Enerco Group, Inc. | Convection Construction Heater
OpERATINg pRECAUTIONS
This is a natural gas, direct-fired, convection heater. Its intended
use is primarily temporary heating of buildings under construction,
alteration or repair.
If natural gas leaks from a connection or fitting, it can mix with
the surrounding air, forming a potentially explosive mixture.
Obviously, natural gas leaks should be avoided, so set up the
natural gas supply with utmost care. Read enclosed odor Fade
Sheet for additional information about detecting natural gas
leaks. Leak check new connections or reconnections with a soap
and water solution and follow all connection instructions herein.
Also, ask your natural gas dealer for advice on the natural gas
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 producting 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.
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.

spray, rain and/or dripping water.
10. Maintain minimum clearance from normal combustible
material (like paper).
Figure 2
.
11. Due to the high surface and exhaust temperatures, adults and
children must observe clearances to avoid burns or clothing
ignition.
12. Operate only on a stable, level surface.
13. Do not use with duct work. Do not restrict inlet or exit.
14. Do not move, handle or service while hot or burning.
15. Use only in accordance with local codes or, in the absence of
local codes, with the Standard for the Storage and Handling
of Liquefied petroleum Gases ANSI/NfpA 58 and CSA b149.1,
natural Gas and Propane Installation Code.
