INSTALLATION
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, Fire and Underwriters regulations, and
standard plumbing practices. The electrical installation shall be in accordance with the National
Electrical Code.
Remove all boiler components from packaging and inspect prior to assembly to ensure that damage
has not occurred in shipping.
BOILER ROOM
Locate the boiler in a well lit area on a noncombustible, level floor. Make available a convenient water
supply and allow adequate drainage, including unobstructed floor drains, for flushing and filling the
boiler. Provide sufficient make-up air for combustion at all times. Power the boiler using a properly
rated electrical service. Include fused disconnects for control circuits, blower motor circuits, and feed
pump circuits that require a motor contactor or motor starter relay.
Where possible, place the boiler on a 3 inch concrete pad. Allow adequate clearance between the
boiler and any walls or obstructions to permit inspection and service on burner, boiler piping, controls,
or combustion vent.
DO NOT install exhaust fans in or near the boiler room. Exhaust fans steal available make-up air dur-
ing burner operation; and more importantly, when the boiler cycles off, exhaust fans pull hot flue
gases back through the burner causing burner parts to deteriorate, and to eventually fail premature-
ly. Maintain a positive pressure in the boiler room at all times.
Do not allow your boiler room to become a storage room.
VENTING
All Columbia boiler models utilize a pressure fired burner and need only to be properly vented. For
situations where unusual conditions may exist, consult the factory for proper venting.
Locate the boiler as close as possible to the chimney or other approved exhaust vent. For boiler mod-
els with a rectangular flue outlet, first bolt the supplied smokehood in place. Attach all flue piping to
the round flue connection and make each connection secure. The flue pipe should not be inserted
beyond the inside wall of the chimney.
DO NOT REDUCE THE SIZE OF THE FLUE OUTLET OR FLUE PIPING.
Columbia Boiler recommends the use of galvanized B Type vent for stack connections suitable for
temperatures to 550F. The flue pipe should be pitched upward at least 1/4” per foot of run. Avoid the
use of tees, sharp bends, and long horizontal runs. Install a draft regulator if required.
