Code ANSI Z223.1/NFPA54 or the Natural Gas and Propane Installation Code CSA B149.1. Heaters shall be
installed by a licensed contractor or licensed installer. Clearances to combustibles as outlined in this manual
should always be observed. In areas used for storage of combustible materials where they may be stacked
below the heater, NFPA54 requires that the installer must post signs that will “specify the maximum permissible
stacking height to maintain the required clearances from the heater to combustibles.”
Every heater shall be located with respect to building construction and other equipment so as to permit access
to the heater. Each installer shall use quality installation practices when locating the heater and must give
consideration to clearances to combustible materials, vehicles parked below, lights, overhead doors, storage
areas with stacked materials, sprinkler heads, gas and electrical lines and any other possible obstructions or
hazards. Consideration also must be given to service accessibility.
The heater, when installed in aircraft hangars and public garages, must be installed in accordance with
ANSI/NFPA 409-latest edition (Standard for Aircraft Hangars), ANSI/NFPA 88a-latest edition (Standard for
Parking Structures), and ANSI/NFPA 88b-latest edition (Standard for Repair Garages) with the following
clearances:
a. At least 10 feet above the upper surfaces of wings or engine enclosures of the highest aircraft that may be
housed in the hangar and at least 8 feet above the floor in shops, offices, and other sections of hangars
communicating with aircraft storage or service areas.

b. For installation in public garages or aircraft hangars, the minimum clearances from the bottom of the
infrared heater to the upper surface of the highest aircraft or vehicle shall be 50 percent greater than the
certified minimum clearance, but the clearance shall not be less than 8 feet.
Although these heaters may be used in many applications other than space heating (e.g., process heating),
SunStar will not recognize the warranty for any use other than space heating.
This heater is for Indoor Installation and Covered Patio Installation only and can be used in either Vented or
Unvented mode. The term Unvented actually means Indirect Vented. While the products of combustion are
expelled into the building, national codes require ventilation in the building to dilute these products of
combustion. This ventilation may be provided by gravity or mechanical means.

9.0) TYPICAL SUSPENSION METHODS
SUSPENSION HAZARD
Burner must be secured to the mounting flange with nuts.
All materials used to suspend the heater must have a minimum working load
of 115 lbs.
All S Hooks must be crimped closed.
Never use the heater to support a ladder or other access equipment.
Failure to do so may result in death, serious injury or property damage.
Various means of suspending the heater can be used. See the following drawings for typical examples.
1. Use only noncombustible materials for suspending hangers and brackets.
2. A minimum No. 2 chain with a working load limit of 115 lbs. is required.
3. Turnbuckles can be used with chains to allow leveling of the heater. All “S” hooks and eye bolts must be
manually crimped closed by the installer.
4. When using rigid means for heater suspension (rod, flat bar, etc.) provide sufficient lengths or swing joints to
compensate for expansion. See Figures b and c.
5. Heaters subject to vibration must be provided with vibration isolating hangers.
6. Heaters must not be supported by gas or electric supply lines and must be suspended from a permanent
structure with adequate load capacity.
SunStar recommends that the tube sections be suspended using chains with turnbuckles. This will allow slight
adjustments after assembly and heater expansion/ contraction during operation.
If a “trapeze” method is used for tube support/hanger brackets (shown below), the minimum chain length for the
two connecting chains is 36” to minimize any vibration that might be generated by the draft inducer assembly. If
these chains must be less than 36”, then do not use the trapeze method and, instead, use individual chains on
each tube support/hanger bracket.

2. Lift the tube section and suspend it into place. When lifting, caution should be used to avoid damaging the
assembly. Make sure that the long axis of heater is level.
3. Assembly the reflector onto the tube section. Leave 3” space between the tube flange and the reflector for
later mounting of control box and draft inducer.
4. Place the flanges of the control end reflector flush with the end of the first reflector. Secure by sliding speed
clips onto reflector edges. Evenly space 6 speed clips on sides and top of reflectors to provide a snug fit.
Place foot end reflector on the opposite end of the reflector and secure as above.

