SAFETY INFORMATION Continued 2 099597 ! WARNINGS Propane Gas: Propane gas is odorless. An odor-making agent is added to propane gas. The odor helps you detect a propane gas leak. However, the odor added to propane gas may fade. Propane gas may be present even though no odor exists. Make certain you read and understand all warnings. Keep this manual for reference. It is your guide to safe and proper operation of this heater. • Install and use heater with care. Follow all local ordinances and codes.
PRODUCT IDENTIFICATION Hot Air Outlet (Front) Shell Handle Motor Fan Guard Heater Base Piezo Ignitor Button Automatic Control Valve Button Inlet Connector Power Cord Hose /Regulator Assembly Figure 1 - 35,000 BTU/Hr Model UNPACKING 1. Remove all packing items applied to heater for shipment. Keep plastic cover caps (attached to inlet connector and hose/regulator assembly) for storage. 2. Remove all items from carton. 3. Check all items for shipping damage.
The Fuel System: The hose/regulator assembly attaches to the propane gas supply. This provides fuel to the heater. THEORY OF OPERATION The Air System: The motor turns the fan. The fan pushes air into and around the combustion chamber. This air is heated and provides a stream of clean, hot air. The Ignition System: The piezo ignitor lights the burner. The Automatic Control System: This system causes the heater to shut down if the flame goes out.
INSTALLATION ! WARNING Review and understand the warnings in the Safety Information Section, pages 2 and 3. They are needed to safely operate this heater. Follow all local codes when using this heater. ! WARNING Test all gas piping and connections for leaks after installation or servicing. Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once. 1. Provide propane supply system (see Propane Supply, page 5).
4. Open propane supply valve on propane tank(s) slowly. Note: If not opened slowly, excess-flow check valve on propane tank may stop gas flow. If this happens, close propane supply valve and open again slowly. 5. Check all connections for leaks. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak that must be corrected. ! WARNING Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints.
OPERATION Continued 5. Open propane supply valve on propane tank(s) slowly. Note: If not opened slowly, excess-flow check valve on propane tank may stop gas flow. If this happens, close propane supply valve and open again slowly. ! WARNING Be sure motor and fan are running before pushing in automatic control valve button. Flames could flash outside heater if motor and fan are not running. 6. Push in and hold automatic control valve button (see Figure 5). Push piezo ignitor button (see Figure 5).
STORAGE ! CAUTION Disconnect heater from propane supply tank(s). 1. Store propane tank(s) in safe manner.
