BURNER MEDIA INSTALLATION
Step 3. Installing the Log Set and Burner Granules
DO NOT remove the burner from heater engine to
install the log set.
IMPORTANT
Use EXTREME care when handling the Log Set
components, they are made from a very fragile high
temperature material and will damage if handled
roughly. ONLY remove the components from their
packaging as required.
Note that for clarity the drawings here are displayed
without showing the entire heater.
To achieve the correct location of the log set, hold the log set (G) at
approximately 45°directly in front of the burner box (K).
Maintain this angle and place the front feet (I) of the log set behind the
unpainted inner horizontal steel lip (J) of the combustion chamber.
Take care to ensure the ends of the log set DO NOT
touch the burner box panel walls (L) during the
insertion or positioning.
IMPORTANT
To set the log set into the final position within the burner box, rotate
the back of the log set down using the location of the front feet (I) as
pivot points until it is sitting flat on the rear burner.
Confirm the correct location of the log set before proceeding with
the placement of the granular burner medium, ensuring that the log
set is firmly seated in the centre of the burner box and not touching
the side walls and that the ports of both the front and rear burners
are clean and clear of any debris that may have been shed during
the log set installation.
Installation of the granular burner medium may now begin, for best
flame effect carefully place, DO NOT POUR, the granular burner
medium over and around the front burner ports. It is desirable that
the gas jet is diffused by the granules, this will reduce any 'candling'
effect of the flame enhancing the realistic log burning look of the
heater.
DO NOT force any granular material into the burner
ports or completely block any of the burner ports.
CAUTION
DO NOT place any of the granular burner medium on
the rear burner.
Step 4. Replacing the Burner Box Glass
Replace burner box glass panel assembly in reverse sequence as
instructed in "Step 1. Removing the Burner Box Glass" on page
25.
Step 5. Completing Heater Installation
