INSTALLATION
Planning the Installation
Proper flame detector application is the basis of a safe and
reliable flame safeguard installation. Refer to the burner
manufacturer instructions as well as to those included here.
Follow all instructions carefully.
Determine the Location
Before beginning the actual installation, estimate the best
location for mounting the detector based upon the following
factors:
Temperature
Install the flame detector where the surrounding temperature
will remain within the specified ambient operating temperature
ratings.

ASPIRATOR
For the C7076A, to keep the detector temperature within
specifications, the aspirator temperature must not exceed
225°F (107°C). If the aspirator temperature will exceed
temperature ratings, the introduction of cooling-purging air will
be required.
Vibration
Do not install the detector where it could be subjected to
excessive vibration; it shortens the life of the electronic
components. Vibrations with a magnitude greater than 1g will
require an antivibration mount to cushion the detector.
Clearance
Make sure there will be enough room to swing out the detector
for servicing. Refer to Fig. 2 as applicable.
Radiation Sources Other Than Flame
Examples of radiation sources, other than flame, which could
actuate the detector system include:
