Protecting the Water Heater from
Freezing
Caution
•To protect the water heater from freezing, recommend
the use of a direct vent exhaust and intake system. Ensure
that the exhaust vent pipe and the air intake pipe are both
connected directly from the collars on the top of the water
heater to the outdoors. This type of vent system minimizes
air movement within the water heater.
•Freezing damage usually occurs due to back-drafting
caused by negative pressure in the building. This is not a
manufacturing defect, and therefore, Vesta will not warrant
any damage due to freezing. The installer is responsible
for ensuring that there is sucient make-up air to avoid
such a situation, and the owner is responsible for ensuring
protection against freezing.
To protect the water heater from freezing, follow these guidelines:
•If the water heater will not be used for an extended period of
time, drain the water heater.
•Do not unplug the power supply cord, except for routine
maintenance. The water heater has a freeze protection function
that warms up the water heater when the temperature inside
the water heater becomes lower than 43°F (6°C). The freeze
protection function will operate regardless of whether or not
the front panel is turned on or o, as long as the power supply is
still connected.
•If the power or gas supply must be disconnected for an
extended period, drain the water heater.
•Protect and insulate all water pipes, including the condensate
trap drain line, from freezing.
Notice
If you suspect that the water heater is frozen, contact an authorized
technician or licensed professional.
Maintenance Schedules
Caution
A qualied technician should inspect the water heater at the
beginning of every heating season and/or when there is a
problem.
Owner maintenance
Daily
•Check that the area where the water heater is installed is free of
combustible/ammable material and air-contaminants.
•Visually inspect the exterior of the water heater.
Monthly
•Inspect the condensate trap and the PVC ttings.
•Visually inspect the piping (water and gas) for leaks.
•Visually inspect the vent piping for signs of leakage and
blockage.
Every 6 months
•Inspect the piping (water and gas) for leaks.
•Inspect the vent piping for leakage and blockage.
•Test to make sure the pressure relief valve is operating properly.
Service technician maintenance
Periodically
•Inspect the interior of the water heater.
•Clean the condensate trap and ll with fresh water.
•Clean the air intake lter.
•Check for leaks (gas, water, ue, and condensate).
•Check the system pressure (gas, and water).
•Check ignition and ame rod.
•Check wiring connections.

Troubleshooting
Basic Problems
If there is a problem with the water heater, refer to the following table for possible remedies. For minor problems, turning the water heater o
and then turning back on may resolve the situation. If turning the water heater o and on and attempting the remedies suggested below do not
resolve the problem, contact an authorized technician, licensed professional, or technical support at 1-800-761-0053.
Category Problem Possible Cause(s) What to Do
Initial
operation
Water heater does not ignite
when water is running.
•Are the gas and water pipes connected
properly?
•Check for correct plumbing or crossed piping to
the unit.
•Check the water inlet lter for debris.
Unit attempts to ignite but
fails
•Is there air in the gas line?
•Is the gas supply pressure sucient?
•Turn o the water heater and then turn it back on.
•Have your installing contractor check the gas
supply pressure.
•Ensure the water heater is powered by 120 V-1
PH-60 Hz.
Temperature
Hot water is not produced
when a faucet is opened.
•Are the gas and water supply valves fully
open?
•Is the water supply cut o to the household?
•Is gas being provided by the gas meter?
•Is there enough gas (for LP) in the tank?
•Is the water inlet lter clogged?
•Is the power button turned on?
•Fully open the gas and water supply valves.
•Check the water inlet lter for debris.
•Check the power status of the water heater.
No water is available when a
faucet is opened.
•Is the water supply cut o?
•Is the water heater frozen?
•Are the pipes frozen?
•Open the cold water supply.
•Check if the water heater and/or the pipes are
frozen.
The hot water is not at the
correct temperature. •Is the hot water faucet suciently open? •Fully open the hot water faucet.
Water takes a long time to
become hot after opening
the hot water faucet.
•Have you allowed enough time for the cold
water in the pipes to drain out?
•Even though the unit may be operating properly,
the cold water contained in the piping will need to
ow through the faucet before the hot water can
reach the faucet. Wait for several minutes.
The water is too hot.
•Are the gas and cold water supply valves fully
open?
•Is the water temperature setting appropriate?
•If the cold water supply temperature is too high, it
is possible for the temperature to be higher than
the temperature set on the front panel. Decrease
the water temperature on the front panel.
•If only a small amount of hot water is required, it is
possible for the temperature to be higher than the
temperature set on the front panel. Decrease the
water temperature on the front panel.
•If the cold water supply passes through a solar pre-
heating system, it passes for the delivered water
temperature to be higher than the temperature set
on the front panel.
The water is not hot enough.
•Are the gas and cold water supply valves fully
open?
•Is the water temperature setting correct?
•Fully open the gas and cold water supply valves.
•Check the water temperature setting.
Fluctuation in hot water
temperature. •Is the water inlet lter clogged? •Clean the water inlet lter for debris.
