Please note the following very important safety precautions:
!!! Children and adults should be alerted to the hazards of high surface temperatures of
the main burner and reflector and should stay away from these areas.
!!! Children should be carefully supervised when near the heater. This heater is not a
toy and children should not be allowed to push, climb on, or swing on the heater.
THESE ACTIONS COULD CAUSE SERIOUS INJURY, PROPERTY DAMAGE, OR
DEATH.
!!! Clothing or other flammable materials should not be hung from the heater and/or
placed near the heater during operation.
!!! Installation and repair of the heater should be done by a qualified service technician.
The heater should be visually inspected before each use and at least annually by a
qualified service technician. Certain weather conditions such as being near the
ocean, dusty areas, areas with high humidity, areas with high wind conditions, and
heavy use, may require more frequent cleaning or maintenance. When in doubt call a
qualified service technician. It is imperative that the control compartment, burner
system, and circulating air passages of the heater be kept clean.
!!! Any part, sub-assembly, or component removed for cleaning or maintenance must be
properly re-installed before using the heater.
Some basic use and maintenance instructions:
!!! Be sure to keep the area where the appliance is being used free from combustible
materials, gasoline, and other flammable materials.
!!! Please be sure there are no obstructions near the heater head.
!!! The appliance is operating properly when there is a nice cherry red glow (seen better
at night) coming from the emitter grid starting two to three inches from the bottom of
the emitter grid. Wind gusts will affect and possibly disrupt the glow and flame
pattern. The heater should not be operated in windy conditions over 5 – 7 MPH. If
you can protect the heater from wind gusts it will operate far more efficiently.
Operating the unit in severe wind or dusty conditions will affect the burning
characteristics, may create soot on the emitter grid and burner, and possibly clog the
pilot or main burner orifices.
!!! The heater post, base, and reflector, may be cleaned with basic soap and water and
mild household cleaning products, car wax, or commercially available stainless steel
cleaners. Never attempt to clean the emitter grid radiant with any cleaning solutions
or abrasive materials. Never spray the emitter grid or heater head assembly with
water or other liquids, as it will damage the radiant, burner, valve, and ignition
system. These parts are constructed of commercial quality stainless steel and brass
and require no cleaning. Occasionally, you can gently brush the emitter grid with a
small non-abrasive brush to remove excess soot that may have accumulated on the
emitter. If the emitter grid shows sooting you may have to remove the emitter grid
and clean the burner head as well.
!!! It is absolutely imperative that this heater only be used OUTDOORS and in a
well-ventilated space and shall not be used in a building, garage, motor vehicle,
recreational vehicle, boat, tent, or other enclosed areas. This is an un-vented heating
product and creates by-products of combustion that can cause injury and possibly
death.

Technical Data: Model NPC05
This unit is designed and configured
for use with Natural Gas Only.
Fuel: Natural Gas
Heating: Each Patio Comfort heater will cast a 10-
12 foot circle of sun like radiant heat. Heat output
will vary based on “wind chill” factor, outside air
temperatures, altitude, prevailing wind conditions,
and location of heater.
Infrared heaters utilize virtually 100% of the
fuel/energy they consume to produce clean draft-
free warmth. Infrared heaters do not waste
precious energy by trying to heat the air.
Infrared heat works like the radiant rays of the sun
and will directly heat objects near them such as
people, tables, chairs who in turn will absorb the
heat and reflect it. The push button Piezo ignition
system is used to light the pilot flame first. After the
thermocouple device allows gas to flow to the main
burner head you may then safely engage the main
burner system by turning valve control knob to “ON”
Setting.
Pressure: The unit is equipped with an external
Natural Gas Regulator (supplied with heater) preset
to 4.5 Inches Water Column. This specially
designed regulator, fuel line, and natural gas
fuel source shut-off kit must be used with this
appliance. Hose, couplers, and shut-off
components are CSA (AGA) approved and should
meet all local codes and ordinances in U.S. and
Canada. Check your local codes agency if you have
any questions. Complies with ANSI Z 21.54
Maximum: pressure Natural Gas ½ psig

Function of Heater
After the main burner is lit the burner will radiate
heat in a 360-degree circle. The circle of warmth
will vary dependent on outdoor temperatures, wind
chill factor, area protection, and other variables.
The average heating area is approximately a 10-foot
ring of warmth. The reflector will return upwardly
radiated heat downwards. On first use please allow
heater to burn a few minutes to burn off machining
oils used in the production of the heater.
Pleasenote: Upon first using the heater, not
using the heater for an extended period, or
after re-attaching the 12 foot hose to the
unit, it may be necessary to depress the
control knob at the “PILOT” setting up to
two minutes to purge the air in the hose and
fuel lines before the PILOT flame will ignite.
Please be patient, this is all part of the safety
system that has been designed for your
protection.
Assembly Tips
For your convenience and safety the Patio Comfort
outdoor patio heater has been almost completely
Assembled. The burner head and valve assembly
have been fire tested for added safety.

