Installation 

The probe tube (stinger) should be screwed into the 1/2” NPT fitting on the inside of the mounting flange. To 
prevent galling, coat the threads with an anti-seize compound. Remove and anti-seize compound from the 
inner wall of the probe tube before attaching it to the probe. The length of the probe should be selected to 
extend into the center third of the stack; or if the stack diameter is greater than 12’, at least 6’ into that stack. 
The studs on the mounting flange should be joined to the sampling nozzle on the stack and the assembly 
bolted into place. 
 
A heated sample line should be supported close to the Model 270. The heated sample line should be fed 
through the heat shrink boot on the bottom of the enclosure. Connect the sample tube to the center tubing 
fitting (3/8”) on the filter. The unheated portion of the sample line should be kept short and insulated to avoid 
condensation. Connect the calibration gas line to 1/4” tubing fitting located on the left side of the chamber and 
is connected to the chamber via a check valve. If the compressed air line is part of the heated sample line, it 
can be connected to the 1/4” fitting adjacent to the blowback accumulator. If an external airline is to be used 
for blowback, bring the air into the enclosure through a bulkhead fitting (supplied by others) to be installed in 
the wall of the enclosure, typically the mounting location is in the bottom of the enclosure, and connect the air 
to the same 1/4” fitting. 
 
Provide power to the terminal block(s) within the stack filter enclosure in the Model 270. 150 watts (without 
heated enclosure) or 350 watts with heated enclosure, at 115/230VAC is required. 

 

NOTE: The supply power circuit MUST include an overprotection device with a maximum 
rating of 20A. A disconnect switch must be located in close proximity to the probe. 

 

A thermal switch mounted in the aluminum heater will control the temperature to 340°F (171°C). 
Insure the power supplied to the heater matches the heater voltage requirement shown on the 
serial number tag. The voltage requirement can be changed by changing the jumpers on the 
terminal strips (reference terminal strip label or drawings for details). 

An independent ground 

wire should be run to the grounding terminal on the terminal strip. 
 

If an independent measurement and display of the oven temperature is desired, a temperature sensor can be 
slipped into a 1/8” diameter thermowell supplied on the heater tube assembly. 
 
The final installation step is to ensure that the sample line is insulated completely. Close the cover of the 
enclosure and secure the latches. After securing the heated sample line, use a heat gun to shrink the entry 
boot onto the sample line. The goal is to keep the temperature of the gas sample at a temperature above the 
dew point of the gas all the way from the stack to the sample cooler/dehydrator.
