1. Check ignition, pilot stability, burner flames, and the full range of
movement of the flame adjustment knob. See owner's lighting
instructions further on in this manual for full details, see fig 28.
2. Aeration adjustment
As described in section 17, burner aeration is adjustable. For the vast
majority of installations, no adjustment will be necessary. However, in a
very few instances, performance may be improved by adjusting the
aeration by sliding the shutter (See figure 4 page 8). Evaluate the aeration
only after the unit has warmed up – approximately 15 minutes.
The shutter setting is very sensitive. Small adjustments can make a
substantial difference to the flames
Increasing aeration will cause the flame to appear more transparent and
blue making the ceramic fuel effects glow more.
Decreasing aeration will cause the flames to appear more yellow or orange making the fuel effects glow less. Too little
aeration may result in black carbon forming and dropping into the firebox.
3. Check venting efficiency
3.1 A check for correct venting of combustion products must be made before the installed appliance is left with the
customer.
You will need a mirror for this check.
3.2 The mirror must be cold and dry for the check so keep in a cool place such as a freezer compartment.y while the fire is
warming up.
3.4 Open the gas valve.
3.5 Light the appliance and set to high heat.Leave the appliance on for five minutes.
3.6 Make sure that the mirror is cold and dry. Place the mirror face downwards touching the bottom front of the black cross
member and angled slightly upwards so that the mirror face can be seen.(see fig 29)
3.7 The mirror face should remain clear for at least 5 seconds.
If condensation appears over the mirror face within 5 seconds the venting is not functioning properly. Don't allow the
appliance to be used until the problem is cured.
