Maximum Pressure 1/2 psig 1/2 psig
Minimum Pressure 6″ W.C. 11″ W.C.
Manifold Pressure 5″ W.C. 10″ W.C.
It is important 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 Combustibles” are maintained.

OPTIONAL MOUNTING KIT (#12006): Optional Mounting Kit is available from your heater supplier. 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

 

 Model Input BTUH Side In Rear In Ceiling In Below In Mtg.Angle
S25 25,000 24″ 12″ 9″ 48″ HORZ
S34 34,000 24″ 17″ 13″ 48″ HORIZ
*S25 25,000 24″ 8″ 14″ 48″ 30 deg MAX
S34 34,000 24″ 8″ 18″ 48″ 30 deg MAX
Above clearances apply to models on either natural or LP gas. *Model S25 for LP gas for use in horizontal position only.

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 soffit.

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 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, sign shall be posted to specify the maximum permissible stacking height to maintain required clearances from the heater to combustible materials.

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.

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 16-gauge 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.

! WARNING
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 requirement must be observed.

Electrical

Provide only 24 VAC with a NEC Class 2 transformer to the heaters. Each heater requires approximately 20 VA or 0.8 amps. When multiple heaters are connected to one transformer, the transformer must be sized to accommodate the entire load. A transformer must never be located inside the heater control compartment.

Control wire used to electrically connect one or more heaters together must have adequate capacity and insulation temperature rating for the total connected load. Use at least 18 GA wire up to 50 feet from heater to transformer or wall switch. Use a minimum of 16 GA wire for over 50 feet distance.

If any of the original wire supplied with the appliance must be replaced, it must be replaced with wiring material having a temperature rating of at least 105 degrees Centigrade.

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 opening for removing the flue products shall be above the level of the heaters.
    3. Heater ventilation must comply with state and local codes.
  2. Before turning on the manual gas valve to the heater verify that the control system is working properly.
  3. Apply 24 VAC to the heater.
  4. There should be an audible click and the spark initiates at the pilot.
  5. With the gas turned off the heater should turn “OFF” or lockout in within 10 seconds ( Synetek controls will cycle “ON” and “OFF” 3 times before lockout.
  6. Turn the electrical switch “OFF”.
  7. Turn “ON” the manual gas valve to the heater.
  8. Check for leaks using soapy water at all gas connections and joints. NEVER use a flame to check for leaks.
  9. Apply 24 VAC to heater.
  10. Check for pilot ignition. A smooth flame front should roll down the length of the infrared burner. Flame should stabilize on the ceramic surface.
  11. The ceramics portion of the infrared burner should turn RED within 5 minutes (this may be difficult to see in bright sunlight).

Gas Piping

  1. A minimum pipe size of 1/2″ is required for inlet piping. A 1/2″ leaver handled shut-off gas cock should be installed within 6 feet of the appliance for servicing the unit.
  2. Check with local and state plumbing and heating codes regarding sizing of the 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 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 1/2 psig, consult the factory or your local representative.
  7. Installation of 1/8″ N.P.T. plugged tapping, accessible for test gage connections, is required upstream of the gas supply connection to the heater.
