SAFETY

INFORMATION

WARNING ICON G 001

WARNINGS

IMPORTANT: Read this Owner’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, and carbon monoxide poisoning.

WARNING ICON G 001

DANGER

Carbon monoxide poisoning may lead to death!

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, persons with heart or lung disease or anemia, those under the

influence of alcohol, and those at high altitudes.

Natural Gas: Natural gas is odorless. An odor-making agent is added to natural

gas. The odor helps you detect a natural gas leak. However, the odor added to

natural gas can fade. Natural 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.

WARNING ICON G 001

WARNINGS

Continued

1. Use only natural gas. Do not convert heater to use different fuel type.

2. If you smell gas

• shut off gas supply

• do not try to light any appliance

• do not touch any electrical switch; do not use any phone in your building

• immediately call your gas supplier from a neighbor’s phone. Follow the

gas supplier’s instructions

• if you cannot reach your gas supplier, call the fire department

3. Never install the heater

• in sleeping quarters or a recreational vehicle

• where curtains, furniture, clothing, or other flammable objects are less than

36 inches from the front, top, or sides of the heater

• as a fireplace insert

• in high traffic areas

• in windy or drafty areas

4. Always run heater with control knob at LOW or HIGH locked positions

(VN12) or ON position (VN6A). Never set control knob between locked

positions. Poor combustion and higher levels of carbon monoxide may result.

5. Open window to admit fresh, outside air when using heater. Open window one

or two inches. When used without fresh, outside air, heater may give off

carbon monoxide gas.

6. Never run heater in small, closed room. Open door into next room to help

ventilate.

7. Keep all air openings in front and bottom of heater clear and free of debris.

This will insure enough air for proper combustion.

8. If heater shuts off, do not relight until you provide fresh, outside air. If heater

keeps shutting off, have it serviced.

9. Do not run heater

• where flammable liquids or vapors are used or stored

• under dusty conditions

10.Never place any objects on the heater.

11.Surface of heater becomes very hot when running heater. Keep children and

adults away from hot surface to avoid burns or clothing ignition. Heater will

remain hot for a time after shut-down. Allow surface to cool before touching.

12.Make sure grill guard is in place before running heater.

13.Do not alter heater or its controls. Any change may create a safety hazard.

14.Do not use heater if any part of heater has been under water.

15.Turn off heater and let cool before servicing. Only a qualified service person

should service and repair heater.

16.Do not operate heater above elevations of 4,500 feet.

LOCATING HEATER

This heater is designed to be mounted on a wall.

WARNING ICON G001

WARNING

Maintain the minimum clearances shown in Figure 2 (page 6). If you

can, provide greater clearances from floor, ceiling, and joining wall.

WARNING ICON G001

WARNING

Never install the heater

• in sleeping quarters, a mobile home, or a recreational vehicle

• where curtains, furniture, clothing, or other flammable objects

are less than 36 inches from the front, top, or sides of the heater

• as a fireplace insert

• in high traffic areas

• in windy or drafty areas

WARNING ICON G 001

CAUTION

If you install the heater in a home garage

• heater pilot and burner must be at least 18 inches above floor

• locate heater where moving vehicle will not hit it

WARNING ICON G 001

CAUTION

Operating heater where impurities in the air (such as tobacco

smoke) exist, may discolor walls.

For convenience and efficiency, install heater

• where there is easy access for operation, inspection, and service

• in coldest part of room Continued

2. Mark two mounting screw locations on wall (see Figure 3).

using 9/64" drill bit.

5. Replace heater on wall.

6. Insert bottom anchor screw through back panel into bottom anchor or drilled

hole (see Figure 9).

7. Tighten screw until heater is firmly secured to wall. Do not over tighten.

Note:

Do not replace front panel at this time. Replace front panel after making

gas connections and checking for leaks (see pages 9-11).

CONNECTING

TO GAS

SUPPLY

Continued

WARNING ICON G001

WARNING

Never connect heater to private (non-utility) gas wells. This gas is

commonly known as well-head gas.

Installation must include a manual shutoff valve, ground joint union, and plugged

1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must

be upstream from heater (see Figure 10, page 10).

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant

from going into pipe. Excess sealant in pipe could result in clogged heater valves.

Install sediment trap in supply line as shown in Figure 10. 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.

WARNING ICON G001

CAUTION

Use only new, black iron or steel pipe. Copper tubing may be used

in certain areas. Check your local codes. Use pipe 3/8" diameter or

greater to allow proper gas volume to heater. If pipe is too small,

undue loss of pressure will occur.

WARNING ICON G 001

CAUTION

Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

IMPORTANT:

Check gas line pressure before connecting heater to gas line. Gas

line pressure must be no greater than 14 inches of water. If gas line pressure is

higher, heater regulator damage could occur.

NOTICE

A qualified service person must connect heater to gas supply.

Follow all local codes.

IMPORTANT:

Holdpressure regulator with wrenchwhenconnecting it to gaspiping

and/or fittings.

1. Disconnect heater and its individual manual shutoff valve from gas supply

piping system. Pressures in excess of 1/2 PSIG will damage heater regulator.

2. Cap off open end of gas pipe where manual shutoff valve was connected.

3. Pressurize supply piping system by either using compressed air or

opening main gas valve located on or near gas meter.

CHECKING

GAS

CONNECTIONS

WARNING ICON G 001

WARNING

Test all gas piping and connections for leaks after installing or

servicing. Correct all leaks at once.

WARNING ICON G 001

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.

Correct all leaks at once.
