Failure to comply with the stated clearances
to combustibles could result in personal injury,
death and/or property damage.
This heater should be installed so that the
minimum clearances to vehicles, as marked
on the heater, will be maintained. If vehicle
lifts are present, ensure that these clearances
will be maintained from the highest raised
vehicle.
!WARNING!

!WARNING!
!WARNING!
This heater must be installed and serviced by
trained gas installation and service personnel
only. Read and understand these instructions
thoroughly before attempting to install, operate
or service this heater. Failure to comply could
result in personal injury, asphyxiation, death,
fire, and/or property damage. Retain these
instructions for future reference.
NOT FOR RESIDENTIAL USE!
Do not use in the home, sleeping quarters,
attached garages, etc.
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 heater
to the combustibles. Signs must either be posted
adjacent to the heater thermostats or inthe
absence of such thermostats, in a conspicuous
location.
This is not an explosion-proof heater. Where
there is the possibility of exposure to flammable
vapors, consult the local fire marshal, the fire
insurance carrier and other authorities for
approval of the proposed installation.
!WARNING!

Product Summary
DES Series heaters are available from 20 to 60 foot, 50,000 to 175,000 BTU’s, natural or LP gas. DES Series are
positive pressure, single stage heaters and feature hot-rolled steel for it’s radiant pipes. DES Series heaters also
feature a direct spark ignition system.
Specific Mechanical Instructions
Be sure to identify the aluminized (50 - 125 MBTU/H) or titanium (150 -175 MBTU/H) combustion chamber and
place as the first tube section.
175,000 BTU/H models must be installed with a stainless steel tube clamp at the second joint of the exchanger
between the first and second ten foot radiant tube.
Note baffle quantities for your model and place baffles in the last tubes (farthest from the burner) as shown on pages
13-14 of the general manual.

DES Series - 4” Tube Heater Installation, Operation, Maintenance and Parts Manual
DES Series
Theory of Operation
·Starting Circuit (see internal wiring diagrams)
When voltage is applied to L1 and L2, 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.
Air pressure generated by the blower will cause the
normally open pressure switch to close. Another
circuit is completed from L1 to the spark ignition
module and back to L2. After a seven (7) second
pre-purge, the spark electrode and gas valve are
energized simultaneously. The trial for ignition is
fifteen seconds.
· 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 the 15 second trial for ignition, the
unit will retry two additional times before entering
lockout mode. If lockout occurs, the control can be
reset by briefly interrupting the power source.
Electrical Requirements
♦120 Volt - 60 HZ, single phase, 3-wire.
♦25V thermostat connection.
♦Starting Current 1.7 Amps.
♦Running Current 1.1 Amps.
♦24V controls.
♦Wiring must not run above or below the heater,
nor exposed to the radiant output.
♦Heaters must be grounded in accordance with
the National Electrical Code ANSI/NFPA70
(latest edition).
♦Observe proper electrical polarity.
It is recommended that the thermostat be installed
on the hot side of a fused supply line and have
sufficient ampere rating for the heater(s) that it
controls.
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’’
Ventilation Requirements
♦Consult the general manual for venting
instructions.
♦For unvented operation, 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.
