Owner’s Manual

Before Starting Your Heater

Before you start your heater examine the heater

installation to determine that:

• Areas immediately around the heater including the
air inlet and flue areas are free from obstructions.

• Physical support of the heater is sound.

• There is no obvious deterioration of the heater.

Starting and Shutting Down Your Heater

Sunpak utilizes an automatic ignition system. Follow

these important safeguards.

• Never attempt to manually light the burner with a
match or other source of flame.

• Read and follow the operating instructio ns on the
inside of heater door especially the item that reads
as follows:
Wait 5 minutes to clear out any gas. Then smell for
gas. If you smell gas follow the instructions on the
front of this manual regarding gas leaks. If you don’t
smell gas, go to the next step.

• If a suspected malfunction occurs with your ga s
control system, such as the burner does not light
when it should, refer to the section ‘Shutting Down
Your Heater’.

Sunpak® Infrared Heaters

Starting Your Heater

Turn gas and 24 VAC electrical power “ON”. The pilot and
burner should light within 4 seconds. A flame sensor will
shut off the spark. If the burner does not light within 15
seconds the flame sensor will shut “OFF” the gas valve. To
relight the pilot and burner, shut “OFF” power. Wait 5
minutes. Turn power back “ON”.

If the heater will not light, turn the manual gas valve to
“OFF” position and the electrical switch “OFF” to the heater
and call your quality service agency or gas supplier.

Shutting Down Your Heater

Turn electrical power to the heater “OFF” .
Should you need to shut down your heater for service or
maintenance, the manual gas valve next to the heater
should also be turned “OFF”.

Performing Routine Maintenance

Overtime, particularly during long periods of disuse, the
heater can accumulate dirt and debris in and around the
pilot and the burner. Routine maintenance should be
performed at least once a year by a qualified service
agency to insure the heater is operating properly. More
frequent service may be required for heaters located near
waterfronts.

Stainless Steel Heater

Stainless steel does not “rust”; however air pollution can
leave brown deposits on heaters. We recommend washing
the outer stainless steel casing only with a mild detergent
solution and wiping it dry with a soft cloth to bring back the
original shine. The stainless steel may be expected to
permanently darken around the top of the heater over time
with extended use.

Before You Remodel

Should you plan to make any changes to the patio or
building structure after heaters have been installed, your
heater installation must be reviewed by a qualified agency
to insure that clearances from combustion material and
ventilation requirements are maintained after alterations are
complete. When plastic curtains or drops are used to
enclose a patio you must take steps to insure that Sunpak
heaters have the required permanent access to outside air.
If a patio is to be partially enclosed a qualified agency
familiar with this type of heating equipment must be
consulted to insure the safe operation of this equipment.

Heater Layout and Design

Sunpak® heaters were specifically designed to provide
heated comfort in an outdoor environment. They have
been used on outdoor patios across the United States and
Canada for over 20 years. When properly integrated into a
patio design, Sunpak

heating effectiveness will depend on air temperature, wind
velocity and other factors. Whenever possible local

utilized vary greatly. As an outdoor rated heater it has
passed basic wind and rain tests. This does not mean the
heater cannot be damaged by the environment or when
operated in very windy conditions. For this reason it is
strongly suggested that heaters be inspected and if
necessary repaired annually or before each heating
season.

general by necessity and may need to be refined for local
conditions. These guidelines are to be used in

Breezy conditions must be considered when heating any
patio. Windbreaks can be extremely effective in increasing
comfort and reducing heating costs. Windbreaks must be
designed in such a way to allow for the necessary fresh air
and ventilation for proper heater operation (see ventilation
of installation section).

WARNING

Asphyxia / Carbon Monoxide

Heater requires adequate combustion air and
ventilation in order to operate safely. Improper
ventilation can generate carbon monoxide or
other harmful gases that could result in death
or breathing difficulties. Small or enclosed
patios may not be appropriate to for this type
of heater.

Sunpak heaters must always be operated in a location
that allows uniform air pressure around the heater. If only
part of the heater is located in a wind protected zone
damage to the heater may occur. Time should be taken to
observe how the wind will affect the heaters under local
conditions.

Caution

Heater placement is critical for effective and efficient
patio heating. If heaters are placed too close together or
mounted too low, people become uncomfortable. If
heaters are placed too far apart on a breezy, wind-swept
patio the patio may never get warm.

that the top clearances required from combustible material
increases when heaters are at any angle. The heater must
always be horizontal to the floor.

Fire and Explosion

Proper clearance for combustible materials must be

maintained. See installation section of this manual

for required clearances for different model and

mounting options.

Sunpak heaters may be laid out in a number of
configurations depending on the structural constraints of
the patio and heating requirements. One approach is to
face heaters straight down over the table and seating
areas. Another approach is to locate heaters to the side
and to angle them inward. A third approach is to cluster
the heaters in the center of the patio and angle heaters
outward. It all depends on the needs of a particular patio.

Damage to Heater

Failure to operate heater in a uniform air
pressurize environment or under erratic wind
conditions can cause over-heating of controls,
and damage to the front grill and burner.

Temperature Control

A thermostat can be incorporated into the electrical
circuit; however this may not be the best means of
temperature control. Because the infrared heat warms
people and objects, when used outdoors the heater may
not increase the air temperature and thus the thermostat is
never satisfied.

When multiple heaters are used it is suggested that they
be put on individual switches to provide flexibility in
heating. Typically all the heaters would be turned on to
heat a cold patio, and then heaters would be turned off
selectively as people settle in. A timer or master switch
may be convenient to ensure the heaters are not turned on
when the patio is not in use.

MINIMUM CLEARANCE FROM COMBUSTIBLE MUST BE MAINTAINED (see chart opposite page

SUNPAK will raise the comfort level 5-10º Fahrenheit
outdoors. The above coverage table was based on
still breeze conditions. Under windy conditions more
heat will be required. It is recommended that a
windswept patio be designed with wind breaks to
stabilize the patio environment. Wind breaks shall
NOT interfere with the ventilation of combustion air
requirement of the heater(s).

ANGLE MOUNTING: Most models of the SUNPAK
heater may be angle-mounted to a maximum of 30º
to accommodate mounting the heaters around the
edges of the patio. Note that the top clearance to
combustibles increase when heater is tipped from
the horizontal.

NOTE: Local codes may have special requirement
regarding head clearance requirements. Some local
codes require all portions of overhead radiant
heaters to be located at least 8 foot above the floor.
