1.10 GAS PRESSURE
A test point is located on the manifold, behind control
panel. Solid top, single and double tier oven model
access is gained by removing the panel as described
in Section 3. Access on open top models is gained by
removing top facia panel.
An adjustable governor is supplied for natural gas
units. Propane unit pressure is controlled by the
incoming supply regulator.
For multiple burner natural gas units, set pressure at
15 mbar with approximately half the total heat input of
the appliance in operation.
1.11 BURNER AERATION
Fixed injectors are fitted and no means of adjusting
the full gas rate is provided. After setting working
pressure as Section 1.10. Check burner aeration.

Oven
An aeration shroud is located close to the injector at
the end of the oven burner. Check that aperture
dimension areas shown in Figure 1. This will achieve
desired cone length. If the burner is over-aerated, the
flame may extinguish at low rates. The correct full
rate cone lengths for natural gas is 25mm. Slightly
yellow flame tips are acceptable on propane units.
Figure 2
Open Top
Check aperture dimension for natural and propane
gas is as detailed in Figure 2. Check that flame is
stable and there is no evidence of flame lift.
Figure 3A
Figure 3B
Solid Top
Check aeration shroud is located in position shown in
Figure 3A. There should be no flame lift or lightback.
Flames should be blue although slight yellow tipping
is acceptable for propane operation.
Injector should be located centrally within burner
venturi as detailed in Figure 3B.
