Mounting Clearances; Service Clearance - Schwank UHE Installation And Owner's Manual

Installation must conform with all local, state, provincial and national code requirements includ-
ing the current latest edition ANSI Z223.1 (NFPA 54) in the U.S.A. and B149.1 installation
code in Canada, for gas burning appliances and equipment. The latest edition Electrical Code
ANSI/NFPA N0 70 in the U.S.A. and PART 1 CSA C22.1 in Canada must also be observed.
The heating system must have gas piping of the correct diameter, length, and arrangement to
function properly. For this reason, a layout drawing is necessary.

6. MOUNTING CLEARANCES

This heater must be mounted with at least the minimum clearances between the heater and
combustibles as shown in FIG-1, TABLE 1, Page 3. It is the installer's responsibility to ensure
that building materials with a low heat tolerance which may degrade at lower temperatures are
protected to prevent degradation. Examples of low heat tolerance materials include vinyl sid-
ing, fabrics, some plastics, filmy materials, etc.
Positioning of lights, sprinkler heads, overhead doors, storage areas, gas and electrical lines,
parked vehicles, cranes and any other possible obstruction or hazard must be evaluated prior
to installation.
Ensure adequate clearance around the air intake at the burner to allow sufficient com-
bustion air supply to the heater.
6A. SERVICE CLEARANCE: The lower 'jaw' of the burner cabinet swings down to provide
convenient service access to burner components. Provide a minimum clearance from any wall
or obstruction of 6 inches (15 cm) to the access end of the burner housing, and a minimum of
24 inches (61 cm) to any ONE side to allow servicing of burner, blower and controls. (see Fig-
ure 2) - the minimum clearances to combustibles must always be maintained.
For guidelines to heater placement refer to TABLE 2 (below).
