SUNPAK Layout & Design

SUNPAK will raise the comfort level 5-10 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 30 deg. to accommodate mounting the heaters around the edges of the patio. Note that the top clearance to combustibles increases when heater is tipped from the horizontal.

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

Appliance Design

SUNPAK’s aluminized or stainless steel enclosure, together with the aluminum face grill, provides resistance to wind and rain. SUNPAK’s slim body design (8 x 8 x 48 inches) and 0 to 30 degree angle mounting option on most models, gives SUNPAK the versatility to fit easily into a wide variety of patio situations. An optional mounting kit (part no. 12006) is available.

The SUNPAK hanging patio heater is design certified by the CSA International as an unvented infrared heater for outdoor or indoor (commercial) installation. All units are equipped with spark ignition and 100% shutoff for safety, economy, and convenience.

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.

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).

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.

Warnings

! WARNING

Fire and Explosion
Proper clearance for combustible materials must be
maintained. See installation section
for required clearances for different model and
mounting options.

 

! 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.

 

! Caution

Damage to Heater
Failure to operate heater in a uniform air
pressurized 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.
