SAFETY
INFORMATION
FOR YOUR SAFETY
Do not use this heater in a space where gasoline or other
liquids having flammable vapors are stored or used.
!
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, electrical shock, or carbon monoxide poisoning.
Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning
resemble the flu, with headaches, dizziness, and/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.
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.

INFORMATION
Continued
• Not for domestic use (inside living areas). Use heater for space heating only.
• Primarily intended for temporary heating of buildings under construction,
alteration, or repair.
• Install and use heater with care. Follow all local ordinances and codes.
• Use only in a well-vented area away from combustible materials.
• Provide proper ventilation. If not, excessive levels of carbon monoxide (CO)
and carbon dioxide (CO
for ventilation. One opening should be near the floor, the other opening near
the ceiling. Each ventilation opening must be at least 130 cm2.
• Never use heater where gasoline, paint thinner, or other highly flammable
vapors are present. Use only in places free of flammable vapors or high dust
content.
• Do not use heater below ground level. Propane gas is heavier than air. If a
leak occurs, propane gas will sink to the lowest possible level.
• Keep heater away from strong drafts, water spray, rain, or dripping water.
• Check heater for damage before each use. Do not use a damaged heater.
• Use only propane gas, I3P.
• Keep propane tank(s) below 38° C.
• Unhook heater from propane and electrical supply before moving or when not
in use.
• Use only the electrical voltage and frequency specified on model plate.
• Use only the hose and regulator provided with the heater.
• Inspect hose before each use. If cut, worn, or damaged, replace before using
heater. Use the replacement hose assembly specified in this manual.
• Keep heater at least two meters from propane tank(s). Do not point heater at
propane tank(s).
• Minimum heater clearances from combustibles:
Outlet: 3 meters Sides: 1 meter Top: 2 meters Rear: 1 meter
• Locate heater on stable and level surface if heater is hot or running.
• Keep children and animals away from heater.
• Never block air inlet (rear) or air outlet (front) of heater.
• Never move, handle, or service a hot, operating, or plugged-in heater.
• Do not alter heater. Keep heater in its original state.
• Do not use heater if altered.
• Never attach duct work to front or rear of heater.
• Use only original replacement parts. This heater must use design-specific
parts. Do not substitute or use generic parts. Improper replacement parts could
cause serious or fatal injuries.

THEORY OF
OPERATION
Figure 1 - Model BLP35ES
The Fuel System: The hose/regulator assembly attaches to the propane gas
supply. This provides fuel to the heater.
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 ignitor lights the burner.
The Burner Control System: This system causes the heater to shut down if
the flame goes out.

SUPPLY
User must provide propane gas and propane tank(s).
Use this heater only with a propane vapor withdrawal supply system. The amount
of propane gas ready for use from propane tanks varies. Two factors decide this
amount:
1. The amount of propane gas in tank(s)
2. The temperature of tank(s)
This heater is designed to operate with a minimum 9-kg propane tank. You may
need two or more tanks or one larger tank in colder weather. Use a 45-kg tank for
longer operation or in very cold weather. Less gas is vaporized at lower temperatures. Your local propane gas dealer will help you select the proper supply system.

INSTALLATION
Review and understand the warnings in the Safety Information Section, pages 2 and 3. They are needed to safely operate this heater. Follow all local codes when using this heater.
Test all gas piping and connections for leaks after installation
or servicing. 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.
1. Provide propane supply system (see Propane Supply, above).
2. Connect fuel gas connector on hose/regulator assembly to propane tank(s).
Tighten firmly using wrench.
leaving the regulator is in a horizontal position (see Figure 3). This places the

2. Wait a few seconds. Heater will burn gas left in supply hose.
3. Unplug heater.
To Restart Heater
1. Wait five minutes after stopping heater.
2. Repeat steps under To Start Heater, page 6.
To Change Propane Tank(s)
Change propane tank(s) in a flame-free area. Use only propane gas, I3P.
1. Tightly close the propane supply valve(s) on the propane tank(s).
2. Disconnect the hose/regulator assembly from the propane tank(s).
3. Connect the hose/regulator assembly to the new propane tank(s). Tighten
firmly.
4. Check all connections for leaks.
