4. GAS SUPPLY:
The heater comes with a flexible hose assembly inside the post with 3/8” male flared fitting for
hook-up to a minimum 5” w.c. Natural Gas supply (7” w.c. maximum), OR minimum 11” w.c. LP
Gas (14” w.c. maximum).
The combination gas control valve in the heater has an integral pressure regulator that reduces
gas manifold pressure to the orifice and burner to 3.5” w.c. natural gas, or 10.5” w.c. propane.
The gas valve is convertible between natural gas and LP gas, but must be supplied with the gas
type that has been set for operation. See Section 5. below for conversion between gas types.
Never connect an unregulated gas supply to the heater.
Only use the gas type set for operation of the heater. Do not use LP gas if the gas
valve and gas orifice are set for natural gas, or do not use natural gas if valve and
orifice are set to operate on LP gas. Personal injury, death, and/or property dam-
age can result from using the incorrect gas.
Gas supply to this heater requires a gas pressure regulator (not supplied). Heaters may be con-
nected to a regulator individually or in zones. Gas pressure regulators must be for the correct gas
type, and properly sized for each particular installation.
For your safety a complete gas tightness check of all connections and hoses must be performed at
the installation site, prior to use.
PRESSURE TESTING OF THE GAS SUPPLY PIPING
 This appliance and its individual shutoff valve must be disconnected from the gas supply piping
system during any pressure test of that system at test pressures in excess of 1/2 psi (3.5 kPa)
 This appliance must be isolated from the gas supply piping system by closing its individual
manual shutoff valve during during any pressure testing of the gas supply system at test pres-
sures equal to or less than 1/2 psi (3.5 kPa)

9. SAFE LOCATION OF HEATER:
CAUTION: THIS HEATER IS FOR OUTDOOR USE ONLY
See also “Installation Requirements”, section 2, page 6
Locate the heater out of pathways where people may come into contact with it, or in areas where
the heater may be subject to accidental damage.
This heater can be used to provide radiant heat comfort outdoors, at poolside, spa areas, ter-
races, patios and work areas, etc. Not for indoor use. (refer to section 2, page 6)
It is necessary to provide “wind breaks”, against wind and breezes to maximize comfort.
If objects are left under a heater in operation, such objects will be subject to radiant heat.
Always maintain at least the minimum certified clearances to combustibles from the heater to any
adjacent combustible materials. Refer to Fig 12 below.
 Install heater on a level, solid and stable surface.
 Do not install in an explosive environment. Keep away from areas where gas vapours
are present or inflammable liquids are stored or used.
 In case of high winds, completely shut-off the heater and gas valve. Remove reflector
dome to secure storage if necessary
9.1 CLEARANCES TO COMBUSTIBLES MUST BE MAINTAINED:
The clearances to combustibles represent a
surface temperature of 90F° (50C°) above am-
bient temperature.
It is the installer’s and end user’s responsibil-
ity to ensure that materials with a low heat tol-
erance which may degrade at lower tempera-
tures are protected to prevent degradation.
Examples of low heat tolerance materials in-
clude vinyl siding, fabrics, canvas, plastics,
filmy materials, tri-ply, etc.
Maintain clearances to combustible materials
as shown in Fig. 12:
 Sides of Reflector: 24 inches
 Above Reflector: 18 inches
 Below Reflector: 24 inches
 Children and Adults should be alerted to the hazards of high surface temperatures and

10. ELECTRICAL REQUIREMENTS
The heater, when installed, must be electrically grounded in accordance with local codes or, in the
absence of local codes with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electri-
cal Code, CSA C22.1. All wiring and electrical connection must conform to the requirements of the
above codes.
Single heater requires 24 Vac, 60 Hz electrical transformer sized at 40 VA. If multiple heaters are
connected to a single transformer, the proper transformer is 24 Vac, 60 Hz, sized at 40 VA for the
first heater, plus 20 VA for each subsequent heaters. For example, four heaters wired together
(parallel), require a transformer of 100 VA. It is not recommended to install more than 12 heaters
per zone. PROPER WIRING POLARITY MUST BE MAINTAINED, particularly when grouping the
heaters in a zone.
Total wiring distances of up to 200' must use minimum 16 gauge electrical wire, and wiring dis-
tances of over 200' must use minimum 14 gauge electrical wire. The heater when installed must
be electrically grounded in accordance with the local codes or, in the absence of local codes, with
the National Electrical Code, ANSI/NFPA 70. Malfunction of the heating system will result if the
voltage varies by more than +10% or -10%.
The heater can be controlled by:
 The “on / off” switch located in the control cover on the heater
 An optional radio frequency hand-held remote control
 Power to the heater or zone of heaters can be controlled / isolated by a switch or switching
panel located in a secure central location
 Total load of all heaters must be considered in determining the required contact rating of
the controlling switch.
Keep any electrical supply cord or wiring away from any heated surfaces.

