Basic Heater Operation
Sunpak® S34-TSH is a two-stage outdoor gas-fired
infrared heater which is operated with a wired switch. The
heater can be operated at a HIGH setting with an input 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 a three-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 Heater shown 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 correct this situation, press the OFF followed by HIGH.
Part No. 12052
TSH Switch with Light
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 gusty wind. To
restart the heater, first set the switch to OFF before
restarting the heater.
Although these heaters are designed for outdoor
installation and use, it is important that switches,
transformers or other operating controls 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 continuously whenever the heater is on.

Heater Layout and Design
SUNPAK will raise the comfort level 5-10º Fahrenheit outdoors.
terrace or roof top patio can cause damage to the heater.
ANGLE MOUNTING: Most applications of the
heaters to be located at least 8 feet above the floor.
Sunpak® heaters were specifically designed to provide
heated comfort in an outdoor environment. They have been
used on outdoor patios across the United States and
Canada for over 30 years. When properly integrated into a
patio design, Sunpak
comfort level 5º to 10º 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
vary greatly. As an outdoor rated heater it has pass ed bas ic
wind and rain tests. This does not mean the heater cannot
be damaged by the environment or when operated in very
windy conditions. For this 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
applied means that these 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 .

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 get warm.

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 mount the 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 necessary fresh air and ventilation for proper heater
operation (see ventilation of installation section).

MINIMUM CLEARANCE FROM COMBUSTIBLE MUST BE MAINTAINED (see chart on page 6 & 7)
The above coverage table was based on still breeze conditions.
Under windy conditions more heat will 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
SUNPAK®b heater may be angle-mounted to a
maximum of 30º to accommodate mounting the
heaters around the edges of the patio. Note that the
top clearance to combustibles increases when heater
is tipped from the horizontal.

Gas Supply
The gas inlet supply pressure and manifold pressures required
for each heater are listed below. For gas supply line pressures
in excess of ½ PSI, consult with your gas service provider or the
factory.
It is critical that the gas piping system be adequately sized
for all the gas appliances it serves.
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. Heaters should never be located in a ceiling recess or
any form of ceiling enclosure.
The stated clearance to combustible materials represents a
surface temperature of 90ºF (32ºC) above room temperature.
Building materials with a low heat tolerance (such as plastic,
vinyl siding, canvas, tri-ply, etc.) may be subject to degradation
at lower temperatures. It is the 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 specify the maximum permissible stacking
height to maintain required clearances from the heater to
combustible materials.
OPTIONAL MOUNTING KIT (#12006): Optional Mounting Kit is
included in some packages. Whether the mounting kit is used or
not, minimum clearance from combustibles must be observed as
follows:
WARNING: The clearances shown below are also applicable to
vehicles parked below heaters.

WARNING
requirement must be observed.
Gas Piping
Heater Mounting and Support
Heaters shall be mounted in a fixed position independent
of gas and electrical supply line. Hangers and brackets
shall be of noncombustible material.
Heaters subject to vibration shall be provided with
vibration isolating hangers.
Suitable materials for hanging infrared heaters are steel
pipe, steel channel, or fabricated hangers of at least 16gage material. Hanger and brackets must be secured with
adequate anchor to a secure structure using good building
practices. Additional bracing to protect against seismic
forces may be required in seismically active areas. Never
mount heaters to a moving object such as a trailer, motor
home, boat, etc.
Suspension Hazard
Mounting kits and hanging supports must
be able to withstand a minimum working
load of 75 lbs. (33 kg). Failure of the
supports can result in death.
Local codes regarding head clearance
Sunpak® Infrared Heaters
1. A minimum pipe size of ½” is required for inlet
piping. A ½” lever handled gas shut-off valve
should be installed within 6 feet of the appliance
for servicing and as emergency shutoff to the unit.
2. Check with local and state plumbing and heating
codes regarding sizing of gas lines.
3. All gas pipe connections to the heater(s) must be
sealed with a gas pipe compound resistant to
liquefied petroleum gases.
4. Installation of a drip leg or sediment trap in the gas
supply line going to each heater is required to
minimize the possibility of any loose scale or dirt
within the gas supply line from entering the
heater’s control system.
5. When checking for gas leaks, do not use an open
flame. Use a soap and water solution.
6. For gas supply line pressures in excess of ½ PSI,
consult the factory or your local representative.
7. Installation of 1/8” N.P.T. plugged tap accessible
for test gage connections is required upstream of
the gas supply connections 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 transformer always allow for a current
draw of 20 VA per heater. A 24V – 40VA
transformer will 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 105 degrees Centigrade.

Sunpak® Infrared Heaters
Ventilation
1. It is required that areas above the heater be
properly vented to allow for necessary combustion
air and removal of combustion gases.
2. Heaters shall be provided with natural or
mechanical means to supply and exhaust at least
4 cfm per 1,000 BTU per hour of heater input.
Exhaust openings for removing the flue products
shall be above the level of the heaters.
3. Heater ventilation must comply with 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 heater make 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 times there may still
be air in the gas line.
NOTE: Some white smoke may appear
during or just after the initial start-up of the
heater. White smoke will dissipate with
proceeding use. This is normal due to some
residual lubrication on a new heater
Regular Service and Maintenance
Over time, particularly during long periods of nonuse, the heater can accumulate dirt and debris in
and around the pilot and the burner. Routine
maintenance should be performed at least once a
year by a qualified service agency to insure the
heater is operating properly. More frequent
service may be required for heaters located near
waterfronts. If local service is not available call
your natural gas or propane supplier.
