MAXITROL amplifier to set the burner at low fire.
b.
Set the burner at low fire with the adjusting screw intended for this purpose
and located on the MAXITROL modulating valve (see figures 5 and 6). The
burner should then be lit over its entire length.

FINAL AIR TEMPERATURE ADJUSTMENT
a.
Set the MAXITROL temperature selector (TD 114) to the desired final
temperature. This selector is located either in the control panel on the unit or
in the remote control station.
NOTE:
When the MAXITROL temperature selector (TD 114) is installed in a
remote control station, the wires used to make the connections must be
shielded wires (with metal sheath). The length of these wires is limited to 200ft
(60m). Consult the manufacturer for longer distances.
WARNING
With an adequate leak detection fluid, ensure that there are no gas leaks in
the piping.
Make the necessary repairs if needed.
Do not let the heater operate if a gas leak is detected.
