Ventilation Test - Beech ovens REC Series Installation And Operation Manual

Beech Ovens
RND-REC-RGO Manual (R1)
With the A4 sheet folded lengthwise the suction should not be able to hold the paper in
position at the flue spigot at the mouth of the oven. If the sheet stays in position the
System damper will need to be adjusted (closed slightly) to decrease the airflow.
In the case of multi door ovens or ovens fitted with a char grill, repeat these instructions
for all doors. (For ovens fitted with a Char Grill, suction is automatically biased to the
Char Grill side of the exhaust spigot)
Careful work here will increase performance and help to resolve problems otherwise
overlooked. Remember, too much suction removes great amounts of heat from this
style of oven. Correct calibration is critical.
This test is simple and approximate. Additional calibration may be required should
spillage be observed or if the exhaust spigot temperature exceeds the recommended
130-150°C (max).

Ventilation Test

As mentioned in the earlier section Venting the
Oven, for all ovens with gas, an open vent must
always be made available to the underside of the
oven. To sustain a flame, the oven utilizes
primary and secondary air (oxygen) from below
the oven floor.
When firing the oven with gas, if the flame
burns erratically check that the
flame is not being drawn
under the oven and
leaking from the blow-
back chute.
If flames are visible here, this
means there is an ambient pressure
imbalance. (Higher pressure in the oven –
Lower pressure below the oven)
If smoke or flames are visible during the Ventilation test, shut the system
immediately and refer to the section Ventilation Requirement.
