Mounting Clearances; Service Clearance - Schwank primoSchwank Installation & Owner's Manual

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 7. The clearances to combustible material
represent a surface temperature of 90 F° (50 C°) above ambient. It is the installer's responsibil-
ity to ensure that building materials with a low heat tolerance which may degrade at lower tem-
peratures are protected to prevent degradation.
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: To allow servicing of burner and controls, provide a minimum
clearance of 24 inches (61 cm) from the gas supply / ignition-controls of the heater to a wall or
obstruction . (see Figure 2 below) - the minimum clearances to combustibles must always be
maintained.
For guidelines to heater placement refer to TABLE 2 (next page).

7. HEATER MOUNTING / PLACEMENT
The primoSchwank / supraSchwank Combined Intensity Heaters are approved for both hori-
zontal and angle mounting.
When angle mounting, the short axis may be rotated to a maximum of 30° with
IMPORTANT:
the venturi always in the upper position. Improper angle mounting can result in
damage to the heater or unsafe operation.
For either horizontal or angle mounting, the long axis of the heater must be level. Use
only non-combustible mounting hardware.
