OPERATING PRECAUTIONS
is primarily temporary heating of buildings under construction,
alteration or repair.
Propane is heavier than air. If propane leaks from a connection or
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.
heater in accordance with ANSI Z83.7a/CGA 2.14a-2007. Check
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. The symptoms of inadequate ventilation are:
•
headache
•
dizziness
•
burning eyes and nose
•
nausea
•
dry mouth or sore throat
So, be sure to follow advice about ventilation in these operating
instructions.
Forced Air means that a blower or fan pushes the air through the
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.
