Operation Checks - Valor PORTRAIT 922ECN Installation & Operating Instructions Manual

Final Checks
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.
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 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.
Check venting efficiency
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 fire is warming up.
1. Open the gas valve.
2. Light the appliance and set to high heat. Leave the
appliance on for five minutes.
3. 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.
4. The mirror face should remain clear for at least 5
seconds.
5. 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.
