Operating Instructions and Owner’s Manual

Convection Construction Heater

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.

Figure 2

MINIMUM CLEARANCE: From normal combustible material

25CVX, 80CVX, 200CVX
Clearance

Convection

From sides ..................................................4 ft

From top ....................................................6 ft

Locate 10'  from canvas or plastic tarpaulins or similar coverings 
and secure them to prevent flapping or movement due to wind 
action.

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.
