FIGURE 3 COMBUSTIBLE CLEARANCE FOR W24G, W30G AND W36G MODELS FIGURE 3A COMBUSTIBLE CLEARANCE FOR W42G, W48G AND W60G MODELS WARNING A minimum of one (1) inch clearance must be maintained between the supply air duct and combustible materials. This is required for the first three (3) feet of ducting. It is important to insure that the one (1) inch minimum spacing is maintained at all points.
9. CLEARANCES TABLE 2 MINIMUM INSTALLATION CLEARANCES Minimum clearances, as specified in Table 2, must be maintained from adjacent structures to provide t e l ) s l r i f adequate fire protection, adequate combustion air, and ) s l room for service personnel.

NATURAL GAS INPUT RATE 9. If you left water heater, dryer or range pilots on, allow for them in calculating correct furnace gas Natural gas heating value (BTU/cu. ft.) can vary input. A quick way is to allow 1,000 BTU per hour significantly.
21. STANDARD ORIFICE SIZING AND It is the installer’s responsibility to see that the furnace HIGH ALTITUDE DERATE input rate is adjusted properly. Derating must be achieved by reducing the size of the main burner This furnace is shipped with fixed gas orifices for use orifices.
22. CONVERSION OF GAS INPUT BTUH 2. Set balancing dampers in supply duct system. FROM HIGH TO LOW RATING 3. Check duct work for obstructions or leaks. All the derated WG series units are produced with 4. Make sure filters are clean and in place. maximum BTUH input orifices installed.
FIGURE 16 ACCESS INTERNAL FILTER THROUGH UPPER SERVICE DOOR 24. FILTERS HIGH PRESSURE SWITCH AND LOCKOUT SEQUENCE (Standard Feature) A 2" thick throwaway filter is supplied with each unit. This filter is installed by opening the main service door. If the high pressure switch opens, the compressor (See Figure 16.) contactor will de-energize immediately.

ALARM OUTPUT PHASE MONITOR Alarm terminal is output connection for applications All units with three phase scroll compressors are where alarm signal is desired. This terminal is powered equipped with a three phase line monitor to prevent whenever compressor is locked out due to HPC or LPC compressor damage due to phase reversal.
FIGURE 18 27. SERVICE AGENCY PROCEDURES TOP VIEW OF GAS CONTROL CAUTION Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. WARNING Follow these procedures before inspecting MIS-165 furnace.
ROUTINE MAINTENANCE WARNING 1. Air Filters – Check the condition at least monthly when the unit is in use, and replace as necessary. 2. Lubrication Requirements – The indoor circulating Disconnect electrical power before servicing air blower motor and outdoor circulating air fan unit.
