Any spider webs, nests or debris can be cleaned with a
straight piece of wire and wire brush.
You may use a vacuum cleaner. Never use wood or plas-
tic toothpicks to clear ports or other openings, because
wood and plastic can break and block the ports.
BURNER ASSEMBLY INSTALLATION :
Install the burner assembly by reversing the aforemen-
tioned burner assembly removal. Upon completion of
burner assembly installation, make sure it is in the center
of the emitter support pan. Now install and secure the
emitter and reflector assembly.
After reassembly, check the burner gas connection for
leaks and then test fire heater. Observe the main burner
flame pattern. It should appear as shown in the following
figure and the flame color should be blue with slight yel-
low tipping. If flames extend more than 1/2 inch beyond
surface of the emitter screen or black soot is accumulating
on the emitter screen, the heater should be turned off
immediately. The heater should not be operated again
until repairs are made by a qualified service person.

TEST FIRING HEATER :
Test fire your patio heater, following the lighting instruc-
tions applicable to the gas control system employed.
Leak test all gas connections with soap solution. Soap
bubbles indicate gas leakage. DO NOT use a match or
flame to test for gas leaks.
Alternate Propane System :
Could be connected to a
20 lb. Propane (LP) gas cylinder, providing the gas
system is installed by a qualified service person. Gas
cylinder must be constructed and marked in accordance
with specifications of the U.S. Department of
Transportation for Propane Gas Cylinders and must also
be equipped with the following :
• A collar to protect the propane gas valve.
• A shutoff valve terminating a propane gas cylinder
valve outlet QCV-Type 1.
• A safety relief valve having direct contact with the
vapor space of the tank.
• An arrangement of vapor withdrawal.
• An approved hose and adapter must be used without
alteration.
• Turn heater gas control knob and gas cylinder valve to
“ OFF” position.
• Propane cylinder equipped with the new style QCV
valve is equipped with right handed threads.
• Propane cylinders have a bleed-off valve. This valve
should be inspected for leaks after each filling of the
cylinder. Turn clockwise to reseal.
• Fasten full propane cylinder to a table beneath the patio
heater and connect an approved hose and adapter
assembly to cylinder valve and heater regulator inlet
fitting by turning clockwise.
With heater gas valve still in the “OFF” position, turn ON
tank valve and check for leaks with soap solution.
A LP Cylinder enclosure, if provided by the consumer, must
conform to the following:
a. One side of the enclosure shall be completely open; or
b. For enclosure having four sides, a top and a bottom, shall
have at least two openings at cylinder valve level and two
openings at floor level and not less than a total free area of 10
square inches at valve level and floor level. Every opening
shall have minimum dimensions so as to permit the entrance
of a 1/8 inch diameter rod.
c. Cylinder valves shall be readily accessible for hand
operation. A door on the enclosure is acceptable.
d. A minimum clearance of 2 inches between the lower surface
of the floor of the Lp gas supply cylinder enclosure and the
