SECTION II. – INSTALLATION PROCEDURE
This equipment shall be installed and wired in accordance with regulations of the National
Board of Fire Underwriters, National Electric Code, and local governing bodies. The
following recommendations are not intended to supplant any requirements of federal,
state, or local codes having jurisdiction. Authorities having jurisdiction should be con-
sulted before installations are made. Local codes may require additional safety controls
and/or interlocks.
A. HANDLING THE EQUIPMENT
The Counterflo heater has been designed for rigging and handling through the use of
special lifting lug hooks installed on the sides of the unit. As explained previously, the
standard unit is designed for shipping in one piece. Optional accessories must be field
mounted. Figure 1 depicts a typical Counterflo heater for vertical floor mounting.
When unloading and setting the heater, use the lifting lugs provided or move the heater
on rollers. Hooks, jacks, or chains must not be used around the casing, exhaust fan, or
main control panel.
To be properly set, the Counterflo heater should be placed on a solid foundation and set
exactly as detailed later.
During transit, unloading, and setting of the unit, bolts and nuts may have become
loosened, particularly in the pillow block ball bearing assemblies in the fan section. It is
recommended that all nuts and set screws be tightened. Turn fan shaft by hand to make
certain that blower does not rub against blower housing, and that bearing lock rings are
tight.
Open the cover on the electrical control box located near the middle on the side of the
burner section. Box can be opened by turning main disconnect switch to the “off”
position. Inspect all wire terminals and wiring terminations to ensure that all connections
are tight.
B. POSITIONING THE HEATER
Locate the heater exactly level, making certain the minimum clearance is maintained
between the heater, and any combustible material. The Underwriters Laboratories Inc.,
listing of the heater stipulates the following clearances: 48” at the burner end, 18” at the
rear, both sides and top. The exhaust stack clearance must be 18”. See page 11 for
stack details.
For convenient access for maintenance, provide 24” clearance at the right side, as seen
when facing the burner, and 36” at the rear. Position the heater, if practical, with the left
hand side (as seen from burner end) next to any adjacent wall.
