WARNINGS

PropaneGas:Propanegasisodorless.Anodor-makingagentisaddedtopropane

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.

Makecertainyoureadandunderstandallwarnings.Keepthismanualforreference.

It is your guide to safe and proper operation of this heater.

• Install and use heater with care. Follow all local ordinances and codes. In the

absence of local ordinances and codes, refer to the Standard for Storage and

Handling of Liquefied Petroleum Gas, ANSI/NFPA 58 and the Natural Gas

Installation Code, CAN/CGA B149.2. This instructs on the safe storage and

handling of propane gases.

• Use only the hose and factory preset regulator provided with the heater.

• Use only propane gas set up for vapor withdrawal.

• Provide adequate ventilation. Before using heater, provide at least a 2.5-square-

foot opening of fresh, outside air. This heater produces carbon monoxide, which

is listed by the State of California as a reproductive toxin under Proposition 65.

• For indoor use only. Do not use heater outdoors.

• Do not use heater in occupied dwellings or in living or sleeping quarters.

• Do not use heater below ground level. Propane gas is heavier than air. If a leak

occurs, propane gas will sink to the lowest possible level.

• Keep appliance area clear and free from combustible materials, gasoline, paint

thinner, and other flammable vapors and liquids. Do not use heater in areas

with high dust content.

• Minimum heater clearances from combustibles:

Sides: 4 Ft. Top: 6 Ft.

• Keep heater at least six feet from propane tank(s). Do not point heater at

propane tank(s) within 20 feet.

• Keep propane tank(s) below 100°F.

• Check heater for damage before each use. Do not use a damaged heater.

• Check hose before each use of heater. If highly worn or cut, replace before

using heater.

• Locate heater on stable and level surface if heater is hot or operating.

• Not intended for use on finished floors.

• Never block air inlet (bottom) or air outlet (top) of heater.

• Keep heater away from strong drafts, water spray, rain, or dripping water.

• Do not leave heater unattended.

• Keep children and animals away from heater.

• Never move, handle, or service a hot, operating, or plugged-in heater. Severe

burns may result. Wait 20 minutes after turning heater off.

• To prevent injury, wear gloves when handling heater.

• Never attach duct work to heater.

• Do not alter heater. Keep heater in its original state.

• Do not use heater if altered.

• Turn off propane supply and unplug heater when not in use.

• Use only original replacement parts. This heater must use design-specific

parts. Do not substitute or use generic parts. Improper replacement parts could

cause serious or fatal injuries.

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. If heater is damaged, promptly inform

dealer where you bought heater.

UNPACKING

THEORY OF

OPERATION

The Fuel System: The hose/regulator assembly attaches to the propane gas

supply. This provides fuel to the heater.

The Ignition System: The piezo ignitor lights the pilot fuel supply. The pilot

ignites the main burner.

The Automatic Control System: This system causes the heater to shut down

if the flame goes out.

PROPANE

SUPPLY

You must provide propane gas and propane tank(s).

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 temperatures. Your local propane gas dealer will

help you select the proper supply system.

Average Temperature (°F)

At Tank Location 60°40°32°20°10°0°

Number Of Tanks 111122

VENTILATION WARNING

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.

099684

4. Open propane supply valve on propane tank(s) slowly.

Note:

If not opened

slowly, excess-flow check valve on propane tank will stop gas flow. If this

happens, close propane supply valve and open again slowly.

INSTALLATION

3. Connect hose to the inlet connector. Tighten firmly using a wrench.

IMPORTANT:

Use extra hose or piping if needed. Install extra hose or piping

between hose/regulator assembly and propane tank. You must use the regula-

tor supplied with heater even if propane tank has one.

2. Connect POL fitting on hose/regulator assembly to propane tank(s). Turn POL

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.

To Start Heater

1. Follow all installation, ventilation, and safety information.

2. Locate heater on stable and level surface. Make sure strong drafts do not blow

on heater.

3. 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.

4. Push in and hold automatic control valve button (see Figure 4). Push piezo

ignitor button (see Figure 4). You may need to push piezo ignitor button 3-8

times until the pilot lights. When pilot lights, keep automatic control valve

button pushed in. Release after 30 seconds.

Note:

If pilot fails to light, hose may have air in it. If so, keep automatic control

valvebuttonpressedandwait20seconds.Releaseautomaticcontrolvalvebutton

and wait 20 seconds for unburned fuel to exit heater. Repeat step 4.

WARNING

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.

WARNING

Review and understand the warnings in the Safety Informa-

tion section, pages 2 and 3. They are needed to safely oper-

ate this heater. Follow all local codes when using this heater.

WARNING

Fully close main burner valve before lighting pilot. If not,

severe burns can occur. Do this by turning valve handle

towards the OFF position until it stops.

5. If pilot light goes out, repeat step 4.

6. When pilot remains lit, fully open main burner valve. Do this by turning valve

handle to the HIGH position. You can now position the handle to any setting

between HIGH and LOW.

CAUTION

Only use the main burner valve handle to adjust the burner

flame. Always turn handle pointer to the HIGH position

before turning it to a lower position. Never set handle

pointer between the LOW and OFF positions.

CAUTION

Running heater below specified input rating may cause

flashback. During flashback, the burner flame is mostly

yellow. The flame will burn inside the burner tube, causing a

roaring noise. If flashback occurs, turn heater off. After

burner tube cools, restart the heater.

Flame Patterns

Figure 5 shows a correct flame pattern. The burner flame is mostly blue with a

slight yellow coloring on the ends.

Figure 6 shows an incorrect flame pattern. The flame is mostly yellow. The

incorrect flame pattern results from running heater below the LOW position or
