The 4055-X-ERA 10mm igniter is intended to ignite pilot tips
in Class 1 Div. 2 applications. It has a
¾
"-20 threaded igniter
connection for sealed aircraft type ignition wiring.
Although the wiring method used between the ignition
transformer and the spark plug was designed and chosen to be
suitable for use in Class 1 Div. 2 hazardous locations, it DO ES
NOT carry certifi cations or third party approvals.
The 8666 Testip facilitates setting air/fuel ratio when premix
fl ames are not easily visible. The Testip is installed in a positive
pressure mixture line and lit with a manual torch. Air/gas ratio is
adjusted in the mixer until Testip fl ame seems appropriate.
Testips are turned off and removed aft er the ratio has been set.
Since the Testip diverts some of the premix into itself, confi rm the
pilot ratio is still good aft er turning it off .
Use caution with 8666 Testips they are small burners and get
very hot when run. Outdoors, the fl ame can be diffi
cult to see in
direct sunlight. Testips will not work in systems that operate with
negative mixture pressure.