Assembly Instructions for Patio Comfort
Natural Gas Patio Heater Model NPC05
Please be sure to read all instructions thoroughly before attempting to assemble or use your
Patio Comfort Natural Gas outdoor infrared patio-heater. Before using your heater please
read the safety warnings and safety tips. This is a gas-burning appliance that gets extremely
hot at the emitter grid. If you have any questions about the final assembly, connections to the
fuel source, leak testing the fittings and connections, operation, or function of this appliance
please contact your selling dealer or a qualified gas service technician or local natural gas
public utility before attempting to operate this appliance.
We have tried to make the assembly of your Patio Comfort Natural Gas heater as simple as
possible while maintaining the highest levels of safety and performance.
The installation of this product must comply with local codes or authority having jurisdiction.
In the absence of local codes the installation must comply with the ANSI Z223.1 1984 entitled
the “National Fuel Gas Code.” In Canada, in the absence of a local building code requirement
it must comply with the National Standards of Canada CA/CGA-B149.1 & 2 M86.
Your Model PC-NG base has been pre-assembled at the factory. The base assembly includes
a heavy cast-iron ballast. Under no circumstances should the ballast weight be removed from
the base or altered in any way. This ballast weight provides for added safety and stability.
Your heater should not be operated in rain, high winds, or dusty conditions. In high wind
areas you might want to remove the reflector to minimize the potential danger of the heater
blowing over when not in use. Infrared heaters, or any outdoor gas burning appliance, are not
designed to operate in windy conditions over 5 – 7 MPH.
Step 1: Lay base on floor or sturdy table with socket assembly in vertical upright position.
Slide the 66” long stainless steel or painted post with rectangular access hole at the
bottom of the post over the round welded vertical socket on the base.
© AEI CORPORATION 2005 11
Align the post holes at the
bottom of the post with the
holes in the vertical socket
assembly. (See Figure #1)

Step 5:
If the 3/8” x 3/8” flared brass fitting
is screwed into the shorter feed line
hose please remove it at this time
and attach this fitting at the base
of the heater head. Tighten
securely. Do not use any
pipe sealant at this brass to
brass connection. Do not
over-tighten.

Step 6:
Insert shorter feed line hose in
through rectangular access hole at
the bottom of the post and feed it
out the top of the post. Make sure
end of hose and regulator feed line
assembly is visible through
rectangular access slot at bottom of
post. This assembly has been pre-
assembled for you and leak tested.
Just to be safe, we will ask you to
leak test and double check all
fittings before using your new
heater.
(See Figure #6)
Step 7:
Secure head to feed line at this
time. Be sure the 3/8” x 3/8” flare
brass fitting is tight where it
connects to the fitting at the base
of the heater head as well as at
the hose swivel fitting.. No
sealant is required at these
fittings. Do not over-tighten.
Brass to brass is an excellent
connection. Do not secure
head to post at this time.

At this point we need to stop assembling the heater and test for any possible gas leaks in the
regulator assembly and head to feed line connection. In order to achieve the leak testing we
must attach the twelve-foot hose and couplers to the gas supply. If you are not comfortable
either hooking up the valve at the gas supply line or leak testing the unit you should contact a
licensed plumber, gas technician, or public utility.
© AEI CORPORATION 2005 14
Step 8:
1) Since there are a variety of possible gas supply
configurations our directions can only be
general in nature.
2) First, shut off the flow of gas to the stub.
3) This can be accomplished at the stub if you
have a shut off on your stub. If not, you will need to shut off the gas at
its source to your stub.
Fi
g
ure #8
4) Attach the combination coupler/shut off valve onto your ½” gas line.
Your line may be larger than ½” so it must be reduced to ½” in order to
attach the shut-off valve. This is a very safe and convenient system so
please do not try to modify it in any way,
5) Use an approved pipe sealant or Teflon Gas tape to seal the connection
from the stub to the shut-off valve. (See Figure #8)
Step 9:
1) With gas still shut off. Insert one of the 3/8” male nipple fittings at end
of the 12 foot hose into the coupler at the end of the
shut-off valve/coupler.
Fi
g
ure #9
2) You can engage and disengage the couplers
by just sliding the ring back at the end of the
coupler. The male nipple at the ends of the
hose should insert and disengage easily.
3) The couplers can only work one way. When
the unit is not in use you can leave the hose
attached to the heater or you disengage the
hose set either at the heater or at the fuel
supply or at both points. (See Figure #9) Please try to position the
hose so that it does not present a trip hazard.

