Operation Checks
Final Checks
Check ignition, pilot stability, burner ames, and the full range of
movement of the ame adjustment knob. See owner’s lighting
instructions further on in this manual for full details.
Aeration adjustment
As described in manual, 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 page 10. 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 ames
Increasing aeration will cause the ame to appear more
transparent and blue making the ceramic fuel effects glow more.
Decreasing aeration will cause the ames 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 rebox.
Check venting efciency
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.
The mirror must be cold and dry for the check so, keep in a cool
place such as a freezer compartment while the re is warming up.
Open the gas valve.
Light the appliance and set to high heat. Leave the appliance
on for ve minutes.
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.
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.
