Multiple Unit Controls
For installation of multiple water heaters, ensure proper manifolding of the controls and common venting as outlined in the section below. Note that up to 20 water heaters can have maniolded gas lines, water lines, and controls, however, vent pipes can only be common vented for a maximum of 2 water heaters. For more than 2 water heater installations, multiple vent runs will be required. For manifold systems with built-in recirculation pump, the first water heater in the series must contain the built-in recirculation pump to ensure proper operation. Additional water heaters in the series can be recirculation or nonrecirculation based on application requirements.
This water heater includes multiple unit controls to manifold up to 20 water
heaters together.
To accomplish multiple unit controls, a RJ25 communication cable(s) is
required. Contact a store where tankless water heaters were purchased to
purchase the RJ25 communication cable(s).

Open all hot water faucets. Run the water until it is COLD; then shut off the
faucet.
Close the water shut-off valve.
Find the water filter(s) and the water drain plug at bottom of the water
heater.
Only applies to built-in pump models.
Using a suitable container to catch the water, remove the water drain plug
located at bottom of the water heater, and the water filter(s). 
Connect a garden hose to the drain valve on the hot water outlet line and place the other end in a suitable drain. Open the drain valve until all the water has drained from the water heater. Leave water heater as is until placed back in service.
CAUTION:
Even when drained properly, a small amount of water will remain in the water
heater. In cold weather conditions, this water can freeze. If this happens,
allow the defrost protection on the water heater at least 30 minutes to melt
the frozen water. The water heater will not work properly until this water is
thawed.
To put the water heater back in service:
Disconnect drain hose. Make sure the drain valve is
closed.
Reinstall the water filter(s), and the water drain
plug.
Open the water shut-off valve.
Open all hot water faucets and let run until all air has been purged from the
lines. Close all hot water faucets.
Open the gas shut-off valve(s).
Plug in the power cord or reconnect the power supply at the circuit breaker box.
Standard Drain Method
Service isolator valve kits may be purchased from the manufacturer,
distributor, or place of purchase.
The kits include two full-port isolation valves to be used in the inlet and
outlet water lines. These kits provide a means for full diagnostic testing and
ease of system flushing and draining.
Flushing of the Heat Exchanger
Flushing of the heat exchanger is required for maintaining optimal efficiency.
Flushing frequency is based on water conditions and average usage and should
be conducted annually or as recommended by a professional. Failure to flush
the unit consistently could result in higher operation costs or premature unit
failure.
Flush kit (RTG20124) is available to conduct flushing of the heat exchanger.
Contact a store where tankless water heater is purchased to purchase the flush
kit. 
Set the highest available set point on a display. It should be 140F (60C).
Follow the instructions at “Setting the Water Temperature” in this use and
care manual to change set point.
Unplug the water heater from electrical outlet or disconnect the power supply
at the circuit breaker.
Follow the instructions at “Draining the Water Heater” in this use and care manual to drain the water heater, and close at cold and hot service valves V3 and V4.
Connect one side of hose of a circulating pump contained in the flush kit to
cold service valve V2, and the other side to the pump outlet. 
Connect one side of the drain hose to hot service valve V1, and place the
other side in the bucket.
Pour no more than 2 gallons of virgin food grade white vinegar into the
bucket, and place the circulating pump in the bucket. 
Open cold and hot service valves V1 and V2.
Connect power to the pump and allow to circulate vinegar for 45 minutes. After
a minimum of 45 minutes unplug the circulating pump
Remove the drain hose from the bucket and route it to suitable drain. Close
cold service valve V2, and open service valve V4 to flush the water heater
with water. DO NOT open hot water service valve V3 at this time. Allow water
to flow out of house for 5 minutes to rinse cleaning solution. 
Close hot service valve V1, and open valve V3.
Disconnect both hoses from service valves. 
Follow the instructions at “Water Filter Cleaning” in this use and care manual to clean the water filter, and plug in the power cord or reconnect the power supply at the circuit breaker.
NOTICE:
Recommend 120°F for the temperature setting when flushing procedure is
completed.
