flame patterns often. TO TURN OFF GAS TO APPLIANCE PILOT ASSEMBLY 1. Turn off the wall switch. 2. Turn off all electric power to the appliance if service is to be performed. 3. Fully open glass doors if installed. 4. Remove front hearth brick and control access panel. 5. Turn gas control knob clockwise to “OFF”. Do not force. 6. Replace front refractory brick access panel. 7. Fully close glass doors if installed.
CLEANING AND MAINTENANCE WARNING: Installation and repair should be done by a qualified service person. The appliance should be inspected before each use and at least annually by a qualified service person. More frequent cleaning may be required due to excessive lint from carpeting, bedding material, pet hair, etc. It is imperative that the control compartments, burners and circulating air system be kept clean. WARNING: The logs can be hot. Handle only when cool.
