INSTRUCTIONS FOR INSTALLATION OF RUBBER BAFFLE STRIPS
(Horizontal Baffle Seals)
The following is the procedure for installing rubber strips on MEAH
heat exchanger tube bundles:
1. After removing the tube bundle from the casing, remove old
strips and tie down plate at stationary tube sheet. (Tie down
plate is not on all models.)
2. Remove all grease and dirt and clean to bare metal.
3. Apply a one inch wide coat of adhesive to both the steel baffle
and the rubber baffle strips. (Bell & Gossett uses Barge
cement.)
4. After the adhesive becomes “tacky,” press the rubber strip
firmly into place. Make sure the strip is flush against the sta-
tionary tube sheet.
5. Allow the adhesive to set up for about one hour, replace the tie
down plate and replace the tube bundle into the casing.
