GENERAL SAFETY INSTRUCTIONS:

SAFETY : Accidents are always tragic especially because so many of them could have been prevented with a little care and judgment. There are some basic good practices we hope you will follow for safe use of yourgas-firedroom heater.

IMPORTANT : Read this user's manual carefully and completely before trying to assemble, operate, or service this heater. Improper use of this heater can cause serious injury or death from burns, fire, explosion, electrical shock, and carbon monoxide poisoning.

Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once! Have heater serviced. Some people are more affected by carbon monoxide than others. These include pregnant women, people with heart or lung disease or anemia, those under the influence of alcohol, and those at high altitudes.

Begin by insuring proper installation and servicing. Follow the installation instructions provided with this product. Have your heater installed by a qualified technician. Have the installer show you where the gas supply shut off valve is located so that you know where to shut off the gas to the heater. If you smell gas, your installer has not done a proper job of checking leaks. If the connections are not perfectly seated or tightened, you may have a leak and therefore a faint gas smell. Finding a leak is not a DO-IT-YOURSELF procedure. Some leaks can only be found with the main burner gas on and this must be done by a qualified technician.

PRECAUTIONS:

Never use natural gas in a unit designed for liquefied petroleum gases.

Never use liquefied petroleum gases in a unit designed for natural gas.

Check all joints and connections. To avoid the danger of fire, accident or explosion, never check a potential gas leak with an open flame.

This heater shall not be installed in a bedroom or bathroom.

Never install the heater in any of the following locations: Recreational vehicle

Where curtains, furniture, clothing, or other flammable objects are less than 36 inches from the front, top, or sides of the heater

Fireplace

High traffic area Drafty areas

This heater needs fresh, outside air for ventilation to run properly. This heater has an oxygen depletion sensor(ODS)pilot light safety system. The ODS shuts down the heater if not enough fresh air/oxygen content(18%)is available.

Never run heater in confined space. Open a door to an adjoining room to help

ventilate(For air openings, see National Fuel Code).

Page 2

If heater shuts off, do not relight until you provide fresh, outside air. If heater keeps shutting off, have it serviced.

Do not run heater where :

Flammable liquids or vapors are used or stored. Dusty condition exists.

Never place any objects on the heater.

PRODUCT FEATURES:

Safety Device

This heater has a pilot with an Oxygen Depletion Sensor Shutoff System (ODS).

The ODS pilot is a required feature for vent-freeroom heaters. The ODS pilot shuts off the heater if the normal air oxygen content is reduced to 18%.

Piezo Ignition System

This heater has a piezo ignitor. This system requires no matches, batteries, or other sources to light heater.

Thermostatic Heat Control

Thermostat has a sensing bulb, and a control valve. This results in the greatest heater comfort. This can also result in lower gas bills.

FRESH AIR FOR COMBUSTION AND VENTILATION:

WARNING : This heater must have fresh air for proper operation. If not, poor fuel combustion could result. Read the following instructions to insure proper fresh air for this and otherfuel-burningappliances in your home.

ADEQUATE COMBUSTION/VENTILATION AIR

All spaces in homes fall into one of the three following ventilation classifications: Unusually Tight Construction : The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air. Unusually Tight Construction is defined as construction where:

-Wallsand ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating or one perm or less with openings gasketed or sealedand

-Weatherstripping has been added on openable windows and doors-Caulkingor sealants are applied to areas such as joints around window and door frames, between sole plates and floors, betweenwall-ceilingjoints,

between wall panels, at penetrations for plumbing, electrical and gas lines, and at other openings.

Unconfined Space

An unconfined space whose volume is not less than 50 cubic feet per 1,000 BTU/HR of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed, Though the openings not furnished with doors are considered a part of the unconfined space.

Confined Space

A confined space whose volume is less than 50 cubic feet for each 1,000 BTU/HR of the aggregate input rating of all appliances in that space.

WARNING : You must provide additional ventilation air in a confined space.

For proper operation of the unit, provide fresh air opening(s) to the room. Follow the National Fuel Code NFPA 54 / ANSI Z223.1, for required size of combustion and ventilation openings.

3.Installation and repair should be done by a qualified service person. The room heater should be inspected before use and at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting and other materials. It is imperative that the control compartments, burners and circulating air passageways of the heater be kept clean.

CONNECTING TO GAS SUPPLY :

WARNING : Never connect an unregulated gas line to the heater.

An installer supplied, design certified gas pressure regulator must be installed to bring the gas supply pressure down to 14 inches of water column.

IMPORTANT : Check gas line pressure before connecting heater to gas line.

Gas line pressure must not be higher than 14 inches of water. If gas line pressure is higher, heater gas pressure regulator damage could occur.

CAUTION : Use only new, black iron or steel pipe.Internally-tinnedcopper tubing may be used in certain areas. Check your local codes. Use pipe of large enough diameter to allow proper gas volume to heater. If pipe is too small, undue pressure loss will occur.

Typical Gas Supply Pipe Diameters

10,000 BTU/HR Model 3/8" or greater

20,000 BTU/HR Model 3/8" or greater

30,000 BTU/HR Model 3/8" or greater

CAUTION:

Use pipe joint sealant that is resistant to liquefied petroleum gases.

Install sediment trap in supply line as shown in Figure 8 Gas Connection. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.
