13. OPERATION CHECKS
Burner operation
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.
Aeration adjustment
As described in section 11, 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 20). 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 logs glow more.
Decreasing aeration will cause the flames to appear more yellow or orange making the logs glow less.
Too little aeration may result in black carbon forming and dropping into the firebox.
