Installation - Columbia CT Series Installation, Operation And Maintenance Manual

INSTALLATION

The Columbia Model CT Steam Boiler is furnished completely piped, wired, and assem-
bled. It has been factory tested and is ready for operation. This steam boiler is designed
to operate using No. 2 fuel oil and/or natural, manufactured, or liquid propane (LP) gas,
and to be powered by standard AC electrical service.
BEFORE BEGINNING INSTALLATION, CAREFULLY STUDY THESE INSTRUCTIONS AND ALL
CHARTS, DRAWINGS, AND DIAGRAMS SHIPPED WITH THE BOILER.
Installation must follow all state and local code requirements. The electrical installation must
be in accordance with the National Electrical Code.
CLEARANCES
The boiler is to be placed on noncombustible flooring, in an approved boiler room, with
the following clearances to combustible materials.
Underwriters Laboratories (UL) approved clearances:
Side:
Top:
Front:
Chimney connector:
Reduced clearance installation must follow the recommendations as outlined in NFPA-31.
Reduced clearance installations should be avoided if possible, as this will make it much
harder for qualified technicians to perform routine maintenance in and around your
boiler.
Clearances to noncombustible materials shall be in accordance with state and local codes.
In the absence of local codes, it is recommended that the above stated clearances be fol-
lowed.
FLUE
The CT series boilers are pressure fired steam boilers, and need only to be properly vent-
ed. Consult the factory for proper venting of the boiler for any unusual conditions that may
exist at the job-site.
For boilers vented into a chimney, be certain the chimney is clean, and clear of obstruc-
tions. Connect the boiler flue outlet to the chimney using galvanized flue pipe. Refer to the
following list for proper size of the flue pipe. DO NOT REDUCE THE FLUE OR CHIMNEY SIZE
TO LESS THAN THE OUTLET SIZE ON THE BOILER. Consult the factory if the boiler must be
vented into a chimney that is smaller than the boiler outlet size. The flue pipe should be
pitched upward at least 1/4" per foot of run. Use only elbows and straight sections. Tees
