THERMO SAFETY ALARM

The unit incorporates a thermo safety shut-off. In the event of electron-

ic failure, an internal “snap disc” will cut off power to the unit until it is 

manually reset. To reset oven, unplug the unit, locate ‘SNAP DISC 

HOLE PLUG’ (FIG. 5) in the back of the unit. Remove plug and with a 

NON- METEAL

 rod press on the button to reset.

Connecting to the Exhaust Chamber Adapter (Optional)

The optional exhaust chamber adapter is used to vent oven chamber fumes and heated moisture-laden  air  to  a  building's  

exterior  for  the  purposes  of  minimizing  excess  heat,  humidity  or  unpleasant but otherwise harmless fumes within an 

interior working environment.

The  exhaust  chamber  system  as  a  whole  is  not  designed  for  use  to  remove  harmful  

or  flammable  gases or vapors since the oven itself is not rated for use with such materials

It is recommended that the attached exhaust chamber and piping be checked once a year for any obstruction from dust,  

dirt,  or  material  process  "plaque"  build-up  from  processing  certain  materials.    Check  with  the  manufacturer  of  the  

materials  used  in  your  process  if  heating  the  material may produce a bi-product or out gassing that may build up on the 

interior surface of the oven, exhaust chamber or piping and present a fire hazard over time.

       Contact  an  HVAC  engineer  for  assistance  with  installation  or  questions  regarding  proper  venting  requirements  

in  your  specific  building  or  location,  and  if  any  local  or  national  fire  or  safety  codes  may apply for your application 

or process. 

   

Connect the exhaust chamber adapter with standard 3" or 4" diame-

ter single or double-wall steel or galvanized pipe.    

   

A minimum of 4 inches of clearance should be maintained between 

the connected pipe and any building surface or material. (FIG. 6)

  

For best performance, run a short pipe horizontally (3  feet  max.) 

directly  through an exterior wall. 

For vertical runs the exhaust pipe should  not  have  more than one (1) 

90 degree elbow, a maximum horizontal run of 3', and a  maximum of 15' 

vertically. Exceeding these recommendations may cause improper 

ventilation. 

Poor exhaust quality would be indicated by an excess of fumes and or 

vapor from around the door gasket versus what would normally be pres-

ent if no exhaust venting was used. 

Piping run lengths can be  extended beyond recommended maximums 

where a connection to  an existing ventilation or exhaust system provide 

a larger pipe diameter  and/or a mechanically powered draft that 

provides a negative pressure at  the point of connection. Mechanically 

powered vent systems work best to  eliminate fumes and moisture 

vapors, but depending on vacuum strength at the point of connection, it 

may slightly reduce the oven's time-to-temperature and recovery perfor-

mance.