11. LIGHTING, OPERATION, AND SHUTDOWN INSTRUCTIONS
LIGHTING:
1. A gas hose located inside the post supplies fuel to the burner.
Prior to each use of the heater inspect any visible portion of
the hose that is exposed. If there is any damage or wear to
the exposed hose, call a qualified gas service technician to
replace the damaged hose with one supplied from the manu-
facturer.
2. An “On / Off” toggle switch is located on the control cover be-
low the burner. To turn the heater “On” (start ignition se-
quence) place the toggle switch up to the “On” position.
3. After completing a 3 second pre-purge cycle the direct spark
ignition (DSI) control generates high voltage to the spark ig-
niter, and 24 volts to energize the gas valve.
3. The Burner will light and establish a steady flame.
4. Once the flame sensor determines there is a steady flame
established, the spark igniter is then de-energized.
5. If a flame is not established during the first 20 second Trial for Ignition (T.F.I.), the unit will per-
form an inter-purge and a second T.F.I. If a flame is not established during this attempt, an-
other inter-purge and T.F.I. will be performed. If a flame is not established during the third
(final) attempt, the unit will enter the soft lockout mode. The soft lockout mode is a 30 minute
time-delay after which the unit will reset to try to ignite the gas again, as in normal operation,
and will repeat the T.F.I. sequence.
6. If there is a loss of flame during the run mode, the unit will energize the spark within 0.8 sec-
onds and perform a T.F.I., without the gas valve being closed first, this is called Spark Resto-
ration. If a flame is not established during Spark Restoration the unit will repeat the process in
step number 5 (above).
10. If a flame is present with the Gas Valve de-energized the unit will enter a hard lockout mode.
If there is an internal fault detected within the control, this will also cause hard lockout. Any
hard lockout will require service by a qualified service person.
SHUTDOWN:
1. An “On / Off” toggle switch is located on the control cover below the burner. To turn the heater
“Off” place the toggle switch down to the “Off” position.
2. If the heater will not be used for some longer time period, or requires service, shut off the elec-
trical and gas supplies to isolate the heater.

12. MAINTENANCE
1. Prior to each use, inspect the heater for damage - a qualified gas service person must repair
or replace any damaged or malfunctioning components as supplied by the manufacturer.
2. Periodically (monthly) perform a leak test of all visible gas connections to ensure safe opera-
tion - see page 12 for leak test procedures
3. Annually inspect the gas hose that is concealed inside the confines of the post. Refer to the
assembly instructions (pages 10 -11) in reverse order to expose the hose for inspection. If
there is evidence of excessive abrasion or wear, replace the gas hose or any worn or defective
components only with replacement parts available from the manufacturer.
4. Reassemble the heater and leak test all connections as instructed on page 12.
5. Keep the appliance area clear and free form combustible materials, gasoline and other flam-
mable vapors and liquids
6. Ensure that there is no obstruction to the flow of combustion and ventilation air
7. Visually inspect the burner flame performance.
 The burner area is likely to attract spiders, especially inside the orifice. Annually before
the heater is put into service, the heater should be inspected by a qualified gas service
technician for spider webs, insects, and debris around burner and orifice. A plugged in-
jector or orifice will obstruct the gas flow to the burner. This will result in burner malfunc-
tion and possible damage.
 A heater that is operating properly will produce a relatively uniform ‘orange glow’ over
the surface of the emitting mantel. (Caution: Wind conditions can cool portions of the
emitter surface below the temperature of the visual spectrum.)
 A poorly performing burner will exhibit uneven ‘orange glow’ at the bottom of the mantle,
and the top portion of the mantle will be dark (below the visual spectrum temperature)
 Other indicators of poor burner performance are:
 A gas ‘smell’ combined with yellow tipped flames on burner
 Heater does not provide expected heat output capacity
 Burner makes small popping sounds while operating. Note: When heater is warming
up or cooling down a pinging metallic noise is normal.
 A heater in this poor performance condition requires service by a qualified gas service

