INFORMATION |
|
|
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, |
|
|
||||
|
|
|
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. Get fresh air at 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. |
|
|
||||
|
|
|
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. |
|
|
|
|||
|
|
|
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. |
|
|
|
|||
|
|
|
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. This heater must have fresh air for proper operation. If not, poor fuel combustion |
|
|
||||
|
|
|
and improper venting of flue gases will result. Carbon monoxide poisoning from |
|
|
||||
|
|
|
backed-up flue gases could occur. The State of California lists carbon monoxide |
|
|
||||
|
|
|
as a reproductive toxin under Proposition 65. Read the instructions under Air for |
|
|
||||
|
|
|
Combustion and Ventilation, pages 17 through 20 for complete information. |
|
|
|
|||
|
|
|

Proper Size Vent |
|
To safely vent heater, the vent connector pipe must be the same diameter as the draft Continued hood outlet on the rear of the heater. Pipe that is too small can cause flue gas to spill
from the heater. Fasten vent connector to the draft hood outlet with a sheet metal screw.
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 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.

A qualified service person must connect heater to gas |
|
||
|
|
|
||
|
|
supply. Follow all local codes. |

|
|
WARNING ICON G 001 CAUTION |
|
|
|
|
Never connect heater directly to the propane supply. |
|
|
|
|
This heater requires an external regulator (not sup- |
|
|
|
|
plied). Install the external regulator between the heater |
|
|
|
|
and propane supply. |
|
|
|
|
|
|
|
|
The installer must supply an external regulator. The external regulator will reduce |
|||
|
incoming gas pressure. You must reduce incoming gas pressure to between 11 and |
|||
|
14 inches of water. If you do not reduce incoming gas pressure, heater regulator |
|||
|
damage could occur. Install external regulator with the vent pointing down as |
|||
|
shown in Figure 6. Pointing the vent down protects it from freezing rain or sleet. |

CAUTION
WARNING ICON |
G 001 |
Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe that is 1/2" in diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.
The gas supply line to your heater must be 1/2 inch in diameter or larger. If the supply line branches to serve two or more heaters, the line from the branch back to the external regulator must be doubled or tripled, etc., in size (depending upon the number of heaters). Example for 1/2 inch diameter supply line: If the supply line branches to serve two heaters, the line diameter from the branch back to the external regulator must be at least 1 inch. If three heaters are served, the line diameter from the branch back to the external regulator must be at least 1 1/2 inches.
Note: If gas supply line total length exceeds forty feet, use a larger diameter pipe. Use pipe that is the next size larger than the heater control valve fitting.

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. |

WARNING ICON G 001 |
CAUTION |
|
|
|
|
Use pipe joint sealant that is resistant to liquid petro- |
|
|
||||||
|
|
leum (LP) gas. |
|
|
|
|||||
|
|
|
|
|
||||||
|
Install sediment trap in supply line as shown in Figure 7. 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. |
|
|
|
||||||
|
IMPORTANT: Use two pipe wrenches when connecting gas piping to gas control |
|||||||||
|
valve of heater. This will prevent turning or damaging control valve. |
