Regardless of an architect, engineer or oven manufacturers recommended fan selection... flue height and operating temperatures should be considered before installation of any fan.

 

Fan Fail.....

Typically, fan failure is due to excessive termination temperatures and/or a poor maintenance schedule.

Especially in a wood burning application... the fan, as well as the flue system should be inspected regularly to manage grease and creosote build up.

Start up and normal operation temperatures should be checked at the termination during initial installation of any fan....

The flue gas temperature before moving through the fan, should not exceed the recommended 575F (300C) intermittent / 482F (250C) continuous.

   

 

 

The end result from a finely tuned pizza oven can only be maintained when the same attention and commitment is kept from the oven's deck to fan.

   

Regardless of an architect, engineer or oven manufacturers recommended fan selection... flue height and operating temperatures should be considered before installation of any fan. 

The easiest and most economical way to lower termination temperature is with RSD Dilution Bolts.

The RSD dilution bolts are used to lift the fan above the chimney or the steel chimney adapter. The dilution bolts are designed to obtain a vibration-free operation as well as to allow dilution air to enter the fan to cool off the flue gases.  Dilution bolts are used for applications where the flue gas temperature, or the temperature of the exhaust going through the fan, exceeds 575F (300C).

It is recommended to check termination temperatures during any fan/motor repair.
Adding dilution bolts could extend a fans operating expectancy.

FSC - Fan Speed Control

FSC5 - 5amp Speed Control

FSC8 - 8amp Speed Control

Never have a pizza oven fan on an "on/off" switch...  
FSC - Fan Speed Control  

ENERVEX Fan Speed Control FSC is used in conjunction with all single-phased chimney fans. The fan speed control is specially engineered to provide variable speed control of split capacitor motors. The control is accomplished by reducing the line voltage to the motor thereby using only the energy required to maintain the desired volume of air flow (fan speed).

A pizza oven fan must run during the ovens entire cooking operation... failure to keep the fan on can result if fan failure.

Use the FSC variable fan speed control to dial in the perfect draft and maintain a constant oven temperature.

Especially in a wood burning application... the fan, as well as the flue system should be inspected regularly to manage grease and creosote build up. Don't wait....
A chimney fire from an unmaintained fan or flue system can shut a kitchen down.

A costly repair/replacement that can be avoided.

This larger GSV series fan was destroyed in a chimney fire. 

The extreme heat actually melted an aluminum cover plate off its impeller wheel.

This GSV12 Pizza Oven Fan also endured through a chimney fire.  The heat generated within the case acted like a kiln melting metal that can be seen oozing out the bottom weep holes. 

There is a working GSV fan on a separate flue adjacent to this fan fail, partially seen at bottom right of photo.  Notice the grease/creosote trail dripping over at the edge of the upper fan vent. 

An inspection and cleaning was advised as this fan may undergo the same fate unless properly maintained.


 

 

   
   
The Chimney fire through this GSV melted almost anything aluminum... especially around the top corner vents and bottom inlet collar.

Aluminum "nuggets" were found down in the pizza oven as well as on the roof around the flue system with some melted into the roofing.
