the heater may not be working properly. Get

fresh air at once! Check for proper ventilation

and have heater serviced.

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 can fade. Propane gas may be present

even though no odor exists.

warnings. Keep this manual for reference. It

is your guide to safe and proper operation of

this heater.

1. Install and use heater with care. Follow

all local ordinances and codes. In the ab-

sence of local ordinances and codes, refer

to the Standard for Storage and Handling

of Liqueed Petroleum Gas, ANSI/NFPA

58 and the Natural and Propane Gas

Installation Code, CAN/CGA B149.1. This

instructs on the safe storage and handling

of propane gases.

THEORY OF OPERATION

The Fuel System: The hose/regulator as-

sembly attaches to the propane gas supply.

This provides fuel to the heater.

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.

PROPANE SUPPLY

Propane gas and propane tank(s) are to be

furnished by the user.

Use this heater only with a propane vapor

withdrawal supply system. See Chapter 5

of the Standard for Storage and Handling of

Liqueed Petroleum Gas, ANSI/NFPA 58 and/

or CAN/CGA B149.2. Your local library or re

department will have this booklet.

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)

This heater is designed to operate with a

minimum 20 lb (9 kg) propane tank. You may

need two or more tanks or one larger tank in

colder weather. It is recommended you use a

100 lb (45 kg) tank for longer operation. See

chart below. Less gas is vaporized at lower

temperatures. Your local propane gas dealer

will help you select the proper supply system.

The minimum surrounding air temperature

rating for each heater is 0° F (-18° C).
