SAFETY

INFORMATION WARNINGS

IMPORTANT: Read this owner’s manual carefully and completely be-

foretrying toassemble, operate, orservice thisheater. Improperuse of

thisheatercancauseseriousinjuryordeathfromburns,fire,explosion,

electrical shock, and carbon monoxide poisoning.

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 operating or venting properly. Getfresh airat once!Have heater

or heater venting system 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.

PropaneGas: Propanegasis odorless.Anodor-making agentis addedtopropane

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.

Makecertain you read and understandallWarnings.Keepthis manual for reference.

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

1. A qualified service person must install heater and venting system.

2. Use only propane gas. Do not convert heater to use different fuel type.

3. Do not place propane supply tank(s) inside any structure. Locate propane supply

tank(s) outdoors.

4. 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.

5. Thisheatermusthave fresh air for proper operation. If not, poor fuel combustion

andimproperventingoffluegases will result. Carbon monoxide poisoning from

backed-up flue gases could occur. The State of California lists carbon monoxide

asareproductivetoxinunderProposition65.ReadtheinstructionsunderFreshAir

for Combustion and Ventilation, pages 16 through 19 for complete information.

6. Never install the heater

• in a mobile home or a recreational vehicle.

• where curtains, furniture, clothing, or other flammable objects are less than 48

inches from the front, 53 inches from top, or 12 inches from right side and 6

VENTING HEATER

INSTALLING

HEATER

Continued

WARNING

A qualified service person must install the venting system

for this heater. If venting system is not properly installed

and maintained, the vent safety shut-off system will pre-

vent the heater from running. Follow all local codes.

WARNING

This heater has a vent safety shut-off system. This

system shuts off the heater gas supply if you do not vent

heater properly or the venting system is blocked. Do not

operate heater if not properly vented. Do not tamper with

the vent safety shut-off system. Carbon monoxide poison-

ing and death may result.

WARNING

When venting this heater, follow the safety information

listed below.

•Never vent heater to another room or inside a build-

ing. Only vent heater to the outdoors.

•Do not vent heater exhaust to a chimney or flue

serving another solid-fuel-burning or gas appliance.

•We recommend you use flues classified as prefabri-

cated or masonry all-fuel chimney or type-B vent. See

Vent Types,

page 10.

•If using old vent, check vent for soot, creosote, and

loose particles. If vent is damaged, repair or replace

it before using heater.

•Extend the vertical section of vent pipe at least three

feet above roof penetration.

•Extend the vertical section of vent pipe at least two

feet above the highest point of any roof within ten

feet.

•The horizontal run of vent pipe should rise at least

1/4 inch for each foot of run.

•Support the vent pipe at least every five feet along its

length. Do not use combustible materials to support

vent pipe.

•Never extend vent pipe horizontally through outside

wall and terminate. You must connect a vertical run

of vent pipe to the horizontal run. The vertical run

must be at least 25% longer than the horizontal run.

•Install vent or chimney cap that is approved for use

with vented gas room heaters.

•Do not use vent pipe smaller in diameter than that of

the heater draft hood outlet.

•Do not use dampers in the vent pipes.

•Vertical height of vent must be greater than five feet

above vent connection at draft hood.

Proper Size Vent

To safely vent heater, the vent connector pipe must be the same diameter as the draft

hood outlet on the rear of the heater. Pipe that is too small can cause flue gas to spill

fromtheheater.Fastenventconnectortothedrafthoodoutletwithasheetmetalscrew.

Vent Types

Prefabricated or Masonry All-Fuel Chimney - This is a masonry chimney or a

residential-type prefabricated chimney. Only use prefabricated chimneys listed by

Underwriters Laboratories (UL), Inc.

Type-B Vent - These vents are made of noncombustible, corrosion resistant

material. They are certified by a nationally recognized testing agency. Type-B

vents are double-

walled pipe. Clearances to combustible construction must be in

accordance with the listing of the particular type-B vent. Type-B vents are currently

listed as B-1, B-1

/2, and B-2.

The illustrations below show both vent types. The illustration shows typical

construction of each type of venting system. Minimum clearances and lengths are

added to the illustrations.
