INSTALLATION
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. The heater must be installed in a way that doesn’t
restrict fresh airflow to the unit. The heater cannot be 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 221°F (105°C).
