WARNING
NOT FOR HOME OR RECREATIONAL VEHICLE USE.
This product is designed and approved for use as an indoor construction heater in accordance
with standard ANSI Z83.7 - CSA
2.14 - (2000).
We cannot foresee every use which may be made of our heaters. Check with your local fire
safety authority if you have questions about heater use.
Other standards govern the use of fuel gases and heat producing products for specific uses.
Your local authorities can advise you about these.
This indoor construction heater should not be used in areas directly exposed to water spray,
rain, and/or dripping water.
CARBON MONOXIDE POISONING:
This construction heater is a combustion appliance. All combustion appliances
produce carbon monoxide (CO) during the combustion process. This product is designed to
produce extremely minute, non-hazardous amounts of CO if used and maintained in
accordance with all warnings and instructions. Do not block air flow into or out of the
heater.
Early signs of carbon monoxide poisoning may resemble the flu with headaches,
dizziness and/or nausea. If these symptoms are present during operation of this product get
fresh air immediately!
ENGLISH
3
MAKE SURE ADEQUATE VENTILATION IS PROVIDED. Provide a fresh
outside air opening at least three (3) square feet (0.3 m
2
) or its equivalent, i.e., 1' x 3' (0.3 m
x 0.9 m) for each heating unit. DO NOT USE THIS HEATER IN LIVING QUARTERS
OR WHILE SLEEPING! California lists carbon monoxide as a reproductive toxin under
Proposition 65.
PROPANE GAS:
This product is fueled by propane gas. Propane gas is invisible, odorless, and
flammable. An odorant is normally added to help detect leaks and can be described as a
“rotten egg” smell. The odorant can fade over time so leaking gas is not always detectable
by smell alone.
Propane gas is heavier than air and leaking propane will sink to the lowest level
possible. It can be ignited by ignition sources including matches, lighters, sparks or open
flames of any kind many feet away from the original leak. Use only propane gas set up for
vapor withdrawal.
Propane gas should be stored and used in compliance with local ordinances and
codes or with ANSI/NFPA58. Turn off propane when not in use.
FIRE/EXPLOSION:
During operation, this product can be a source of ignition. Keep heater area clear
and free from combustible materials, gasoline, paint thinner, cleaning solvents and other
flammable vapors and liquids. Do not use heater in areas with high dust content.
MINIMUM HEATER CLEARANCES FROM COMBUSTIBLE MATERIALS: TWO
(2) FEET (0.6 M) FROM SIDES AND REAR, FOUR (4) FEET (1.2 M) FROM TOP,
AND SIX (6) FEET (1.8) FROM THE OUTLET. Keep heater at least six (6) feet (1.8 m)
away from propane tanks and keep propane hoses away from outlet opening of the heater.
ADDITIONAL SAFETY INFORMATION:
• Never alter or modify heater, propane hose/regulator assembly or propane cylinders.
Do not attach duct work of any kind to this heater.
• Always inspect heater, propane hoses and propane cylinders before use. Do not use
if leaking propane or if damaged. Replace hoses that have excessive wear, abrasion
or cuts. Use only Coleman repair parts and Coleman propane hoses and regulator
assemblies.
• KEEP OUT OF REACH OF CHILDREN.
• Heater will remain hot up to thirty (30) minutes after being turned off.
• Operate heater only on level, stable surface.
• Use only the electrical voltage and frequency specified on product decal.
• Electrical grounding instructions — this heater is equipped with a three-prong
(grounding) plug for your protection against shock hazard and should be plugged
directly into a properly grounded three-prong receptacle.
• Use only a three-prong, grounded extension cord.
• Make sure heater is plugged into outlet before igniting heater.
• Keep the appliance area clear and free from combustible materials, gasoline and
other flammable vapors and liquids.
• Do not block or obstruct the flow of combustion and ventilation air.
• Blower (forced air) and radiant type heaters must not be directed toward any
propane-gas container within 20 feet (6 m).

1. Remove all packing items applied to heater for shipment. Keep plastic cover caps
(attached to inlet connection and hose/regulator assembly) for storage.
2. Remove all items from carton.
3. Check all items for shipping damage. If heater is damaged, promptly inform dealer
where you bought heater.
The Fuel System: The hose/regulator assembly attaches to the propane gas supply. The
propane gas moves through the thermoelectric valve and out the nozzle.
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 spark ignitor (Model 5070A) or Electronic Module
(Model 5075A) sends voltage to the electrode. The spark at the electrode ignites the fuel
air mixture.
The Safety Control System: This system causes the heater to shut down if the heater
overheats for any reason including loss of electric power. (The fan will continue to operate
if electric power is not lost.)
