A rack turntable option is fitted to selected models (FG166-G****TT), allowing the use of a
range of standard racks in the MONO MXTG oven.
Air circulation system
An electrically powered radial fan re-circulates air within the oven. Heated air enters the fan at the
upper left-hand side of the oven and is driven within the roof structure to the vertically orientated air
door at the rear corner of the baking chamber. Adjustable openings in the air door allow the
amount of air entering the baking chamber at various heights to be adjusted to get the optimum
baking result.
The air door openings are set at the factory and should not require resetting. The factory settings
are given in section –
Setting the Air Slots for reference. Should these factory setting fail to give a
satisfactory baking performance then instructions for adjusting the openings are given .
Steam system
The steam generating system is completely contained within the oven and situated at its left hand
side in the lowermost region of the air duct, outside of the baking chamber. Only cold water, at a
pressure of 2 bar (29 PSI) – 4 bar (58 PSI), needs to be connected to the oven for the purpose of
steam generation, domestic pressure is usually within this parameter.
The pressure reducing valve on the oven is factory set at 1.5 bar (22 PSI).
From a cold oven start the steam system will typically require 30 minutes to accumulate sufficient
energy to produce satisfactory steaming performance; and during repeated baking cycles it
automatically re-energises itself during the bake cycle. No drain is required for the steam system.
Under normal conditions of use this oven is not considered a pressure vessel.
Gas Heating System
The gas heating system consists of the gas supply pipework, a pre-mix burner, air-to-air heat
exchanger and flue outlet.
The gas burner is factory-fitted and must be connected to a natural gas fuel supply only. Every
burner is pre-set and no adjustment should be attempted. Gas is mixed with air supplied from the
room the appliance is situated in and burned to produce hot gaseous products of combustion that
flow through the internal passages of the heat exchanger and are kept separated from the oven’s
re-circulating air.
Heat is transferred to the baking chamber through the interaction of re-circulating air passing over
the hot surfaces of the heat exchanger.
After passing through the heat exchanger the products of combustion discharge from the oven
through the flue outlet terminating at roof level towards the rear left side of the oven. This oven is
intended to be connected to a flue in accordance with the specification and local authority
guidelines.
