SAFETY PRACTICES AND PRECAUTIONS
■ Clean the heater with caution. Avoid steam burns; do not use a wet sponge or cloth to clean the heater while it
is hot. Some cleaners produce noxious fumes or can ignite if applied to a hot surface.
■ Be sure all heater controls are turned off and the heater is cool before using any type of aerosol cleaner on or
round the heater. The chemical that produces the spraying action could, in the presence of heat, ignite or
a
cause metal parts to corrode.
■ Do not operate the heater under unprotected combustible construction, maintain clearances. Use only in well
ventilated areas.
■ Keep the area surrounding the heater free from combustible materials, trash, or combustible fluids and vapors
such as gasoline or charcoal lighter fluid. Do not obstruct the flow of combustion and ventilation air.
■ To avoid the risk of burns or accidental cloth ignition, do not touch the heater anywhere near the burner
assembly during operation.
■ Do not touch the burner assembly until after the heater has cooled.
■ Carefully monitor young children in the vicinity of any operating heater.
■ Do not hang clothing or any other flammable materials from, on, or near the heater.
■ All leak tests should be done with a soap solution. Matches should never be used for this purpose.
■ This outdoor heater is primarily used for temporary heating of outdoor patios, decks, spa and pool area, and
work areas.
■ CALIFORNIA PROPOSITION 65-WARNING: The Burning of gas cooking fuel generates some by-products which

Do not locate either the gas or electrical supply line directly over the top of the heater, due to the extreme heat
that may cause overheating or damage. The heater must be installed in a location that is accessible for service.
he heater must be installed in a way that doesn’t restrict fresh airflow to the unit. The heater cannot be
T
installed in a recessed area. Doing so may cause poor performance and heat damage to the surrounding area.
MOUNTING
Each heater must be installed so that the minimum clearance to combustibles are maintained. Combustible
materials are defined as wood, paper, foliage, plastic, plexiglass or other materials capable of being ignited and
burned. Such materials shall be considered combustible even though flame-proofed, fire retardant treated or
plastered. Additional clearances may be required for glass, painted surfaces and other materials which may be
damaged by radiant or convection heat.
ELECTRICAL
Important!
A 24 VAC, 40 VA transformer has been included with the product. It is imperative to use this transformer.
The on-off control of the heater should be controlled from 120 VAC side of the transformer (see wiring diagram).
A UL approved outdoor wall switch must be used for this purpose. The transformer must be mounted a
minimum of 12” from the heater in a weather protected cover. Do not put the transformer in the heater or
above the heater (this will damage the unit.) A step down transformer approved as having at least a 40 VA
rating must be utilized for each connected heater. Control wires used to electrically connect one or more
heaters together must have both adequate capacity and insulation temperature ratings for the total connected
load. Use at least 18 ga. wire up to 50 ft. from heater to transformer or wall switch. Use 16 ga. over 50 ft.
distance. If the original wires supplied should need replacement, they must be replaced with wiring material
having a temperature rating of at least 105 degrees Centigrade/221ºFahrenheit.
GAS PIPING
A minimum pipe size of 1/2” is required for inlet piping. A 1/2” lever handled shut-off gas cock should be
installed within 6 feet of the appliance for servicing the unit. Check with local and state plumbing and heating
codes regarding sizing of the gas lines. Installation of a drip leg in the gas supply line going to each heater is
required to minimize the possibility of any loose scale or dirt within the gas supply line from entering the
heater’s control system. A 1/8” NPT plugged test gage connection is required immediately upstream of the gas
supply connection to the heater.
