5. PRE-INSTALLATION SURVEY
The STW-JZ / IW heating system must have
gas piping of the correct diameter, length, and
arrangement to function properly. For this rea-
son, a layout drawing is necessary.
Carefully survey area to be heated. For best re-
sults, whenever possible, place burner and
combustion chamber in coldest area.
One side panel of the burner accommodates the
gas and electrical connections into the burner
making it much more difficult to remove.
Although this side of the burner box could be
removed (if necessary) it is much easier to re-
move the opposite plain side and sliding the
panel onto the gas pipe. When installing close
to a wall a Left to Right tube installation is
ideal to position the access panel outside. For a
Right to Left tube installation approx. 24”
clearance is required to service the burner,
blower and controls
6. MOUNTING CLEARANCES
This heater must be mounted with minimum
clearances between the reflector surface and
combustibles, as shown in FIGURE 1 (page 5),
TABLE 3 (page 5).
For recommended heater placement, refer to
TABLE 2 (below).
Position heater relative to building wall and
equipment to maintain a minimum clearance of
24 inches from the side of burner access panel
for servicing and cleaning of burner, blower
and controls. Access panel is on the right hand
side of the heater looking down the burner to-
ward the vent end.
TABLE 2 RECOMMENDED HEATER PLACEMENT FOR INDOOR APPLICATIONS
IMPORTANT: Continuous operation of single or multi-heater
must not cause combustible material or materials
in storage to reach a temperature in excess of 160
