Purge air should be provided via the purge air connection to 

reduce conducted heat and to keep the sight pipe and viewing 

head lens free of dirt and debris. Refer to “Purge Air” on 

page 8 for requirements. For electrical isolation reasons, the 

purge air line should be installed using and insulating material, 

such as a rubber hose, in between the purge air line and the 

viewing head. Note that an extension pipe may be required to 

locate the viewing head further from the burner front plate to 

avoid high temperatures. Additionally, an Ultem replacement 

insulating mounting block is available for all models, which is 

rated for 320F (160C) continuous service. Also available are 

cooling jackets which are used with vortex coolers. The 

Honeywell Ultem R-518-13 nipple or R-518-PT13/R-518-

PT13L locking coupler adapter and R-518-CL13-HTG locking 

coupler can also be used for heat insulation reasons. Refer to 

the Accessories section of this document for accessory part 

numbers.
