Basic Heater Operation
Sunpa k® 534-TSH is a two-stage outdoor gas-fired
infrared heaterwhich is operated with awired switch. The
heatercan be operated at a HIGH setting with an in put of
34,000 BTU/Hr or at a LOW setting of 25,000 BTU/HR.
These heaters require a 24 VAC power source.
The fact that these heaters are hardwired to athree-way
switch makes the S34-TSH well suited for commercial
installations. There are no batteries or remote-control
devices to be misplaced. The robust lighted switch makes it
easy to see whether the heater is ON. Switch is prewired
specifically for the Model S34-TSH. Switch is made for 24
VAC only.
SUNPAK® S34 TSH INFRARED HEATERS
NOTE: Sunpak Heatershown with optional Face Trim
The Sunpak® S34-TSH should always be started up and operated on the High mode for the first 5 minutes to allow
the heater to warm up. Starting up the heater on the LOW mode before the heater is warmed up may cause the
heater to shut down prematurely. To correctthis situation, press the OFF followed by HIGH.

Pa rt No. 12052
TSH Switch with Light
3
Sunpak® heaters have a spark ignition and electronic
flame safety control. The pilot is only ON while the heater
is operating. If the flame safety sensor fails to sense flame
at the pilot, the heater will shut down and lockout. This
may happen due to low gas pressure or a gustywind. To
restart the heater, first set the switch to OFF before
restartingthe heater.
Although these heatersare designed for outdoor
installation and use, it is important that switches,
transformers or other operatingcontrols be protected
from the weather.
The TSH Switch with light is intended for 24 VAC only.
Two input wires hook up to the 24 VAC Transformer.
Polarity must be observed if you are connecting two or
more heaters. Three output wires connect to the heater
for common, low fire and high fire. The blue light on the
switch shines continuouslywhenever the heater is on.

Heater Layout and Design
Sunpak®heaters were specifically designed to provide
heated comfort in an outdoor environment. They have been
used on outdoor patios acrossthe United States and
Canada for over 30 years. When properly integrated into a
patio design, Sunpak®heaters generally increase the
comfort level 5° to 10° Fahrenheit outdoors. The heating
effectiveness will depend on air temperature, wind velocity
and other factors. Whenever possible other local Sunpak®
installations should be reviewed to determine the
effectiveness for regional environment.
The environments in which Sunpak®heaters are utilized
vary greatly. As an outdoor rated heater it has passed basic
wind and rain tests. This does not mean the heatercannot
be damaged bythe environment or when operated in very
windy conditions. Forthis reason it is strongly suggested
that heaters be inspected and if necessary repaired
annually or before each heating season.
The variable environments in which Sunpak®heaters are
applied means thatthese general guidelines are generated
by necessity and may need to be refined for local
conditions. These guidelines are to be used in combination
with the installation instructions.
SUNPAK® 534-TSH INFRARED HEATERS
Patio Design Consideration
Heater placement is critical for effective and efficient
patio heating. If heaters are placed too close together or
mounted too low, people become uncomfortable. If heaters
are placed too far apart on a breezy, wind-swept patio the
patio may never getwarm.
Sunpak® heaters work best if they are placed in areas of
the greatest heat loss, such as the open side of a semi-
protected patio area. The Sunpak®heater may be mounted
at up to a 30 degree angle or face down. Note that the top
clearances required from combustible material increases
when heaters are at an angle. The heater must always be
horizontal to the floor. Never mountthe heater in the
vertical position.
Breezy conditions must be considered when heating
any patio. Windbreaks can be extremely effective in
increasing comfort and reducing heating costs.
Windbreaks must be designed in such a way as to allow
the necessaryfresh air and ventilation for proper heater
operation (see ventilation of installation section).
Sunpak®heaters must always be operated in a location
that allows uniform air pressure around the heater. If only
part of the heater is located in a wind protected zone
damage to the heater mayoccur. Time should be taken to
observe how the wind will affect the heaters under local
conditions.
MINIMUM CLEARANCE FROM COMBUSTIBLE MUST BE MAINTAINED (see chart on page 6 & 7)

