TROUBLE SHOOTING AND COMMON QUESTIONS
Q - I don't have any hot water when I open the tap!
A - Make sure there is gas, water and electricity to the Water Heater (the power is turned
on and the gas is turned on)
Q - When I was using the hot water, the water got cold!
A - If you adjusted the flow from the tap to lessen it, you may have gone below the
minimum flow required. The Water Heater requires a minimum flow rate to operate (see
specification page for flow rate of your unit). If you mix the water with a tap and attempt
to get a temperature well below the temperature being controlled by the unit, it may drop
the flow below the desired minimum flow rate. Simply decrease the temperature supplied
by the Water Heater at the control panel or increase your total flow.
Q - White smoke comes out of the exhaust!
A - During colder weather when the exhaust temperature is hotter than the air, the exhaust
fumes condense producing white steam.
Q - When I open a hot tap. I do not immediately get hot water!
A - Hot water must travel through your plumbing from the Water Heater to the faucet.
The time period for hot water to reach your fixture is determined by the amount of water
in your plumbing system between your water heater and the fixture, water pressure, flow
rate of fixture in use, etc.
Q - After I turn off the hot water tap, the fan on the Water Heater continues to run!
