OPERATING INFORMATION
SAFETY PRECAUTIONS
This is a propane, direct-fired heater.
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 supply installation
and ask him to check it if there are any questions.
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.
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.
!
WARNING: FIRE, BURN, INHALATION, AND EX-
PLOSION HAZARD. KEEP SOLID COMBUSTIBLES, SUCH
AS BUILDING MATERIALS, PAPER OR CARDBOARD, A
SAFE DISTANCE AWAY FROM THE HEATER AS RECOMMENDED BY THE INSTRUCTIONS. NEVER USE THE HEATER
IN SPACES WHICH DO OR MAY CONTAIN VOLATILE OR
AIRBORNE COMBUSTIBLES, OR PRODUCTS SUCH AS
GASOLINE, SOLVENTS, PAINT THINNER, DUST PARTICLES
OR UNKNOWN CHEMICALS.
FOR YOUR SAFETY
If you smell gas:
1. Shut off gas to the appliance.
2. Extinguish any open flame.
3. If odor continues, immediately call
your gas supplier.
Tools Required
8 mm Socket and Driver or Screwdriver
#2 & #3 Philips Head Screwdriver
Open End Wrenches: 10mm, 11mm, 12mm, 3/4"
Teflon Tape - Pipe Thread Sealer
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. Never use the heater if the ballast weight is not assembled onto the base. The base must be weighted to avoid
tipping.
6. Use only the hose and regulator assembly provided
with 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.
7. This heater is for outdoor use only, even so make sure
that there is ample fresh air ventilation. Do not use in
buildings, garages or other enclosed spaces.
8. If at any time gas odor is detected, IMMEDIATELY
DISCONTINUE operation until the source of gas has
been located and corrected.
9. Install the heater such that it is not directly exposed to
water spray, rain and/or dripping water or wind.
10. Maintain minimum clearance to people or normal
combustible material (like paper) of 3 feet from top, 2
feet from the reflector.
11. Operate only on a stable, level surface.
12. Do not move, handle or service while hot or burning.
13. Use only in accordance with local codes or, in the
absence of local codes, with the National Fuel Gas Code
ANSI Z223.1.
14. Do not hang or attach clothing or any other combustible
materials from, on or near the heater.
15. Check control compartment burners and circulation air
passageways for free air passage, make sure that there
are no obstructions. These areas are a common location
for spider webs, which can present a dangerous condition, damage the heater and render it unsafe for use. The
heater must be checked if any of the following conditions
exist:
a) Gas smell along with predominate yellow tipping of
the burner flames.
b) Heater does not reach temperature.
c) Uneven burner glow.
d) Burner makes popping noises during normal use,
other than during shutdown.
16. Care must be taken for the supervision of children in the
vicinity of an operating heater.
17. Due to high surface termperatures adults and children
must observe clearances to avoid burns or clothing
ignition.

GAS REQUIREMENTS
The heater comes with a regulator/hose assembly for
hook-up to a standard 20 pound LP gas tank (18- 1.4" high,
12- 1/4" diameter). The LP tank is not included. A
dented or rusty LP tank may be hazardous and
should be checked by your LP supplier. Never use an
LP tank with a damaged valve. The LP tank must be
arranged to provide for vapor withdrawal from the operating
cylinder. Never connect an unregulated LP tank to the
heater. The heater is shipped from the factory for LP use,
never substitute gases
LP Gas Hook-up:
The heater is designed to house a 20 pound gas cylinder
in the base assembly. Lift the cylinder cover, and place the
LP cylinder into the housing. The regulator can then be
screwed into the LP cylinder, the regulator and the tank
have right-handed threads (clockwise to tighten. No teflon
tape is required). When tightening be careful not to put too
much force on the LP cylinder valve.
ASSEMBLY INSTRUCTIONS
NOTE: Assembly of this heater requires basic
mechanical skills. Proper assembly is the
responsibility of the installer Installation and
repair should be done by a qualified service
person.
STEP 1:
Attach the three base support legs on the base using three (3)
M6-1.25 x 20mm hex head bolts, three (3) M6 lock washers,
six (6) flat washers, and three (3) M6-1.25 nuts.
Figure 1: Step 1, 2 & 3
STEP 4:
Slide the cylinder cover over the base module assembled
in the previous steps. See figure 2.
STEP 2:
Place the ballast weight plate under the base. Tighten the
weight and base together using four (4) M6-1.25 x 25mm hex
head bolts, four (4) M6 lock washers, eight (8) M6 flat washers
and four (4) M6-1.25 nuts.
STEP 3:
Place the post support on the base support legs (see figure 1).
Tighten the post support and the base support legs together
using six (6) M6-1.25 x 20mm hex head bolts, six (6) M6 lock
washers, twelve (12) M6 flat washers, and six (6) M6-1.25 nuts.
NOTE: Make sure that all bolts are tightened before proceed-
ing to the next assembly step.
