Question

Signs of possible loss of heat exchanger integrity in a gas fired furnace include:

(a) Irregular flames patterns while the blower is operating
(b) Soot at the supply registers
(c) Excessive rusting or corrosion inside the heat exchanger
(d) All of the above

Answer 1

The signs of possible loss of heat exchanger integrity in a gas-fired furnace include irregular flame patterns, soot at the supply registers, and excessive rusting or corrosion inside the heat exchanger.

Step-by-step explanation:

The signs of possible loss of heat exchanger integrity in a gas-fired furnace include:

1. Irregular flame patterns while the blower is operating: This can be an indication that the heat exchanger is cracked or damaged, causing the flame to burn abnormally.
2. Soot at the supply registers: Soot is produced when the combustion process is incomplete, which can happen if the heat exchanger is compromised.
3. Excessive rusting or corrosion inside the heat exchanger: Rusting or corrosion is a sign of long-term exposure to moisture, which can weaken the heat exchanger and lead to loss of integrity.

If any of these signs are observed, it is important to have the furnace inspected and repaired by a professional to ensure safe and efficient operation.
