4.Installation of Boiler Trim Components Cont.

1.Install L4006A aquastat in upper left or right rear tapping using 3/4” immersion well. All tapings and joints should be sealed with piping compound. The L4006A can be adjusted up to 220o F, and should be set to the desired temperature by the installer. The differential is also adjustable between 5 and 30 degrees. It should be set as close to 30 degrees as possible to prevent short cycling of the boiler. If you are installing a 7248U, Screw the unit to side panel of the boiler as close to the immersion well as possible using the tabs on the aquastat. Run the sensor from behind the aquastat to the immersion well and fix it according to Honeywell’s instructions. The 7248 can be adjusted between 140o F and 220o F with a fixed differential of 30 degrees.

2.Install Pressure Relief Valve in opposite, upper rear tapping using 3” nipple and 3/4” elbow

3.Install 3/4” boiler drain in lower left or right rear tapping, or lower front tapping.

4.install 3/4” plug in opposite lower rear tapping, and/or the other plug in lower front tapping of the boiler.

5.Install combination pressure/temperature gauge and 1/2” x 1/4” bushing in upper front tapping. The gauge must be tightened using a wrench and not your hand.

6.Install burner mounting hardware in the four tapings on the front of the boiler door.

7.Install boiler door bolts on opposite side of door hinge.
