HEATER SIZING CHART
	HOW MUCH HEAT DO I REQUIRE?
EASY SIZING CHART
Cubic feet of space to be heated**	Temperature Rise Required (degrees F)*					BTU Capacity Required	* Temperature rise required is the difference between actual temperature and desired temperature.
		20 degrees	30 degrees	40 degrees	50 degrees
	5,000	14,000	20,000	27,000	34,000		** To determine cubic footage: Length x Width x Height of structure.
	7,000	19,000	28,000	38,000	47,000
	10,000	27,000	40,000	54,000	67,000		Notes: Use this size/selection chart as a guide only since buildings vary according to type of construction, tightness and insulation. When BTU requirements are less than 75% of heater's rated capacity optional remote thermostat is recommended for better efficiency.
