This is a direct-fired forced air construction heater for either indoor construction or outdoor use. Its intended use is primarily the temporary heating of buildings or structures under construction, alteration or repair. All the products of combustion generated by the heater are forced through the heater and released into the area being heated. This heater operates at approximately 98%+ combustion efficiency but still produces a small amount of carbon monoxide. Humans can tolerate small amounts of carbon monoxide for short periods. Carbon monoxide can build up in a heated space and failure to provide adequate ventilation could result in poisoning or death.

WARNING : NOT FOR USE WITH DUCT WORK.

INSTALLATION TO THE PROPANE GAS TANK

IMPORTANT : You must use a propane/LP gas supply cylinder that is compatible with the connection device provided with the hose and regulator.

1. Provide propane/LP supply system. Ensure that the valve on the cylinder is fully closed by turning the knob fully clockwise ( ). Ensure that the cylinder is fully upright for vapor withdrawl. (see size/capacity, page 7).
2. Connect hose to heater inlet. Tighten firmly using a wrench. You must use the regulator supplied with heater.
3. Connect fuel gas fitting hose/regulator assembly to propane LP tank(s).
   • For units with a POL fitting (see figure 1) turn fuel fitting counterclockwise into threads on tank. Tighten firmly using a wrench. Some models have a hand wheel that can be used to tighten the fitting. This hand wheel can be slid off of the nut so that a wrench can also be used to tighten the fitting. IMPORTANT: Position regulator so that hose leaving the regulator is in a horizontal position.
   • For units with a QCC fitting (see figure 2) turn QCC gas fitting clockwise onto threads on tank. Tighten firmly using your hand (DO NOT USE A WRENCH). IMPORTANT: Position regulator so that the regulator vent is pointing down toward the floor and the arrow on the regulator is visible.
4. Open propane/LP supply valve on propane/LP tank(s) slowly. NOTE: If not opened slowly, excess flow device in regulator may stop gas flow. If this happens, close propane/LP supply valve, wait one minute (or until you hear a click) and open again slowly.
