1.0) SAFETY This heater is a self-contained two stage infrared radiant tube heater. Safety information required during installation and operation of this heater is provided in this manual and the labels on the product. The installation, service and maintenance of this heater must be performed by a contractor qualified in the installation and service of gas fired heating equipment.
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.
4.0) MINIMUM CLEARANCES TO COMBUSTIBLES Combustible material must be located outside the clearance dimensions listed. Failure to do so may result in death, serious injury or property damage. Minimum clearances to combustibles shall be measured from the outer surfaces as shown in the following diagram: End End Ceiling * Ceiling Front Side Below Side Rear Below 45° Angle (Maximum) Horizontal MINIMUM CLEARANCES TO COMBUSTIBLES Model No.

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.
10.0) ASSEMBLY OF TUBE SECTIONS CUT HAZARD Sheet metal parts, particularly reflectors and vent have sharp edges. Always use gloves when handling. Failure to do so may result in death, serious injury or property damage. During field assembly of the heater body sections, the recommended procedure is as follows: 1. Before hanging heater sections, first determine the actual layout of the system (see Sections 7.0 & 8.0 for details).

This must be installed closest to the burner. Failure to do so may result in deterioration of the turbulator material and invalidate the warranty. ADDING REFLECTORS 1. Slide the reflectors on the tube support/hanger brackets and through the wire hangers. 2.
11.0) ADDING OPTIONAL 90º ELBOW (PTS ONLY) 1. The optional 90º elbow must be located a minimum of 10 ft. after the control box. 2. Hang the body sections in a 90º ("L") shaped pattern. Allow spacing for the elbow. The distance from one end of the elbow to the centerline of the opposite leg is 13" as shown. 3. Join the tube ends of the body sections and the elbow together and secure with tube couplings as described in Section 10.1. Tube Coupling 90 Deg.
11.2) ADDING 180°U-Bend (PTU ONLY) 1. Hang body sections parallel with each other. The centerline distance from tube at each body section should be 18” as shown. 2. Join tube ends of body sections and the U-Bend together and secure with tube couplings as described in Section 10.1.

12.0) ATTACHING BURNER BOX ASSEMBLY 1. Attach the burner box and gasket to end of tube flange and secure with 1/4-20 locknuts. 2. Assemble the optional end reflector flush with the end of the main body reflector. Secure by sliding speed clips onto the reflector edges. Evenly space the speed clips on the sides (one each side) and top (two required) of the reflectors to provide a snug fit. Leave a 3" space between the end reflector and the burner box assembly. 3.
12.1) CONNECTING THE TISS SYSTEM Description: The TISS (Tube Integrity Safety System) is designed to shut the main burner off in the event that a burnout occurs in the first 10ft. section of firing tube. Note: When replacing the firing tube a new TISS wire assembly PN 44176010 must also be installed. Instructions: 1. Make sure that the gap between the burner box and end of reflector is 3” and the reflector is securely attached to the reflector support bracket. Make adjustments if necessary.
3. Hold the spring retainer clamp and pull the TISS wire assembly to end of reflector at overlap joint. Slide spring retainer clamp over end of reflector as shown. Step 3 Thimble End View Spring Retainer Clamp Spring Wire & Sleeving Assembly TISS Wire Assembly PN 44176000 4. After attachment of the TISS, check to make sure that there is sufficient tension on the wire. Follow the diagram below to increase or decrease the tension as necessary. 1.
ANGLE MOUNTED HEATERS ONLY 5. If heaters are to be angle mounted, the TISS wire holder clamp must first be re-positioned as shown using the bottom hole pattern of the clamp. Follow procedures described earlier for all other adjustments. Re-position wire clamp using bottom hole pattern.
13.0) GAS CONNECTIONS AND REGULATIONS Tighten flexible gas hose and components securely. Flexible metal gas hoses must be installed without any twists or kinks in them. The hose will move during operation of the heater and it can crack if it is twisted. Failure to do so may result in death, serious injury or property damage. IMPORTANT BEFORE CONNECTING THE GAS TO THE HEATER 1. Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code (ANSI Z223.

14.0) INSTRUCTIONS FOR PRESSURE TEST GAUGE CONNECTION Never operate the heater with the access panel open or removed. The access panels must be closed tightly with all the necessary screws during operation. Failure to do so may result in death, serious injury or property damage. The access doors on either side of the burner must be securely fastened before operating the heater. DANGER FIRE HAZARD Never operate the heater with the access panel open or removed.

16.0) VENTING CARBON MONOXIDE HAZARD Heaters installed in an unvented mode require a minimum ventilation flow of 4 CFM per 1,000 Btu/hr of total installed capacity. In buildings with airborne contamination such as poultry houses the heater must be installed with fresh air for combustion. Failure to do so may result in death, serious injury, property damage or illness from Carbon Monoxide poisoning. A.
the flue gases, the vent pipe should be insulated and a condensation drain should be provided. 7. 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. 8. 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.

COMMON VENTING OF MULTIPLE HEATERS IN CONFINED SPACES IS PROHIBITED. If any heater connected to a common vent system for multiple heaters is found inoperative, the heater should be disconnected from the vent system and its entrance into the vent system capped. Multiple Heater Horizontal venting arrangement.
17.0) 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 of heater input. Adequate clearances around the air inlet screen must be maintained at all times. In larger open areas of buildings, infiltration normally is adequate to provide air for combustion. 17.
In multiple heater applications, the combustion air intake may be ducted individually or common ducted in the same configuration as shown for venting in Section 16.0. For combustion air intake duct sizing, please refer to the Vent Sizing Table and use the diameter indicated, based on the number of heaters per duct. SIDE VIEW (straight configuration) Flue vent termination must be 1 ft. (30 cm) higher than combustion air inlet cap. Combustion Air Intake 18.
19.0) SEQUENCE OF OPERATION The chart below shows the sequence of operation for the normal operating cycle of the PTS/PTU when connected to a permanent 120V power supply and the heater is turned on and off by a remote 24V thermostat. (Electrical connection diagram B).

21.0) CLEANING AND MAINTENANCE ELECTRIC SHOCK & EXPLOSION HAZARD Disconnect electrical power and gas supply before servicing. Failure to do so may result in death or serious injury. This heater must be cleaned and serviced annually by a qualified contractor before the start of each heating season and at any time excessive accumulation of dust and dirt is observed. Maximum heating efficiency and clean combustion will be maintained by keeping the heater clean.
