Includes portable Dwyer Magnehelic© Draft Gage with large 4" dial instead of No. 171 Inclined Draft Gage, 0 to .25" W.C. range in .01" divisions. Accurate within 4% of full scale. Also has air velocity scale with 800 to 2000 F.P.M. range. No leveling necessary; no gage oil required. Kit is otherwise identical to No. 1200-A, Weight only 7 lbs. 5 oz. Optional kit available with 0 to 0.5" or 0 to 1.0"W.C. Magnehelic© AV Gage; contact Dwyer.
Optional: On special order, the portable Dwyer No. 460 Air Meter may be substituted for the No. 171 Inclined Draft Gage. The Air Meter has a direct reading dual scale with high range of .05" to 1.0" W.C. and low range of .005" to .09" W.C. Low in cost, it also has air velocity scales with total range from 260 to 4,000 feet per minute.
Guesswork does not pay. Kit includes this easy-to-use Dwyer Slide Rule Computer. It gives you and your customer visual proof of heating plant efficiency.
The Dwyer Combustion Test Kit is quick and easy-to-use. With it, you can measure all four factors that govern overall efficiency: CO2, content, draft, stack temperature and smoke. Accuracy to ± % CO2, fully meets the requirements of the professional Heating Engineer. Yet an apprentice can follow the simple, illustrated step-by-step instructions.
CO2 CONTENT: To a large extent, the efficiency of a boiler or furnace depends on the amount of air supplied to the combustion chamber. Too little air causes smoke. Too much air wastes heat up the stack. Testing fuel gases for CO2 content gives you an instant, exact measure of combustion efficiency. A high CO2 reading - 8% to 12% - shows high efficiency. A low CO2 reading indicates low efficiency or too much air. The Dwyer CO2 Indicator reveals the situation accurately.
SMOKE: As you adjust a clean fire toward a higher CO2 reading, you will reach the smoke point. By inserting filter paper in the intake of the Dwyer Smoke Gage Pump, you can take a sample and match it with the Smoke Chart included. The chart facilitates balancing the burner for maximum CO2 with minimum smoke. While conforming with ASTM D-2156-XX standards for distillate fuel smoke density, this Smoke Gage can also effectively test any gas or wood burner.
DRAFT: The Dwyer Draft Gage furnishes a continuous reading of the draft and instantly shows the slightest change as you make adjustments to increase efficiency.
STACK TEMPERATURES: Quickly determined with the Dwyer Stack Thermometer included.
THE RESULT: A DEFINITE EFFICIENCY RATING: When you have finished checking the installation you will have raised the CO2 content as high as possible without causing a smoking fire … you will have the draft control set to provide about .02" or .03" water draft over the fire … and you will have a stack temperature of about 500° to 600°F. At this point, you transfer the first and last of these figures to the Dwyer Computer and read out the percentage of efficiency - accurately and dependably. *Before checking as or coal-fired units, consult local codes.
By adding a small pilot tube, which will fit into the kit case, air velocity measurements can be taken in heating, ventilating and air conditioning installations with the gages furnished. The Magnehelic Gage and No. 460 Air Meter have dual scales calibrated in inches of water and in feet per minute for air velocity. A conversion chart can be used to quickly convert velocity pressure indicated on the No. 171 Draft Gage to air velocity.
Taking a CO2 reading with No. 1101 CO2 indicator is quickly and easily done.
