question 4
1 pts
all of the following are common venting problems on gas and oil water heaters except
rust
poor slope
inadequate clearance from combustibles
vent connector is too long
vent connector manifolds with vent connector from furnace

Explanation:

Question 1

Gas - fired water heaters and boilers for space heating have gas piping, a gas burner, a cold water inlet pipe, a hot water outlet pipe, and a venting system. However, not all have a temperature/pressure relief valve set at exactly 210°F and 150 psi as settings can vary.

Rust is typically related to corrosion of the water - heater tank itself rather than being a common venting problem. Poor slope, inadequate clearance from combustibles, a too - long vent connector, and vent connector manifolds with the furnace vent connector are common venting issues.

Answer:

a temperature/pressure relief valve set at 210°F and 150 psi
