4. Verify natural gas input rate by clocking meter.

NOTE: Gas valve regulator adjustment cap must be in place for proper input to be clocked.

a.Turn off all other gas appliances and pilots.

b.Run furnace for 3 minutes in heating operation.

c.Measure time (in sec) for gas meter to complete 1 revolu- tion and note reading. The 2 cubic feet dial provides a more accurate measurement of gas flow.

d.Refer to Table 8 for cubic ft of gas per hr.

e.Multiply gas rate (cu ft/hr) by heating value (Btu/cu ft) to obtain input.

If clocked rate does not match required input from Step 1, increase manifold pressure to increase input or decrease manifold pressure to decrease input. Repeat steps b through e until correct input is achieved. Re-install regulator seal cap on gas valve.

5.Set temperature rise.

The furnace must operate within the temperature rise ranges specified on the furnace rating plate. Do not exceed tempera- ture rise range specified on unit rating plate. Determine the temperature rise as follows:

a.Place thermometers in return and supply ducts as close to furnace as possible. Be sure thermometers do not see radiant heat from heat exchangers. Radiant heat affects temperature rise readings. This practice is particularly important with straight-run ducts.

b.When thermometer readings stabilize, subtract return-air temperature from supply-air temperature to determine air temperature rise.

NOTE: Blower access door must be installed for proper tempera- ture rise measurement.

NOTE: If the temperature rise is outside this range, first check: 1.) Gas input for heating operation.

2.) Derate for altitude if applicable.

3.) Return and supply ducts for excessive restrictions causing static pressures greater than 0.50-in. wc.

4.) Dirty filter.

Venting Notes for Fig. 26-38

1.For common vent, vent connector sizing and vent material: United States, latest edition of the National Fuel Gas Code (NFGC), ANSI Z223.1/NFPA 54. In Canada, latest edition of the National Standards of Canada, Natural Gas and Propane Installation Code (NSCNGPIC), CSA B149.1-00.

2.Immediately increase to 5–inch vent connector outside furnace casing when 5-inch vent connector required, refer to Note 1 above.

3.Side outlet vent for upflow and downflow installations must use Type B vent immediately after exiting the furnace, except when KGAVG0101DFG is used in the downflow position.

4.Type B vent where required, refer to Note 1 above.

5.4” single wall (26 ga. min.) vent must be used inside furnace casing and when the KGAVG0101DFG Downflow Vent Guard Kit is used external to the furnace.

6.Accessory Downflow Vent Guard Kit, KGAVG0101DFG required in downflow installations with bottom vent configuration.

7.Chimney Adapter Kit required for exterior masonry chimney applications. Refer to Chimney Adapter Kit, KGACA02014FC and KGACA02015FC for sizing and complete application details.

8.Secure vent connector to furnace elbow with (2) corrosion-resistant sheet metal screws, spaced approximately 180° apart.

9.Secure all other single wall vent connector joints with (3) corrosion resistant screws spaced approximately 120° apart. Secure Type B vent connectors per vent connector manufacturer’s recommendations.

Disconnect 115-v electrical power before changing speed tap. Failure to follow this warning could result in personal injury.

c. Adjust air temperature rise by adjusting blower speed. Increase blower speed to reduce temperature rise. Decrease blower speed to increase temperature rise.

d. Turn thermostat down below room temperature and re- move blower access door.

e. To change motor speed selection for heating, remove blower motor lead from control HEAT terminal (See Fig. 39.) Select desired blower motor speed lead from one of the other terminals and relocate it to the HEAT terminal (See Table 7 for lead color identification). Reconnect original lead to SPARE terminal.

f.Repeat steps a through e.

g.When correct input rate and temperature rise is achieved, turn gas valve ON/OFF switch to OFF.

h.Remove manometer or similar device from gas valve.

i.Re-install manifold pressure tap plug in gas valve.

Failure to reinstall manifold pressure tap plug in gas valve will result in fire, explosion, personal injury, property damage or death.

j.Re-install blower access door if removed.

k.Turn gas valve ON/OFF switch to ON.

Recheck temperature rise. It must be within limits specified on the rating plate. Recommended operation is at the mid- point of rise range or slightly above

6. Set thermostat heat anticipator.
