OPERATING PRECAUTIONS

This is a propane, direct-fired, convection heater. It's intended 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. 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. 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.
4. Use only propane gas.
5. Use only VAPOR WITHDRAWAL propane supply. If there
is any question about vapor withdrawal, ask your propane
dealer.
6. Mount the propane cylinders vertically (shutoff valve up).
Secure them from falling or being knocked over and protect
them from damage.
7. Locate propane containers the designated distances
from heater. Additionally, Do not direct exhaust toward
containers.
For USA:
at least 7 ft. (2.13m) for the 25CVX, 80CVX units
at least 9 ft. (2.7m) for the 200CVX unit
For Canada:
at least 10 ft. (3m) for the 25CVX, 80CVX, 200CVX unit.

8. IMPORTANT Use only the hose and regulator assembly
provided with the heater. Match the color stripe on the hang
tag 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.
9. For indoor use only. Area must be well ventilated. Figure 1.
(Also see "Operating Precautions").
10. If at any time gas odor is detected, IMMEDIATELY
DISCONTINUE operation until the source of gas has
been located and corrected.
11. Install the heater such that it is not directly exposed to
water spray, rain and/or dripping water.
12. Maintain minimum clearance from normal combustible
material (like paper). Figure 2.
13. Due to the high surface and exhaust temperatures, adults
and children must observe clearances to avoid burns or
clothing ignition.
14. Operate only on a stable, level surface.
15. Do not use with duct work. Do not restrict inlet or exit.
16. Do not move, handle or service while hot or burning.
17. 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.