The 4N/L-51/62-24, 44N/L-5/6-24 Patio Heater
direct spark ignition, sequence is as follows :
13. SEQUENCE OF OPERATION - GASLITER MICRO 50N IGNITION CONTROL
1. 24 volts supplied to the DSI control initiates the 3 second pre-purge cycle.
2. After completing the 3 second pre-purge cycle the DSI control generates high voltage to the
Spark Igniter, and 24 volts to energize the Gas Valve.
3. The Burner will light and establish a steady flame.
4. Once the flame sensor determines there is a steady flame established, the spark igniter is
then de-energized.
5. If a flame is not established during the first 20 second Trial for Ignition (T.F.I.), the unit will
perform an inter-purge and T.F.I. If a flame is not established during this attempt, another in-
ter-purge and T.F.I. will be performed. If a flame is not established during the final attempt,
the unit will enter the soft lockout mode. ) (The soft lockout mode is a 30 minute delay time
after which the unit will reset to try to ignite the gas again as in NORMAL OPERATION
6. If there is a loss of flame during the run mode, the unit will energize the spark within 0.8 sec-
onds and perform a T.F.I., without the gas valve being closed first, this is called Spark Resto-
ration. If a flame is not established during Spark Restoration the unit will repeat the process in
step number 5 (above).
7. If a flame is present with the Gas Valve de-energized the unit will enter a hard lockout mode.
If there is an internal fault detected within the control, this will also cause hard lockout. A
qualified gas service person is required to repair or replace defective components with parts
from the manufacturer.

 Refer to trouble shooting guide page 28
8. Periodically clean the heater with a mild detergent solution and rinse with clear water, or use a
commercially available specialty cleaner. In particular keep the surface clean and clear at the
base of the burner where air is taken in for combustion.
A complete replacement parts list is on page 29. Replacement parts are available from a local dis-
tributor in your area. Contact information for the manufacturer is available inside the front cover of
this manual.

15. OPTIONAL 24 Vac PATIO HEATER CONTROL PANEL
This panel and all heaters in the system must be installed and grounded in accordance
with all applicable local and national codes.
Each panel is supplied with switches for 4, 8 or 12 zones (maximum two heaters per zone).
Total wiring distances must be considered and low voltage wire correctly sized to suit the total
VA rating of the transformer. All low voltage wire must be adequately sized for the total
load - total wiring distances up to 200 feet must use minimum 16 gauge electrical wire,
and wiring distances over 200 feet must use minimum 14 gauge electrical wire.
Confirm the electrical wiring system capacity with ALL heaters ON under full load by taking volt-
age readings at the ignition module terminals of each heater . To avoid system malfunction,
the voltage range must be within 21.6 volts to 26.4 volts (± 10%). Also ensure proper po-
larity.
The patio panel allows for ‘On/Off’ control of up to 4, 8 or 12 individual heaters or zones of heat-
ers (two heaters per zone max.). If a thermostat is to be incorporated in the system, it must be
installed in the circuit between the panel and the heater(s). Total load of the heaters being con-
trolled must be considered in determining the contact rating of the thermostat.
If the installation provides an individual transformer for each heater, size each of the 24 Vac,
60Hz transformers at 40VA. A single transformer sized for a multiple heater installation, requires
40 VA for the first heater only, and 20 VA for each additional heater.
Example: 5 heaters wired in parallel require a calculated 120 VA (40 + 20 + 20 + 20 +20) -> se-
lect the closest rated transformer HIGHER than the calculated 120 VA = 150 VA.
The best mode of control for each individual heater is by “ON/OFF” switch. If a thermostat is to
be incorporated into the system it must be installed downstream of the control panel.
For central control of patio heater installations:
Patio heater control panels are available with switches for 4
zones (PCP-4), 8 zones (PCP-8), or 12 zones (PCP-12). At
most, one switch can control maximum two heaters in a zone.
The panel is designed to be surface mounted INDOORS only,
and preferably located in a secure staff area, beyond the reach
of patrons.
WARNING
Must be used for low voltage (24V) wiring only. To avoid
system malfunction, PROPER WIRING POLARITY MUST
BE MAINTAINED.
