Dayton® Propane

Construction Heater

Propane Supply

Propane gas and propane tank(s) must be provided by the customer.

Use this heater only with a propane vapor withdrawal supply system. See Chapter 5 of the Standard for Storage and Handling of Liquefied Petroleum Gas, ANSI/NFPA 58 and/or CAN/CGA B149.2. Your local library or fire department will have this booklet.

This heater will operate with a 20-pound propane tank. However, you can only operate it in the LOW position during mildly cool weather. At higher heat settings or during colder weather, you must use larger tanks.

The amount of propane gas ready for use from propane tanks varies. Two factors decide this amount.

1.The amount of propane gas in tank(s)

2.The temperature of tank(s)

The chart below shows the minimum number of 100-pound tanks needed to run the heater. Connect tanks together with a manifold.

Less gas is vaporized at lower tempera- tures. Your local propane gas dealer will help you select the proper supply system.

Ventilation

Provide at least a 2.5-square-foot

opening of fresh, outside air while running heater. If proper fresh, outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventilation before running heater.

Installation

Review and understand the

warnings in the General Safety Infor- mation section. They are needed to safely operate this heater. Follow all local codes when using this heater.

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).

2.Connect fuel gas fitting on hose/ regulator assembly to propane tank(s). Turn fuel gas fitting counterclockwise into threads on tank. Tighten firmly using a wrench.

IMPORTANT: Tighten regulator with vent pointing down. Pointing vent down protects regulator from weather damage.

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, you may hear a click inside the regulator assembly. This is the check valve closing. To reset the excess- flow check valve, close propane supply valve and open it again slowly.

5. Check all connections for leaks.

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 that must be corrected. Correct all leaks at once.

6. Close propane supply valve.
