4.2 - General Safety Information
Safety Precautions:
It is necessary to follow these safety precautions, each time, prior to using the product.
The Safety Precautions are not limited to, but must include the following items;
1.
Do not use the heater / blower for anything other than its intended use.
2.
This heater is designed to function with a two-stage regulator system. A first stage regulator is required at the
bottle, dropping the gas pressure down to 10-35 psi (pounds per square inch). The regulator built into the unit then
drops the hose pressure further to 10” WC (water column) for use within the heater.
3.
Make sure all L.P. fittings are tight. Only a pipe joint compound that is resistant to liquified petroleum gases should be
used.
4.
The propane bottle must be a vapor draw style, DOT (for U.S.) or CTC (for Canada) approved, 20 or 40 lbs gas cylin-
der. Do not use a forklift or liquid withdrawal cylinder. Use only LPG (propane) fuel.
5.
Propane gas is very flammable. Propane is scented such that its strong odor is readily detectable. If a gas odor is
detected at any time, do not operate or continue to operate the unit until the source of the gas odor has been located.
In the event of a leak, propane is heavier than air and will accumulate in low areas.
Never strike a match, create a
spark or flame when you smell gas
. Move the heater outside and ventilate the area. Find and correct the source
of the leak before attempting to light the heater. If the leak cannot be corrected, do not tamper with the heater. Turn
the heater off and consult the manufacturer or a qualified technician.
6.
Do not lean over the heater during ignition or operation;
do not wear loose clothing that can become entan-
gled in operating machinery. Do not operate the heater / blower without inlet and outlet screen guards in place.
Do not place fingers or any other object through inlet or outlet screens.
7.
Do not move, handle or service the unit while hot or burning. Permanent skin tissue damage can occur if contact is
made with the unit. Let the heater cool down after it has been shut off.
8.
Never direct this construction heater toward any LP gas cylinder within 20ft. The heater must be a minimum
of six feet from any LP Gas cylinder. keep away from fabric or combustibles.
refer to clearance table below for
distances
. Survey the work area for an potential hazards and correct them before operating the heater.
9.
Unit should be used in a well ventilated area. When heater is in use, a positive air displacement of at least 4-CFM
per 1,000 BTUH of the heater’s rated output should be provided. The #1590 is rated at 45,000 BTU’s, thus the flow
must maintain a volumetric rate of at least 180 CFM (the #1590 is rated at 432 CFM in a free air configuration).
10.
Always operate the heater / blower from a properly grounded receptacle.
11.
Never handle energized power cords with wet hands. Never let extension cords or plug connections lay in water.
Locate the heater / blower so that it cannot fall into water inadvertently.
12.
Never use cords with frayed, cut, or brittle insulation. Check the cord for sound connections to the ground fault
interrupter receptacle.
13.
Never use the heater / blower in an explosive environment.
14.
Ensure that toxic fumes are not blown into a confined space.
