This heater is designed and approved for use as a construction heater under ANSI Z83.7 2000 and CSA 2.14 2000 Gas Fired Construction Heaters We cannot anticipate every use which may be made of our heaters. CHECK WITH YOU LOCAL FIRE SAFETY AUTHORITY IF YOU HAVE QUESTIONS ABOUT APPLICATIONS. Other standards govern the use of fuel gases and heat producing products in specific applications. Your local authority can advise you about these. SPECIFICATIONS Model …………………………………………………….
INSTALLATION: The installation of this heater for use with natural gas shall conform with local codes or, in the absence of codes, with the National Fuel Gas Code ANSI Z223.1/NFPA 54 and the Natural Gas and Propane Installation Code, CSA B149.1.
PRESSURES: MAXIMUM INLET PRESSURES: LP: NG: 14.0 IN. WC. 14.0 IN. WC. MINIMUM INLET PRESSURES: LP: NG: 11.0 IN. WC. 9.0 IN. WC. This heater must be supplied by pressures indicated on the approval label. Over pressure may cause controls to fail. DO NOT supply this unit with more than ½ psig (14.0 in. W.C.) Note: A second stage regulator must be installed if the supply pressure exceeds ½ psig. FUEL: This heater will operate on propane or natural gas.
MAINTENANCE: 1. Every construction heater should be inspected before each use, and at least annually by a qualified service person. 2. The hose assembly shall be visually inspected prior to each use of the heater. If it is evident there is excessive abrasion or wear, or the hose is cut, it must be replaced prior to the heater being put into operation. The replacement hose assembly shall be that specified by the manufacturer. 3.
START UP INSTRUCTIONS: 1. Set fuel selector valve according to gas supply to be used. 2. Connect construction heater to gas supply with approved hose assembly. 3. Plug the electrical cord into a 20 amp supply. 4. Open all gas supply valves. 5. Depress the main switch to the “START” position. The fan will start and the burner should ignite. Release switch to “RUN” position. 6. Set the Thermostat to the desired temperature. 7. If heater fails to ignite after 3 attempts call your supplier for service.

F-1500T TROUBLESHOOTING ANALYSIS PROBLEM Heater will not light POSSIBLE CAUSES REMEDY Air switch improperly set - use centre adjusting screw to set air switch. Turn clockwise to increase sensitivity, turn counter clockwise to decrease sensitivity. Blockage in copper inlet tubes - disconnect tubes from air switch. Use high pressure air to clean any debris that may block airflow.
Faulty switch - replace switch Gas supply - ensure required gas supply pressures are supplied to the heater (see approval label) Solenoid - ensure solenoid is energized (use volt meter) - ensure plunger in solenoid is being activated (use manometer at test point after solenoid) Spark Plug - ensure gap in spark plug is approx.
Heater will not remain lit after start up Thermostat - ensure thermostat is calling for heat Faulty flamerod wire - check flamerod wire for any damage. Replace if necessary. Faulty flamerod -ensure connections are secure. Replace flamerod if necessary.
Electrical Ignition board - check ground wire for proper connection - check polarity of extension cord compared to polarity of plug on the heater - replace faulty ignition board Thermostat - ensure thermostat is calling for heat All components - before replacing any component, all connections must be checked to ensure electrical circuit is complete. (use volt meter and enclosed wiring diagram).