1. When venting the heater to outside of building through a roof, use single-wall metal pipe. This is to be
constructed of galvanized sheet metal or other approved noncombustible corrosion-resistant material as
allowed by state or local codes.
2. A vent passing through a combustible roof shall extend through an approved clearance roof thimble. Double-
wall, Type B vent must be used for the portion of the vent system which passes through the combustible roof.
An approved vent cap must be attached to end of the flue.
3. The maximum equivalent length of vent pipe should be carefully observed. A safety switch in the heater is
designed to shut the heater off before excessive flue restriction causes bad combustion. Refer to the Vent
Sizing Table for maximum vent lengths and vent pipe diameter.
• Minimum Equivalent Length = 5 ft. of pipe
• Maximum Equivalent Length = 75 ft. of pipe
Use the following correction factors to obtain the equivalent length:
• Subtract 15 ft. if the run is horizontal.
• Subtract 10 ft. for an approved vent cap.
• Subtract 10 ft. for each elbow beyond 15 ft. from the heater.
• Subtract 15 ft. for each elbow within 15 ft. of the heater.
4. Joints between sections of piping shall be fastened by sheet metal screws or other approved means and
should be sealed to prevent leakage of flue gas into building. For Residential Installations:
the length of the piping and the joints between sections of piping should be sealed to prevent a potential
leakage of flue gas into building. Use 100% RTV Silicone Rubber Adhesive sealant suitable for 500 ºF. For
Commercial and Industrial Installations:
Commercial and Industrial Installations: Use aluminum or Teflon tape suitable for 550ºF (3M Company
Commercial and Industrial Installations:Commercial and Industrial Installations:
tapes 433 or 363) or RTV silicone sealant.
5. Avoid locating elbows in the first 5’ of vent pipe whenever possible. Limit to (2) 90° elbows. When vent pipe
is in a horizontal run, it must have 1/4 inch per foot rise.
6. All portions of the vent pipe shall be supported to prevent from sagging (6’ spacing is recommended).
7. When the vent pipe passes through areas where the ambient temperature is likely to induce condensation
of the flue gases, the vent pipe should be insulated and a condensation drain should be provided.
8. Minimum clearance for single-wall flue pipe to combustible material shall be 6 inches. This may be reduced
when the combustible material is protected as specified in the National Fuel Gas Code or the authority
having jurisdiction.
9. Single-wall metal pipe shall not originate in any unoccupied attic or concealed space and shall not pass
through any attic, inside wall or concealed space, or through any floor. For the installation of a single-wall

1. For horizontal venting, the vent lengths may be as follows:
• Minimum Equivalent Length = 5 ft. of pipe
• Maximum Equivalent Length = 75 ft. of pipe
Use the following correction factors to obtain the equivalent length:
• Subtract 15 ft. if the run is horizontal.
• Subtract 10 ft. for an approved vent cap.
• Subtract 10 ft. for each elbow beyond 15 ft. from the heater.
• Subtract 15 ft. for each elbow within 15 ft. of the heater.
NOTE:
NOTE: To minimize problems associated with condensation in long horizontal runs, vent pipe can be insulated.
NOTE:NOTE:
2. The horizontal venting system approved with this heater consists of the following components: one 4” Vent
Cap (Part #30297040, one 4” x 36” ‘B’ Vent Section (Part #30496360), and one 4” Wall Thimble (Part
#30500040). Please specify the appropriate number of 24-inch sections of single-wall vent pipe and elbows
when ordering: Vent Pipe (Part #30497240), 90º Elbows (Part #30498040), and 45º Elbows (Part
#30499040).
3. Avoid locating elbows in the first 5 feet of vent pipe whenever possible. Limit the quantity of 90º elbows to
two (2). When vent pipe is in a horizontal run, it must be pitched downward
downward 1/4 inch per foot towards the
downwarddownward
vent terminal. The heater must be installed level.
4. A minimum clearance of 18 inches must be maintained between the outside wall and vent cap (18”
clearance will provide stability under high wind conditions).
5. The horizontal venting system shall not terminate:
•Less than 4 ft. (1.2m) below, 4 ft. (1.2m) horizontally from or 1 ft. (30cm) above any door, operable
window or gravity air inlet into any building. The bottom of the vent terminal shall be located at least 7 ft.
(2.1m) above grade or above snow accumulation level as determined by local codes.
• Less than 3 ft. (0.9m) from a combustion air inlet.
• Less than 3 ft. (0.9m) from any other building opening or any gas service regulator.
• Less than 7 ft. (2.1m) above public walkways.
• Directly over areas where condensate or vapor could create a nuisance or hazard or be harmful to the
operation of gas utility meters, regulators, relief valves, or other equipment. Building materials should
be protected from flue gases and condensate.
•Less than 12” (0.30m) when directly below a combustible overhang.
6. In regions of the country where prevailing winds are consistently higher than 40 mph, it may be necessary to
terminate the vent system above the roof level.

