SENTINEL HEATERS: Assemble the strips and insert
into last tube, see Fig. 10. Edge of strip is
fl
ush with
end of tube.
OVAL 80 HEATERS: Both strips are
factory installed into the oval tube. At
installation, ensure strips are snugly fi t
into oval tube and do not extend past
end of tube.
Assemble the tee, nipple, and cap to the nipple at the
gas inlet of the heater. See Fig. 12. Use a wrench to
hold the pipe nipple when installing the sediment trap.
Tighten securely. The sediment trap assembly must
always be mounted in a vertical position. Check all
connections for gas leaks using approved gas leak
detectors.
1. Assemble the components together. See Fig. 13.
This view shows general assembly of the compo-
nents. The regulator must always be mounted so its
vent, regardless of location on the regulator, is al-
ways pointed downward. Ensure hose is positioned
away from the heater.
2. Tighten all connections securely and check
for gas leaks
