Question

An item that is not an item of concern for a gas fired water heater is:

(a) the lack of an appropriate electrical disconnect
(b) a water heater that is set on the garage floor
(c) signs of flame roll out
(d) a bright yellow flame

Answer 1

For a gas-fired water heater, a bright yellow flame is not an immediate item of concern, unlike a lack of electrical disconnect, placement on a garage floor, or signs of flame roll-out, which pose significant hazards and require urgent attention.

Step-by-step explanation:

An item that is not an item of concern for a gas-fired water heater is a bright yellow flame. While a yellow flame may indicate an issue such as incomplete combustion or a lack of air, it is not necessarily a cause for immediate concern like the other options listed. Issues that warrant urgent attention include:

1. Lack of an appropriate electrical disconnect: This could lead to electrical hazards, particularly during maintenance.
2. A water heater set on the garage floor: This could be a fire hazard if flammable liquids were to spill and ignite.
3. Signs of flame roll-out: This indicates that combustion gases are escaping the heater, which could lead to carbon monoxide poisoning or fire.

Of all these potential issues, a bright yellow flame is considered the least critical, although it still might indicate a need for some adjustment or maintenance.
