Operating Instructions and Owner’s Manual

Mr. Heater, Inc.| Forced Air Propane Construction Heater

NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING!

OPERATING PRECAUTIONS

This is a propane, direct-fired, forced air 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. Read enclosed Odor Fade
and Propane Sheet for additional information about detecting
propane leaks. Leak check new connections or reconnecting
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 Z83.7/CGA 2.14. 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.

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.

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 propane gas.
4. Use only VAPOR WITHDRAWAL propane supply. If there

is any question about vapor withdrawal, ask your propane

dealer.

5. Mount the propane cylinders vertically (shutoff valve up).

Secure them from falling or being knocked over and protect

them from damage.

6. Locate propane containers at least (USA) 7 ft. (2.13m),

(Canada) 10 ft. (3m) from the heater and

do not

direct

exhaust toward containers.

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.

8. For either indoor or outdoor use. Adequate ventilation must

be provided.

Figure 1

. (also see "Operating Precautions").

9. 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 and

Propane Sheet for additional information about detecting

propane leaks.

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.  Use only the electrical power specified. The electrical

connection and grounding must comply with National

Electrical Code - ANSI/NFPA 70 (USA) and CSA C22.1

Canadian Electrical Code, Part 1 (Canada).

15. Use only a properly grounded 3-prong receptacle or

extension cord.

16. Do not move, handle or service while hot or burning.
17. Do not adjust the heater combustion tube elevation while

heater is running or hot. Adjustments to elevation should

only be made after the heater has cooled to touch.

18. 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.
