OPERATION CHECKS
1. Check ignition, pilot stability , burner flames and the full range of the thermostat using the rotary switch inside the
appliance and all other controls (appliance rocker switch, wall switch, remote hand unit). See owner’s lighting instructions
further on in this manual for full details.
2. Aeration
adjustment
As described in section 13, 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 68). 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. We strongly advise
that adjustments be made in steps o f no more than
1
/
64
” (0.4mm).
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.
