OPERATING PRECAUTIONS

This is a natural gas, direct-fired, forced air heater. It's intended
use is primarily temporary heating of buildings under
construction, alteration or repair.

If natural gas leaks from a connection or fitting, it mixes with
the surrounding air, forming a potentially explosive mixture.
Obviously, gas leaks should be avoided, so set up the gas
supply with utmost care. Read enclosed Odor Fade Sheet
for additional information about detecting gas leaks. Leak
check new connections or reconnections with a soap and
water solution and follow all connections instructions herein.

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.

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. Use only natural gas.

4. Provide at least 5" W.C. but not over 1/2 psig to the heater
inlet (regulator inlet).

5. Use an appropriate hose or flexible connector not over 10 ft.
(3.05m) in length.

6.Operate the heater only with the 4" W.C.regulator

provided by the factory.

7. For indoor use only. Area must be well ventilated. Figure 1.
(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.
for additional information about detecting gas leaks.

10. Install the heater such that is is not directly exposed to water
spray, rain and/or dripping water.

11. Maintain minimum clearance from normal combustible

material (like paper). Figure 2.

12. Due to the high surface and exhaust temperatures, adults
and children must observe clearances to avoid burns or
clothing ignition.

13. Operate only on a stable, level surface.

14. Do not use with ductwork. Do not restrict inlet or exit.

15. Use only the electrical power specified. The electrical
connection and grounding must comply with National
Electrical Code - ANSI/NFPA 70.

16. Use only a properly grounded 3-prong receptacle and
extension cord.

17. Do not move, handle or service while hot or burning.

18. Use only in accordance with local codes.

Read enclosed Odor Fade Sheet

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.
