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

The tube heater is operated by the building's environ-
mental control system. To accomplish this, the heater
must be connected to an electrical outlet controlled by
a relay or set of contacts that is closed and opened by
the building controller.
A series tap thermostat may be used to operate the
tube heater.

Start-Up Instructions
Follow steps 1 - 6 on initial start-up after heater
installation. For normal start-up, set building control
thermostat above room temperature. The heater will
start.
1. Open all manual fuel supply valves and check
for gas leaks using approved leak detectors. The
gas control valve has a manual shut-off feature
incorporated into the valve assembly. Ensure the
indicator on the valve is turned to the ON position.

2. Connect the electrical cord to an approved electri-
cal outlet.
3. This heater includes a direct ignition control
module for purposes of controlling the timing of the
ignition process of the heater as well as monitoring
of the safety functions. A red FAULT LED (light
emitting diode) is on the burner box. A flash-
ing red light identifies a problem in
the operation of the heater. Refer to the
troubleshooting decal on the interior of the access
panel for assistance in troubleshooting.
4. On a call for heat, the ON green light will be lit and
the motor will start up and run for five (5) seconds.
