STV-JZ Manual
RD: MAR 2009
RL: 07A - BA
IMPORTANT:
Do not install the thermostat or sensors in the direct radiant stream.
WARNING: The heater must be electrically grounded in accordance with the Na-
tional Electrical Code. ANSi/NFPA 70 or current Canadian Electrical Code.
16. HIGH ALTITUDE INSTALLATIONS
Canada: All of the STV-JZ radiant tube heaters
are approved for altitudes zero to 4500 feet above
sea level and do not require de-rating.
15. ELECTRICAL AND THERMOSTAT WIRING
(SEE WIRING DIAGRAM PAGE 23)
Wiring must be done in accordance with local
codes. The total load of all heaters must be con-
sidered in determining the required contact rating
of the controlling thermostat or switch. Each tube
heater requires 120V, 60 HZ electrical power
sized for 145VA.
The heater can be controlled by the Tru-Temp
Thermostat, a line voltage Thermostat or by an
“ON/OFF" switch. Any heater(s) intended for
24v thermostat control must be ordered with the
24v control options.
USA: If a heater is to be installed at altitudes
above 2000 ft, the input must be reduced by 4%
per 1000 ft. If your local utility de-rates the heat
content in the gas supply, no modification of the
heater is required. If the gas supply is not de-
rated, the orifice must be changed according to
the chart on page 34. Check with your local utility
regarding de-rating of this appliance.

The voltage at the spark ignition control is 24V.
Note that proper functioning of the heater will be
adversely affected if the input voltage varies by
more than +/- 10%. Ambient Temperature rating
is minus 40°F to plus 175°F (-40°C to +79°C).
