a separate regulator must be installed ahead of the
heater.RefertoFigure2formaximumallowablepres-
sure for stated model and gas.
See heater rating plate for minimum gas supply pres-
sure “For the Purpose of Input Adjustment”
On a multiple heater installation it may be possible to
use one large capacity regulator or an individual regula-
tor for each heater. Nevertheless, it is recommended
practice to make the entire pipe system a loop. Contact
your local representative or the factory for proper gas
pressure reducing design stage.
WARNING: DO NOT EXCEED ½ P.S.I. INLET PRES-
SURE TO HEATERS SHOWN IN FIGURES 1 AND 2
6. ELECTRICAL
Allexternalwiringmustbeinaccordancewiththe
existingelectricalcode.Usewiringdiagramfurnished
with heater. Be sure electric supply characteristics
match those called for on the name plate. The unit
must be electrically grounded in accordance with the
National Electrical Code, ANSI/NFPA70, latest revision.
In Canada refer to Canadian electrical code CSA C22.1
7. THERMOSTAT & LOCATION
Make sure that the electrical characteristics of the
thermostat match those of the heater controls. For best
results thermostat should be positioned 5 ft. above
floor where air can circulate freely around it. DO NOT
MOUNT directly to cold-side wall, in direct drafts or
directly beneath the infra-red heater.
8. VENTILATION
a.Theminimumintakeandexhaustairopeningsshallpro-
vide for not less than 400 CFM for every 100,000 BTU
inputexceptthattheinltrationareamaybeincluded
intheintakearea.Theexhaustfanmustbeinterlocked
withtheheaterthermostat.Ifapowerexhaustfan
is used, it should be controlled by the thermostat or
humidistat
b.Wherenatural(gravity)ventilationisprovidedfor
exhaust,theopeningsmustbedistributedabovethe
heaters(preferablyatthepeakoftheroof)andthe
areas of openings shall not be less than 300 square
inches for every 100,000 BTU input.
9. OPERATIONS
Upon completion of electrical wiring, gas piping and
purging of gas lines to heaters, refer to the lighting
instruction plate attached to heater for proper lighting
procedure.
10. CLEANING INFORMATION
Blow out Venturi and burner face with compressed
air(25#max.pressure);alsocleanorices(seeFigure
2forcorrectsizedrill).Fordetailedmaintenanceand
cleaning instructions contact your local representative
or factory.
