OVEN VENTING SYSTEMSSee Figs. 7, 8, 9 & 10Pre-site visiting will have determined where and how the layout of the oven vent pipework should be designed andinstalled. It is then necessary to check that the pipework design and the pipework resistance are within the parameterspossible.The appliance oven venting pipe can be achieved, up to a maximum length of 6 metres, through an outside wall or unusedflue etc. Great care must be taken in all-timber houses.If the oven vent pipe passes through combustible material, there must be an airgap of at least 25mm around the pipe andpreferably wrapped with insulation material.Setting the Vent Fan (Motor Speed)Setting of the motor speed is carried out by adjusting the Voltage Regulator (VRI) on the controller PCB in conjunction witha voltmeter. (See Fig. 8).The max supply to the motor, as calculated in Fig. 8, should be limited to 20v (DC), for ideal operating condition.Calculating the voltage for the particular pipework layout is as follows: (See Fig. 7).Alternative Oven Venting SystemsVenting may be achieved directly into the flue providing a stabiliser is fitted. See Fig. 9.NOTE: IN THE OVEN VENTING INSTALLATION, WHETHER FAN ASSISTED OR NATURAL FLUE, PROVISION MUSTBE MADE FOR EASY ‘RIFLING’ OF THE PIPE WORK TO FACILITATE CLEANING.Fig. 7 - Voltage Circulation Fan9DESN 513942
