Convection Construction Heater
E-3
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.
SAFETY PRECAUTIONS
1. Check the heater thoroughly for damage. DO NOT operate a
damaged heater.
2.
DO NOT
modify the heater or operate a heater which has
been modified from its original condition.
3.
DO NOT
light or operate heater unless the shells are fully
extended and locked into position. See enclosed assembly
sheet for instructions.
4. Use only Natural gas.
5. Protect all heater natural gas connections from traffic or
damage.
6.
IMPORTANT:
Use only the regulator assembly provided with
the heater. Inspect flexoble natural gas connections before
each use of the heater. I there is excessive abrasion or wear,
or connection is damaged in any way, replace with connection
that meets all local, state, etc. codes and requirements.
7. For indoor use only. Area must be well ventilated.

(also see "Operating Precautions").
8. If at any time gas odor is detected, IMMEDIATELY
DISCONTINUE operation until the source of gas has been
located and corrected. Read enclosed Odor fade Sheet for
additional information about detecting gas leaks.
9. Install the heater such that it is not directly exposed to water
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.
