Window Refitting & Checking; Operation Checks - Valor 535 XAN Installation And Owner's Manual

• Refit the window with the bottom three bolts. The bolts should be screwed in securely.
• Refit the chain to the top right corner of the window.
• Refit the top three bolts securing by turning them through 90º.
• Pull the top of the window forward and release to check that it opens slightly and
returns in the event of a delayed ignition explosion. See figure 44.
• Similarly check the bottom of the window by pulling it forward and releasing. See
figure 45.

Aeration adjustment
As described in section 11, for natural gas appliances, the 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 sliding the shutter to
adjust the aeration by (See figure 35). 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.
