WARNING Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or death. Read and understand this installation and operation manual thoroughly prior to assembly, installation, operation or service to this appliance. This heater must be installed and serviced only by a trained gas service technician. Do not store or use gasoline or other flammable vapours and liquids in the vicinity of this or any other gas fired appliance.
WARNING Heater Expansion It is a normal condition that during heat-up and cool-down a tube heater will expand and contract. Allowances for heater expansion must be made in the gas connection, venting and combustion air ducting. Improper installation, alteration, or adjustment can result in WARNING Gas Connection Improper installation, connection, or adjustment can result in property damage, toxic gases, asphyxiation, injury or death.
WARNING Clearance to combustibles Location of flammable or explosive objects, liquids or vapors close to the heater may cause fire or explosion and result in property damage, injury or death. Do not use, store or locate flammable or explosive objects, liquids or vapors in proximity of the heater. The clearance to combustible material represents the minimum distance that must be maintained between the outer heater surface and a nearby surface.
NOTE: A ‘PEEL & STICK’ SIGN IS SUPPLIED: USE AN INDELIBLE MARKER TO ENTER VALUES ON THE SIGN: ‘H’ = Calculate (instruction below) Sides of horizontal heater: ‘S’ = 24 inches (61 cm) Front of 30° Angle heater: ‘F’ = 36 inches (91.5 cm) Behind 30° Angle Heater ‘B’ = 24 inches (61 cm) POST THE SIGN ADJACENT TO THE HEATER THERMOSTAT OR IN A PROMINENT LOCATION. See next page for details.
It is the installer’s responsibility to ensure that building materials with a low heat tolerance which may degrade at lower temperatures are protected to prevent degradation. Examples of low heat tolerance materials include vinyl siding, fabrics, some plastics, filmy materials, some coatings and laminated finishes, etc. VENT END CLEARANCE: Clearances from the vent pipe are determined by local or national installation codes, but must not be less than 6 inches (15 cm).
1. LABOR REQUIRMENTS Two persons are required to safely install this equipment. SHARP EDGES - Wear gloves and other required safety protection. 2. INSTALLATION IN COMMERCIAL AIRCRAFT HANGARS Low intensity radiant tube heaters are suitable for use in aircraft hangars when installed in accordance with the latest edition of the Standard for Aircraft Hangars, ANSI/NFPA No 409 in the USA, or the Canadian Natural Gas and Propane Installation Code, B149.1. A.
WARNING Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or death. Read and understand this installation and operation manual thoroughly prior to assembly, installation, operation or service to this appliance. This heater must be installed and serviced only by a trained gas service technician. Do not store or use gasoline or other flammable vapours and liquids in the vicinity of this or any other gas fired appliance.
Ensure adequate clearance around the air intake at the burner to allow sufficient combustion air supply to the heater. Proximity of lights, sprinkler heads, overhead doors, storage areas, gas and electrical lines, parked vehicles, cranes and any other possible obstruction or hazard must be evaluated. 6A. SERVICE CLEARANCE: The lower ‘jaw’ of the burner cabinet swings down to provide convenient service access to burner components.
IMPORTANT: Single or multiple heater placement must be such that continuous operation of heaters will not cause combustible material or materials in storage to reach a temperature in excess of ambient temperature plus 90F° (50C°). It is the installer’s responsibility to ensure that building materials with a low heat tolerance which may degrade at lower temperatures are protected to prevent degradation.
FIGURE 3 TYPICAL MOUNTING HARDWARE HOOK OR EYE BOLT THROUGH HOLE IN BEAM BEAM CLAMP WITH HOOK OR EYE HOOK OR EYE SCREW PIPE RING OR CLEVIS HANGER BAR-JOIST CLAMP NOTE: It is the installer’s responsibility to ensure that mounting hardware and fastening to structure are of sufficient strength and integrity to support the system.
FIGURE 4 TYPICAL SUSPENSION Use all four suspension points + a chain at burner eye hook. Hardware capable of supporting minimum 100 lbs (45 kg) at each suspension point. For seismic and high wind restraint see ) cm Sections 8-A & 8-B.
FIGURE 6 P40U MINIMUM CLEARANCES TO COMBUSTIBLES It is the installer’s responsibility to ensure that building materials with a low heat tolerance which may degrade at lower temperatures are protected to prevent degradation. Examples of low heat tolerance materials include vinyl siding, fabrics, some plastics, filmy materials, coatings, laminated surfaces, etc. Turbulators: The system is assembled at the factory with turbulators inside the tube.
8-A SEISMIC RESTRAINT - LATERAL AND LONGITUDINAL PLANES FIGURE 7 In areas prone to earthquake, or as specified on a project, install lateral and longitudinal seismic restraints as indicated in Figure 11. If the heater location can be impacted by wind (aircraft hangars, etc) refer to High Wind Restraint section 8-B below. These instructions indicate attachment of suspension and restraint hardware to the heater.
WARNING 9. FLUE VENTING Inadequate venting of a heater may result in asphyxiation, carbon monoxide poisoning, injury or death. This heater may use a vent connection or indirect venting system to remove products of combustion from the space. Seal all vent connections with high temperature sealant. Venting must be in accordance with all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in USA; B149.1 in Canada) and as indicated below in this manual.
need to be equidistant to the vent Tee, but must comply to requirements below. The two heaters must be controlled by a single common thermostat or “ON/OFF” switch. A minimum 12 inch (30 cm) length of minimum 26 gauge single walled 4” (10 cm) diameter vent pipe is to be installed on the swaged end of the tube before any Tee or Elbow is fitted. Seal all vent connections with high temperature sealant.
Termination Cap Options: Use the approved 4" (10 cm) (JA-0528-XX) or 6" (15 cm) (JA-0529-XX) horizontal wall vent terminal (see FIGURE 20 for applicable clearances) OR a high-wind termination cap approved by a recognized certification agency (see clearance notes below) Install any termination cap a minimum of 18 inches (45 cm) from the outside wall to the inside edge of terminal opening to alleviate back pressure caused by turbulent wind conditions (See Fig. 19).
VERTICAL VENT THROUGH THE ROOF: It is the sole responsibility of the installer to adhere to all current local codes and/or ANSI Z223.1 / CSA.B149.1 latest editions for all venting requirements, and practices. Use an approved ‘B-vent’ termination cap as supplied by the manufacturer of the approved ‘B-vent’.
Optional 4 inch intake terminals are available for this heater: Part number: JS-0532-VC Wall mount, bird-screened fresh air intake duct hood Part number: JS-0530-XX Roof cap Ensure adequate clearance around the air intake to allow sufficient combustion air supply to the heater. If drawing fresh air from outside, it is recommended that any single wall pipe containing cold air be insulated to prevent or reduce condensation on the pipe.
DO NOT use pressure greater than 1/2 psig to pressure check the heater. During any pressure testing of the gas piping system each heater must be isolated from the piping system by closing its individual manual shut off valve (field supplied) . IMPORTANT: Minimum supply line pressure at the inlet to the heater regulator must not be lower than 5.0 inches of water column pressure for natural gas. The supply gas pressure must be checked with all heaters in operation.
Orientation of Flexible Gas Connector (continued) FIGURE 13 12. GAS CONVERSION WARNING: Gas conversion must only be performed by a trained gas service technician. Do not convert heater to alternate gas without using one of the kits listed below. Property damage, injury or death could result. Standard production of this model heater is for use with natural gas.
