Product Summary IMPORTANT LS Series commercial/residential tube heaters are available from 10 to 30 foot, 25,000 through 50,000 BTU’s, natural or LP gas. LS Series are positive pressure, single stage heaters and feature aluminized steel for it’s radiant pipes. LS MODELS APPROVED VENT PACKAGES 25,000 thru 50,000 BTUH 3-DSK RTVP-3 Figure 1 Specific Mechanical Instructions Be sure to identify the titanium combustion chamber and place as the first tube section. Do not use the aluminized steel radiant tubing as the first tube (combustion chamber). Radiant Tube For residential installations it is required that the appliance be vented. Venting must be 3 in. diameter (4 in. diameter for common venting). Refer to the flue venting guidelines, figure 1 and on page 19 of the General Manual. For residential installations mounted below 8 feet, it is required that Protective Guards (part # PG) are installed on heater (see figure 2). Reflector Protective Guard (part # PG) Figure 2 LS BAFFLE INSTRUCTIONS WITH TURBULATOR FINS Insert assembled baffles with HEAT Baffle preceeding the PRESSURE Baffles (fig. 1). Allow for turbulator fins so that the key hole is inserted first. All baffles must be placed vertically in the last radiant tube/heat exchanger (fig.2). Figure 1 HEAT BAFFLE 1st If the heater is installed with a U or Elbow fitting all baffle must still remain. There may be some instances where the baffle will be cut into two sections. Place as much baffle as possible downstream of the U or Elbow and the remainder of the baffle just before the U or Elbow fitting.

The blower fan is mounted in the control box and rated to supply sufficient air for combustion. Gas Requirements ♦ Manifold Pressure • Nat. 3.5’’ • LP. 10.0’’ ♦ Minimum Inlet Pressure • Nat. 5.0’’ • LP. 11.0’’ ♦ Maximum Inlet • Nat. 14.0’’ • LP. 14.0’’ Air pressure generated by the blower will cause the normally open burner pressure switch No. 1 to close. Another circuit is completed from L1 to the module ignition control and back to L2. There is a five second delay, then the glo-bar is powered. After the glo-bar has been powered for 45 seconds, the control module causes the gas valve to open and initiates the ignition trial. Ventilation Requirements ♦ Residential models must be vented. ♦ Consult the generic supplement for venting instructions and unvented operation. Power to the glo-bar is shut off during the last two or three seconds of the ignition trial. ♦ For unvented operation (commercial use only), there must be a positive air displacement of at least 4.0 CFM per 1000 BTU/H for natural gas or 4.5 CFM per 1000 BTU/H for LP gas. WVE-4 termination cap must also be used. · ♦ Maximum vent length for all models is 20 ft. Running Circuit After ignition, the flame rod monitors the flame. As long as a flame is present, the valve is held open. If the flame is lost, the control acts to close the valve within one second, and a new trial sequence identical to that at start-up is initiated. If proof of flame is not established within 8.5 seconds, the unit will lock out. If lockout occurs, the control can be reset by briefly interrupting the power source. Approved & Required Vent Caps Sidewall Single ♦ 3’’ Duravent sidewall vent kit (3-DSK). ♦ 3’’ Vent terminal (SWD-3). Sidewall Dual (Sharing common t-stat) ♦ 4’’ Duravent sidewall vent kit (4-DSK). ♦ 4’’ Vent terminal (SWD-4). Roof Single ♦ Approved 3’’ rooftop raincap (RTVP-3). Roof Dual (Sharing common t-stat) ♦ Approved 4’’ rooftop raincap (RTVP-4). Important: Do not use sidewall caps for roof venting and do not use roof caps for sidewall venting. 4 LS Series - 3” Tube Heater Installation, Operation, Maintenance and Parts Manual Internal Wiring Diagrams LADDER DIAGRAM - MARK17DU-117 WITH THERMO L1 L2 120VAC BLOWER BK BK INDICATOR LIGHTS BK BK BK BK GAS VALVE BK BK THERMO SWITCH PRESSURE SWITCHES R BK O W BK W G GND NEUT VALVE NEUT TH LINE1 PROBE IGNITOR SIC1 W BR IGNITION MODULE IF ANY OF THE ORIGINAL WIRE AS SUPPLIED WITH THE APPLIANCE MUST BE REPLACED, IT MUST BE REPLACED WITH WIRING MATERIAL HAVING A TEMPERATURE RATING OF AT LEAST 105 C.
