GENERAL INSTALLATION INSPECTION
Recommended procedures for safety inspection of an appliance in accordance with the National Fuel Gas
Code ANSI Z223.1. The following procedure will help evaluate the venting system. It is intended as a guide
to aid in determining that the venting system is properly installed and is in a safe condition for continuous
use. This procedure should be recognized as a generalized procedure which cannot anticipate all situations.
Accordingly, in some cases, deviation from this procedure may be necessary to determine safe operation of
the equipment. If it is determined that a condition exists which could result in unsafe operation, the appliance
should be shut off and the owner advised of the unsafe condition. Corrections must be made before the
appliance is put into continuous operation. The following steps should be followed in making a safety
inspection.
Visually inspect the venting system for proper size and determine that there is no flue gas spillage, 1.
blockage, restriction, leakage, corrosion, or other deficiency which could cause an unsafe operation.
Insofar as practical, close all building doors, fireplace dampers, windows, and all doors in area in 2.
which the appliance is located. Turn on clothes dryers, any exhaust fans, such as range hoods and
bathroom exhausters so they operate at maximum speed. Do not operate a summer exhaust fan. If,
after completing Steps 3 through 6, it is believed sufficient combustion air is not available, refer to the
National Fuel Gas Code ANSI Z223.1, or any applicable local codes for guidance.
Place in operation the appliance being inspected. Follow the lighting instructions and adjust thermostat 3.
so appliance will operate continuously.
Determine that the pilot or burner is operating properly and that the main burner ignition operates 4.
satisfactorily, by interrupting and re-establishing the electrical power of the appliance in any convenient
manner. Test the pilot or burner safety device to determine if it is operating properly by extinguishing the
pilot or disconnecting the flame safety circuit and pressure switch sensing tube from the pressure switch.
Visually determine that the main burner is burning properly; i.e., no floating, lifting, or flashbacks.5.
Test for spillage at draft hood opening and burner inlet air location after 5 minutes of main burner 6.
operation. Use a draft gauge, flame of a match or candle, smoke from a cigarette, cigar or pipe. If
spillage occurs, adequate air is not available. Shut off heating appliance thermostat and check for
spillage around the draft hood and burner inlet air location after power venter has stopped operation. If
a flow reversal is noticed, house depressurization is occurring and make up air is required.
Turn on all fuel burning appliances within the same room so that they will operate at their maximum 7.
input. Then repeat Steps 5 through 6.
Return doors, windows, exhaust fans, fireplace dampers and any other fuel-burning appliances to their 8.
previous condition of use.
