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

®

 heaters generally increase the 

comfort level 5 to 10 degrees Fahrenheit outdoors. The 
heating effectiveness will depend on air temperature, wind 
velocity and other factors. Whenever possible local 
Sunpak

®

 installations should be reviewed to determine the 

effectiveness for regional environments. 

The environments in which Sunpak

®

 heaters are 

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. 

The variable environments in which Sunpak

®

 heaters 

are applied means that these general guidelines are 
general by necessity and may need to be refined for local 
conditions. These guidelines are to be used in 
combination with the installation instructions. 

Patio Design Consideration

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. 

Sunpak

®

heaters work best if they are placed in areas 

of the greatest heat loss, such as the open side of a semi-
protected patio area. The Sunpak

®

heater may be 

mounted at up to a 30 degree angle or face down. Note 
that the top clearances required from combustible material 
increases when heaters are at any angle. The heater must 
always be horizontal to the floor. 

WARNING 

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. 

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

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.
