Granule pack installation
The granules as well as being added to create a more realistic log flame effect (by
diffusing the gas flames through the burner ports) also assist in soot prevention and
are CRITICAL to the performance of the heater.
Never pour the granules directly from the pack as dust particles from the plastic bag
may block the ports.
NG installations
Place the granules evenly across the burner—use the whole pack.
ULPG installations
Carefully place 30 of the granules as close as possible to the front burner ports as shown on
the diagram below. DO NOT cover any of the front right side ports. It's important this is done
correctly as incorrect placement can cause high yellow flames (dirty combustion) that may
cause sooting.
It is desirable that the flames touch the granules as this diffuses any 'candling' effect and
enhances the realistic log burning look of the heater.
