9.Place logs “B” as shown in Figure 45. Lift the end of log “A” that will be propped up and place log “B” under it. At the same time, the other side of log “B” is placed over the other log “A”. Repeat procedure for the other log “B”.

10.Take twigs “C” (shaped like a “Y”) and place them as shown in Figure 46.

11.Take twigs “D” (bent twig) and place them as shown in Figure 46.

12.Place twig “E” across the top of logs “B” a shown in Figure 46.

13.When finished installing the logs, close the glass doors while making certain that the safety door switch is fully depressed by the door frame before securing the four (4) spring loaded latches.

14.Replace the louvers in reverse order with the grilles pointing in the down position.

IMPORTANT:Louvered openings must not be obstructed, and upper and lower panels must remain removable for servicing. Use only heat-resistant, noncombustible mortar or adhesive when securing facing material.

Note: Combustible material, such as wood, that has been fireproofed is not considered noncombustible.

PILOT ASSEMBLY

ADJUSTMENT

The pilot assembly is factory preset for the proper flame height. Alteration to these settings may have occurred during shipping and handling. If this is the case, some minor adjustment may be neces- sary and should be done by a qualified technician. To access the pilot assembly, the glass door must be opened. The proper settings for the thermopile height should be at a distance of 3/8" (.95cm) to 1/2" (1.3cm) from the pilot flame as shown in Figure 47.

BURNER FLAME ADJUSTMENT

The air shutter, located at the underside of the main burner (see Figure 48), has been factory preset to the proper air-to-gas ratio which results in an even, clean burning flame across the burner (see Figure 49). If readjustment is necessary, you can restore the proper air-to-gas ratio by loosening the air shutter screw and rotating the air shutter until the proper flame setting is achieved (the shutter's normal setting is “full opened”. Do not forget to retighten the air shutter screws.