Step 10: (See Figure #10)
© AEI CORPORATION 2005 15
Testing For Gas Leaks
1) The hose should be properly engaged at the
quick disconnect coupler at the post and at
the house supply. Please turn the supply of
gas ON.
2) Using a soapy solution carefully check each
and every fitting, quick coupler, and gas
connection. Perform the leak test from the
valve to your house gas supply all the way to
the connections at the post. Also check where the fittings at the feed
line hose is attached to the heater head. You should do this with a
soapy water solution. There should be no open flames or other sources
of ignition near you when performing the leak test.
Fi
g
ure #10
3) Never do the gas leak test with an open flame!
4) If you see bubbles at any connection you have a leak. Shut off gas at
the source. This leak must be remedied before going any further.
Please re-tighten leaking fitting and once again check with a soapy
water solution. Most leaks are the result of not tightening the fittings
adequately.
5) If you cannot stop the leak you should shut off the gas immediately at
the shut-off valve and re-check your assembly. If you are still having
trouble achieving a gas tight connection you should call your Patio
Comfort dealer or qualified gas technician. All the of the key fittings
and components are high quality brass fittings and have been pre-test
ed at the factory.
Step 11:
Figure #11
If your unit passes the gas leak test 100% you
can now secure the access panel at the
bottom of the post with the four self-tapping
pan-head screws provided.
(See Figure #11)
Step 12: Figure #12
Before the last assembly step of securing the
head to the post, align the head and post and
the gas inlet to minimize any possible trip
hazards. Always try to position your heater
and hose in a way as to minimize trip hazards.
(See Figure #12)

Step 13: Figure #13
You can now attach the heater reflector
with the three 8 mm flat washers and wing
nuts provided.
(See Figure #13)
Fi
g
ure #14
Step 14:
Be sure the to attach the blue colored
protective rubber plug onto the fitting
before inserting it into the gas inlet
in the post. The blue plug is designed to
keep insects, dust, debris, moisture, and
other contaminants out of the feed line,
valve assembly, and pilot assembly.
(See Figure #14)
Figure #15
Always be sure to use the dust plug when the heater is not in use.
(See Figure #15)
Please Note:
The end of the hose set that attaches to your
home natural gas supply also has a quick
disconnect coupler and state of the art shut-
off safety valve for your safety and
convenience. As an added feature when the
“ON and OFF” black control knob on the
shut-off valve is in the “ON” position you
cannot inadvertently remove the hose
from the coupler while the heater is in
operation.
(See Figure #16)

This hose, coupler, and shut-off valve assembly comply with all UL standards. DO NOT
attempt any modifications to this hook-up.
You have now finished the assembly of the heater. We have tried to design your Patio
Comfort heater with the finest materials and safety systems available. Please do not try to
modify any part of the product, the feed line assembly, natural gas regulator, or quick
disconnect connections.
These are high quality components designed to provide you with
maximum convenience and flexibility and more importantly to
maximize the safety to you and your family.
Our unique double quick connect system allows you to safely detach the hose set from the
heater when not in use. If your dealer has not included this hook-up kit with your heater go
back to the dealer and insist that they provide it to you. The hose kit is an integral part of the
heater and will add greatly to the safety and convenience of the product.
!!!! Remember any hose can be a potential trip hazard and
should be positioned in a way where it presents the least
potential trip hazard. The hose can be easily removed from the
heater using the quick couplers included. Never attempt to
move the heater while it is in operation.