SUNPAKwill raise the comfort level 5-10° Fahrenheit outdoors.
The above coverage table was based on still breeze conditions.
Under windy conditions more heatwill be required. It is
recommended that a windswept patio be designed with wind
breaks to stabilize the patio environment. Wind breaks shall NOT
interfere with the ventilation or combustion air requirements of the
heater(s) and meet clearance for combustible requirements listing
on page 6 & 7.
WARNING: Severe updrafts such as you might get on a raised
terrace or rooftop patio can cause damage to the heater.
4
ANGLE MOUNTING: Most applications of the
SUNPAK ®b heater may be angle-mounted to a
maximum of 30° to accommodate mounting the
heaters around the edges of the patio. Note thatthe
top clearance to combustibles increases when heater
is tipped from the horizontal.
NOTE: Local codes may have special requirements
regarding head clearance requirements. Some local
codes require all portions of overhead radiant
heatersto be located at least 8 feet above the floor.

Clearances
Each heater must be installed such that the following
"Minimum Clearance to Combustible Materials' are maintained.
Combustible materials include wood, compressed paper, plant
fibers, plastic, Plexiglas or other materials capable of being
ignited and burned. Such materials shall be considered
combustible even though flame-proofed, fire retardant treated
or plastered. Additional clearance may be required for glass,
painted surfaces, vinyl siding or other materials which may be
damaged by radiant or convection heat.
Adequate space around each heater is required even when the
materials surrounding the heater are non- combustible to
provide adequate combustion air and ventilation of exhaust
gases. Heatersshould never be located in a ceiling recess or
anyform of ceiling enclosure.
The stated clearance to combustible materials represents a
surface temperature of 90°F (32°C) above room temperature.
Building materials with a low heat tolerance (such as plastic,
vinyl siding, canvas, tri-ply, etc.) may be subjectto degradation
at lowertemperatures. It isthe installer's responsibility to assure
that adjacent materials are not subject to degradation.
In locations used for storage of combustible materials, signs
shall be posted to specifythe maximum permissible stacking
heightto maintain required clearances from the heater to
combustible materials.

7. Installation of 1/8"N.P.T. plugged tap accessible
for test gage connections is required upstream of
the gas supplyconnections to the heater.
8. Never use pipe sealing compound on brass to
brass flared fittings.
Electrical
1. Sunpak S34-TSH Heaters need 24 VAC to operate.
A special lighted switch is provided which also
requires 24 VAC. In sizing your step down
120V/24V transformeralways allow for a current
draw of 20 VA per heater. A 24V-40VA
transformerwill operate two heaters.
2. If any of the original wire supplied inside the
appliance must be replaced, it must be replaced with
wiring material having a temperature rating of at
least 105degrees Centigrade.

shall be above the level of the heaters.
3. Heater ventilation must complywith state and local
codes. Never use heater in a fully enclosed
area.
Fire Sprinklers
Fire Sprinklers must be located at an appropriate
distance from each heater to avoid accidental activation of
the sprinkler. Ethylene glycol or propylene glycol must
never be used in fire sprinkler systems where heaters are
present as these substances may become flammable
when heated. A fire sprinkler professional must be
consulted when heaters are installed where fire sprinklers
are present to insure that heaters and the fire sprinkler
system are properly integrated. Specific guidelines can be
found in NFPA 13 regarding design and specifications for
Fire Sprinkler Systems near heaters.
Initial Start-Up Procedure
(Read entire Procedure First)
1. Before turning ON your new heatermake sure:
a. Heater is securely mounted and clearances from
combustible materials have been observed (see
Clearances -page 7);
b. Tip angle of heater does not exceed 30 degrees
(see Correct Mounting -page 12);
c. Gas line is properly connected and there are no
leaks (see Gas Piping -page 8);
d. Make sure 24 VAC is properly connected to the
heater. Applying 120 VAC to the heater will
damage the switch and other heater controls
2. Start Heater;
a. Turn ON manual gas valve.
b. Set switch to the high setting for the first 5
minutes.
c. If heater locks out, switch to OFF to RESET
Heater and repeat start up sequence.
d. If the heater locks out several timesthere may still
be air in the gas line.
