Refuelling technique is important for good performance. The best efficiency and performance
from your insert can be achieved by adding partial loads of fuel and allowing them to get up to
operating temperature before adding additional fuel. Adding a large amount of fuel at one time
will increase the time required to get the fuel up to its ignition temperature, and an extended time
to reach optimal performance. When refuelling, open the air control or hold the door partially
open 1” (25 mm) or less, long enough (less than 5 minutes) so that the fire has well-established
flames. When refuelling, care is required to ensure that fuel or embers do not fall out of the door
opening.
3.6 Blower operation
Allow the insert to heat up to operating temperature before turning on the blower. Increased
airflow from the blower will remove heat and affect the combustion efficiency during start-up.
For this reason we equipped the blower assembly with a heat sensor which will activate the
blower at the selected speed. The 3 position rocker switch is to control the blower speed « Low
towards the bottom – Off in the middle – Hi towards the top », « Low » being the minimum air
flow, « Off » to stop air circulation and « Hi » being the maximum air flow. If you prefer to
control the blower manually and at any time you will need to bypass the heat sensor. The heat
sensor is bypassed when the 2 position rocker switch is set to OFF.
The blower should be kept clean and dust free. Life of the blower will be shortened if operated
in a dust filled environment, or if the blower is overheated by restricting air supply. Stalling the
motor, or over firing the insert with the blower turned off will also damage the blower. The
blower must not be over heated.