Before using your heater for the first time please review the following:
!!!! NEVER RUN THIS APPLIANCE ON PROPANE FUEL OR
ATTEMPT TO CONVERT IT TO PROPANE OR LIQUIFIED
PETROLEUM FUELS. THIS HEATER IS ONLY DESIGNED
TO BE OPERATED ON NATURAL GAS.
THIS PRODUCT CANNOT BE CONVERTED TO PROPANE GAS.
Please keep in mind that every time you connect your heater for the first time and every time
you reconnect the 12-foot hose to the heater you must first bleed the air from the fuel feed line
and hose. This is done by turning on the gas at the source and turning the valve at the heater
to the “PILOT” position.
You may need to depress the valve control knob on the heater in the PILOT position for at
least one to two minutes to bleed the air before attempting to light the PILOT light with the
ignitor.
The safety pilot system has a very small orifice size and it may take up to two minutes to bleed
all of the air out of the line. After purging the air, depress the igniter button and you will hear
the pilot light. You can also visually see it through the vents in the base of the heater head or
through the small access hole with cover plate on the base of the heater head.
AFEW WORDS ABOUT NATURAL GAS:
First of all, natural gas is a safe, clean, convenient, and cost-effective fuel. You will never
have to worry about running out of fuel for your natural gas heater in the middle of an outdoor
event.
The heater is set to operate 4.5” W.C. No attempt should be made to modify any of the
components included with your Patio Comfort natural Gas heater.
In most areas of the U.S. and Canada, natural gas pressure in residential settings is adequate
to fuel patio heaters, outdoor gas grills, gas lights, pool heaters, etc. In some of the older
areas in the West, parts of New England, and the Mid-Atlantic areas gas pressures may be too
low to allow for this product (or any natural gas appliance) to operate at its full performance
levels. If you feel that this may be the case in your home you should first check with your
local natural gas public utility. You may have to run a larger fuel pipe to adequately power this
and possibly other backyard cooking, heating, or decorative natural gas burning appliances.
If you have inadequate gas volume using multiple appliances at the same time may impact the
heat output or performance of the various appliances.
We have designed this heater to provide you and your family with many years of use. If you
have any questions whatsoever about the assembly, installation, or use of this product please
contact your selling dealer or distributor before using this product.

Placement of the Heater
Your Patio Comfort outdoor patio heater is designed for use as temporary comfort heating for
your outdoor patio, outdoor decks, outdoor spa areas, pool areas, and other outdoor areas
with plenty of fresh air.
The heater is NOT designed, approved, or intended for indoor use or enclosed area use such
as a garage, commercial building, basements, tents, ice fishing tents, prefabricated buildings
or enclosures or other enclosed areas.
The heater is also not designed for use on moving objects or vehicles such as houseboats,
yachts, travel trailers, boats, or other moving devices or vehicles.
The minimum clearances from combustibles must be maintained at all times. We recommend
the heater be no closer than 27 inches from any combustible vertical or horizontal wall or have
any combustible material within 20 inches of the top of the reflector.
“Combustibles” include Lattice, Wood, Plants, Umbrellas, Canopies, Awnings, or other

These minimum clearances from combustible materials must be maintained at all times when
the patio heater is in operation.
The heater must always be used on firm, level, and stable ground. Never move the heater while
it is in operation. Never try to hook up multiple feed line hoses together.

Lighting Instructions
Before turning on the natural gas fuel supply, visually inspect the hose assembly for evidence of excessive
abrasion, cuts, cracking, animal damage, or unusual wear and tear. If the hose leaks do not attempt to use the
heater, replace the hose immediately. Only use replacement hoses and other parts as specified by Patio
Comfort.
Before Lighting
If attempting to relight a hot heater, always wait at least five minutes. The main heater components such as
the emitter grid, gas hook up, and pilot assembly should be checked at least every two years by a qualified
service technician or immediately if you feel the appliance is not working properly.
To Light Heater
1) Be sure the control knob on the heater head is in the “OFF” position.
2) Turn the shut off valve at the house connection in a counter-clockwise direction to open. Be sure the
quick connect couplers at the heater post and end of the hose at the shut-off are fully engaged and tight. If
the couplers are not properly engaged, no gas will flow to the heater.
3) Gently depress the control knob on the control panel and rotate it counter clockwise to the “PILOT”
position.
4) This is very important!Gently depress the control knob and hold the control knob to begin the
flow of gas to the burner pilot assembly. Depress the control knob in the “PILOT” position for up to 2
minutes on new installations or reconnected hoses. This is how long it might take for the air to be
purged from the hoses and feedline delivery system. It will take less than 10 seconds for regular relighting.
Do NOT continually press on the igniter while you are purging the line. This will only cause premature
wear and tear on the ignition and weaken the charge created by the piezo ignition. Occasionally depress
the igniter and you will hear when the pilot light ignites.. You can also see the pilot light through the pilot
access port that has a small rectangular cover at the base of the heater head. This is essentially the same
safety system that you have on your water heater. Please be patient with this process. You can also hear
the pilot light when it lights.
5) Once the pilot is lit, continue to depress the control valve for about 20 seconds or until the pilot flame
remains lit after the control knob is released.
6) The burner may now be turned on to the full “ON” position for maximum heat output or it may be turned
back to the “PILOT” position to reduce heat output and fuel consumption. If you turn the control knob all
the way back to the “PILOT” position, the main burner will go off and the pilot flame will remain lit. You can
now re-ignite the main burner directly from the “PILOT” position. On the first use, a little smoke is to be
expected. This is machining oils being burned off.
The heater is designed to be operated in the full “ON” position only.
Turning the heater down will result in incomplete combustion and
sooting of the burner and very low heat output. You can immediately
re-light the main burner when the standing pilot is on.
