This heater must be installed and serviced by
trained gas installation and service personnel
only. Read and understand these instructions
thoroughlybeforeattemptingto 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.
This is not an explosion-proof heater. Where
thereisthe possibility of exposure to flammable
vapors, consult the local fire marshal, the fire
insurance carrier and other authorities for
approval of the proposed installation.
Inlocationsusedfor 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 in the absence of such thermostats in a
conspicuouslocation.

Product Summary
DX2Series heatersareavailablefrom 20to80 foot,50,000to 200,000BTU’s,naturalor propanegas. DX2Series arepositive
pressure, single stage heaters and feature coated aluminized steel for it’s radiant heat exchangers. DX2 Series may also be
upgradedto stainlesssteelfor harshenvironment applications.
Operational Features
DX-2Series heaters includea gascock, flexconnector andall hanging accessories. Mostimportantly, theseheaters feature
coatedaluminizedheat exchangerscoveredbyhighlypolished aluminumreflectorsformaximumefficiency. Theseheatersalso
featureoperational indicatorlights,potted circuitboards,hot surfaceignition andturbulatorbaffles (forimprovedefficiencies).
Specific Mechanical Instructions
Be sure to indentify the titanium (150-200 MBTU/H) combustion chamber and place as the first tube section directly following
the burner box. The identification sticker found on the swagged end of the tubing will identify the titanium combustion tube.
175,000 and 200,000 BTU/H models must be installed with a stainless steel tube clamp at the second joint of the exchanger
betweenthe firstand secondradiant tubes.

· Starting Circuit
WhenvoltageisappliedtoL1andL2(seediagram
on right), a circuit is completed from L1 via the
blowermotor toL2. The blowerfan ismounted in
thecontrolboxandratedtosupplysufficientairfor
combustion.
Air pressure generated by the blower will cause
the normally open differential pressure switch to
close. Anothercircuit iscompleted fromL1 to the
hotsurfaceignition controland backto L2. There
is a five second delay, then the glo-bar is pow-
ered. After the glo-bar has been powered for 45
seconds,thecontrolcausesthegas valve toopen

Powerto theglo-bar isshut offduring thelast two
orthree secondsof the ignitiontrial.
· Running Circuit

Is the inlet or the outlet
of the unit obstructed
(i.e.ice,birds nest,dirt)?
NO Check for loose wiring or
resistance in hose connection to pressure switch. Are they ok?
NO
Remove obstruction.
The heater is equipped with a safety pressure switch. This differential switch, located in the gas valve compartment, is a normally closed switch. Temporarily place jumpers across the terminals of the switch. (Be sure to reinstall the cover.) Does the light energize?
YES
YES
Replace burned out light.
NO
YES
Replace the differential switch after verifyingthefollowing: * Baffle(s) is in the tube(s) farthest from the burner. * Heater, fan blower, squirrel cage, intake and exhaust are clean and free from dirt and obstructions. * The 4” air intake pipe does not exceed 20 feet and/or 2 elbows. * There is not a negative pressure experienced at the area of air intake (i.e. attic space, high-winds, very tight building).
If any of the previous were occurring,
please address the problem.