(CONNECTIONS INTO A COMMON VENT OR MANIFOLD)
Requirements for venting of multiple heaters are the same as described for SINGLE HEATER VENTING
follows:
1. The common vent size and total vent height is normally determined by the number of heaters per common
vent, length of horizontal connector runs, and connector rise. Connector lengths should be as short as
possible and have a minimum 1/4 inch per foot rise. Without regard to connector rise and total vent height
due to many possible venting configurations, the following should be observed:
•Common vent pipe & vent connector diameter should be no less than that shown in the following Vent
Sizing Table.

(Remove)
The combustion air inlet should
be not less than 3 ft. (0.9m),
either vertically or horizontally,
from the flue vent termination.
15.0) AIR FOR COMBUSTION
If indoor combustion air is to be supplied for a tightly enclosed area, one square inch of free area opening shall
be provided below the heater for each 1,000 Btu/hr per hour of heater input. When outside air is used, the
opening below the heater shall be one square inch of free area for each 4,000 Btu/hr of heater input. In
contaminated atmospheres or high humidity areas, optional outside air for combustion is recommended.
Adequate clearances around the perforated fresh air plate must be maintained at all times. In larger open areas
of buildings, infiltration normally is adequate to provide air for combustion.
15.1) DIRECT OUTSIDE AIR FOR COMBUSTION
Outside combustion air should be supplied directly to the heater when the building is subject to negative
pressure, or when contaminants or high humidity are present in the building air. These contaminants include
paints, solvents, corrosive vapors or any other foreign particles that may cause damage to the heater or result in
poor combustion.
Outside combustion air can be brought directly to the heater by a 4” diameter duct less than 50 ft. long or
equivalent (see table in Section 14.0) based on selected model and heat exchanger lengths). This is attached to
the 4” diameter starting collar. The starting collar is fitted to the top of the control box cabinet after first

outside combustion air inlet pipe. The combustion air inlet should be not less than 3 ft. (0.9m), either vertically
or horizontally, from the flue vent termination. The air intake terminal must be located not less than 1 ft. (30cm)
above grade. It is good installation practice to supply combustion air from the same pressure zone as the vent
outlet. Avoid bringing combustion air to the heater from an attic space. There is no guarantee that adequate
combustion air will be supplied.
In colder climates, where necessary, insulate the outside combustion air duct. Avoid locating the outside
combustion air duct directly above the control box. Provide a capped cleanout T as necessary. In high humidity
applications, the control box should be sealed with silicone sealer.
In multiple heater applications

16.0) LIGHTING AND SHUTDOWN INSTRUCTIONS
Never operate the heater with the access panel open or removed.
The access panel must be closed tightly during operation.
Failure to do so may result in death, serious injury or property
damage.
1. Turn on the gas and electrical supply. Rotate the gas valve knob counter-clockwise to the “ON” position.
2. Set the thermostat to call for heat. The blower motor will energize.
3. Ignition should occur after the 30-second air pre-purge.
4. If ignition fails, the unit will spark for approximately 21 seconds and go into safety lockout. Turn the
thermostat (power) off for 60 seconds to take the system out of lockout.
5. If the heater does not light, manually reset the thermostat or shut off power completely for 5 minutes before
attempting to relight.
6. To permanently shut down the heater, rotate the gas valve knob clockwise to the “OFF” position and turn
off the gas and electrical supply.
