1). The burner will light. DO NOT operate the heater in any other than the full “ON” position. 9. IMPORTANT: DO NOT attempt to adjust the main burner input using the main gas supply valve, for this may cause the pilot and thermocouple to shut down the burner (Fig. 2). Shut-down instructions: To turn the heater OFF, • For short periods of time, turn the main burner off by rotating the gas valve knob clockwise to the “PILOT” position. • For extended periods of non use, turn the appliance completel

See the following drawings for typical examples. 1. Use only noncombustible materials for hangers and brackets. 2. A minimum No. 2 chain with a working load limit of 115 lbs. is required. 3. Turnbuckles should be used with chains to allow leveling of the heater. All “S” hooks and eye bolts must be manually crimped closed by the installer. 3. When using rigid means for heater suspension (rod, flat bar, etc.) provide sufficient lengths orswingjoints to compensate for expansion. See Figures b a

B) Check for loose or broken motor lead wire. C) Check to see that blower wheel turns freely and is not rubbing housing. Blower wheel may have worked loose from shaft and jammed against housing. D) Check for blower wheel damage; replace if necessary. If no damage, readjust blower wheel on shaft & retlghten set screw. E) If all above does not correct, replace motor. 31) CLEANING AND ANNUAL MAINTENANCE_ This heater must be cleaned and serviced annually before the start of each heating season and

Secure with 3/8” connectors as previously described in the attachment of the control box and draft inducer. Connect wire leads as shown in the Connection Wiring Diagram. The SJO cable should be located and secured to protect it from mechanical damage.

Avoid bringing combustion air to the heater from an attic space. There is no guarantee that adequate combustion air will be supplied. If the heater is installed less than 2 ft. from the ceiling, a flexible transition section (e.g., flexible aluminum duct) must be provided to allow for expansion/contraction of straight tube heaters (LTS series). In colder climates, where necessary, insulate the outside combustion air duct. Avoid locating the outside combustion air duct directly above the contro
