WARNING!
In locations used for the storage of combustible
materials, signs must be posted to specify the
maximum permissible stacking height to
maintain the required clearances from the

LS Series - 3” Tube Heater Installation, Operation, Maintenance and Parts Manual
LS Series Mechanical Instructions
This supplement is designed to address the specifics of the LS Series - See page 12 for specific product features.
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.

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).

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.

Theory of Operation
Electrical Requirements
♦ 120 Volt - 60 HZ.
♦ Hot surface ignition.
♦ Starting Current 4.8 Amps.
♦ Running Current 1.1 Amps.
♦ 24V controls optional (24VAO).
·
Starting Circuit
When voltage is applied to L1 and L2 (see diagram
on right), a circuit is completed from L1 via the
blower motor to L2. 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.
