The following information and warning must be considered in addition to the requirements defined in the NFGC and the NSCNGPIC. CARBON MONOXIDE POISONING HAZARD Failure to follow the steps outlined below for each appliance connected to the venting system being placed into operation could result in carbon monoxide poisoning or death.
4. The input rating of each space heating appliance is greater than the minimum input rating given in Table B for the local 99% Winter Design Temperature. Chimneys having internal areas greater than 38 square inches require furnace input ratings greater than the input ratings of these furnaces. See footnote at bottom of Table B, and Table B—Minimum Alowable Input Rating of Space-Heating Appliance in Thousands of BTU per Hour VENT HEIGHT (FT) 5. The authority having jurisdiction approves.
CHIMNEY INSPECTION CHART For additional requirements refer to the National Fuel Gas Code NFPA 54/ANSI Z223.1 and ANSI/NFPA 211 Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances in the U.S.A. or to the Canadian installation Code CSA-B149.1 in Canada. Crown condition: Missing mortar or brick? Rebuild crown. Yes No Is chimney property lined with clay tile liner? No Yes Is liner and top seal in good condition? No Repair liner or top seal or reline chimney as necessary.
4. Set the thermostat heat anticipator or cycle rate to reduce short cycling. Air for combustion must not be contaminated by halogen compounds which include chlorides, fluorides, bromides, and iodides. These compounds are found in many common home products such as detergent, paint, glue, aerosol spray, bleach, cleaning solvent, salt, and air freshener, and can cause corrosion of furnaces and vents. Avoid using such products in the combustion-air supply.

This furnace is equipped with manual reset limit switches in the gas control area. The switches open and shut off power to the gas valve if a flame rollout or overheating condition occurs in the gas control area. DO NOT bypass the switches.

Immediately increase to 5-inch or 6-inch vent connector outside furnace casing when 5-inch vent connector is required, refer to Note 1 above. 3.
1. Determine the correct gas input rate. In the U.S.A.: The input rating for altitudes above 2,000 ft. must be reduced by 4 percent for each 1,000 ft. above sea level. For installations below 2000 ft., refer to the unit rating plate. For installations above 2000 ft., multiply the input on the rating plate by the de-rate multiplier in Table 8 for the correct input rate. In Canada: The input rating must be derated by 10 percent for altitudes of 2,000 ft. to 4,500 ft.

Trial-for-Ignition Sequence- When the igniter warm-up period is completed the main gas valve relay contacts GVR close to energize the gas valve GV, the gas valve opens. The gas valve GV permits gas flow to the burners where it is ignited by the HSI. Five seconds after the GVR closes, a 2-second flame proving period begins.
the blower switches to COOL speed after a 3 second delay. If the R-to-W-and-Y-and-G signals disappear at the same time, the blower motor BLWM will remain on for the selected blower-OFF delay period. If the R-to-W-and-Y signals disappear, leaving the G signal, the blower motor BLWM will continue running the blower motor BLWM at HEAT speed after the selected blower-OFF delay period is completed. period at HEAT speed.
