Pre-Installation Survey; Mounting Clearances - Schwank SEM 200-70 Installation And Owner's Manual

5. PRE-INSTALLATION SURVEY

The SEM(U) / IT(U) heating system must
have gas piping of the correct diameter,
length, and arrangement to function properly.
For this reason, a layout drawing is nec-
essary.

6. MOUNTING CLEARANCES

This heater must be mounted and positioned
to maintain the minimum clearance to com-
bustible materials as shown in FIGURE 1
(PAGE 6) TABLE 3 (PAGE 6). For recom-
mended heater placement refer to TABLE 2
(below). Heaters should also be located and
installed with respect to building construction
