Operating Instructions and Owner’s Manual
Mr. Heater |Force-Air Propane Construction Heater
OPERATING PRECAUTIONS
This is a propane, direct-fired, forced air heater. It's intended
use is primarily temporary heating of buildings under
construction, alteration or repair.
use is primarily temporary heating of buildings under
construction, alteration or repair.
Propane is heavier than air. If propane leaks from a
connection or fitting, it sinks to the floor, collecting there
with the surrounding air, forming a potentially explosive
mixture. Obviously, propane leaks should be avoided, so set
up the propane supply with utmost care. Read enclosed
Odor Fade and Propane Sheet for additional information
about detecting propane leaks. Leak check new connections
or reconnections with a soap and water solution and follow
all connection instructions herein. Also, ask your propane
dealer for advice on the propane application and supply
installation and ask him to check it if there are any questions.

This heater was designed and certified for use as a
construction heater in accordance with ANSI Standard
Z83.7/CGA 2.14-2000. Check with your local fire safety
authority if you have any questions about your applications.
Other standards govern the use of fuel gases and heat
producing products in specific applications. Your local
authority can advise you about these.

Direct-Fired means that all of the combustion products enter
the heated space. Even though this heater operates very
close to 100 percent combustion efficiency, it still produces
small amounts of carbon monoxide. Carbon monoxide (called
CO) is toxic. We can tolerate small amounts but not a lot. CO
can build up in a heated space and failure to provide
adequate ventilation could result in death.

can build up in a heated space and failure to provide

The symptoms of inadequate ventilation are:
• headache
• dizziness
• burning eyes and nose
• nausea
• dry mouth or sore throat

operating instructions.
Forced Air means that a blower or fan pushes the air
through the heater. Proper combustion depends upon this
air flow; therefore, the heater must not be revised, modified
or operated with parts removed or missing. Likewise, safety
systems must not be circumvented or modified in order to
operate the heater.

When the heater is to be operated in the presence of
other people the user is responsible for properly
acquainting those present with the safety precautions
and instructions, and of the hazards involved.

IMPORTANT Use only the hose and regulator assembly
provided with the heater. Match the color stripe on the
hangtag attached to the hose assembly with the color on the
label located near the propane inlet fitting on the heater.
Inspect hose assembly before each use of the heater. If there
is excessive abrasion or wear, or hose is cut, replace with
hose assembly listed on parts list before using heater.
