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 property damage, injury or death. Refer to Section 13 WARNING Gas Connection Improper installation, connection, or adjustment can result in property damage, toxic gases, asphyxiation, injury or death.
WARNING Tube “GLOW” It is a normal condition that the combustion tube (1st tube) can appear to “glow red”. For inputs up to 150,000 Btuh, the top surface of the tube can appear red where heat is trapped between the reflector and the tube. The stainless steel tube used for inputs 175,000 and greater can appear to entirely glow red. The tube material is designed into the heater because it can withstand the high temperature of combustion, and the “red glow” is a normal occurrence.

WARNING 12. 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.
heaters must be controlled by a single common thermostat or “ON/OFF” switch. Install a minimum 36 inch (91 cm) length of minimum 26 gauge single walled 4” (10 cm) diameter vent pipe on the system, and a minimum 12 inch (30 cm) before any Tee or Elbow. Seal all vent connections with high temperature sealant. Vent connections must be secured with three (3) #8 sheet metal screws uniformly spaced around the circumference of the pipe. Any horizontal vent pipe must slope approx.
Use approved 4" (10 cm) (JA-0528-XX) or 6" (15 cm) (JA-0529-XX) horizontal wall vent terminal OR a high-wind termination cap approved by a recognized certification agency 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. 20). Ensure flue gases are directed away from the structure to protect building materials from degradation by the exhausted flue gases.
VERTICAL VENT THROUGH THE ROOF: FIGURE 22 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’.
13. COMBUSTION AIR DUCTING Do not install filters on the combustion air intake. Ensure adequate clearance around the air intake to allow sufficient combustion air supply to the heater. An opening is located on the top surface of the burner housing for combustion air . Ensure adequate clearance around this opening to allow sufficient combustion air supply to the heater. Combustion air duct must be constructed of noncombustible material.
14. GAS SUPPLY - HEATER EXPANSION - GAS CONNECTION The gas supply must be installed to the heater using: USA: an approved Stainless Steel Flexible Gas Connector certified for use on an infrared radiant tube heater (ANSI Z21.24 CSA 6.10); CANADA: an approved Type 1 Hose Gas Connector (CAN/CGA 8.1). The heater must be isolated from the gas supply piping system by closing its individual manual shut off valve (field supplied) during any pressure testing of the gas supply piping system.
NOTE: Access to the manifold pressure test port is on the top of the valve. A 3/16" Allen Wrench is necessary to check this. When checking or setting the manifold pressure, a water manometer should be used. Gauges which measure in ounces per square inch or pounds per square inch are not accurate enough to properly measure or set the pressure. WARNING THIS HEATER WILL EXPAND IN LENGTH AS IT HEATS UP. It is a normal condition that during heat-up and cool-down a tube heater will expand and contract.
FIGURE 23 ORIENTATION OF FLEXIBLE GAS CONNECTOR The flexible gas connector MUST be installed in the orientation shown below as required by national installation codes and by the certification standard of this heater. This orientation protects the flexible gas connector from damage due to movement during heater expansion. It is the responsibility of the installer to ensure correct installation of the flexible gas supply.
