Window Refitting & Checking
1. Refit the window with the bottom two bolts. The bolts
should be screwed in securely.
2. Refit the chain to the top right corner of the window.
3. Refit the top two bolts securing by turning them through
90°.
4. Pull the top of the window forward and release to check
that it opens slightly and returns confirming the good
function of the spring-loaded mechanism. See figure 41.
5. Similarly check the bottom of the window by pulling it
forward and releasing. See figure 41.
Operation Checks
Check ignition, pilot stability, burner flames, and the full range of the thermostat using the rotary switch inside the
appliance and the remote control hand unit. See
Lighting Instructions
further on in this manual for full details.
Aeration adjustment
As described on page 27, 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 31 on page 27. Evaluate the aeration only after the unit has warmed up—approximately 15 minutes.
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.
