Oven Venting System - AGA TOTAL CONTROL TC3 Installation Manual

See Fig. 3
The pre-site installation visit will determine how the layout of the oven vent pipework should be
designed and how it is going to be installed. It is also necessary to check that the pipework
design and the pipework resistance are within the parameters possible and exit from one of
twopositions, as shown in Fig. 1, Page 5.
The appliance oven venting pipe can be achieved up to a maximum length of 6 metres, through
an outside wall. Great care must be taken in all-timber houses.
If the oven vent pipe passes through combustible material, there must be an air gap of at least
25mm around the pipe and preferably wrapped with insulation material.
The max supply to the motor, as calculated should be limited to 22V (DC), for ideal
operating conditions.
Calculating the voltage for the particular pipework is as follows:-
1. Keep the pipe run as simple as possible - avoid bends.
2. "Vertical risers" are not permitted.
3. Pipe run should be horizontal - slight downwards slope towards the fan.
Minimum 12 volts for first metre of vent pipe run inclusive of 1 bend
Each extra metre add 1 volt.
Each extra bend add 2 volts
Maximum allowed 22 volts.
Minimum setting is 15 volts.
NOTE: IN THE OVEN VENTING INSTALLATION, WHETHER FAN ASSISTED OR NATURAL
FLUE, PROVISION MUST BE MADE FOR EASY 'RODDING' OF THE PIPEWORK TO
FACILITATE CLEANING.
