Connecting Water to the Coil Tube Boiler
1. Connect the desired header supply and return lines to the CTB.
2. Have the water trim installed by a certified hydronics technician according to the ASME
Section IV Boiler Code. Heat exchangers must be used for domestic water heater installations.
3. For air separation and elimination, Clean Burn recommends the Enhanced Spiral-Type Air
Separator which can be supplied by your local Clean Burn dealer. Installing an air separator
helps ensure that air is purged from the boiler, which is necessary for optimal startup and
operation of the burner.
4. The relief valve discharge must be piped to within four inches of the floor or to a floor drain.
Be sure to allow for clearance to remove the back panel for servicing.
Filling the Coil Tube Boiler with Water
ATTENTION: It is necessary to fill the CTB with water prior to wiring and turning the CTB ON.
The boiler circulator bearings are water lubricated and should not be allowed to operate dry. Filling the
CTB with water provides immediate lubrication of the bearings. Purging air from the water is also
critical; doing so enables proper startup of the burner.
1. Fill the CTB with clean tap water.
ATTENTION: To prevent damage to the CTB, DO NOT fill the boiler with water when the
boiler is hot.
2. The pressure gauge should read 20 psig. (If a different operating pressure is needed, contact the
Clean Burn Service Department for additional instructions.)
3. Refer to Section 10, The CTB Hydronic System, for additional information.
IMPORTANT NOTE! Detailed information on the installation and operation of the
hydronics system is provided in Section 10 of this manual. The instructions
provided here are abbreviated and serve only to indicate
when these procedures
should be performed; consult Section 10 for the detailed version.
