II. SAFET Y SAFETY Adhere to the following warnings and cautions when installing, adjusting, altering, servicing, or operating the furnace. 2. Firmly touch a clean, unpainted, metal surface of the furnaces near the control. Any tools held in a person’s hand during grounding will be discharged. 3. Service integrated control module or connecting wiring following the discharge process in step 2. Use caution not to recharge your body with static electricity; (i.e.

gas, electrical, and drain trap and drain line connections. The combustion and ventilating air openings in the front and top panels of the furnace must never be obstructed. Refer to the unit Product Data Bulletin for minimum clearances to combustible surfaces. FURNACE SUSPENSION If suspending the furnace from rafters or joist, use 3/8" threaded rod and 2”x2”x3/8” angle iron as shown below. The length of rod will depend on the application and the clearances necessary.
Refer to the latest edition of the National Fuel Gas Code NFPA 54/ ANSI Z223.1 (Section 5.3), or CAN/CSA B149 Installation Codes (Sections 7.2, 7.3, or 7.4), or applicable provisions of the local building codes for determining the combustion air requirements for the appliances. This furnace must use indoor air for combustion. It cannot be installed as a direct vent (i.e., sealed combustion) furnace.
2. When communicating with the outdoors through vertical ducts, each opening shall have a minimum free area of 1 square inch per 4,000 BTU per hour of total input rating of all equipment in the enclosure. NOTE: The single opening must have a free area of not less than one square inch per 3000 BTU of the total input rating of all equipment in the enclosure, but not less than the sum of the areas of all vent connectors in the confined space.
All installations must be vented in accordance with National Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition. In Canada, the furnaces must be vented in accordance with the National Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and amendments. NOTE: The vertical height of the Category I venting system must be at least as great as the horizontal length of the venting system.
VII. MA SO NR Y CHIMNE YS MASO SONR NRY CHIMNEYS To rotate the induced draft blower counterclockwise proceed as follows: 1. Disconnect electrical power from furnace.

Appliances which burn propane (sometimes referred to as LP (liquefied petroleum)) gas are considered gas-fired appliances. CHECK 3 - CHIMNEY CROWN CONDITION. Damage from condensate usually shows up first in the crown. If any of the following trouble signs are present, the condition of the crown is not satisfactory: a) Crown leaning b) Bricks missing c) Mortar missing d) Tile liner cracked e) No tile liner f) Salt staining at mortar joints. (White stains, and mortar becomes sandy and/or erodes.
not suitable for use with gas-fired appliances. Flexible liners specifically intended and tested for gas applications are listed in the UL “Gas and Oil Equipment Directory”. (UL Standard 1777). For sizing of flexible liners, see Note 22 and the tables in the National Fuel Gas Code NFPA 54/ANSI Z223.1 - latest edition and in the National Standard of Canada, CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and amendments.
WARNING TO AVOID THE RISK OF ELECTRICAL SHOCK, WIRING TO THE UNIT MUST BE POLARIZED AND GROUNDED. 115 VOLT LINE CONNECTIONS Before proceeding with electrical connections, ensure that the supply voltage, frequency, and phase correspond to that specified on the unit rating plate. Power supply to the furnace must be NEC Class 1, and must comply with all applicable codes.
1. Measure resistance between the neutral (white) connection and one of the burners. 2. Resistance should measure 10 ohms or less. This furnace is equipped with a blower door interlock switch which interrupts unit voltage when the blower door is opened for servicing. Do not defeat this switch.
HIGH ALTITUDE DERATE When this furnace is installed at high altitude, the appropriate High Altitude orifice kit must be applied. This is required due to the natural reduction in the density of both the gas fuel and combustion air as altitude increases. The kit will provide the proper design certified input rate within the specified altitude range. High altitude kits are purchased according to the installation altitude and usage of either natural or propane gas.

A ground joint union, drip leg, and manual shutoff valve must also be supplied by the installer. In some cases, the installer may also need to supply a transition piece from 1/2" to another pipe size. When the gas piping enters through the right side of the furnace, the installer must supply the following fittings (starting at the gas valve): • 90 degree elbow. • Close nipple. • 90 degree elbow. • Straight pipe to reach exterior of furnace (Figure 19).

FURNACE SHUTDOWN XII. ST AR T-UP PR OCEDURE AND AD JUST MENT STAR ART PROCEDURE ADJUST JUSTMENT Furnace must have a 115 VAC power supply properly connected and grounded. Proper polarity must be maintained for correct operation. An interlock switch prevents furnace operation if the blower door is not in place. Keep the blower access door in place except for inspection and maintenance. This furnace is also equipped with a self-diagnosing electronic control module.
With Power and Gas Off: 1. Honeywell Model VR8205, or White-Rodgers Models 36E22, or White-Rodgers Model 36F22: Connect a water manometer or adequate gauge to the “inlet pressure tap” of the gas valve. As an alternative method, inlet gas pressure can also be measured by removing the cap from the drip leg and installing a predrilled cap with a hose fitting (Figure 26). With Power and Gas On: 2. Put furnace into heating cycle and turn on all other gas consuming appliances.
