Area of the ventilating opening into the furnace room shall be not less than twice the area of the flue outlet. CLEARANCES Unless materials used in building construction, and/or application of the heating equipment are of such a nature that local authorities to require otherwise, the clearance about the furnace should be: Ready access shall be provided for all electrical components in service. Draft regulator shall bear the listed marking. ABOVE-6”, SIDES AND REAR-6”, FRONT-48”, FLUE PIPE-18”.
inches at the stack. The draft may be accurately measured with any good draft gauge. GAS Excessive draft causes high stack temperatures and consequently a waste of fuel. Therefore, a reliable draft regulator is strongly recommended for practically all installations. Proper, uniform draft insures efficient, economical operation of the burner. A good draft regulator will usually pay for itself in a short time through a substantial savings in fuel costs. D.
Air for Combustion – There must be openings into the furnace room to admit free air to maintain combustion, minimum opening of not less than twice the area of flue outlet of furnace. E. Burner Installation OIL Equipment – The following equipment shall be available on each oil burner installation before the tests are started: 1) Where the oil rate is not indicated on the nozzle tip, a suitable device for determining the rate in terms of gallons per hour fed to the burner shall be used.
Adjusting the Burner – After the installation of the burner, tank, and controls have been completed and all wiring carefully checked. 1) Leave line switch open and set thermostat well above room temperature. 2) Make sure that the resetting device on the control panel is in operating position. 3) Set can at gauge port or bleeder tube opening to catch oil. Close line switch and allow burner to pump oil until flows clear.
MAINTENANCE Servicing the Burner – After the burner installation has been put in service, it should be rechecked during the first two weeks to make certain that it is functioning properly. Note the combustion is proper and there are no gas or oil leaks, also that the different controls perform correctly. Employ only qualified personnel to service heating equipment. For safety, the main power switch must be in the “OFF” position.
